The Council for Registered Gas Installers (CORGI) operates a voluntary registration scheme for gas installers in the United Kingdom. From 1991 to 2009 registration with CORGI was a legal requirement for gas operatives and businesses throughout the UK, and before April 2010 in Northern Ireland [1] and Guernsey [2]. CORGI lost its status as official registration body in England, Scotland and Wales on 1 April 2009 and in Northern Ireland and Guernsey [3] in April 2010, with this role being taken on by the Gas Safe Register, run on behalf of the Health and Safety Executive by Capita Group.
