accordance with the manufacturer’s instructions by competent persons and that it meets the requirements of
the appropriate Building Regulations. The Benchmark Checklist can be used to demonstrate compliance with
Building Regulations and should be provided to the customer for future reference.
Installers are required to carry out installation, commissioning and servicing work in accordance with the
Benchmark Code of Practice which is available from the Heating and Hotwater Industry Council who manage
and promote the Scheme. Visit www.centralheating.co.uk for more information.
