GAS SAFETY REGULATIONS
Current Gas Safety (Installation and Use) Regulations:-
It is the law that all gas appliances are installed and serviced by a competent person, i.e. CORGI registered personnel. Failure
to install or service appliances correctly could lead to prosecution. It is in your interest and that of safety to ensure compliance
with the law. The manufacturer's instructions must not be taken in any way as over-riding statutory obligations.
The Benchmark Checklist must be fully completed by the installer on installation and commissioning of the boiler. The
Benchmark Checklist is shown in Section 12, page 43, of the Installation and Servicing instructions. All CORGI registered
installers carry a CORGI ID card and have a registration number. Both should be recorded in the Checklist. You can check your
installer is CORGI registered by calling CORGI on 01256 372300.
