Gas Safe Register is the official list of gas engineers who are qualified to work safely and legally on gas appliances. By law, all gas engineers must be on the Gas Safe Register. It replaced CORGI. Only use a Gas Safe registered engineer to fit, fix or service your appliances and always check the engineer’s Gas Safe Register ID card. For more information and to find and check an engineer go to www.GasSafeRegister.co.uk or call 0800 408 5500. Take care, be Gas Safe.
