01 / The credential that matters

Anyone can buy a pendulum. Almost no one is accredited to use one.

There is a fundamental difference between owning the equipment and being formally assessed by the United Kingdom Accreditation Service to operate it. For school flooring — where slip incidents lead to pupil injury, parental complaints, RIDDOR reports, insurance claims and Ofsted scrutiny — only one of these is defensible.

Surface Performance — UKAS Lab No. 7933

UKAS Accredited Testing Laboratory

  • Operating under ISO/IEC 17025 — the international standard for testing laboratory competence.
  • Equipment traceably calibrated against national standards, with calibration records on every report.
  • Test methodology independently audited by UKAS surveillance assessors.
  • Reports carry the UKAS endorsement mark — accepted by HSE, courts, insurers and DfE.
  • Operated by Surface Performance Ltd — a named, registered company with a physical UK lab address.
  • Sector-specialist team familiar with DfE Building Bulletins (BB103, BB104) and Good Estate Management for Schools (GEMS).
Typical "slip testing" website

Unaccredited resellers & lead-gen sites

  • Use a pendulum but are not themselves UKAS accredited — they may even claim the equipment is "UKAS-approved", which is misleading.
  • No independent assessment of method, environment, or operator competence.
  • No verifiable company name, address, or laboratory schedule on the website.
  • Generic, templated reports — fragile under scrutiny in court or after a serious pupil injury.
  • Anonymous testimonials. No insight into the people doing the work.
  • Often subcontract or refer the job onward — you do not know who is actually walking onto your school site with pupils present.

The phrase "UKAS-approved pendulum" — used by a number of lead-generation websites in this sector — is a category error. UKAS does not approve equipment; UKAS accredits laboratories and testing bodies. If you ask the question "is your company UKAS accredited under ISO 17025?", the answer separates the genuine providers from the resellers in a single sentence.

03 / School areas

Every school zone has its own slip profile.

School floors are not a single risk. A swimming pool, a science lab, a Year 1 classroom and a sixth-form refectory all behave differently under contamination. Our school surveys are designed around the actual contaminants and footfall patterns of each zone — not a generic walkthrough.

A — 01

Swimming pools & poolside

Barefoot wet environments — the single highest slip-risk zone in any school. Tested with the Slider 55 (barefoot) methodology and full poolside, footbath and shower coverage.

PTV ≥ 36 (barefoot, wet)
A — 02

Sports halls & gyms

Sweat, water-bottle spills and dust on sprung wood, PU or vinyl. Slip-risk varies dramatically across a school day. Sport-specific PTV benchmarks applied where relevant.

PTV ≥ 36 (sweat-contaminated)
A — 03

Changing rooms & showers

Wet barefoot environments alongside footwear traffic. The mixed-contamination profile is one of the trickiest in any school estate. Tested with appropriate sliders.

PTV ≥ 36 (barefoot, wet)
A — 04

Dining halls & kitchens

Food, drink, oil and water contamination. Lunch-period footfall concentrates risk into a 60-minute window. Tested with contaminants representative of actual lunchtime conditions.

PTV ≥ 36 (water/food)
A — 05

Toilets & WC blocks

The most common location for in-school slip incidents. Splash-water contamination on small ceramic tiles is a persistent issue across all phases.

PTV ≥ 36 (wet)
A — 06

Science labs & DT workshops

Chemical spills, water taps, dust and cutting fluids on resin or vinyl flooring. Distinct risk profile from general classroom space.

PTV ≥ 36 (specific contaminants)
A — 07

Stairwells & landings

Tread surfaces, stair nosings and landings — high pupil traffic, often in older buildings with worn surfaces. Subject to BS 5395 and Building Regulations Part K.

Treads + nosings tested
A — 08

Entrances & main reception

Tracked-in rainwater, mud and leaves. The first surface a parent sees, and the most common location for visitor slip claims. Matting performance assessed.

PTV ≥ 36 (wet)
A — 09

External paving & playgrounds

Tarmac, paving, MUGAs and outdoor learning surfaces — tested under wet conditions, with attention to leaf-fall, algae and ice-prone zones.

PTV ≥ 36 (wet)
04 / Methodology

A four-stage process, traceable end to end.

Every school survey we deliver is auditable from initial scoping through to the final UKAS-endorsed report. No subcontractors, no anonymous testers, no templated conclusions. All operatives DBS-checked.

i

Scoping & pre-visit

We work with your School Business Manager, Estates lead or MAT Operations Director to identify priority zones — sports halls, pools, dining areas, recent installations, post-incident investigations. Floor plans annotated, contaminant assumptions agreed in writing.

ii

On-site testing

DBS-checked, trained operatives carry out BS 7976-2 pendulum testing with traceably calibrated equipment, in both dry and wet (contaminated) conditions. Surface roughness measured where appropriate. Photographic and locational evidence captured at every test point. Term-time and holiday scheduling.

iii

UKAS-endorsed report

Within five working days you receive a full report carrying the UKAS endorsement mark: PTV results in dry and wet, surface roughness data, slip potential classification (HSE), photographic plates, plan-marked test locations, and clear pass/fail commentary against DfE BB103/BB104 guidance. Reports are written to stand up to Ofsted, RIDDOR and adversarial scrutiny.

iv

Recommendations & retest

Where corrective action is required, we set out the options — cleaning regime change, anti-slip treatment, surface replacement — and the expected impact on PTV. We are independent of all anti-slip product manufacturers. We do not sell flooring. We do not sell treatments. The only product is the report.

05 / Coverage

Nationwide service. Term-time scheduling.

We deliver on-site school slip testing across England, Scotland, Wales and Northern Ireland — typically within two to three weeks of booking, with priority response available for post-incident investigations and prioritised summer holiday slots for full-estate programmes.

06 / Questions

Frequently asked, honestly answered.

What does UKAS ISO 17025 accreditation actually mean for my school?
It means the testing organisation — not just the equipment — has been independently audited for technical competence, traceability, impartiality and integrity of results. UKAS does not "approve" pendulums; UKAS accredits laboratories. After a serious pupil slip injury, an Ofsted finding, or an HSE investigation, an accredited report is the only one that can be relied on without challenge. Many sites in this market trade on the word "UKAS" without holding accreditation themselves. Always ask: is your company accredited under ISO/IEC 17025, and what is your laboratory schedule reference? Surface Performance Ltd is UKAS Testing Laboratory No. 7933.
What pendulum test value (PTV) should school floors achieve?
The HSE recommends a minimum wet PTV of 36 for low slip potential. In a school, that minimum needs to be tested under the contaminants actually present — water and cleaning residue in toilets and corridors, sweat in sports halls, food and drink in dining rooms, chemicals in science labs. Swimming pools and shower areas must be tested with the barefoot Slider 55, which is a different methodology entirely. Smooth vinyl in classrooms often requires surface roughness (Rz) measurement — a pendulum reading alone can mislead on glossy surfaces.
Are schools legally required to slip test their floors?
Schools have duties under the Health and Safety at Work Act 1974, the Workplace (Health, Safety and Welfare) Regulations 1992 (Regulation 12 — floors must not be slippery so as to expose any person to a risk to their health or safety), and the duties placed on governing bodies and proprietors. DfE Building Bulletins 103 (mainstream schools) and 104 (SEND schools) reference slip resistance requirements, as does the DfE's Good Estate Management for Schools (GEMS) framework. Routine pendulum testing is the recognised mechanism for evidencing duty of care, and is increasingly requested under Ofsted's premises and safeguarding scrutiny.
How often should school floors be slip tested?
As a baseline, we recommend an annual survey of high-risk areas, plus testing after every new floor installation or refurbishment (PSBP, CIF, SCA), after a change of cleaning chemistry or supplier, and after any reportable slip incident. Swimming pools, sports halls and shower blocks warrant more frequent intervals — typically six-monthly. Many MATs build slip testing into their annual estate condition cycle alongside fire safety, asbestos and water testing.
Can you test during term time without disrupting lessons?
Yes. A typical pendulum test takes a few minutes per location and the equipment is fully portable. We routinely work in occupied schools, around lesson timetables, lunch periods and PE schedules. All operatives are DBS-checked and used to operating in school environments. That said, many schools and MATs prefer to schedule full-estate testing during half-term or summer holidays — we offer prioritised summer holiday slots for exactly this reason.
Do you offer Trust-wide and Local Authority programmes?
Yes — and they're our preferred way of working. Trust-wide and LA-wide programmes are typically 10–30% more cost-effective than ad-hoc per-school testing, and they produce the consistent, comparable evidence base that central Estates and H&S teams need. Single point of contact, consolidated annual reporting, and predictable per-site pricing.
Are you independent from anti-slip product manufacturers?
Yes — completely. Surface Performance Ltd does not sell flooring, anti-slip treatments or coatings. Our only deliverable is the testing and the report. That independence is fundamental to UKAS accreditation under ISO 17025 and to the credibility of the report itself. Where corrective action is needed, we set out the options impartially.
Can your reports be used in court or for an insurance claim?
Yes. Our reports are written to the same standard expected of expert witness evidence in personal injury cases. UKAS-endorsed reports carry the strongest possible weight in litigation and regulatory proceedings, and we have produced reports used in both claimant and defendant instructions, RIDDOR investigations and Ofsted matters.
