You have just purchased one of our appliances and we thank you for the trust you have placed in our products. Please note that

the product will provide good service for a longer period of time if it is regularly checked and maintained. Our customer support

network is at your disposal at all times.

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 Hotwater Industry Council who

manage and promote the Scheme. Visit www.centralheating.co.uk for

more information.

Building Regulations and the Benchmark Commissioning

Checklist

Building Regulations (England & Wales) require notification of the

installation of a heating appliance to the relevant Local Authority

Building Control Department. This can be achieved via a

Competent Persons Self Certification Scheme as an option to

notifying the Local Authority directly.

The Health & Safety Executive operates the ‘Gas Safe Register’, a self-

certification scheme for gas heating appliances.

This company is a member of the Benchmark initiative and fully

supports the aims of the programme. Its aim is to improve the

standards of installation and commissioning of central heating systems

in the UK and to encourage the regular servicing of all central heating

systems to ensure safety and efficiency.

Building Regulations require that installations should comply with

manufacturer's instructions. It is therefore important that the

commissioning checklist is completed by the installer. The relevant

section of Building Regulations only relates to dwellings. Therefore the

checklist only applies if the appliance is being installed in a dwelling or

some related structure.

The flowchart opposite gives guidance for installers on the process

necessary to ensure compliance with Building Regulations.
