Gas Safe Register is the official gas registration body for the United Kingdom, Isle of Man and Guernsey, appointed by the relevant Health and Safety Authority for each area. By law, all gas engineers must be on the Gas Safe Register.

Gas Safe Register replaced CORGI as the gas registration body in Great Britain and Isle of Man on 1 April 2009 and Northern Ireland and Guernsey on 1 April 2010.

The purpose of the Gas Safe Register is to protect the public from unsafe gas work. It does this in two main ways, operation of the Register itself e.g. ensuring that the list of competent and qualified engineers is accurate and up-to-date, inspecting the work of Gas Safe registered engineers and investigating reports of illegal gas work. The second area is to conduct public awareness campaigns to raise awareness of gas safety issues.
