safety and reliability of the boiler and have the Service Record

BENCHMARK STANDARD
The Benchmark initiative is a code of
practice to encourage the correct
installation, commissioning and servicing
of domestic central heating boilers and
system equipment.
A “checklist” is dispatched with every boiler. This is a vital
document that needs to be completed by the installer at the time
of installation. It confirms that the boiler has been installed and
commissioned according to the manufacturer's instructions.
Ensure that the service engineer completes the
Service Record in the Benchmark Checklist after
each service. The Benchmark Checklist and service
interval record can be found at the rear of the
Installation, Commissioning and Servicing
Instructions.

General information

The log book provides space for the recording of regular servicing
of the boiler/heating system and this can become a valuable
document when, for example, you wish to sell the property. The
log book will show a potential purchaser that the heating system
has received regular professional maintenance and servicing
during its lifetime.
The Benchmark initiative aims to:
•Raise standards among professional installers
•Build and maintain high safety standards in the industry
•Improve customer satisfaction levels
•Make a contribution to the nation's commitment to climate
change
