Benchmark places responsibilities on both manufacturers and installers. The purpose is to ensure that
customers are provided with the correct equipment for their needs, that it is installed, commissioned
and serviced in 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.
