How to obtain a gas safety certificate
Ensuring the safety of your gas appliances is a legal requirement that protects your staff, customers, and business.
To get a Gas Safety Certificate, you must hire a Gas Safe registered engineer to inspect all gas appliances and pipework in your business premises. This is a non-negotiable legal requirement for any business using gas, from a large restaurant kitchen to a small café with a single gas hob. The engineer will issue a document known as a CP42 Commercial Gas Safety Certificate, which proves your setup is safe and compliant with UK law.
Why is a Gas Safety Certificate so important?
This certificate is your formal proof that you have met your legal duties under the Gas Safety (Installation and Use) Regulations 1998. Its primary purpose is to ensure the safety of your staff, your customers, and your property. Faulty gas appliances or pipework can lead to dangerous gas leaks, fires, explosions, and carbon monoxide poisoning. An annual gas safety check is essential for preventing these risks. You will be required to show this certificate to inspectors from the Health and Safety Executive (HSE) or your local council, and it's often a condition of your business insurance.
How to get your certificate
Follow these simple steps to ensure you are compliant:
- Find a qualified engineer: The only way to do this is by using the official Gas Safe Register website. It's crucial that you find an engineer who is qualified to work on commercial catering equipment, not just domestic appliances. The website allows you to search for local engineers and check their specific qualifications.
- Arrange the inspection: Contact the engineer to schedule a visit. During the inspection, they will check all your gas appliances for safety, test the pipework for leaks, and ensure there is adequate ventilation. Give them access to all relevant areas.
- Receive your certificate: Once the inspection is complete and the engineer is satisfied that everything is safe, they will issue you with a CP42 Commercial Gas Safety Certificate. This document details what has been checked and confirms it meets the required standards. If any issues are found, the engineer will explain what needs to be done to make them safe.
- Keep it safe: You must keep a copy of your gas safety certificate for at least two years. It's good practice to keep a digital copy as well as the original paper certificate in a safe place where you can easily find it if an inspector asks to see it.
Top Tips
- Set an annual reminder: A Gas Safety Certificate is only valid for 12 months. Put a reminder in your calendar two months before it expires to give you plenty of time to book the next inspection.
- Budget accordingly: This is a recurring annual cost, so make sure you include it in your financial forecasts.
- Installation matters: Remember that any new gas appliances must also be installed by a Gas Safe registered engineer to ensure they are fitted correctly and safely from the start.
