Gas Safety Certificates

A gas safety certificate is a document that confirms a gas appliance is safe to use and has been checked by a Gas Safe registered engineer. Known as a CP12, this certificate includes:

• Engineer’s details and gas safety registration number
• Property address
• Details of location and type of each gas appliance tested
• Any issues and actions needed to solve them
• Date of when the next inspection is due

Our gas safety engineers will complete a thorough inspection of your gas appliances to be confident they are safe. During the check, they will typically:

• Check for any gas leaks around your appliances and pipework
• Make sure that the flue (which removes combustion gases) is clear and working correctly
• Complete a flue combustion test to be sure the appliance isn’t producing any carbon monoxide
• Check the appliance has adequate air supply and ventilation
• Test that safety devices are working correctly so the gas supply can be cut off if a flame goes out

Gas safety checks and certificates are essential for several reasons. First and foremost, they protect you and your household from the dangers of gas leaks, fires, and carbon monoxide poisoning. Carbon monoxide is a particularly insidious threat as it’s a colourless, odourless gas that can be fatal. By having regular checks, any issues can be identified and solved before they become life-threatening.

Plus, some home insurance policies may also be invalidated if a gas-related incident occurs and you don’t have a valid gas safety certificate. Having regular checks therefore ensures you’re covered should the worst happen.
