Build UK Common Assessment Standard update: key compliance shifts for contractors
Reviewed by Joe Ashwell
First reported on The Construction Index
30 Second Briefing
Build UK has released the sixth update of its Common Assessment Standard, tightening Building Safety, Quality and Information Security requirements for the 26,000+ certified companies. Scaffolding and temporary works are now explicitly out of scope of Building Regulations unless they form part of the permanent structure, the Building Safety section has switched from ‘opt in’ to ‘opt out’, and competence questions have moved into a mandatory Quality section. Cyber Essentials Plus no longer grants exemption from Information Security questions, which now require ISO 27001, while fraud prevention, a named quality lead, and a Drugs and Alcohol Policy are compulsory for all suppliers.
Technical Brief
- Companies working under the Building Safety Act can use certification as evidence of organisational dutyholder capability.
- Opting out of the Building Safety section now requires a formal statement of non‑involvement in regulated work.
- Competence questions moved into Quality mean all suppliers must evidence competence, not just higher‑risk building projects.
- Information Security exemptions now tied solely to ISO 27001, tightening controls on project and client data handling.
- Data from one recognised assessment body can be shared at no cost with others, reducing duplicate safety pre‑qualification.
Our Take
Build UK appears in only a small subset of the 115 Policy stories in our database, but where it does feature it is usually setting de facto benchmarks for UK contractors, as with its cash retention benchmarking work alongside the Construction Leadership Council.
Having reached its sixth iteration since 2019, the Common Assessment Standard is evolving at a pace that means UK contractors and subcontractors now need to treat compliance as a live management process rather than a periodic prequalification exercise.
Because Build UK’s earlier benchmarks on cash retentions directly affected commercial terms in the United Kingdom supply chain, repeated updates to this safety-focused Common Assessment Standard are likely to carry similar weight in client prequalification and framework tendering decisions.
