Scenario

Slip Claim Defendant Pendulum Testing

When you are defending a UK slip-and-trip claim — whether the claimant is a customer, employee, visitor or member of the public — the floor evidence is usually the central technical issue. Independent UKAS-accredited pendulum testing produces the documentary evidence needed for a robust defence, structured from the outset to comply with the Civil Procedure Rules.

The defendant's evidential task

The defendant in a slip claim must usually demonstrate that reasonable practicable steps were taken to manage the slip risk. The strongest combinations of evidence include:

Pre-incident periodic pendulum data showing the floor was being monitored
Post-incident pendulum data showing the actual condition at the time of the accident
Documented cleaning, inspection and signage protocols
Risk-assessment records pre-dating the incident
Training records for staff with cleaning and inspection duties

Pendulum data is the technical heart of this evidence base.

Pre-incident vs post-incident testing

Pre-incident periodic data is gold-standard — it shows the floor was being managed before any specific claim arose. Post-incident testing is necessary where pre-incident data is absent, but is evidentially more vulnerable to challenge: the claimant's expert will argue that the surface has changed in the intervening period.

Where the claim has merit

Independence cuts both ways. Where the test data identifies a genuinely non-compliant floor, the defence position changes — typically toward early settlement at appropriate value rather than contested liability. Knowing this early is more useful to the defendant than having it emerge under cross-examination.

The expert's independence

The expert's overriding duty under CPR Part 35 is to the court, not to the instructing party. A defendant-instructed expert who conceals or downplays adverse findings would breach Part 35 and produce a report that collapses on cross-examination. Defending a claim with a Part 35-compliant expert means the report's defensive value is real and durable.

Multi-claim portfolio defence

For operators facing multiple slip claims across a portfolio over time, periodic pendulum testing across the estate provides an evidence base that is reusable across claims, demonstrating systematic risk management rather than reactive testing in response to each specific accident.
