We're Surface Performance — a UKAS accredited slip resistance testing laboratory working across every UK city. Insurer claims, council highway defence, post-incident investigations, spec compliance and pre-opening acceptance. All tests performed to BS EN 16165 by an accredited laboratory. Reports land in your inbox within five working days.
Anyone can buy a pendulum tester on eBay. Very few can operate it to ISO/IEC 17025 standards, verify calibration traceably, apply UKSRG Guidelines Issue 6 correctly, and produce a report an insurer, solicitor, local authority or HSE inspector will actually accept.
UKAS accreditation is the only proof that your slip test result is admissible evidence. Without it, you have an opinion. With it, you have data that holds up in court, in claims, in enforcement and in specification.

Costs depend on location, number of test points, and whether the job is standalone or combined with other UKAS survey work. Small single-site surveys typically start at a few hundred pounds plus travel; larger estate audits scale from there. We quote every job individually after a short conversation about what you need evidence of. Call 020 8246 5562 for a fixed fee.
UKAS accreditation is the UK government's formal recognition that a testing laboratory is technically competent. For slip testing, it's the only way to demonstrate to a court, insurer, HSE inspector or local authority that your pendulum result is defensible. Non-accredited tests have no evidential weight — they're an opinion, not evidence. Our UKAS Laboratory Number is 7933.
Most UK mainland locations are routinely accessible within 2-5 working days. For genuinely urgent post-incident work we can often respond within 24-48 hours, depending on field technician availability. London, the South East, West Midlands and Yorkshire are typically same-week; Scotland, Northern Ireland and Cornwall are scheduled with overnight visits.
A UKAS accredited test report — the report carries the UKAS logo, our lab number (7933), the technician's signature, and full method statements. It's the format accepted as primary slip-resistance evidence by UK courts, insurance loss adjusters, the Health and Safety Executive, and local authorities managing Section 41 Highways Act duties. If you need expert witness support, we provide that too.
BS EN 16165 (Annex C — pendulum method), which replaced BS 7976 in February 2022 and is the current UK and European pendulum testing standard. We apply UKSRG Guidelines Issue 6 (Jan 2024) for operational protocol. For highway surfaces we also use EN 13036-4. All three are within our UKAS accredited scope — view our schedule.
