GENERAL INFORMATION

SERVICING

The boiler must be serviced regularly by a competent, qualified person, such as a Worcester service engineer or other Gas Safe 
registered engineer.

Always use original spares, to help maintain the efficiency, safety and reliability of the boiler and have the Service Record 
completed in the Benchmark Checklist.

The completed Benchmark Checklist will be required in the event of any guarantee work and may be required by the local Building 
Control Inspector.

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.

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

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.
