Slip Testing FAQs: Your Pendulum Safety Questions Answered

The pendulum test simulates a heel striking the floor and measures the energy lost through friction. The resulting Pendulum Test Value, or PTV, indicates slip potential; a score above 36 is classed as low risk under UK Health and Safety Executive guidance.

During our survey we gather multiple readings across each traffic lane in both dry and wet states, then calculate the mean PTV. Scores below 24 denote high risk, 25–35 moderate, and anything 36 or higher meets HSE safety expectations.

All measurements are carried out by IOSH-trained technicians using UKSRG-calibrated equipment, so your evidence is defensible in court and instantly recognisable to insurers. Certified PTV testing avoids ambiguity, demonstrating you have taken all reasonably practicable steps to manage slip hazards.

Our pendulum device evaluates virtually any hard surface: ceramic tiles, vinyl, terrazzo, concrete, metal, natural stone and coated timber. Internal corridors, external walkways, ramps, pool surrounds and entrance mats can all be included within the same visit for clear comparison.

If any area returns a medium or high risk rating, we outline tailored control measures such as deep cleaning regimes, anti-slip treatments, matting, or signage. Follow-up testing can verify improvements and demonstrate your ongoing commitment to staff, patient or visitor safety.

The HSE recommends reviewing slip resistance whenever floor conditions, cleaning products or footfall change significantly. In practice, most busy premises retest annually, while hospitals, care homes and leisure sites schedule six-monthly checks to maintain continuous evidence of due diligence.

Pendulum testing is compact and self-contained, producing no noise or residue. Our technician works within cordoned sections, usually completing each area in minutes, so your team and customers can keep moving with minimal disturbance and absolutely no need to close facilities.

Yes. Our reports follow HSE guidelines and include raw readings, environmental notes, photographs and calibration certificates. Insurers and solicitors recognise this format, so supplying it can reduce premiums, support claims defensibility and evidence that you maintain a robust risk-management programme.

We regularly verify slip resistance in showers, changing rooms, commercial kitchens and spa decks using the pendulum’s Four S slider designed for barefoot conditions. By replicating water film effects we provide realistic data that helps you choose coatings or cleaning regimes wisely.

Beyond testing we can arrange professional surface treatments, supply certified anti-slip tapes, or train your cleaning staff on best-practice maintenance. This holistic support ensures improvements are sustainable, measurable and fully aligned with the risk profile highlighted in your pendulum report.
