BENCHMARK

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. Visit www.centralheating.co.uk for
