Local regulations
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 a competent person approved
at the time by the Health and Safety Executive and that it
meets the requirements of the appropriate Building Regu-
lations. The Benchmark Checklist can be used to demon-
strate compliance with Building Regulations and should be
provided to the customer for future reference.
Installers are required to carry out installation, commission-
ing 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.
