Slip testing
for sports halls
that holds up
in court.

A service of Surface Performance Ltd — one of only three UK sports laboratories holding UKAS ISO/IEC 17025 accreditation for slip resistance testing. Independent, defensible, recognised by HSE, the FA, World Rugby, ITF and FIFA.

How a survey is structured

A sports hall is not a single surface.

A standard sports hall presents at least four functional zones — high-traffic centre court, sport-marked free-throw and goal areas, perimeter run-off, and threshold/entry. Each behaves differently when wet. We sample twelve test locations across the hall, each tested in two perpendicular directions, with the mean of four valid swings reported per direction.

The problem

A pendulum reading from an unaccredited tester is not evidence.

When an injury claim lands, the question is never did you test the floor. It’s can the testing withstand cross-examination. That depends on three things: the standard the test was performed against, the calibration record of the equipment, and the accreditation status of the laboratory.

Most providers offering “sports hall slip testing” in the UK hold none of these. They are floor cleaners, anti-slip product resellers, or generalist surveyors with a pendulum. Their reports do not carry the UKAS endorsement that HSE inspectors and insurers look for.

Surface Performance Ltd, operating as UKAS Testing Laboratory No. 7933, does. We are an independent surface testing laboratory. We do not sell flooring, cleaning chemicals, or anti-slip treatments. The report is the product.

What we test for

Indoor sports surfaces have specific failure modes. We test for all of them.

A school sports hall, a leisure centre badminton court, an indoor tennis facility and a community gymnasium each present a different combination of binder, finish and contamination risk. Boilerplate testing misses the point. Each survey is scoped against the surface specification, the sports played on it, the cleaning regime and the relevant governing-body requirements.

Pendulum / PTV

BS 7976-2 dynamic testing

The HSE’s preferred method. A weighted slider replicates the kinetic conditions of a heel strike. Tested in dry, wet, and where appropriate post-cleaning condition. Calibrated TRL pendulum.

Surface roughness

Rz micro-roughness

Surface micro-texture measured to BS 7976 guidance and correlated against the PTV reading. Critical for reconciling marginal-pass results and for forensic post-incident testing.

Friction coefficient

Force-shoe coefficient

Where required by EN 14904, sliding friction is measured and reported alongside PTV — a separate value with a separate threshold and a separate use-case.

Forensic investigation

Post-incident testing

Following a reported slip injury, we attend at short notice, document conditions, photograph, sample contaminants where present, and produce a report suitable for use in litigation.

PTV thresholds

What the numbers mean.

The pendulum returns a single number. Whether that number is acceptable depends on the surface use, the contamination present and the standard you’re being measured against.

Pendulum Test Value UKSRG slip potential What it means in a sports hall
0 – 24 High Surface fails BS 7976 thresholds. Take out of service or restrict use until remediated.
25 – 35 Moderate Borderline. Often the result of polished or over-sealed timber. Requires action plan.
36 – 64 Low Acceptable for general indoor sport. Most sound, well-maintained surfaces sit here.
65+ Very low Excellent. Common on textured polyurethane and properly conditioned multi-use vinyls.
Note on EN 14904 EN 14904 — the European standard for indoor sports surfaces — specifies a sliding friction coefficient of 80 to 110 µ. This is a separate measurement from PTV and is required for new-build sports surface compliance. We report against both where the project demands it.
Our process

From booking to defensible report, in five working days.

No quote-by-form-fill, no upselling, no surprise add-ons. A specialist scopes the survey by phone, attends site, completes calibrated testing, and issues a UKAS-endorsed report under Lab 7933.

Scope by phone

A specialist — not a sales rep — scopes the survey: surface type, age, suspected issues, governing-body requirements, court count.

On-site testing

UKAS-trained technician attends with calibrated TRL pendulum and roughness gauge. Tests in dry, wet, and contamination-relevant conditions per BS 7976-2.

Lab analysis

Raw data is returned to our laboratory in Sunbury-on-Thames for analysis. Where samples have been collected, they are conditioned for 24 hours per UKAS protocol before further testing.

UKAS-endorsed report

Within five working days. Bears the UKAS endorsement under Lab 7933, with calibration trail, raw data, photographic record, PTV results per location, and clear plain-English recommendations.

UK coverage

Sport surface testing across the United Kingdom and Ireland.

We test sports halls in every region of England, Scotland, Wales, Northern Ireland and the Republic of Ireland. Most surveys are scheduled within ten working days; urgent post-incident attendance is available within 48 hours.
