When a business hires a security company, it is placing a high level of trust in the people protecting its premises, staff, information and assets.
Security officers may be given access to keys, alarm codes, restricted areas, CCTV systems and confidential information. For this reason, trust should never be based on assumptions alone.
It must be supported by proper background screening.
This is where BS 7858 vetting becomes essential.
What Is BS 7858?
BS 7858:2019 is the British Standard code of practice for screening individuals working in secure environments.
It provides a structured process for checking the identity, background and employment history of individuals before they are placed in positions of trust.
The standard is widely used throughout the UK private security industry and may apply to roles including:
- Security guards
- Door supervisors
- CCTV operators
- Mobile patrol officers
- Keyholding and alarm-response officers
- Close protection officers
- Control-room staff
- Security managers
- Other employees with access to sensitive areas or information
BS 7858 screening helps organisations make informed recruitment decisions and reduce the risk of unsuitable individuals being deployed.
What Does BS 7858 Screening Cover?
BS 7858 screening is much more than reviewing a CV or collecting one employment reference.
A professional screening process will normally include:
- Identity Verification – The candidate’s identity is checked using reliable documents and supporting evidence.
- Right-to-Work Check – The employer must confirm that the candidate has the legal right to work in the UK.
- Five-Year Career History – The candidate’s employment, education, self-employment and other activities are reviewed for the required screening period.
- Employment References – Previous employers or other suitable sources may be contacted to confirm dates of employment and relevant information.
- Employment Gaps – Any gaps in the candidate’s history must be explained and supported by appropriate evidence.
This may include periods of unemployment, travel, sickness, education or caring responsibilities.
Address History
The candidate’s address history is checked to support their identity and background information.
Financial and Public-Record Checks
Relevant public records may be reviewed for issues such as bankruptcy, insolvency or county court judgments.
Financial difficulties do not automatically prevent someone from working in security. Any concerns should be assessed fairly and in relation to the risks of the role.
Criminal-Record and SIA Licence Checks
Where appropriate and legally permitted, criminal-record checks may form part of the recruitment process.
For licensable security roles, employers should also confirm that the candidate holds the correct and valid SIA licence.
Overseas Checks
Additional evidence may be required where a candidate has lived, worked or studied outside the UK during the screening period.
Why Is BS 7858 Vetting Important?
Reducing Insider Threats
Security personnel may have access to high-value assets, confidential information and restricted areas.
Proper screening helps identify inconsistencies, unexplained gaps or other concerns before access is granted.
Although no screening process can remove every risk, it provides a structured way to reduce potential threats.
Protecting Clients and Employees
Inadequately screened personnel may create risks including:
- Theft
- Fraud
- Unauthorised access
- Data breaches
- Property damage
- Misconduct
- Reputational damage
BS 7858 screening demonstrates that reasonable checks were completed before an individual was placed in a trusted position.
Supporting SIA ACS Compliance
The Security Industry Authority’s Approved Contractor Scheme expects approved contractors to screen relevant personnel in accordance with BS 7858 or an appropriate industry equivalent.
Well-maintained screening files are therefore an important part of demonstrating professional standards and audit compliance.
Building Client Confidence
Clients increasingly expect security providers to demonstrate that their personnel are properly screened, licensed and trained.
A clear and complete vetting process gives clients greater confidence in the people protecting their business.
Protecting Your Reputation
A serious incident involving an inadequately screened employee can cause major reputational and financial damage.
Possible consequences include:
- Loss of contracts
- Failed audits
- Insurance disputes
- Legal claims
- Regulatory concerns
- Loss of client confidence
A documented screening process helps show that the organisation takes recruitment, compliance and security seriously.
Common BS 7858 Screening Problems
Security companies can experience audit findings when personnel files contain:
- Incomplete five-year histories
- Unexplained employment gaps
- Missing references
- Incorrect or conflicting dates
- Missing identity documents
- Inadequate right-to-work evidence
- Unverified reference contact details
- Missing overseas evidence
- Expired SIA licences
- Screening decisions that have not been signed off
BS 7858 should not be treated as a simple paperwork exercise. Every screening file should provide a clear and reliable record of how the candidate’s background was checked.
