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.
Visit www.centralheating.co.uk for more information.
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.
