Slip Testing Northamptonshire

Safety by choice, not by chance

Slip safety in Northamptonshire, by the numbers.

Slip risk is invisible until it’s measured. We put a number on it — an independent, UKAS-accredited Pendulum Test Value for every floor — so you can act on data, not guesswork.

By the numbers

The figures that make the case

Some are HSE facts; the cost and reduction figures are industry estimates. Either way, the direction is the same.

No. 1

Most common cause of major injury in UK workplaces — slips and trips.

Source: HSE
25%+

Of all non-fatal workplace accidents are the result of slips.

Source: HSE
£500m+

Estimated annual cost of slips and trips to UK employers.

Industry estimate
~50%

Estimated cut in claim risk through regular accredited testing.

Industry estimate
36

The Pendulum Test Value at or above which a floor is low slip risk.

HSE threshold
1-in-1m

Approximate chance of a slip on a floor testing PTV 36+.

The two scales

What the readings mean

We use two complementary HSE-recognised tests, and we’re accredited for both. The pendulum measures grip directly; surface roughness (Rz) tracks how a floor changes over time and matters most in contaminated areas.

Pendulum Test Value (PTV)

Grip measured wet and dry. 36 or above is the HSE low-risk threshold.

What the numbers ask of you

From data to duty

Every employer and occupier has a legal duty to keep floors safe and to assess the risk; in care settings, the CQC expects slip risk to be actively managed. A measured PTV is what turns that assessment from an opinion into evidence an insurer, the HSE or the CQC will accept.

Independent, and accredited

This service is delivered by Surface Performance — entirely independent, with no connection to any flooring or treatment company and nothing to sell but the test. The same accredited lab trusted on sites from Amazon and Gatwick to British Airways and TUI.
