Cost of Gas Work in the UK (2025)
Gas engineer costs range from £60–£120 for a safety certificate to £500+ for new pipework or appliance installation. All gas work must be carried out by a Gas Safe registered engineer.
Gas Safe registration
It is illegal in the UK for anyone other than a Gas Safe registered engineer to work on gas appliances. Always ask for the engineer's Gas Safe ID card and verify their registration at gassaferegister.co.uk. Never use unregistered gas workers — the consequences can be fatal.
What gas work is covered?
Gas engineers install and service boilers, gas hobs, ovens, fires, and wall heaters. They also carry out landlord gas safety checks (CP12 certificates), pressure tests on new gas pipework, and gas meter moves.
