CORGI was founded in 1970 to protect the public from the dangers of unsafe gas installations. We are acutely aware that poorly trained tradesmen can give the industry as a whole a bad name and bad experiences can make people extremely wary when it comes to employing someone to install or repair a gas appliance.
