There is an official site run by Gas Safe Register – previously known as CORGI. Gas Safe Register is the official list of gas engineers who are registered to work safely and legally on boilers, gas cookers, gas fires and all other gas appliances in the UK, Isle of Man and Guernsey.
We want everyone to know how important it is to look after their gas appliances – and the life-threatening consequences of gas leaks and carbon monoxide poisoning.
