Look for the yellow Gas Safe Register triangle not the orange CORGI registration badge.
Anyone carrying out work on gas must be registered with 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, boilers, hobs, ovens or fires in your home or workplace.
You must only use a Gas Safe registered engineer for any type of gas work, including installation, maintenance and servicing.
