The Benchmark Scheme
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 Hot water Industry
Council who manage and promote the scheme. Visit
