Gas Safe

We are registered with Gas Safe, which replaced CORGI as the gas registration body in Great Britain on 1 April 2009.

Anyone carrying out work on gas must be registered with the Gas Safe Register. If not, they are breaking the law and putting you and your family at risk. Only a Gas Safe registered engineer is legally allowed to install gas appliances. You must only use a Gas Safe registered engineer for any type of gas work, including installation, maintenance and servicing.

Gas Safe Register is the official gas registration body for Great Britainand the Isle of Man, appointed by the Health and Safety Executive for Great Britain and HSWI for Isle of Man.

The Association for Project Safety is a multi-disciplinary membership body for those who operate in, or have an interest in, Health and Safety Risk Management in the Construction Industry.
