Swimming Pool Slip Testing is a brand of Surface Performance Ltd, a UKAS ISO/IEC 17025 accredited testing laboratory. We deliver pendulum and surface roughness testing for swimming pools, hydrotherapy facilities, spa and thermal suites, changing rooms and aquatic leisure environments across the UK.
Surface Performance Ltd holds UKAS ISO/IEC 17025 accreditation for slip resistance testing. UKAS is the sole national accreditation body recognised by the British Government, and ISO/IEC 17025 is the international standard for the competence of testing and calibration laboratories. Our accreditation covers pendulum slip resistance testing under BS EN 16165:2021 Annex C (replacing the now-superseded BS 7976-2) and surface roughness Rz measurement.
What this actually means in practice: every pendulum reading we produce is traceable to national measurement standards through a documented chain of calibration; every test method we run is audited periodically by independent UKAS technical assessors; and every report is issued under quality-system controls that match the standard expected of a court-admissible expert.
Pool environments demand a different testing approach to general-purpose floors. Standard pendulum testing uses Slider 96 (Four-S rubber, simulating a shod heel). On wet pool surrounds where guests are barefoot, that slider gives misleading results — bare wet skin grips a wet surface differently to a rubber heel. Pool testing requires Slider 55 or Slider 57, the softer compounds that simulate bare wet skin.
Many UK testing providers run all environments with Slider 96. We don't, because the answer it gives in pool environments isn't the answer the duty-holder needs. Swimming Pool Slip Testing exists as a dedicated brand to make this distinction explicit and to make it easy for pool operators, leisure trusts, hotel groups and their advisers to find the testing approach that matches their environment.
We deliver two complementary UKAS-accredited methods:
Hotel groups, leisure trusts, local authorities, schools and academies, NHS Trusts, private clubs, insurance loss adjusters, panel solicitors (claimant and defendant), main contractors, M&E consultancies and architectural practices. The instructions span pre-handover compliance, periodic insurer-driven programmes, post-incident forensic work, expert witness reporting, pre-acquisition due diligence and anti-slip treatment verification.
Most instructions begin with the form on our contact page. Tell us the site address, the reason for testing, the approximate area, and any deadline. We come back with a quote within one working day. For urgent post-incident or pre-handover work, ring us on 0208 246 5562.
