The only specialist slip testing programme in the UK built around car park operations — from a single supermarket apron to a 28-deck multi-storey portfolio. UKAS ISO/IEC 17025 accredited pendulum slip test methodology, evidence-grade slip testing, court-admissible reports.
Our pendulum slip test programmes are designed for car parks, by people who understand car parks. Generic slip testing providers send the same scope of works to a multi-storey as they'd send to a hotel lobby. We don't — every car park slip test we run is calibrated to the specific surfaces, traffic patterns and risk register of the asset in front of us.
Slip test visits planned around your operational lulls — typically 22:00–05:00 to avoid revenue-bay closure during peak occupancy. Every pendulum slip test is completed without disrupting paying customers.
Multi-site portfolios — national operators, supermarket estates, retail park landlords, NHS Trust estates and local authority portfolios — covered under one slip testing contract, one point of contact, one quarterly pendulum slip test report.
UKAS-accredited slip testing evidence accepted by insurers, claims handlers and the courts. Decisive in personal injury defence work, where a credible pendulum slip test record is often the difference between settlement and dismissal.
Slip testing coverage from Aberdeen to Truro, Belfast to Dublin — single rate card, no regional surcharges. Every pendulum slip test performed by directly-employed Surface Performance technicians.
Many providers describe themselves as offering "pendulum slip test" services. Only UKAS-accredited slip testing reports survive scrutiny in court, in HSE investigation, and at insurer claim review. Surface Performance is one of just three UK pendulum slip test laboratories holding live UKAS accreditation.
Car parks present a uniquely varied surface vocabulary in a single asset — power-floated concrete on the structural decks, mastic asphalt on the roof, polymer-modified resin on the helical ramps, polished porcelain at the lift-lobby thresholds, and painted line markings everywhere. Each surface needs its own pendulum slip test methodology and its own slip testing slider rubber, with a distinct PTV profile under wet, contaminated and frost conditions.
Standard intermediate-deck finish across most UK multi-storeys — dry pendulum slip test values are usually compliant, but a sustained wet-shoe-carry-in pattern from inclement weather pushes wet PTV below the 36 threshold at column bases and bay-line intersections. Our pendulum slip testing is performed under realistic wet conditions, not the manufacturer's idealised baseline.
Spiral and split-level ramps are the single highest-incident pedestrian zone in most multi-storeys. Anti-slip resin coatings degrade at predictable rates, and pendulum slip test programmes should run on an 18-month cycle rather than annually. Slip testing at the actual ramp gradient, not as a flat-surface assumption.
The roof-deck environment is the worst surface exposure in any car park — full weather, oil drips, painted line markings, bird fouling, ponding. Wet-condition pendulum slip testing is non-negotiable, and seasonal slip testing (summer baseline + winter contaminated pendulum slip test) is the only credible programme.
The defined high-claim zone in any car park. Stair treads, polished-porcelain lobby floors and the rubber-mat threshold all generate distinct slip patterns and need separate pendulum slip test scope. UKSRG slider 96 testing for stair treads, slider 55 for lobby finishes — different pendulum slip test regimes, separately reported.
EV charging bays generate distinct exposure — extended dwell times, cable-runout zones, post-charge condensation drips. Newly-installed EV bay surfaces (typically a thermoplastic anti-slip overlay) need first-12-month verification by pendulum slip test as a minimum for any defensible slip testing record.
Painted line markings are inherently lower PTV than the surrounding deck — the line itself is a slip exposure. Targeted pendulum slip test points on line paint alongside the surrounding surface, and re-testing after every line-marking refresh, are essential elements of a credible car park slip testing programme.
Generic slip testing providers send the same pendulum slip test report regardless of asset class. Car parks face exposure conditions that simply don't exist in retail, hospitality or healthcare interiors — and they need pendulum slip testing scoped accordingly.
Every parked vehicle is a contamination source. Bay-centre drip patterns generate a wet-equivalent PTV exposure even on dry decks — pendulum slip testing using slider 55 (4S rubber) is the correct slip test protocol for these zones.
Pedestrians entering from rain saturate the entry pedestrian-route zone for up to 6 metres. Lift-lobby and stair-core thresholds are the primary residual-wetness zones in the entire structure and the highest-priority pendulum slip test points.
Ramp surfaces face combined gradient-and-surface risk. UKSRG 36 PTV applies on flat surfaces — ramps require uplift to PTV 50+ on a 1:10 gradient. Pendulum slip testing performed at the actual ramp gradient is the only credible methodology.
Roof-deck surfaces drop below freezing 40+ nights per year in most UK regions. Frost-condition pendulum slip test evidence is a documented winter requirement for any open-deck or top-deck risk register.
Stair-tread nosings degrade at 5–10× the rate of the tread surface itself. A compliant tread does not equal a compliant nosing — separate slip test points and separate pendulum slip test reporting are required.
Standard chlorinated-rubber bay-line paint has a wet pendulum slip test value in the high teens. Anti-slip-additive line paint must be specified and verified by post-application slip testing — line paint is a recurring failure mode in car park slip testing programmes.
Charging-cable runout zones are pedestrian routes with their own exposure — cable drape patterns create combined trip-and-slip risk that needs documented slip testing as EV provision expands across UK estates.
Disabled and Mother-and-Baby bays carry elevated duty-of-care expectations. Disabled-bay pendulum slip test results are now expected in any post-incident defence — assume separate slip testing reporting line.
Polymer anti-slip coatings on ramps and pedestrian routes degrade visibly within 18–36 months. Specifying the coating is the easy part — verifying it still performs by pendulum slip test after two winters is the slip testing programme that matters.

View All Slip Testing Locations →Slip testing pricing for car parks depends on scope — a single-deck post-incident pendulum slip test typically falls in the £500–£900 range, while a comprehensive multi-deck slip testing programme covering all decks, ramps, stair-cores and the roof deck is usually in the £1,800–£4,500 range per visit. Multi-site portfolio slip testing programmes (10+ car parks) attract negotiated rates.
Fixed-price written slip test quotations are issued within one working day. No per-test charges, no hidden access surcharges, no slip testing surprises on the invoice.
Annual pendulum slip testing is the recommended baseline for most UK car parks, with high-risk zones (helical ramps, stair-tread nosings, lift-lobby thresholds, top decks) slip tested every 6–12 months. Roof and top decks benefit from summer-baseline and winter-contaminated separate slip testing rather than annual averaging.
Additional pendulum slip test visits should be triggered after a reportable slip incident, refurbishment, change of cleaning chemistry, line-marking refresh or anti-slip coating renewal. Continuous slip testing evidence is the strongest defence in any subsequent claim.
A typical pendulum slip test takes 15–20 minutes per test point and requires only a single-bay closure during the actual measurement. We rotate slip testing through 4–6 bays at a time using cones, completing a full deck pendulum slip test assessment in 90–120 minutes with minimal revenue impact.
For high-occupancy assets — airport long-stay, supermarket peak hours, central-zone city multi-storeys — we run pendulum slip test visits between 22:00–05:00 to eliminate revenue disruption entirely. Out-of-hours slip testing is included in the standard rate card; no surcharge.
Car park pendulum slip testing is performed under BS 7976-2 / BS EN 16165:2021 (the British and European pendulum slip test standard), UKSRG Issue 6 (2024) (UK Slip Resistance Group slip testing guidelines), and UKAS ISO/IEC 17025 (slip testing laboratory accreditation). For pedestrian routes within the structure we additionally apply PAS 13 walkway code of practice and BS 8300-1 for accessible-route slip testing.
UKAS-accredited slip testing reports under BS 7976-2 are the highest evidential standard available in UK personal injury work. Our pendulum slip test reports are routinely cited in claims defence work for car park operators, retained by insurers as the documentary basis for liability decisions, and accepted as expert evidence in County Court and High Court proceedings.
Many operators retain us specifically to maintain a continuous pendulum slip test evidence record across the asset — a defensible slip testing audit trail that pre-dates the next incident, not a reactive slip test commissioned afterwards.
We hold UKAS ISO/IEC 17025 slip testing accreditation, issued and audited by UKAS — the only national accreditation body recognised by the UK Government for slip testing laboratories. The difference matters: many slip testing providers display ISO logos but are not UKAS-accredited, which makes a decisive difference when pendulum slip test data is presented to a court, insurer or HSE inspector.
The pendulum slip test (also called the BS 7976 pendulum test, the TRRL pendulum, or the British Pendulum Tester) is the HSE's preferred in-situ slip testing method. A pendulum slip test simulates a heel strike on a wet or dry surface and measures the friction between a standardised slider rubber and the floor — producing a Pendulum Test Value (PTV).
Under UKSRG guidance, a pendulum slip test result of PTV 36 or above indicates low slip risk. The pendulum slip test is the only slip testing method consistently accepted by UK courts and the HSE as evidence of slip resistance — which is why every slip test we deliver is performed using a UKAS-calibrated pendulum slip test instrument.
Whether you operate a single multi-storey, a regional supermarket estate or a national portfolio, we'll return a fully-costed, no-obligation slip testing quotation within one working day.
