Slip testing
in Colchester.

Why Colchester needs real PTV data.

Colchester's mixed commercial base — garrison, higher education and retail — means slip risk is spread across retail, offices, civic buildings and leisure venues in equal measure. Any estate of more than a handful of sites benefits from a portfolio-wide testing programme rather than reactive post-incident work.

A typical Colchester portfolio survey covers 8–15 sites in a rolling programme, with consolidated reporting that highlights which sites need intervention first.

Pendulum testing. Not opinion.

The pendulum method — defined in BS 7976 and BS EN 16165, and referenced throughout HSE guidance — is the only test HSE considers reliable on wet or contaminated floors. A rubber slider swings from a fixed height and drags across the test surface; energy lost to friction is recorded as a Pendulum Test Value (PTV) on a scale of 0 to 150.

HSE classifies any PTV below 25 as a high slip potential. 25–35 is moderate. A PTV of 36 or above, measured wet and dry with the correct reference slider, is the benchmark for a floor considered safe under normal use. Every report we produce in Colchester is issued under our UKAS ISO/IEC 17025 accreditation — the method, the technician and the equipment are all independently audited.
