The CP42 is the Gas Safe safety record for commercial catering gas appliances, such as ranges, ovens, fryers and griddles found in commercial kitchens. It documents that catering equipment has been inspected and left safe to use.
Commercial kitchens have specific requirements around gas interlocks, ventilation and extraction, and the CP42 captures the checks relevant to that environment.

When it's required
A CP42 is issued when a Gas Safe registered engineer, qualified for commercial catering work, checks gas appliances in a commercial kitchen. Caterers and premises operators arrange these to keep the kitchen safe.
Businesses operating commercial kitchens have health and safety duties to ensure gas catering equipment and its ventilation are safe. The CP42 provides documented evidence of those checks.
The engineer must hold the relevant commercial catering gas qualifications and Gas Safe registration for the appliances being inspected.
