A complete guide to BS7858 standards and screening in 2026

BS7858 employee screening is a structured process for checking people who will work in secure or sensitive environments. It examines identity, employment history, criminal records and other relevant information so employers can make a documented decision about whether someone is suitable for the role.

What is BS7858?

BS7858 is the British Standard for screening individuals who work in secure environments. The current standard is BS 7858:2019, titled Screening of individuals working in a secure environment. Code of practice.

A secure environment is any workplace where an employee could compromise people, property, data or other valuable assets. This includes physical security roles and positions involving access to confidential systems, restricted sites or sensitive information.

BS7858 gives employers a consistent screening framework. It helps them collect enough verified information to assess a candidate’s honesty, identity and employment history before granting access to sensitive areas or responsibilities.

Is BS7858 a legal requirement?

BS7858 is a code of practice rather than a law. Many organisations still need to follow it because of contractual, regulatory or accreditation requirements.

For example, Security Industry Authority Approved Contractor Scheme members must follow the relevant British Standards, including BS7858 for pre-employment screening. Clients may also make compliance a condition of a security contract.

Employers should check their contracts, industry rules and accreditation conditions before deciding whether the standard applies. Following BS7858 can also provide evidence that the organisation has used a recognised process to assess personnel risk.

Which employees should receive BS7858 screening?

The standard applies to people working in roles where misconduct could threaten security or safety.

Common examples include:

• Security officers and control-room staff
• CCTV operators
• Employees working in data centres
• Facilities and maintenance staff with unrestricted site access
• Workers handling confidential information
• Employees responsible for valuable goods
• Contractors entering restricted locations

The scope extends beyond conventional security companies. Financial services, healthcare, logistics, technology and critical infrastructure businesses may use the standard when staff have privileged access.

Employers should assess the role itself rather than relying only on its job title.

What checks are included in BS7858 employee screening?

The exact screening package depends on the role and the information available. A typical process includes confirmation of identity, address history and the individual’s right to work.

It also examines employment, education and other activity over the required screening period. Employers must investigate unexplained gaps and check that the candidate’s account is consistent with supporting evidence.

Criminal record screening may be required, although the employer must request the correct level of Disclosure and Barring Service check for the role. Most employers can request only a basic check. Standard and enhanced checks are restricted to eligible positions.

Organisations may also consider financial information, directorships or sanctions screening when the role creates a relevant risk. These additional checks must be lawful, proportionate and clearly connected to the position.

Veremark provides a dedicated BS7858 security screening service that combines the checks needed to screen towards the standard.

How much employment history must be checked?

BS7858 screening generally examines a candidate’s continuous career and activity history over the previous five years, or from the end of compulsory education when that period is shorter.

The history may include employment, self-employment, education, unemployment and extended travel. Employers need a clear account of what the individual was doing throughout the relevant period.

An employment history check can confirm details such as job title, employment dates and previous employer information. Any discrepancy should be reviewed rather than automatically treated as proof of dishonesty.

How are gaps in employment handled?

Gaps of 31 days or more should be explained and supported with suitable evidence.

A gap may have a reasonable cause, such as job seeking, caring responsibilities, illness or travel. The purpose of the check is to establish a credible record of the person’s activity during that time.

Evidence could include government correspondence, travel records, benefit documentation or another reliable record. Where documentary evidence is unavailable, the employer may need an alternative form of verification permitted by its screening procedure.

Unexplained gaps often delay screening because they prevent the employer from establishing a continuous history.

Does BS7858 require a criminal record check?

Criminal record information forms part of the assessment, but employers must follow the law governing DBS checks and spent convictions.

A basic DBS check may be requested for any role and shows unspent convictions and conditional cautions. Standard and enhanced checks are available only when the position meets statutory eligibility rules.

A conviction should not trigger an automatic rejection. Employers should consider its relevance, seriousness, age and relationship to the duties of the job. Veremark’s criminal record check service supports checks at the appropriate level for the position.

Does BS7858 replace a right to work check?

No. Employers must still conduct a valid right to work check before employment begins.

The right to work process confirms whether the person has permission to work in the UK. BS7858 addresses wider suitability and security concerns. Completing one does not satisfy the requirements of the other.

Employers can use a right to work check alongside BS7858 screening to keep the two decisions properly documented.

Can someone start work before screening is complete?

The standard allows conditional employment in certain circumstances, provided the organisation has completed the necessary preliminary checks and manages the risk.

The employer should define what access the person may have while screening remains incomplete. Restrictions could include supervised work, limited system permissions or exclusion from sensitive areas.

Conditional employment should have a clear end point. Outstanding checks must continue promptly, and the final decision should be recorded once all relevant information has been reviewed.

How long does BS7858 screening take?

The timescale depends heavily on the candidate’s history and the speed of third-party responses.

A straightforward case may progress quickly when the candidate provides accurate information and former employers respond promptly. International employment, missing documents and unexplained gaps can extend the process.

Employers can reduce delays by telling candidates what evidence is required at the start. A structured digital process also makes it easier to track outstanding checks and follow up with referees.

Can a candidate fail BS7858 screening?

BS7858 does not create a universal pass or fail result. It gives the employer a process for gathering information and reaching a reasoned decision.

A discrepancy does not always make someone unsuitable. Dates may be remembered incorrectly, employers may hold incomplete records and names may have changed. The screening team should give the candidate a fair opportunity to explain material findings.

The final decision should reflect the risks of the specific role. Employers should use written criteria so similar cases receive consistent treatment.

What records should employers retain?

Employers should retain enough information to show what checks were completed, what evidence was reviewed and who approved the decision.

Screening data contains personal and sometimes sensitive information. It should be stored securely, accessed only by authorised staff and kept no longer than necessary. Employers must also provide appropriate privacy information and identify a lawful basis for processing under UK data protection law.

The screening record should be clear enough for an auditor or client to understand how the decision was reached.

How should employers manage BS7858 screening?

A sound process starts with a written policy that defines which roles require screening, which checks apply and how adverse findings will be assessed.

Candidates should receive clear instructions and requests for evidence early in the hiring process. Screening should then follow the same documented workflow for every comparable role.

Using a specialist background screening platform can reduce manual follow-up and keep evidence in one controlled system. Responsibility for the hiring decision still remains with the employer.

What is the main benefit of BS7858 employee screening?

BS7858 employee screening gives employers a recognised method for assessing people who will hold sensitive access or security responsibilities.

Its value comes from consistency. The employer can show that identity, career history and relevant risk information were checked before trust was granted. That creates a stronger basis for hiring decisions and a clear record when clients, regulators or auditors ask how staff were screened.
