When it comes to running a safe and legally compliant business in the UK, one area that can’t be overlooked is gas safety. Whether you manage a restaurant, office, warehouse, or shop, if your business uses gas appliances, you likely need a Commercial Gas Safety Certificate.
In this guide, Scalex Technology breaks down what these certificates are, who needs one, and how to stay compliant with UK gas safety regulations.
What Is a Commercial Gas Safety Certificate?
A Commercial Gas Safety Certificate (also referred to as a CP42 or CP12 certificate) is a formal document provided by a Gas Safe registered engineer confirming that your commercial gas appliances, pipework, and systems have been inspected and meet legal safety standards.
It’s the commercial equivalent of the homeowner’s gas safety check, but it’s a legal requirement for many businesses.
Who Needs a Commercial Gas Safety Certificate?
Any UK business premises that uses gas appliances, pipework or heating systems must have regular safety checks and certification.
You’ll need a certificate if your business:
- Uses gas boilers, ovens, heaters or other appliances
- Has a gas meter or piped gas installation
- Operates in hospitality, education, healthcare, or industrial sectors
- Rents or leases commercial properties to tenants
Landlords of commercial properties are also legally responsible for ensuring valid certificates are in place for tenants.
Types of Commercial Gas Certificates
Different industries and installations may require specific certificates:
| Certificate Type | Description |
|---|---|
| CP12 Commercial | Standard gas safety certificate for commercial premises |
| CP42 | Required for catering businesses (e.g. restaurants, cafes) |
| CP15 | Testing gas installation tightness |
| CP16 | Purging and reinstating gas services |
| CP17 | Installation pipework testing |
If you’re unsure which applies to your premises, speak to a certified engineer or an energy compliance advisor at Scalex.
How Often Do You Need a Gas Safety Certificate?
By law, a commercial gas safety inspection must be carried out at least once every 12 months. More frequent checks may be needed for high-risk environments, such as kitchens or manufacturing sites.
What Does a Gas Safety Inspection Cover?
A qualified Gas Safe engineer will assess the following during your inspection:
- Gas pipework condition
- Appliance functionality and safety
- Ventilation and airflow
- Pressure tests and leaks
- Flue testing
- Emergency control valves
- Combustion analysis
Once complete, the engineer will issue your certificate, detailing any faults found or work required.
