BS7858 Security Screening


BS7858 screening is the best practice procedure published by the British Standards Institution. It is the background screening (vetting) of individuals employed in an environment where the security and safety of people, goods or property is a requirement of the employing organisation’s operations and/or where such security screening is in the public and/or corporate interest.

BS7858 screening includes:

  • 5 or 10 Year Written Career History
  • Basic Criminality Check
  • Credit Search (Consumer Information Check)
  • ID Verification and Right to Work Check
  • 5-Year Address Verification

Implementing BS7858:2019

As of 31st March 2020, we fully implemented the new BS7858:2019 Screening Standard for all Applicants. The BS7858 code of practice has been revised and several important changes have been made, including the removal of character references. The BS7858 standard now places a much stronger emphasis on Applicants to supply documentation to verify each period of their career history at the start of the process, as well as several other changes. If you would like to speak to our team about the changes, or have any questions, please email and we will respond as quickly as possible.


BS7858 screening is more comprehensive than other UK standard screenings. It involves a more rigorous process to ensure employers have a peace of mind that the people they are employing are trustworthy.

Our team have extensive knowledge and experience with BS7858 screening. They will provide a comprehensive service to ensure appropriate screening is completed while maintaining the quality and robustness of the checks.


Although BS7858 originates from the security industry, screening employees to BS7858 is widely used throughout the UK and overseas within the Finance, Insurance, Banking, Healthcare, Aviation, Education, HR, Facilities Management and IT Industries to mention but a few. In principle, any organisation can have their employees and volunteers screened to BS7858 to improve the quality of their service, or comply with regulation, compliance standards or laws that require a higher level of due diligence.

These are the steps of a typical BS7858 screening check:

  1. The “Sponsor” (our Client) creates an application and the applicant receives an email inviting them to complete the application form.
  2. The Applicant completes the application and submits it, with their consent, to the Client for review.
  3. The Client checks and submits it to Staff Vetting – the Client must check the Applicant’s consent, documents and information are valid before submitting it to us.
  4. Input & Verification – we check the applicant has provided valid consent and enough accurate data and documents for us to be able to carry out the next step.
  5. Pre-Employment Checks (if applicable):
    • Initial Checks + DBS – we carry out an ID check, Credit check, apply for the DBS certificate and verify that the applicant has provided us with 2 documents for each period of employment for the most recent three years of their Career History: 1 covering the beginning and 1 covering the end. References are not usually sought from previous employers at this point. We will contact the Applicant directly if we need them to clarify anything, or if they need to provide more documents or alternative evidence.
    • Acceptable documents include: NI records*, payslips, a contract of employment, formal correspondence with an employer, P45 or P60, bank statements, accountant’s statements, invoices, self-assessment tax returns, educational qualifications or certificates, passport stamps, travel or accommodation receipts.
  6. 5-year Career History – this is where we contact the previous employers the Applicant has listed in their Career History and ask them to provide a reference. After receiving a reference, we check the dates match and look for any gaps and follow up with applicant if necessary. If we don’t receive a reference, we will ask the Applicant to provide two supporting documents for each period in question. To verify any periods of employment or career history for the last three years, we can no longer ask for personal references for any kind of BS7858. Here is a list of documents we can accept as proof for each period of Career History.
  7. QA – this is where we review the entire application and check it meets the Standard’s requirements.
  8. Reporting (to the Sponsor/Client) – this is where we report the outcome to the client.
