About Pendulum Slip Testing

A specialist UKAS ISO/IEC 17025 accredited pendulum slip resistance testing service, operated by Surface Performance Ltd.

Who we are

Pendulum Slip Testing is the dedicated pendulum testing service of Surface Performance Ltd, a UK testing and consultancy laboratory. Surface Performance holds UKAS ISO/IEC 17025 accreditation specifically for slip resistance testing, alongside accreditations for sports surface testing under FA, FIFA, World Rugby, FIH and ITF protocols.

This site exists to make it simple to commission pendulum testing — whether the test is needed for compliance, litigation, insurance, or risk management — and to provide reference material that explains how the test method actually works.

What we do

We measure how slippery a floor is. The pendulum tester — a TRL-pattern instrument calibrated to BS EN 16165:2021 Annex C (formerly BS 7976-2, withdrawn February 2022) — produces a single number called the Pendulum Test Value (PTV) that quantifies the dynamic friction between a rubber slider and the floor surface, under both wet and dry conditions.

Our reports interpret that data against UK Health and Safety Executive (HSE) guidance, contractual specifications such as BS 8204, and where applicable the requirements of CPR Part 35 for civil litigation.

Why the test matters

Slip and trip accidents account for roughly a third of major workplace injuries in the UK. The pendulum is the only test method the HSE considers reliable for assessing wet-floor slip risk, and pendulum data is the most defensible evidence available for demonstrating — or challenging — whether a floor was reasonably safe at the material time of an accident.

For property owners and managers, periodic pendulum data forms part of the documentary evidence that reasonable practicable steps have been taken under the Health and Safety at Work Act 1974. For specifiers and main contractors, BS EN 16165 testing closes out new-build floor specifications under BS 8204.
