UKAS slip testing for
prisons and custodial facilities.

Why prisons and custodial facilities commission UKAS accredited slip testing

Custodial facility operators — HMPPS, Serco, Sodexo, G4S operating contracts — face distinct slip exposures at shower and association areas, workshop floors and catering. Incident investigation follows a specific HMPPS framework. UKAS accredited testing supports operator compliance and incident defence.

Specific issues we see in prisons and custodial facilities

• Shower and ablution areas. Barefoot use — Slider 55 protocol.
• Association and corridor areas. High pedestrian volume in limited spaces.
• Workshop and education areas. Industrial and educational floor specs combined.
• Catering areas. Standard commercial kitchen contamination.

Which standards apply

BS EN 16165 Annex C for shod areas; Annex B barefoot for showers. UKSRG Issue 6 protocol.

Common questions

Security clearance?

Our technicians clear to SC level where required.

HMPPS commissioning?

Directly or via operator (Serco, Sodexo, G4S etc.) depending on the contract structure.

Incident investigation — specific protocols?

HMPPS have their own investigation framework. UKAS evidence supports the investigation.

Non-disruptive testing?

Testing runs during lockdown or regime-compatible windows.
