The Benchmark checklist is the industry-standard commissioning and service record for hot water storage cylinders, published under the Heating and Hotwater Industry Council scheme. Completing it confirms the cylinder was installed and commissioned to the manufacturer's instructions.
A completed Benchmark record is usually required to validate the manufacturer's warranty. If it is missing or incomplete, a future warranty claim can be refused, so accurate commissioning records matter to both the installer and the customer.
TradePlanr digitises the Benchmark cylinder checklist so you can complete every field on site, capture signatures and produce a PDF that satisfies the warranty requirement without handling a paper logbook.
TradePlanr generates this and 35+ other gas, electrical, oil, plumbing and renewables certificates as proper PDFs — filled on site, signed on screen and stored against the job. Works even with no signal. Free to download.
A Benchmark cylinder record should be completed whenever a new hot water cylinder is installed and commissioned. Most manufacturers make a completed checklist a condition of the product warranty.
It is also completed at each service so the record shows the cylinder has been maintained. A continuous service history helps protect the warranty across the life of the cylinder.
The completed record stays with the customer, typically alongside the appliance documentation, and may be requested during a warranty claim or a property sale.
Record the property address, customer details and the cylinder make, model and serial number so the Benchmark record matches the installed appliance.
Log the storage temperature, thermostat setting, safety device checks and flow rates, confirming each step follows the manufacturer's instructions.
Tick that the customer received the user instructions and a demonstration of the controls, which the Benchmark scheme requires for a valid record.
Capture the installer and customer signatures, generate the PDF and store it against the job so the warranty record is safe and easy to resend.
The Benchmark record is the standard commissioning and service log for cylinders. Manufacturers usually require a completed checklist to validate the warranty, so it protects both you and your customer.
It can. If the commissioning or service record is missing or incomplete, a manufacturer may decline a warranty claim, which is why keeping the Benchmark record accurate and safe is important.
No. Benchmark validates the manufacturer's warranty, while a G3 commissioning certificate relates to Building Regulations compliance for unvented systems. An unvented cylinder installation often needs both.
Yes. TradePlanr lets you complete the full checklist, capture both signatures and produce the PDF at the property, so nothing has to be finished back at the office.
