UKAS accredited pendulum surveys for supermarkets, department stores, shopping centres and independent retailers. Proactive risk assessment, post-incident investigation, and pre-litigation evidence.
Retail premises combine three factors that make slip claims almost inevitable: high pedestrian footfall, frequent wet contamination, and visible CCTV evidence that plaintiff solicitors can rapidly obtain. A typical supermarket handles more pedestrian movements in a week than many office buildings handle in a year — and every one of those footsteps is a potential claim.
Public liability insurers processing supermarket claims frequently cite the same failure patterns: inadequate cleaning records, floors specified for dry performance only, and the absence of independent slip resistance evidence prior to the incident. The first two are operational. The third is the one a UKAS accredited test report solves before it's needed.
Entrance matting zones, produce aisles with frequent water contamination, fresh fish and meat counters, bakery and deli areas, wine and beer aisles (breakage risk), the checkout zone, customer toilets, and the back-of-house warehouse. Each zone has a different contamination profile and typically requires a different PTV target.
Polished stone and terrazzo entrances — often far below PTV 36 in the wet despite an expensive appearance. Escalator landings. Food halls and cafe areas. Dressing rooms. Stair nosings and landings.
Shared mall flooring, food court seating areas, common toilets, entrance vestibules, atrium feature flooring, and service corridors. Landlord-managed flooring is a particular claim hotspot because multiple tenants operate differing cleaning regimes on the same surface.
Small-format retail often has vinyl or timber floors with varied wear. Entrance zones near revolving or automatic doors accumulate water from customers' umbrellas and shoes in wet weather — a PTV of 18 or lower is common in these zones even when the rest of the shop tests at 40+.
Shop floors at petrol stations are a specific category — foot traffic from the forecourt brings fuel, diesel, oil and road debris onto the shop floor. Standard retail testing is supplemented with oil-contaminated pendulum testing for this environment.
A claim has been intimated. The retailer's insurer wants independent evidence of the floor's slip resistance at the approximate time of the incident. A rapid UKAS accredited survey — ideally within 48 hours — captures the as-is condition before any remediation work compromises the evidence.
Forward-looking retailers commission annual or biennial slip surveys across their estate. A baseline PTV record for every store, updated on a rolling basis, is powerful evidence of a documented risk management system — which is exactly what section 3 of the Health and Safety at Work Act 1974 requires.
The specification says the new floor will achieve PTV 36+ in the wet. A UKAS accredited acceptance test confirms whether it does. BS 8204 is explicit that new floor installations should be pendulum tested on completion. Many aren't.
A retailer switches to a new cleaning product or chemical supplier. Some surfactant-heavy products leave a residual film that dramatically reduces PTV. Periodic re-testing after a product change catches this before a claim does.
A note on discretion. We routinely test in trading hours without disturbing customers. Testing takes under 10 minutes per location and the pendulum is discreet enough that shoppers rarely register its presence. Out-of-hours testing is available for premium retail or whenever operational disruption cannot be accepted.
| Retail area | Suggested PTV target (wet) | Typical issue |
|---|---|---|
| Entrance lobby / matted zone | 36+ | Water tracked from street |
| Main sales floor | 36+ | Spills, cleaning residue |
| Fresh food / deli | 36+ | Frequent water and food debris |
| Customer toilets | 36+ | Water splash around basins |
| Stair nosings and landings | 40+ | Transition edges |
| Sloped ramps | 40+ (gradient-adjusted) | Increased slip angle |
| Back-of-house wet zones | 40+ | Continuous water contamination |
Retail public liability claims are defended on documented evidence. When a brief is submitted to claims counsel, the strongest file contains all of the following:
The pendulum report is the piece that ties all of the others together. Without it, the cleaning log is unverifiable, the risk assessment is aspirational, and the CCTV shows a slip on an unquantified surface.
From the field. See Case 1 in our case studies — a supermarket post-incident survey where testing identified an undersized entrance mat as the specific defect.
