Local Context

Slip testing work in Wandsworth.

Wandsworth covers a huge spread — the retail and leisure of Wandsworth Town, the commercial stock along the river, and a rapidly growing residential base. Managing agents, local authority facilities teams, and the hospitality operators along the Wandsworth riverside all commission pendulum testing across SW18 regularly.

On the ground

Riverside developments, communal residential areas, and local authority leisure centres in Wandsworth are the three dominant survey types.

Two measurements. One authoritative report.

01 / Pendulum

Pendulum Test

BS 7976 · HSE Preferred Method

The pendulum friction tester is the method recognised by the HSE, UKSRG and UK courts for assessing slip potential on hard floors. We record Pendulum Test Values (PTV) in both dry and wet (contaminated) conditions, with full photographic evidence, across every London postcode.

  • PTV readings (dry + wet)
  • Multiple test zones per area
  • 4S and TRL rubber sliders
  • Written report + raw data tables
  • Photography + zone references

02 / Roughness

Surface Roughness (Rz)

Rz Micro-roughness · Supplementary

Surface micro-roughness (Rz) correlates strongly with wet pendulum performance. We use a portable surface roughness meter to record Rz values across test areas — a useful supplement to pendulum data and particularly valuable when investigating wear patterns on polished stone, resin and tiled floors.

  • Rz readings in µm
  • Zoned mapping across test areas
  • Wear and cleaning-regime assessment
  • Direct correlation with wet PTV
  • Included alongside pendulum reports

01

Scope

We agree test areas, access arrangements and report format. Most London jobs are scoped within 24 hours of enquiry.

02

Survey

On-site pendulum or roughness testing, typically 1–3 hours. All readings photographed and logged with location references.

03

Analysis

Readings compared against BS 7976 and HSE slip risk categories. Roughness cross-referenced where recorded.

04

Report

Written report with PTV tables, photography, zone plans and plain-English recommendations — usually issued within 5 working days.

What the numbers actually mean.

PTV 0 – 24
High

High slip potential

1 in 20 chance of a slip or greater. Floor fails to meet the recognised threshold and is likely to produce a claim in wet or contaminated conditions.

PTV 25 – 35
Mod.

Moderate slip potential

1 in 10,000 to 1 in 20. Borderline — management controls, cleaning regime and contamination must be carefully reviewed.

PTV 36+
Low

Low slip potential

Better than 1 in 1,000,000 chance of a slip. The floor is considered to meet the recognised UK standard for slip resistance.

Questions Wandsworth clients always ask.

How much does slip testing cost in Wandsworth?

Pendulum slip testing in Wandsworth typically ranges from £450 for a single-location survey to £1,200+ for multi-site or multi-area assessments. Costs depend on the number of test areas, accessibility, whether out-of-hours access is required, and report format. Every quote is fixed, written, and includes the on-site work, report and photography.

What is the Pendulum Test Value (PTV)?

The Pendulum Test Value is the measurement produced by a pendulum friction tester under BS 7976. It is an index, not a unit. A PTV of 36 or above indicates a low slip potential, 25–35 moderate, and below 25 high. The HSE recognises pendulum testing as the method for assessing slip risk in the UK. Readings are taken in both dry and contaminated (wet) conditions to reflect real use.

How long does a Wandsworth slip testing survey take?

A typical single-location pendulum survey in Wandsworth takes 1–3 hours on site. Larger sites or multi-zone surveys may take longer. A written report with PTV readings, photographs, zone references and recommendations is usually issued within 5 working days. Faster turnaround is available for urgent incident response.

Do I need slip testing after an accident?

Slip testing is commonly instructed following a slip or fall incident, either by the occupier's insurer, the defendant's solicitor or the claimant's solicitor. Independent pendulum readings establish whether the floor met the recognised slip-resistance threshold at the time of testing, which is central to liability. Where possible, test as soon as practical — before cleaning regimes change or the floor is replaced.

Can you test floors without disrupting trading hours?

Yes. Out-of-hours testing is standard for retail, hospitality, transport and healthcare clients. We routinely work evenings, nights and weekends across London. Pendulum testing is non-destructive and leaves no residue beyond the water used for wet readings.

Why are wet pendulum readings more important than dry?

Most real-world slips occur when a floor is wet or contaminated — spilt drinks, tracked-in rainwater, cleaning residue or grease. A floor can score a perfectly strong PTV dry and drop into high or moderate slip potential once water is introduced. Wet pendulum readings reflect real use and are usually the metric that matters for both compliance and litigation.
