What is a Benchmark certificate?
Benchmark is the industry commissioning checklist completed at boiler installation, recording the setup and readings needed to validate the manufacturer's warranty.
HHIC Benchmark
Central Heating Commissioning (Benchmark)
The Benchmark checklist is the industry commissioning record completed when a boiler or heating system is installed. It captures the install details and commissioning readings needed to demonstrate the system was set up correctly.
Benchmark is administered through the Heating and Hotwater Industry Council (HHIC) and is widely required by manufacturers to validate a boiler's warranty.
TradePlanr lets you complete the Benchmark checklist on your phone at handover, record your commissioning readings, and issue a PDF the customer can keep with their warranty.

When it's required
A Benchmark checklist is completed at the point a new boiler or heating system is installed and commissioned. It should be filled in and signed before the installer leaves site.
Most boiler manufacturers require a completed Benchmark record to activate and maintain the warranty, so it is important evidence for the customer.
The installation and commissioning must be carried out by a Gas Safe registered engineer competent for the work.
