From 1 April 2009, the CORGI gas standard will no longer exist. The CORGI shield was the logo that many consumers looked for reassurance when using a recommended plumber or recommended central heating engineer . The Gas Safe Register replaces CORGI and is there to protect consumers from unsafe gas work. Being a Gas Safe Register engineer shows they are competent and safe to work with gas. If you're looking to use any companies for gas work through The Disc Directory, make sure that they come highly recommended and are members of the new Gas Safe Register. Don't take a risk, use the Disc!
