How do I know whether the gas installer is CORGI registered?

Before allowing anyone on to your property, ask to see their CORGI identification (ID) card. The card tells you all you need to know about the installer (and their employees) you are going to use. The front shows the operative's photograph, name, trading title, CORGI registration number and card expiry date. The reverse lists the areas of gas work the holder is competent to carry out, with certificate expiry dates next to each entry if they expire before the card does. If you wish to check the validity of the card, call the number on it (0870 401 2300) or use our on-line validation service.
