UK Security Vetting (UKSV)
UK Security Vetting (UKSV)
What is Vetting?
UK Security Vetting (UKSC) helps employers and employees identify, manage, and mitigate risks for roles involving national security considerations, such as access to sensitive sites, classified information, or secure systems. It establishes trust between employers and employees through a confidential, ongoing dialogue about managing risks for as long as a person holds security clearance.
Who delivers UKSV?
This is delivered by United Kingdom Security Vetting (UKSV), which is part of the Cabinet Office Government Security Group and the Government Security Function. UKSV staff are professional and culturally sensitive, treating all applicants with respect throughout the process.
What information will I be asked for?
Anyone, irrespective of background or circumstance, should feel able to apply for a security clearance. Information is gathered in a proportionate, respectful, and sensitive way. You may be asked to provide information about your:
Background, family, and employment history
Places of residence
Criminal convictions
Financial situation (for higher clearance levels)
Personal life experiences
Why will I be asked for this information?
There are no right or wrong answers. The process makes no judgements about you as an individual. Information is only requested to identify areas of risk relevant to the clearance level required. Depending on your clearance level, we may need to understand:
Nationality and overseas connections - particularly connections to countries with which the UK has more challenging relationships
Financial circumstances - whether your spending is sustainable, recognising most people manage debts and credit agreements
Health and wellbeing - only where strictly relevant to risk management; health considerations rarely cause concern
Personal matters - in strict confidence, only to understand if there is a risk of information being used against you maliciously
Relationships and associations - to understand if any significant influences could present inappropriate risks
Online presence - for civil and crown servants, whether public online content is consistent with the Civil Service Code.
Clearance levels
Security Check (SC) Clearance
All new MDP entrants must obtain SC clearance as a minimum requirement. SC clearance involves credit checks and checks against UK criminal and security records, including overseas records where appropriate.
Read the SC guidance pack for applicants.
Developed Vetting (DV) Clearance
Postings to sites such as the AWE require the enhanced DV clearance level. DV checks include:
Completion of detailed security questionnaires
Financial checks including Credit Reference Agency checks
Telephone or in-person interviews with character referees
A detailed interview conducted by a Vetting Officer
DV clearance ensures your character, personal circumstances, and integrity mean you can be trusted with access to sensitive information and assets. Even if not initially posted to a DV clearance site, you will need to obtain DV clearance if later posted to a site with higher security requirements.
Read the DV guidance pack for applicants.

Frequently asked questions
What will happen if my first posting is to a site where enhanced security clearance is required, and I fail to obtain this level of clearance?
You would be offered an alternative posting at a site appropriate to the clearance level that you achieved prior to appointment. There would be no entitlement to relocation expenses. You are therefore advised that you should not commit financially to a move of home, until it is confirmed that you have the required standard of clearance for your designated posting.
