Independent pendulum slip resistance testing to BS EN 16165:2021 (Annex C) — formerly BS 7976-2 — the HSE's preferred method for assessing slip risk on UK floors. Court-defensible reports for property managers, architects, retailers, insurers and litigation teams nationwide.
The pendulum is the only slip resistance test method the UK Health and Safety Executive considers reliable for assessing wet-floor slip risk. Originally specified under BS 7976-2 and now under BS EN 16165:2021 (Annex C), we deliver the test under UKAS ISO/IEC 17025 accreditation — the technical-competence standard required for reports that need to stand up to insurers, building control bodies and the courts.
Our reports are written to comply with CPR Part 35 from the outset. Methodology, calibration record, individual swing data, photographs and reasoned interpretation against HSE guidance — everything a tribunal expects to see.
Expert witness service →Pre-handover BS 8204 testing, insurance-mandated periodic audits, post-installation flooring verification. We run the test, identify the zones that fall short, and provide the documentation needed to close them out.
BS 8204 handover testing →If you manage premises with foreseeable slip risk — supermarkets, hotels, schools, hospitals, leisure — periodic pendulum data is the most defensible evidence available that you have taken reasonable practicable steps under HSWA 1974.
Insurance audit programmes →Different environments produce different slip risks. The pendulum test is the same; the contaminants, contractual thresholds, case law and remedial options vary substantially. Our industry pages cover what actually matters in each context.
If you need to specify, interpret, challenge or defend pendulum test data, these guides cover the technical detail that the UK slip-testing market mostly leaves out. Written for professionals — not for SEO.

Read the guide →Choosing the right pendulum slider for the environment. Slider 96 for shod environments, 55/57 for barefoot — and why the wrong choice invalidates the test.
Read the guide →The structural elements every UKAS-accredited pendulum report should contain — and the warning signs that distinguish a robust report from one that will fold under cross-examination.

Read the guide →The same pendulum test produces evidence used in very different contexts. Each scenario comes with its own evidential requirements, deadlines and downstream uses.
An accident has occurred. The floor needs to be tested before conditions change, repairs are made or weather alters the surface. Time-critical.

Read more →Periodic testing built into insurer-mandated risk management. Schedule, methodology and data retention designed to satisfy underwriters.

Read more →UKAS — the United Kingdom Accreditation Service — is the only national accreditation body recognised by the British Government. ISO/IEC 17025 is the international standard for testing laboratories.
A laboratory holding ISO/IEC 17025 accreditation has been independently audited on technical competence, equipment calibration, traceability of measurement, staff training, and the validity of results. Surveillance audits continue annually.
Many UK pendulum testing providers are not UKAS accredited. The distinction is invisible until a report is challenged.
