The Benchmark Scheme
Johnson & Starley Ltd is a licensed member of the Benchmark Scheme
which aims to improve the standards of installation and commissioning of domestic heating and hot water systems
in the UK and to encourage regular servicing to optimise safety, efficiency and performance.
Benchmark is managed and promoted by the Heating and Hotwater Industry Council. For more information visit
www.centralheating.co.uk
Please ensure that the installer has fully completed the Benchmark Checklist on the inside back pages of the
installation instructions supplied with the product and that you have signed it to say that you have received a full
and clear explanation of its operation. The installer is legally required to complete a commissioning checklist as a
means of complying with the appropriate Building Regulations (England and Wales).
All installations must be notified to Local Area Building Control either directly or through a Competent Persons
Scheme. A Building Regulations Compliance Certificate will then be issued to the customer who should, on receipt,
write the Notification Number on the Benchmark Checklist.
This product should be serviced regularly to optimise its safety, efficiency and performance. The service engineer
should complete the relevant Service Record on the Benchmark Checklist after each service.
The Benchmark Checklist will be required in the event of any warranty work and as supporting documentation
relating to home improvements in the optional documents section of the Home Improvements.
In the interest of continuous development Johnson and Starley reserve the right to change specification without prior notice.
Johnson and Starley prides itself on it’s ability to supply spare parts quickly and efficiently.
