What is BS7858:2019 and who needs it?

BS7858:2019 is the British Standard for pre-employment screening of security personnel. It sets out the minimum requirements for employers to verify the integrity, reliability, and suitability of staff in safety-critical or sensitive roles.

Key roles which should adhere to the standard include the following:

  • Security guarding and door supervision
  • CCTV Operators
  • Close Protection Officers
  • Key holding and alarm response
  • Facilities management
  • Staff working within data-sensitive environments

Typical timeline and what to expect

The screening process usually takes 1–4 weeks, depending on:

  • Candidate responsiveness
  • Number of previous employment references
  • International checks for overseas history

We provide clear guidance and support to ensure the process runs smoothly and any delays are kept to a minimum. Our team helps candidates and employers prepare documentation in advance, reducing risk of failure and speeding up the process.

What employers misunderstand about BS7858

Even experienced organisations can sometimes make mistakes when it comes to BS7858 vetting. Understanding the most common pitfalls helps you avoid compliance issues and hiring risks.

  1. Treating BS7858 as optional

Some employers assume BS7858 is only ‘nice to have’. In reality it is often contractually required, particularly for security, facilities management, and critical infrastructure contracts. Skipping or underestimating it can result in lost business or audit failures.

  1. Assuming all checks are quick and simple

BS7858 screening involves detailed identity, employment, criminal, and integrity checks over a 5-year history. Many employers underestimate the time and effort required which leads to delays or incomplete vetting.

  1. Overlooking gaps or inconsistencies

Unverified gaps in employment, residence, or education are a common reason candidates fail BS7858 screening. Employers often fail to request proper documentation, leaving them exposed to risk.

  1. Handling screening in-house without expertise

Attempting BS7858 vetting internally without specialist knowledge can result in:

  • Missing critical reference checks
  • Mishandling sensitive data
  • Delays in compliance reporting

Professional vetting providers ensure every check meets the standard, saving time and reducing risk.

BS7858 screening isn’t just a tick-box exercise but a rigorous standard designed to protect your organisation. Avoiding these common mistakes ensures your hiring decisions are secure, compliant, and reliable.

 

Frequently Asked Questions

Typically 1–4 weeks, depending on candidate responsiveness, employment history and whether overseas checks are required.

BS7858 requires screening to be current and role-specific, so previous checks may not always be valid.

Gaps must be fully explained and supported by evidence (for example: travel records, and benefit statements).

Employers receive a full report confirming whether candidates meet the BS7858 standard.

The standard does not mandate periodic re-screening however this should be determined on role risk. If an applicant leaves and re-joins employment, their screening should be brought back up to date and any gaps accounted for.
