Within the defence community Defence Business Services National Security Vetting (DBS NSV) provides National Security Vetting (NSV) for the 3 armed services, Ministry of Defence (MOD) civil servants and defence contractors, as well as providing NSV for MOD trading funds and other government departments.

Privacy and Data Protection

The Data Protection Act 1998 came into force on 01 March 2000 and sets out rules for processing personal information and, with some exceptions, applies to vetting paper records as well as those held on computers.

We are required to hold your personal data lawfully, to ensure that the data is accurate and kept up to date and is not used for any purpose other than national security vetting. The security questionnaires show when and under what circumstances personal data may be shared and the checks that will be made. Personal data will not be passed outside the security community, (including to police authorities) except in exceptional circumstances.

Retention periods

Vetting records are generally kept within DBS NSV for an individual’s working life. The standards of secure storage and confidentiality described above are kept for the entire retention period, whether or not the Subject is a current National Security Vetting holder and irrespective of the sensitivity of the personal data.

All personal information gathered during the vetting process is handled in the strictest confidence. In a very small number of cases, where serious risks have been identified we may discuss the case with the relevant security authorities. In a few cases, and with the permission of the person being vetted, line management may be given some relevant information and be asked to help manage the risk. There is an extremely remote possibility of disclosure of vetting information in connection with criminal or civil proceedings. If you have any concerns about confidentiality please contact us for advice.


If you need access to ‘Secret’ or ‘Top Secret’ information, or have a proximity to public figures who have been assessed to be at particular risk from terrorist attack you need the appropriate level of national security clearance. You will be going through the vetting process if you are either being considered for a post where you will have access to highly sensitive information or assets, or because we are looking at your current clearance to allow you to carry on in your present post or to allow you to move to another post.

There are 3 security levels:

Counter Terrorist Check (CTC): is carried out if an individual is working in proximity to public figures, or requires unescorted access to certain military, civil, industrial or commercial establishments assessed to be at particular risk from terrorist attack.

Security Check (SC): determines that a person’s character and personal circumstances are such that they can be trusted to work in a position which may involve access to ’Secret’ information.

Developed Vetting: (DV) in addition to SC, this detailed check is appropriate when an individual has long term, frequent and uncontrolled access to ‘Top Secret’ information. There is also Enhanced DV.

If you have a criminal record this will be judged on its own merit. It is important to be completely open about any criminal history, you should include details of any spent convictions and police cautions in your security questionnaire.

Any attempt to hide information could be taken as evidence of unreliability/dishonesty and may affect your clearance.

More about Developed Vetting

DV is the most thorough method of security vetting. The DV process includes a check of your identity documents and employment and education references.

We will carry out criminal records and credit reference checks and a check against security service records. We will also double check some of the references by writing to or interviewing the individuals who provided them. The individual being vetted will also be interviewed by a Vetting Officer.

Getting a Security Clearance

First, you need a sponsor. Individuals cannot ask for a security clearance unless they are sponsored, and you will not be sponsored unless the company that is employing you (or you yourself, if you are a consultant) are contracted, or are in the process of being contracted, to work on 1 or more specific MOD classified projects.

If the company is LIST X, it will be able to sponsor your clearance itself. If you are employed by a company that is subcontracted by a LIST X main contractor, the LIST X firm will also be able to sponsor you. If there is no LIST X sponsor, the MOD authority responsible for placing the contract will sponsor your clearance.

Note: Due to security reasons we are unable to populate an individual’s form from information previously provided so even if you have been vetted before you will need to go through the process again.

Rationale for requiring a sponsor

Government resources are committed every time a clearance is requested so it is essential that this is used correctly. A sponsor is usually your human resources/personnel office, line manager or company security controller.

Your sponsor is someone who is required to verify that the Baseline Personnel Security Standard (BPSS) was done prior to your employment and can also verify that your role requires you to have the identified level of clearance.

Being security cleared does not provide a guarantee of future reliability and all security clearances are kept under review to ensure that the necessary level of assurance is maintained. This review is carried out by government departments and government sponsored contractors who are responsible for the oversight and aftercare of individuals granted a security clearance. It is also the sponsor’s responsibility to inform us when a subject ceases to require security clearance.

This overview would not be possible in the case of private individuals. Additionally, Defence Business Services National Security Vetting (DBS NSV) is funded and staffed to meet forecast requirements for security vetting. It cannot accommodate large numbers of additional clearances on an ad hoc basis.

Medical information

The eform and security questionnaire explains how we collect and guard medical information. To enable us to fully assess an individual’s suitability to handle sensitive information, our vetting medical adviser may contact your doctor (or military medical officer) for confirmation on whether you have suffered from certain medical or psychological conditions. We may also request that you have a medical examination.

If you do not allow us access to your medical reports we can refuse your vetting clearance.

Personal Finance

The reason we require a financial questionnaire can vary. One of the standard checks we carry out when someone is being security cleared is with a credit reference agency. If you have been living overseas, or in service or similar accommodation, we may have little or no information about you and we will be unable to assess your suitability for clearance. The completed questionnaire enables us to proceed with your clearance.

Sometimes, where you have told us about financial problems in the past, you will be sent a questionnaire so that we can assess your current situation.

If you or your partner have previously been or are currently in serious financial difficulty, or show signs of financial irresponsibility, you could be vulnerable to pressure or bribery.

Debts such as mortgages, loans or credit cards will not normally affect your suitability to hold a DV clearance as long as you are able to keep up the repayments properly. However your financial situation will be carefully considered and each case will be judged on its merits.

We may make enquiries if you seem to have large amounts of savings that you cannot explain. The Vetting Officer will ask you to bring some financial and other documents to the interview (see below for details).

If you have a partner we recommend you share all this information with them. Without your partner’s details we may have insufficient information to make a decision on your clearance. Please be assured that we do not retain any bank or credit card numbers.

You must complete all the questions in the questionnaire. An incomplete questionnaire will be returned to you and this will delay the vetting process. It is essential that you are open and honest in your answers.
Please do not lie or hide information. Doing so is likely to result in your clearance being refused.

We cannot provide you with financial advice or send you a copy of the information received from the credit reference company. Organisations that may be able to offer advice include the Citizens’ Advice Bureau, StepChange, the National Debtline or ‘Experian’ (who, for a small fee they will provide you with your credit record).

The Interview

The interview is the main worry for most people who go through the DV process. The subject interview is likely to be long; up to 3 hours is not unusual.

Interviews are normally carried out at work during working hours. In some cases the Vetting Officer may ask to interview you at your own home.

You can have a friend, colleague or relative at the interview. Most people prefer to be interviewed alone in view of the sensitive nature of the things that will be discussed.

It will cover most areas of your life. The vetting officer will build as complete a picture of you as is possible. This is so we can make sure that you will be able to cope with access at the highest levels and will not become a security risk and a threat to national security.

We consider your loyalty, honesty and reliability, and whether you could be particularly vulnerable to bribery or blackmail. We will question you about your wider family background (relationships and influences), past experiences (if any) of drug taking, financial affairs, general political views (though not which Party you support), hobbies, foreign travel and so on.

The interview will be very searching, but it is not an interrogation and should not feel like one. Some of the questions will be intrusive but are asked because we are trying to find out if you are vulnerable to pressure. If you have any doubts about the relevance of some questions you should ask the Vetting Officer why they are asking the question.

You should be completely honest. The Vetting Officer will be experienced and it is unlikely that they will be shocked or surprised by anything you say. Please do not lie or hide information.

We will probably refuse your clearance, or subsequently withdraw it, if we later find out that you have lied or withheld information. If you tell the Vetting Officer about a previously undisclosed criminal offence the matter will be included in their interview report and will be assessed accordingly. A decision will then be made on what action is to be taken.

Sometimes people have aspects of their lives that they are ashamed of or embarrassed to tell us about. Usually these are of little or no security significance. They will generally not stop or restrict the granting of a security clearance.

If you would feel more comfortable talking about certain matters with a different Vetting Officer (someone of your own sex, age profile, or ethnic group, for example), let us know and we will try to arrange this for you (Telephone: 01904 662644).

If you need any special facilities to enable the interview to take place, please tell the Vetting Officer when they contact you.

Interview Documentation

The following list is not exhaustive but these are the documents that the Vetting Officers commonly ask to see (where appropriate). Please note that all documents must be originals.

Any additional requirements will be notified to you by the Vetting Officer, normally in advance of the interview. Any delay in providing these documents is likely to delay your clearance.

General documents:

evidence of identification, for example: birth certificate, passport*, driving licence, identity card

Deed Poll or certificate of declaration in respect of any change of name

naturalisation or registration certificate

adoption certificate

marriage certificate/civil partnership documents

Decree Absolute or Nisi

separation or maintenance Orders

HM Forces (HMF) discharge certificate

curriculum vitae

utility bills

*passport is also required as evidence of travel.

Financial documents (in respect of you and your partner):

bank current accounts (statements for the last 3 months)

details and statements for the last 3 months of all charge and credit cards, store and mail order accounts

details and statements of all loans and hire purchase agreements

details of mortgage and copy of last mortgage statement

details of any County Court Judgements

last 3 pay statements

documents and statements connected with savings and investments

any other documents which support or help to explain any figures on the Financial Questionnaire

Decision Process

The decision to grant a security clearance will be based on the available information obtained during the vetting process.

Unless you are being recruited directly into a security cleared job, you will be told the outcome of the vetting process by your sponsor (usually your human resources/personnel office, line manager or company security controller).

If you are refused a clearance you will be told what actions are available to you.

Transfer of a NSV clearance within MOD organisations and defence contractors

If you hold a NSV clearance and you transfer or move to a new organisation, there may be a continuing requirement for them to hold a security clearance either at the same or lower level. For example, a serviceman or woman leaves one branch of HMF and transfers to another service or moves on to a role in defence industry or as a MOD civilian. Similarly an employee of a defence contractor moves to another job and is employed by a different contractor.

In these situations the new employing sponsor submits a request to us for the security clearance to be transferred. The ‘Transfer’ request allows us to assess the individual’s suitability for transfer of the security clearance and enables the outcome to be recorded against the correct sponsor. The request can be for the security clearance to be at the same level issued to the original sponsor or at a lower level, based on the needs of the new sponsor. An example of this would be when the SC element of a DV clearance is needed by the new sponsor. It is for the sponsor to set out what is required and for us to consider whether the request for transfer can be met.

Criteria for Transfer

Before a transfer can take place the following criteria will need to be met.

Security Check and Counter Terrorist Checks - Transfer

a. The SC must not be more than 10 years old for directly employed MOD, HMF or List X contractor’s personnel, or for an employee of a Non List X contractor, more than 5 years old (for SC) or 3 years old (for CTC). If a direct employee of MOD, HMF or List X transfers to a Non List X contractor, the security clearance can be issued for the remaining duration of the extant clearance or 5 years (SC) or 3 years (CTC), from the date of the transfer, whichever is the lesser.

Developed Vetting - Transfer

b. The DV clearance must not be more than 7 years old for directly employed MOD or HMF (excluding reservists) personnel or 7 years for List X and 3 years for Non List X contractors’ staff. If a direct employee of MOD or HMF (excluding reservists) transfers to List X, the DV can be issued for 7 years from the original start date. Non List X organisations cannot hold clearances in their own right so the transfer would need to be applied for by the contracting company or IPT.

c. The expiry date of the SC must not have been exceeded. However, if it is established that the vetting subject has remained in continuous employment an extension of up to 6 months may be permitted to allow time for a review to be actioned. In this instance the extended DV clearance may be transferred.

d. You must take up the post for which you were originally DV cleared within 12 months of the clearance being issued and you must not have been out of a post, for which they required DV clearance, for more than 12 months.

Counter Terrorist Check, Security Check and Developed Vetting, common criteria - Transfer

e. No more than 12 months has elapsed since you left the organisation for which the clearance was originally granted or subsequently transferred to and joining the one applying for the latest transfer.

f. No more than 6 months of a 12 month period between leaving one employment and joining another has been spent living overseas.

g. You must not have undergone any of the following changes in your personal circumstances since the application for the security clearance for which a transfer under consideration was made: marrying, remarrying, entering into a civil partnership, setting up a stable unmarried relationship which includes living with someone as a couple.

However, if a change of personal circumstances (CPC) questionnaire has already been completed and has been satisfactorily processed, the transfer should still be able to go ahead. Otherwise, it may be possible for the transfer process to be paused while the vetting subject completes a CPC form.


Once a prospective sponsor has satisfied themselves that a transfer of clearance is feasible they should submit a Transfer Request Form via the NSVS Sponsor Portal - you will require a valid sponsor account in order to access this facility.

Please select the ‘other services’ option on your home page and select relevant transfer option in the Vetting Service section.

No email requests are accepted all transfer requests must go through the portal.

Existing clearances and aftercare

Aftercare is the term we use for the maintenance of effective personnel security. Its purpose is to investigate and monitor anything of continuing security concern, between periods of normal review, which could affect an individual holding a NSV clearance.

The CTC, SC and DV security vetting processes give an assurance of an individual’s suitability for access to sensitive government information or other valuable assets. However, vetting alone does not give a guarantee of future reliability. It is important that personnel security continues after the initial security clearance is approved and that any new information or concerns that may affect the reliability of a person are brought quickly to the attention of the appropriate authorities. This is achieved through a combination of aftercare and the routine security clearance review procedures.

Aftercare also includes any risk management measures put in place to monitor the security reliability of individuals who hold a security clearance.

Extraction of SC from DV clearance

Where a DV clearance has expired, or is no longer required, for customers requiring the underlying SC, please select Vetting Service Aftercare - Transfer Extract and submit.

Change of personal circumstances

If you hold a security clearance and, you have a responsibility to report to us any change in your circumstances that might affect it. You must tell us if any of the following occur:

you marry, remarry, enter a civil partnership or set up a stable unmarried relationship, living with someone as a couple

you are arrested, cautioned or convicted of a criminal office

there is a significant change in your financial situation

you acquire a new nationality, or renounce one that you have held

if you hold a DV clearance, you must notify us when anyone aged 18 or over begins living with you in your household, or when a young person who is already living with you reaches 18 years of age. For this purpose, ‘household’ means a group of people living at the same address who share cooking facilities and share a living room, sitting room or dining area: it does not include people with whom you live in a hostel or in shared service accommodation, Police etc.

Security Appraisal Form (SAF)


The initial component checks that comprise Security Vetting clearances can only provide a snapshot at the time they are done. It is essential therefore that clearances are actively maintained via effective on-going personnel management processes, which at the DV level will include an annual security appraisal.

Line managers or supervisors of staff who have undergone DV or who are supervising contractors who have DV clearance should be aware of their responsibilities with regard to regularly engaging staff on security issues and the requirement to complete the annual security appraisal process.

Managing security clearances requires active conversations between individuals and managers throughout the year and prompt reporting of any issues of concern as they arise. The SAF should be completed by all individuals who hold DV clearance to provide assurance that they are being supported and monitored as is appropriate for individuals with access to sensitive assets. This process may be extended to other vetting levels, for example SC or Enhanced SC.

Basic Principles

This applies to all vetted staff, be they civil servants, crown or public servants or contractors. The Basic Principles to take into account are:

On appointment, all staff and contractors in a vetted role should be briefed by their Line Manager, Supervisor or Security Controller on the security requirements specific to their role and the risks that NSV and other local security controls are intended to mitigate. Line managers should be satisfied that vetted staff understand their security responsibilities and the consequences of not meeting them. All DV staff and their managers will have received a standard letter outlining their responsibilities when they are vetted which should be issued as provided to all relevant individuals. Individuals should also receive a security induction from their Line Manager (or Security Unit/Security Controller), the completion of which should be recorded as per local procedures.

All vetted subjects (DV, SC and CTC) must report any relevant change in their circumstances that could have a bearing upon their clearance. Details of these relevant changes are explained in the ASAF but can be found under the ‘Process for DV - Individuals’ area of this page.

To maintain a clearance, an annual security clearance review must be completed by DV staff (and staff with additional or Enhanced SC) and their Line Managers, Supervisors or Security Controller. This includes all DV or Enhanced SC contractors and their Line Managers, Supervisors or Security Controllers.

If the annual review process has not been completed by DV (or Enhanced SC) staff, this will bring into question the individual’s suitability to retain security clearance. Departments and industry partners will have discretion to suspend or lapse an individual’s clearance as appropriate (industry partners should work with the relevant Government department to agree the best approach and ensure relevant information on individual cases is shared). In all instances where no action has been taken to complete an ASAF – following reasonable reminders – departments will be expected to take action, including to suspend or lapse an individual’s clearance where appropriate.

Line Managers, Supervisors or Security Controllers should monitor behaviour that could potentially impact on the security of the organisation. For example, signs of inappropriate behaviour or negligent practices contrary to security arrangements. This is an ongoing responsibility that is part of good line management and not just a requirement in relation to completion of the ASAF process.

Whilst there is no fixed requirement to complete an annual security clearance review for SC, CTC and BPSS staff, local guidance may expand to include these groups as appropriate. Any security concerns in respect of staff generally should be reported to the local security unit who will record it and take follow up actions where appropriate.

Line Managers, Supervisors or Security Controllers are not Vetting Officers but should be expected to exercise both a duty of care for staff and be mindful of potential security risks to the organisation. The ‘Maintaining Security Clearances - Guidance for Staff and Contractors’ and ‘Maintaining Security Clearances - Guidance for Line Managers/Supervisors’ leaflets found on Gov.uk provide common sense guidance to support this process.

Whilst vetting confidentiality must be maintained, organisations must ensure any relevant information is shared appropriately between vetting units, HR and Line Managers to help manage staff and staff performance in a joined up and holistic way.

The security appraisal requires the Line Manager, Supervisor or Security Controller to make an assessment of an individual’s continuing suitability to hold DV (or Enhanced SC). Where there are issues of concern the line manager may be interviewed (or ask to be interviewed) by the security unit/security controller to further explain concerning or complex areas.

Process for DV

As a minimum the security appraisal should be completed on an annual basis. The individual (vetted subject) is responsible for completing their part of the form and for ensuring their Line Manager, Supervisor or Security Controller completes their part.

Individuals (clearance holder)

Individuals should think about their security clearance as a credential they must maintain – whilst there are formal review periods, clearances may be reviewed, suspended, lapsed or be withdrawn at any stage if the organisation no longer has the necessary confidence or assurance in the individual. This is especially so in respect of DV clearances, which give individuals access to the most sensitive assets. Individuals should be aware that they must exercise discretion, good judgement and apply the necessary security controls as an ongoing requirement. Each individual is responsible for reporting Change of Personal Circumstances to their local security unit or directly to the vetting provider in a timely manner. The type of changes that should be reported will include:

if you get married, enter a Civil Partnership or start living with a partner as a couple

if you divorce or terminate a Civil Partnership

if you change your name for any reason

if a new co-resident age 18 or over begins living with you in shared accommodation

if you have had a substantial change in your financial circumstances (for example, you have been declared bankrupt, have received a sizeable inheritance or your financial circumstances have been impacted by divorce or dissolution of a civil partnership)

if you have received a criminal conviction or have been arrested or cautioned by the police (including by military police if relevant);

if you change your nationality, including naturalisation, acquire a new nationality/dual nationality or revoke a nationality/dual nationality.

if in doubt individuals should speak to their Line Manager, Supervisor or Security Controller or directly to the local security team

Line Managers, Supervisors or Security Controllers

Line Managers, Supervisors and Security Controllers are expected to exercise a duty of care for their staff and to be mindful of the potential security risks associated with issues such as personal relationships, health, debt, bereavement or extremist views and also to meet their obligations to the organisation in mitigating risks against assets (including information) arising from bad security behaviours.

Line Managers, Supervisors or Security Controllers must complete the annual security clearance review for DV staff and contractors.

The clearance level for each post should also be reviewed regularly to ensure that it is appropriate. Where security vetting requirements change, the appropriate notification must be passed to security and HR areas.

All security appraisals will be looked at and may prompt a request to discuss issues with the local security unit. Any concerns about completing the form should be addressed to local security units. If there are no areas of concern then no further action needs to be taken once the form is completed.

Process for Enhanced SC

Individuals who hold Enhanced SC clearance and their Line Managers, Supervisors or Security Controllers should follow the process for DV staff as set out above.

Process for Counter Terrorist Checks (CTC) and Security Check (SC)

Individuals (clearance holder)

Individuals retain a responsibility to meet the security practices of their area at all levels of clearance.
They should:

ensure that their contact details are up to date on HR systems and that they notify their local security unit, vetting provider or security controller of any change in role or contact details

exercise discretion, good judgement and apply the necessary security controls as an ongoing requirement. These behaviours and standards are summarised in the ‘Maintaining Security Clearances - Guidance for Staff and Contractors’ and ‘Maintaining Security Clearances - Guidance for Line Managers/Supervisors’ leaflets found on Gov.uk which provide common sense guidance to support this process

discuss concerns with line managers or local security areas at the earliest opportunity about events or changes in their lives that have led (or could lead) to someone exerting pressure to extract information, allow unauthorised parties access to assets etc

take action where other members of staff are acting oddly or in a way that is against their local security guidelines. Individuals have a personal responsibility to inform line managers and/or to take appropriate action themselves to address

Line Managers, Supervisors or Security Controllers

Line Managers, Supervisors and Security Controllers are expected to exercise a duty of care for all staff and to be mindful of the potential security risks associated with issues such as personal relationships, health, debt or bereavement at all levels of security clearance.

take responsibility to ensure your team regularly reviews whether appropriate security is being maintained across the area

raise concerns and ensure security is being discussed at appropriate boards

raise issues of concern through to senior management and local security officers as appropriat.

Line Managers, Supervisors or Security Controllers have concerns about any individual they should first speak with the member of staff/contractor in a timely manner and then highlight any residual concerns to local security teams and arrange for them to be recorded on the individual’s vetting or personnel file as set out in local policy.

Process for BPSS

While BPSS checks are not part of vetting all staff at all levels retain a responsibility to follow the security guidance and processes for their area and to be aware of their personal responsibilities.

As BPSS is a one off pre-employment process it cannot be withdrawn. However, if an individual is found to be associated with groups or acting in a way that could cause concern, the department/organisation may choose to take actions to restrict or monitor that individual more closely.

General advice to Line Managers, Supervisors or Security Controllers


make sure the individual you are assessing understands the necessity of the questions on the form or being raised in discussion

ask difficult questions where there is cause to do so. If an individual refuses to discuss an area of concern with you, this should be recorded

offer the individual access to welfare/HR/Occupational Health if appropriate and as available in your department/organisation.

challenge negative or disruptive behaviours as this is part of good performance management as well as security management

offer support and work collaboratively with security and HR to address issues at the earliest point

Do not

make a recommendation on the basis of moral or ethical judgements (explicit or implied) about anything you are told – remember the context is how trustworthy the person is in their professional role

pursue a point for curiosity or to illicit unnecessary information. Discussion should focus on the behaviour and performance of the individual and how it affects their suitability to continue to hold clearance

make assumptions - gather evidence

modify your assessment because an individual or other party is unhappy - the ASAF is about the evidence and your assessment of it

Aftercare Incident Report (AIR)

AIRs should be raised by local security officers in cases where actual or potential security concerns exist about an individual who holds a security clearance.

If information become available that raises doubts about an individual’s suitability for access to protectively marked or sensitive assets the circumstances should be reported to us.

Notifications of this nature should be made via the NSVS portal please select the AIR option.

Financial questionnaire

A financial questionnaire is used to determine your financial circumstances, either as part of the initial security vetting process, or as part of the aftercare monitoring work which confirms your continued suitability to hold a security clearance.

Subject Access Requests (SAR)

You are entitled to apply under Data Protection Act 1998 to see the personal data held on you by us. This should be done by submitting a subject access request to us.

On receipt of a properly completed identified SAR, we will have 40 calendar days to reply.

Some data may be supplied in redacted (edited) form or withheld in accordance with the provisions of the Act, especially where it is supplied by a third party or falls under a national security exemption.



eforms are available over the RLI (MOD restricted network), GSi (government restricted network) and internet. They provide both flexibility and help prompts for completing the vetting application online, thus improving the ease and speed of completion. The completed forms are then uploaded directly into the NSVS case management system.

eform applications are instigated by a sponsor on an agreed network (RLI, GSi or internet). Upon account creation by the sponsor the subject is automatically emailed a unique link to the relevant eform portal to complete the application.

There are many advantages of using an eform including help prompts and inbuilt business rules to minimise or eliminate errors. This means that the number of rejected forms and requests for further information will be minimal. Also, vetting subjects are directed to complete only the questions that are relevant to them. The forms are flexible and allow the application to be saved at any stage. Once completed it is submitted directly into NSVS.

The whole technical solution for the NSVS IT vetting system has been fully security accredited, which includes the assessment of security risks and how these are managed. This is from the completion of the security questionnaires online, through the RLI/GSi and Internet eform portals, to the back end case management system and database, which manage the workflow of the vetting process and record the vetting information.

For people with no secure access, completion of an online security questionnaire will be done on the eform portal accessed through a secure site on the internet. This is the same type of set up that is used when you access your online banking. You will notice that the web address line turns green in the web browser and displays a padlock which shows that the eform is operating through a secure site albeit on the internet.

Initial access to the eform portal is achieved only through a unique link which is sent to your chosen email address either automatically through your sponsor or through our enquiry centre’s account creation process. This link is unique to your application and directs you to the eform portal where access is controlled by a thorough personal authentication process to verify identity, from which you are mandated to create your own login details that remain known only to you to enable subsequent access.

Providing information about vetting subjects

If you have been named as a supervisor or character referee for someone who requires a NSV clearance, you may be asked to provide information about that person. This will be in the form of an interview with a Vetting Officer or by a written testimony form. As with data supplied by the vetting subject, this will not be passed outside the security community except in exceptional circumstances, and will not be supplied to the vetting subject without your express permission.

If you work outside the Government email network and receive a written testimony form as an email attachment, you will see the following notice:

You may choose to return your response by email or in hard copy to the address shown on the form: a reply paid envelope can be provided on request. Please be aware that if your response contains sensitive personal data email is not a secure method of transmission unless sent from a government network.

It is not possible to define “sensitive” personal data, although you may feel this applies to data which is clearly private and which the vetting subject would not wish to be widely known. If you require further advice or to discuss the type of information you are providing and how it may be transmitted, please contact the NSV Data Protection Officer.

Requests for ‘security certificate’ for employment purposes

You should note that although the record of security decisions are kept by us, the formal notifications of clearance announcing decisions are sent only to the vetting sponsor. You are not sent a copy of the notification of clearance, primarily for security reasons: the notification represents a vetting decision made on the day of issue, and clearance may have been lapsed or withdrawn at any time since that date.

If at any time you need to know your vetting status for employment reasons, the sponsor or prospective sponsor should contact the DBS NSV enquiry centre. We will release a copy of a Notification of Clearance in response to a SAR that specifically requests this, but it will be amended to show that this does not necessarily represent current vetting status. The following wording appears on all current Notifications:

This notification of clearance refers to the employment and sponsor for which it was raised. It may be transferable: refer to appropriate security regulations (SPF/ JSP 440) for details. Please note that a clearance may be withdrawn or may otherwise have its status changed at any time before its expiry date. To confirm that this clearance remains valid, you should (if you hold a sponsor / vetting status information (VSI) account) use the NSVS VSI facility. If you do not hold such an account contact the DBS NSV enquiry centre (01904 662644) to check the status of the clearance.

There should therefore be no reason for vetting subjects to request a copy of their notification of clearance for employment reasons.

Registering as a sponsor

It is a requirement that all sponsors are registered before they can submit an eform or hard copy NSV applications. Therefore if you need to sponsor an application or have a requirement to frequently enquire about the vetting status of a subject (i.e. whether they have a valid NSV clearance) through the vetting status information facility but do not have a sponsor account then you will need to follow the guidance below.

Any NSV applications received without a sponsor account will be returned to source because the new tighter security measures require full registration of sponsors. Once you have registered, you will need to provide your unique identifier when making any future enquiries to the DBS NSV enquiry centre, telephone 01904 662644.

You will need to contact your departmental security authority (DSA) to discuss your requirement to act as a sponsor for NSV applications or to have access to a VSI account. If the DSA agrees to the request they will send you a registration form and guidance notes to complete and return to them. Should the DSA not approve the request they will inform you of the reason for the denial.

The DSA will check the registration form and sanction the requested account(s) and forward this information to us for an account to be created in NSVS. Please note that in no circumstances should the sponsor send their completed registration form directly to us, the DSA must first authorise all sponsor account requests.

The account will normally take 2 working days to process and once complete the NSVS system will automatically notify the sponsor by email on how to verify and action their account. The system will also automatically send the new sponsor their unique sponsor ID by email. This unique ID must be entered on all eforms and hardcopy NSV applications. Our enquiry centre advisors will also request this unique ID from all callers before they confirm any vetting information.

Should the sponsor forget or misplace their unique sponsor ID they should contact the DBS NSV enquiry centre who will action the request to the customer accounts team, they will then respond to the request.

Further information on obtaining a sponsor account can be sought by contacting the relevant DSA for your business area.

Using the eform portal

Once a sponsor account has been created by us, a confirmation registration email is automatically generated and sent to the sponsor.

Decision Maker

Information for decision makers

There are an array of benefits to other government departments (OGDs) and Service Lead Commands (SLCs) gaining Case Management System (CMS) access to NSVS:

increased and targeted automation, coupled with improved cross agency interfaces, will result in a decrease in processing times for straightforward applications.

the quality of decision making will be enhanced as less time will be spent on clerical effort.

OGDs and SLCs will have real time access to vetting information on which to base their decision making.

Access to NSVS CMS is restricted to authorised users holding a valid security clearance of SC or above. This must be confirmed by the account requestor and will be verified by DBS prior to account creation. NSVS CMS users must immediately stop accessing any part of the system if their security clearance ceases to be valid and this fact must be reported immediately to the Vetting Authority and System Administrators.

This will ensure we can maintain our current level of confidence in the personnel security credentials of all NSVS CMS users as an extra level of assurance in the security and integrity of NSVS and the protection of its data.

If you require further information contact the DBS NSV enquiry centre.

Case Management System

The NSVS CMS is the main vetting system which manages and processes all vetting cases. It is available to designated MOD and OGD decision makers. The CMS is accessible through the RLI, PSN Protect (IL3) and PNN networks at Impact Level 3 (IL3). It allows decision makers visibility of all the information linked to a vetting case on which to base their clearance decision.

Referees and Hiring Managers


A referee should be someone who has known you well over a significant recent period of your life. We will ask them to describe you and your way of life away from work.

The Vetting Officer will double check the information given in the vetting questionnaire. Please make sure that the referees you have nominated are aware that you have nominated them and are willing to be interviewed. Please also advise them that they will not necessarily be contacted.

(Note: An information leaflet is issued to all referees who are to be interviewed). It would also be helpful if you could advise anyone else who we might contact, such as your current/previous senior officers/line managers or educational establishment, that you are undergoing vetting and have agreed to the process.

Please note that our enquiries will not be confined to past and present employers and nominated character referees.

Choosing a referee

We ask former employers, senior officers and educational establishments for information about you.

We also ask you to choose some people who have known you well for a significant recent period in your life, to act as referees. We hope that you will ask such people for permission first and make sure that they are willing to be interviewed.

We will not necessarily contact all Referees who have been nominated. Our enquiries will not be confined to past and present employers and nominated character referees.

Role of a referee

If we decide to use you as a referee, the Vetting Officer will question you to double check the details that the person being vetted has given us and those we have collected by carrying out other checks.

After you have received the referee’s information leaflet the initial contact will be by telephone. There may be some delay due to operational priorities and other factors, so please be patient. Interviews will usually be face to face but may occasionally be conducted by telephone.

If you have sensitive information to divulge or feel uncomfortable discussing the person being vetted over the telephone, a face to face interview will always be arranged.

Hiring Manager

If you wish to employ staff awaiting their clearance there is no central regulation prohibiting the employment of people awaiting the security clearance. The decision whether or not to do this, limiting access as necessary, is a risk management judgement for the area concerned and as advised by his or her security staff.

In making this judgement, the business manager must take into account the sensitivity of the business area, the information held, and local conditions of work and of the practicality of limiting access. If in doubt, Personnel Managers should deal with us directly. For a security clearance case contact the DBS NSV enquiry centre (01904 662644) to agree arrangements.

There is no requirement to re-vet staff that re-join within a year of leaving, other than in exceptional circumstances. Where a security clearance needs to be transferred the receiving personnel authority/company should phone the DBS NSV enquiry centre (01904 662644) at the outset to find out whether an individual holds a clearance and to initiate the transfer.

Contractors and Consultants

Guidance on security clearance for companies who bid for MOD contracts?

You do not need to hold security clearances to bid for MOD work advertised in the Official Journal of the European Community and other sources. The MOD contracting procedures make sure that there is no competitive advantage in having prior security clearances. Requests for clearances must be raised during the contractual process.

Advertising for staff that already hold a security clearance is contrary to government policy, unnecessary and potentially discriminatory, as laid out in the Cabinet Office code of practice document, “Recruiting for vacancies requiring National Security Vetting Clearance.” Any individual who sees such a criterion specified in advertisements when seeking employment can inform the Cabinet Office by forwarding full details of the post and the employer to the following email address: vettinggroup@cabinet-office.x.gsi.gov.uk.
