The Gas Safety Certificate was introduced with the increased demand for gas appliances in the home and the frequency of poor-quality installations. The manufacturers of gas boilers and the regulatory board came together to create what is now known as Corgi.
Today, the official body in charge of gas safety is the Gas Safe Register. A governing body for the safe installation of gas boilers and heating services.
The gas safety certificate is a sign-off form from a gas safe registered engineer that has carried out the installation to confirm that it meets the gas safe standard.
