Current identity documents, nationality details, citizenship and immigration status where applicable.
Security Check (SC)
A practical guide for Advanced Engineering Group employees and subcontractors who may need access to security-sensitive projects, information or sites.
01 / UNDERSTAND
Security Check is national security vetting for roles involving long-term, frequent and uncontrolled access to SECRET assets, or occasional supervised access to TOP SECRET assets. It supports a risk-based decision—it is not a qualification, employment guarantee or personal possession.
02 / THE PROCESS
Do not begin independently. Your Advanced Engineering Group contact or contracting authority will tell you when a role requires vetting and who will sponsor it.
The contract authority confirms that the role requires SC and an authorised sponsor initiates the case.
Identity, nationality and immigration status, employment history and unspent criminal-record checks are verified.
You provide complete, accurate personal information by the deadline. The completed forms must then be checked by the contractor and sent through the correct approved secure route by authorised personnel.
Checks may cover departmental and criminal records, credit references and Security Service records. Follow-up questions or an interview may be required.
The sponsor receives the outcome. Do not assume clearance until formal confirmation is received.
For another authority or security-sensitive site, the receiving organisation validates the clearance and need-to-know. Site onboarding follows separately.
03 / PREPARE
Honesty, completeness and prompt replies matter more than trying to present a “perfect” history. Never omit information because you think it may cause concern.
BPSS requirement
A basic criminal-record check is required as part of the BPSS process before an SC application can progress. Use the service for the country where the role is based. Application fees apply and may change, so check the official service before applying.
Do not apply for the wrong check. Confirm the required route with Advanced Engineering Group or the authorised sponsor before paying. The correct service is normally determined by where the work will be carried out, not simply where the applicant lives.
Current identity documents, nationality details, citizenship and immigration status where applicable.
Accurate addresses and dates, including periods overseas. Check gaps and overlaps before submitting.
Employers, dates, roles and explanations for gaps. Include self-employment and unemployment periods.
Overseas residence, significant travel and relevant foreign connections requested by the questionnaire.
Information needed for credit checks. Explain financial difficulty truthfully rather than concealing it.
Up-to-date details for any people requested. Let them know they may be contacted.
Protect your information. Enter sensitive vetting data only in the official portal or an approved secure route. Do not send completed security questionnaires, passwords, bank data or full identity-document packs to a general email inbox.
03A / ONLINE QUESTIONNAIRE
The questions shown depend on the clearance level and your circumstances. Use this as a preparation guide, then follow the wording and help text in your own UKSV application.
Likely topic areas
UKSV says a Security Questionnaire can cover your background, family, employment and address history, criminal record and—in relevant cases—finances, health, overseas connections and other security information. Not every topic appears in every application.
Current and previous names, date and place of birth, nationalities held from birth, passport or naturalisation details, and relevant citizenship or immigration information.
Prepare for: “What nationalities have you held, and when?”
A continuous address history with month-and-year dates, including overseas periods. The form may ask about people who share living space with you.
Prepare for: “Where did you live during each period, with no gaps?”
Marital status, current partner and previous partners where requested, plus details of parents or guardians, siblings and—in some cases—your partner’s parents.
Prepare for: names, birth details, nationalities, occupations and current or last-known addresses.
Current employment and five years of employment history for an SC application, including self-employment, periods out of work, education and people or HR teams who can verify each period.
Prepare for: employer addresses, exact months, roles and any gap longer than three months.
If requested, suitable character referees with current direct contact details. Gather the level, sponsor or vetting organisation and approximate dates of any previous national security clearance.
Prepare for: people who know you well and can respond promptly.
Convictions, including spent convictions where the form requires them, charges and unresolved police matters. You may also be asked about previous clearance refusals, suspensions or withdrawals and other relevant security information.
Prepare for: dates, outcomes and a clear factual explanation.
If this section appears, expect questions about household income and outgoings, credit commitments, loans, mortgages or rent, properties, defaults, court judgments and shared financial responsibility.
Prepare for: balances, monthly payments and brief explanations of any difficulty.
The form may ask about overseas residence or connections, and only those health matters relevant to security risk. Use the additional-information field to explain estimates, missing details or unusual circumstances.
Prepare for: honest context rather than leaving unexplained gaps.
Before you start
Keep it offline and secure. Do not type personal or vetting information into this website.
Read the portal’s Preparation screen first. It reflects the form assigned to you and is the best guide to the exact information required.
Create continuous timelines. List addresses and employment month by month. UKSV advises that date ranges should meet without gaps; for SC, prepare five years of employment history.
Check names and dates against records. Use passports, naturalisation documents, address records, employment records and education dates. Record previous names exactly.
Confirm contact details. Check supervisors or HR contacts and tell any requested referees in advance. Use direct email addresses and mobile numbers where possible.
Review police and financial records if needed. If dates are unclear, official guidance suggests obtaining the relevant record or credit report rather than guessing without explanation.
Explain what you cannot obtain. Give as much as you safely can and use the form’s additional-information field. UKSV says not to put yourself at risk to obtain missing family information.
Work to the deadline and save as you go. Check every section for errors. Download or print your completed application before submitting because it cannot be edited or retrieved afterwards.
Watch for follow-up requests. Check every email address and phone number supplied. Respond promptly and use only the official portal or an approved secure document-upload route.
This is preparation guidance, not the questionnaire. Do not send names, dates of birth, addresses, family details, financial information, criminal-record information, portal credentials or completed answers to Advanced Engineering Group through this public page or ordinary email.

Tell the appropriate security contact promptly about relevant changes in personal circumstances, foreign travel or contacts, finances, criminal matters, or security concerns, as instructed.
Follow need-to-know, document handling, IT, photography, mobile-device and site security rules. Never discuss sensitive work casually or online.
Complete aftercare, reviews and renewal activity when requested. A clearance can lapse, expire, be restricted or be withdrawn.
Before moving between contracts or authorities, ask for clearance validation or a formal share/transfer. Never rely on an old pass or verbal assurance.
05 / CHECK YOUR CLEARANCE
A pass, old email or previous security-sensitive contract does not prove that an SC clearance is current or usable for a new role. Its status must be verified through the proper security channel.
Ask your current employer, contracting organisation or nominated security contact to check your clearance. Give them your full legal name, date of birth and any case or clearance reference you hold.
Your registered sponsor can request or check Vetting Status Information. UKSV states that this status information can only be discussed with registered sponsors who have an NSVS Sponsor account.
If you are moving to another security-sensitive contract or establishment, the receiving sponsor must confirm whether the clearance can be shared, transferred or otherwise accepted. Site access is approved separately.
Applicants and existing clearance holders can submit an enquiry through the UKSV Helpdesk web portal. Have your full legal name, date of birth, town of birth and Case ID, if known, ready for the security checks.
Do not share highly sensitive or personal information by ordinary email. UKSV advises using a secure file-sharing platform when such information is required.
06 / COMMON QUESTIONS
There is no guaranteed standard time. It varies with individual circumstances, the completeness of the form and checks required. Reply quickly to requests and do not make irreversible employment decisions until an outcome is confirmed.
Possibly, but it must be checked through the proper sponsor and receiving authority. A verified BPSS may also be required before a share or transfer is processed. Do not assume an existing clearance is active or accepted.
Declare it fully. Overseas residence may require additional evidence or enquiries; it is not, by itself, an automatic refusal.
Your sponsor or nominated security contact is the appropriate route. Managers and colleagues usually cannot see detailed vetting information.
Clearance may be awarded, awarded with aftercare, awarded with caveats or restrictions, refused, or voluntarily withdrawn. The sponsor will communicate the relevant outcome.
