What the Benchmark Checklist Is — and Why It Protects Your Warranty
Your new boiler's warranty depends on more than just a Gas Safe certificate; the Benchmark checklist is the key document.
Understanding the Benchmark Checklist
When you have a new boiler installed, you receive several documents. One of the most important is the Benchmark commissioning checklist. This is a standard document used across the UK heating industry. It is produced by the Heating and Hotwater Industry Council (HHIC). Every major boiler manufacturer requires it to be completed for their warranty to be valid.
Why the Benchmark Checklist Matters for Your Warranty
The Benchmark checklist is a record that your boiler has been installed, commissioned, and handover explained correctly. The installer must fill it in during and after the installation. It covers crucial checks like correct gas pressure, flue safety, and system water quality. When finished, the installer should give you a copy. You must keep this document safe.
If you need to make a warranty claim, the manufacturer will ask for your Benchmark checklist. Without it, they may reject your claim, even if the installer was Gas Safe registered. The checklist proves the work met the manufacturer's specific installation standards. It is your proof that the system was set up properly from the start.
How It Differs From Gas Safe Registration
It is important to understand the difference between Gas Safe registration and the Benchmark checklist. Gas Safe registration is a legal requirement. By law, anyone working on gas appliances must be on the Gas Safe Register. It proves the engineer is qualified and competent to do the work safely.
However, Gas Safe registration does not guarantee the installation meets the specific standards required by your boiler's manufacturer for warranty purposes. An installer can be Gas Safe registered but fail to complete the Benchmark checklist. The checklist is the separate, warranty-specific document that complements the legal safety certification.
What Should You Do With Your Checklist?
When your installation is complete, you should receive a copy of the fully completed Benchmark checklist. Do not accept the job as finished without it. Check that all relevant sections are filled in and signed by the installer. File it with your boiler's user manual and other paperwork. It is as important as your receipt.
Choosing an Installer Who Follows the Process
A reputable installer will always complete the Benchmark checklist as a standard part of their service. They should explain its importance to you. Many trustworthy companies operate on a free-survey-then-fixed-quote model. This means they assess your home first to provide an accurate price and plan for a compliant installation, including the Benchmark process.
Always use a Gas Safe registered installer. Then, confirm they will complete and provide the Benchmark checklist. This two-step check helps ensure your installation is both legal and fully covered by the manufacturer's warranty for years to come.
Frequently asked questions
Is a Gas Safe certificate enough for my boiler warranty?
No. Gas Safe registration is the legal requirement to work on gas appliances, but it does not validate your manufacturer's warranty. You need the completed Benchmark commissioning checklist from your installer for the warranty to be active.
What happens if I lose my Benchmark checklist?
You should contact your installer immediately, as they are required to keep a record. If they cannot provide a copy, your boiler manufacturer may not honour a warranty claim, as the checklist is the primary proof of correct commissioning.
Should an installer charge extra to complete the Benchmark checklist?
No. Completing the Benchmark checklist is a standard and essential part of a professional boiler installation. It should be included in the service provided by any reputable installer operating under the typical UK industry practices.
