BS 8204 is the British Standard governing screeds, bases and in-situ floorings. Where slip resistance is referenced — typically PTV 36+ wet — independent pendulum testing under our UKAS accreditation provides the evidence main contractors and clients need to sign off the floor at handover. Without this evidence, the contractor has no defensible record that the floor meets the contract.
Many BS 8204-referenced specifications now include slip resistance as a performance requirement. But verification at handover is frequently absent or perfunctory — a manufacturer datasheet does not constitute in-situ verification of the actual installed surface. If a slip claim arises in the building's first years of occupation and the floor is found to be below specification, the absence of independent handover testing leaves the contractor exposed.
BS 8204 testing is typically scheduled in the final week before practical completion, after final cleans and before snagging closes. Where the floor is being installed in phases (e.g. a multi-floor commercial fit-out), we attend multiple times during the build to test each phase as it completes — avoiding a single end-of-project bottleneck and giving the contractor early warning of any zones that need remedial action.
Where testing identifies a non-compliant zone, the typical remedial pathway is: chemical anti-slip treatment for polished porcelain or natural stone; mechanical re-finishing for resin and concrete; replacement for vinyl and tile where treatment is not viable. We re-test after remedial works under the same UKAS methodology so the handover file shows both the original test and the verified remediation.
We routinely work with major UK construction contractors, fitting test visits around handover programme constraints. Where building control is also requiring slip-resistance verification, our UKAS-accredited report meets that requirement directly.
