CP42 Gas Safety Certificate for Commercial Kitchens – Union Plumbing
If you own or operate a commercial kitchen in Huddersfield, Halifax, Bradford, Wakefield, West Yorkshire, Manchester, or Sheffield, you are legally required to hold a valid CP42 gas safety certificate.
This certification is essential for ensuring gas safety in any environment where food is prepared using gas appliances, such as pubs, restaurants, cafés, takeaways, and canteens.
At Union Plumbing, we specialise in issuing commercial catering CP42 certificates, with thorough inspections carried out by qualified Gas Safe engineers.
Who Needs a Commercial Catering CP42 Certificate?
Any commercial catering business using gas appliances must have a valid CP42 certificate. This applies to:
- Restaurants
- Cafés
- Pubs and bars
- Commercial kitchens
- School and hospital canteens
The CP42 certificate ensures your gas installation complies with safety regulations and helps protect your staff, customers, and premises.
What Does a CP42 Certificate Cover?
Our CP42 gas safety inspection includes a full assessment of your commercial kitchen’s gas installation:
- Gas meter and pipework – Checked for leaks and correct sizing
- Appliances – Inspected or serviced to ensure they ignite safely, operate efficiently, and are properly ventilated
- Ventilation and extraction systems – Verified for compliance and safety
- Gas interlock system – Tested to ensure it functions correctly and safely shuts off gas if ventilation fails
Once your installation passes inspection, we issue your CP42 certificate for compliance.
Are Appliance Services Required?
Each gas appliance must be tested to be included on the certificate. While servicing isn’t technically required, it’s highly recommended and is standard company policy at Union Plumbing. A full service includes:
- Deep cleaning
- Preventative maintenance
- Safety and performance checks
Regular servicing minimises the risk of breakdowns, improves appliance efficiency, and extends equipment life — reducing the risk of unexpected downtime.
What Is a Commercial Kitchen Gas Interlock System?
A gas interlock system is a vital safety mechanism in commercial kitchens. It prevents gas from flowing to appliances unless proper ventilation is detected. Depending on the system, it may:
- Perform leak detection before allowing gas flow
- Confirm the extractor system is working
- Control a gas solenoid valve that opens only when safety conditions are met
As part of your CP42 inspection, we check the interlock system. We also install, upgrade, and repair interlock systems in commercial kitchens across West Yorkshire, Manchester, and Sheffield.
What Happens If an Appliance Fails?
If an appliance or part of the gas system fails the inspection:
- The appliance can be isolated from the gas supply
- The remainder of the system can still pass and receive a CP42 certificate
- We’ll provide expert advice on what repairs or upgrades are needed to bring your kitchen up to standard
How to Prepare for a CP42 Certificate Inspection
Before we visit your commercial kitchen:
- Ensure the area is clean and grease-free — built-up grease can be a fire hazard and cause a failed inspection
- Make sure all appliances are accessible for inspection or servicing
- Have your extraction system operational
A clean, well-prepared kitchen allows for a quicker, more efficient certification process.
