What Is BPSS Clearance for Contractors? | Definition
Last updated: 20 October 2026
BPSS (Baseline Personnel Security Standard) clearance for contractors is a pre-employment screening check — identity, right to work, employment history and a basic criminal record check — required before someone can access UK government premises, data or sensitive contracts. It is the minimum vetting level across central government and much of the wider public sector supply chain.
Key Takeaways
- Priority First notes that BPSS stands for Baseline Personnel Security Standard, the UK government's minimum pre-employment vetting check for contractors and staff.
- BPSS replaced its predecessor, the Basic Check, in 2006, according to Security Watchdog (2018).
- The current BPSS policy was updated in June 2026 and published on 28 July 2026 as Version 7.0, per GOV.UK / Cabinet Office (2026).
- BPSS checks typically take 3-5 working days for standard UK-based employees through a modern digital process, per Checkback (2026).
- BPSS requires confirmation of at least three years of employment history, with any gap of 6 months or more spent overseas declared, per GOV.UK Baseline Personnel Security Standard Policy / Credence (2026).
What BPSS clearance means in practice
BPSS clearance means a contractor has passed four core checks before starting work: identity verification, right to work in the UK, a basic (unspotted) criminal record check, and confirmation of employment history. For contractors working on government buildings, public sector facilities management contracts, or sites handling official data, BPSS is usually the entry threshold — sitting beneath higher tiers such as Counter Terrorist Check (CTC) and Security Check (SC), the latter formally reviewed at least every 10 years, or every 7 years for some non-Facility-Security-Clearance contractors, according to Careers in Defence (2026). Priority First, which protects commercial and residential sites across prime central London and nationwide, treats this level of identity and background assurance as a baseline expectation for personnel deployed to client sites, alongside its own operational screening standards. That same emphasis on verifiable assurance runs through Priority First's patrol work: across its largest portfolio, Priority First has completed 4,900+ photo-backed patrols, each carrying officer ID, GPS and timestamp — the same instinct for provable, attributable records that underpins BPSS-level vetting of the people carrying out the work. On individual sites, this extends down to checkpoint level, where Priority First took one mixed-use development from zero photographed checkpoints to 152.
