Pendulum testing
across Wiltshire.

Why Wiltshire needs real PTV data.

Wiltshire's mixed commercial base 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.

Large distribution estate at Swindon, substantial defence sector across the plain, and heritage tourism at Salisbury.

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 for exactly 127mm; 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 Wiltshire is issued under our UKAS ISO/IEC 17025 accreditation (Lab 7933) — the method, the technician and the equipment are all independently audited.
