Gas Safe Register replaced CORGI as the gas registration body in 2009. This is the list of gas engineers who have a registration to work safely and legally on boilers, cookers, fires and all other gas appliances.
The law states that all gas engineers must be on the Gas Safe Register. The role of the Register is to act as a licensing body. Gas Safe Register is not a membership body for engineers, nor a trade association. They investigate reports of illegal gas work. The information they gather is then passed on to the Health and Safety Executive, who then have the power to prosecute.
