Safety by choice, not by chance
Slip testing across Merseyside
Independent, UKAS-accredited floor testing — grip measured wet and dry. The difference between knowing a floor is safe and hoping it is.
The PTV scale — 36+ is low slip risk.
The difference
A measured floor, or a guess
Slip resistance is invisible and changes over time. Here’s what an independent, accredited test gives you that an assurance never can.

How readings are graded
| PTV result | Slip risk |
|---|---|
| 0–24 | High |
| 25–35 | Moderate |
| 36 + | Low |
| Surface roughness (Rz) | Slip risk |
|---|---|
| Below 10 | High |
| 10–20 | Moderate |
| Above 20 | Low |
The pendulum records a Pendulum Test Value (wet and dry); surface roughness (Rz) is measured in microns where floors get contaminated. Both to BS 7976-2 and BS EN 16165. The full method →
