BS7858 vetting is the British Standard for screening individuals in security environments. For most UK security operations — whether in-house or contracted — it is not a quality initiative or a best-practice aspiration. It is a contractual requirement, frequently a legal requirement and in some sectors a regulatory obligation.
Yet the majority of security recruitment processes still begin vetting after an offer has been made. Candidates are screened weeks after hire, operations are disrupted while placements are pending and employers carry the risk of individuals working in sensitive environments before their background has been verified.
This is not a process problem. It is an information problem. And it is solvable.
What BS7858 Actually Requires
British Standard BS7858 specifies the minimum screening requirements for individuals working in security environments. The current edition is BS 7858:2019+A1:2023, published by the British Standards Institution.
A compliant BS7858 screen must include:
- Identity verification: Passport, national identity card or birth certificate with secondary photo ID
- Right to work check: Legal requirement under the Immigration, Asylum and Nationality Act 2006 — must be completed before the first day of work
- 5-year employment history: Every employer for the preceding five years, with no unexplained gaps. Gaps must be explained and verified. References must be obtained from each employer.
- 5-year address history: Every address for the preceding five years, verified where possible
- Criminal record disclosure: DBS check at the appropriate level for the role
- Financial checks: Credit reference check at the level appropriate for the role
Right to work is not part of BS7858 — it is a separate legal obligation. You must complete a right to work check for every employee before they start work, regardless of whether BS7858 vetting is required. Failure to do so carries fines of up to £60,000 per illegal worker. Use the Home Office online checking service for share code verifications.
Who BS7858 Applies To
BS7858 applies to individuals employed in security environments where they have unsupervised access to people, property or information. In practice, this covers virtually all front-line security roles in the UK:
- Door supervisors and event security
- Static guards at commercial and residential premises
- CCTV operators and control room staff
- Close protection officers
- Key holding and mobile patrol officers
- Security managers and supervisors
- In-house security teams at retail, corporate and healthcare environments
If your contract with a client specifies BS7858 compliance — and most professional security contracts do — then you are legally exposed if you deploy unvetted staff, regardless of whether vetting is complete.
The Gap Between Offer and Clearance
The standard timeline for a BS7858 screen run from scratch is 2 to 6 weeks. The most common causes of delay are:
- Incomplete employment history — the candidate cannot name employers or provide dates accurately
- Missing reference contacts — no direct HR or management contact for previous employers
- Unverifiable gaps — periods of unemployment or self-employment that cannot be substantiated
- Address history gaps — candidate does not remember all addresses for the preceding five years
- Slow employer responses — references take weeks rather than days
All of these delays are information problems. They occur because the information required was not collected at application stage.
How UKSecurityJobs Solves This
Every candidate on UKSecurityJobs completes a BS7858-ready profile before they can apply for a single role. This means:
- Five-year employment history with employer addresses, reference names, direct phone numbers and email addresses for each
- Five-year address history with exact move-in and move-out dates
- Right to work status declared — UK citizen, ILR, visa type and expiry date
- SIA licence verified against the public register
When a candidate applies for a role through UKSecurityJobs, you receive a structured profile containing the information your vetting team needs to begin a BS7858 screen — employment history, address history, reference contacts and right to work status are already collected and verified. The DBS check and any remaining vetting steps are yours to run, but the groundwork is done.

What to Do When Vetting Reveals Issues
BS7858 screening will occasionally reveal information that requires a decision — a criminal conviction, an unexplained gap, a negative reference. The standard does not automatically disqualify individuals with criminal records. Each case must be assessed on its merits, considering the nature of the conviction, its relevance to the role and how long ago it occurred.
The SIA publishes guidance on which convictions disqualify individuals from holding an SIA licence. For roles that do not require an SIA licence but still require BS7858 vetting, your organisation's own policies and any client contractual requirements will apply.
Document your decision-making process. If you deploy an individual after discovering information during vetting, record why you made that decision and who authorised it.
