What is BPSS?
The UK Government’s baseline screening standard
BPSS is a series of pre-employment checks designed to provide a consistent baseline of assurance before someone works within or for government. Its purpose is to help organisations confirm entitlement to employment, protect government estates and assets, and provide a basis for national security vetting where a role requires it.
The operational decision is wider than ordering four checks. The organisation must also understand who the person is, why they require access, which role, supplier, site or project they belong to, whether the evidence is complete and whether it meets policy.
Who needs BPSS?
BPSS applies to people working within or for government where the standard is required for access to government assets.
-
Civil Servant
-
Members of the armed forces
-
Temporary Staff
-
Government contractors
-
Supplier personnel
The employing authority determines which roles require BPSS and remains responsible for ensuring the standard is applied.
BPSS requirements
What checks are included in BPSS?
UK Government guidance defines BPSS around four main checks. They work together as one baseline standard; none should be treated as a substitute for the others.
01
Identity
Establish that the individual is who they claim to be. Acceptable evidence must be examined and discrepancies resolved; collecting a document alone is not the same as verifying identity.
03
Employment history
Corroborate previous employment and review significant gaps, omissions or potential conflicts. Organisations may apply additional screening according to the role and risk.
02
Right to work in the UK
Confirm that the individual is legally entitled to perform the work in the UK using the applicable Home Office process. This remains a distinct legal responsibility for the employer.
04
Criminal record
Complete an unspent criminal-record check through the relevant authority for England and Wales, Scotland or Northern Ireland. This is one component of BPSS—not the whole standard.
BPSS is a pre-employment screening standard; it is not national security vetting or a formal security clearance.
The process
How does the BPSS process work?
A controlled process makes it clear what is complete, what is missing, who owns the next action and which role, supplier, site or project the person belongs to.
01
Confirm the role and requirement
The employing authority identifies that BPSS applies and defines responsibilities with any supplier supporting the process.
02
Invite the individual
The candidate receives a clear route to provide the information, evidence and consent required for the checks.
03
Complete the four checks
Identity, right to work, employment history and criminal-record evidence are gathered and verified.
04
Resolve gaps or discrepancies
Missing, adverse or inconsistent information is reviewed against the organisation’s policy and risk threshold.
05
Record the decision
The employing authority confirms the outcome and retains the evidence or verification record required for assurance and audit.
Contractors and supply chains
BPSS gets harder when the workforce is fragmented
A central security team may receive applications from many suppliers using different forms, providers and evidence formats. The challenge is connecting each result to the right person, employer, sponsor, site, project and access requirement.
A structured Clearance Application gives suppliers one submission route and gives the client a consistent record to review—even when supporting checks come from different providers.
