Heating engineers are being urged to make the move from the traditional paper Benchmark Commissioning Checklist and Service Record to the new digital Benchmark platform, which now also incorporates commercial appliances and a record of water treatment.

For many years, the Benchmark Checklist has been a familiar part of the domestic heating engineer’s routine, providing a record that a heating appliance has been installed, commissioned and serviced in line with manufacturers’ instructions, Building Regulations and relevant British Standards, but the paper-based version of the Benchmark Commissioning Checklist and Service Record is no longer maintained.

The digital Benchmark Commissioning Record provides installers with a straightforward way to complete and maintain installation, commissioning and servicing records, while giving householders an accessible record of their heating system. The latest version, including all updates, is available online at www.benchmark.org.uk or through the Benchmark apps: iOS and Android.

Commercial appliances now included 

An important development of digital Benchmark is that commercial appliances can now be included.  This will demonstrate that the appliance has been installed and commissioned in line with the manufacturer’s instructions and also provides a record for contractors and building owners that it has been serviced and maintained correctly.

Steve McConnel, Director, ICOM, explains: “For commercial heating, where system performance, reliability and ongoing maintenance are critical, keeping accurate commissioning and servicing records is essential. Several leading commercial heating appliance manufacturers are already using Benchmark and we would encourage the other manufacturers to do the same and provide Benchmark with their model numbers.  Benchmark provides a record for all stakeholders and demonstrates professionalism and competence.”

Water treatment too

Installers can also now record water quality data directly through the Benchmark platform, including inhibitor checks at commissioning and at each annual service. Correct inhibitor concentration has a major impact on system efficiency, reliability and longevity, while poor water quality can adversely affect manufacturer warranties should issues arise.

Recording this information digitally makes it easier for installers to demonstrate what water treatment processes have been carried out and which products have been used. It also provides useful information for engineers returning to service the system, enabling them to identify the inhibitor used, select the correct on-site test kit and top up concentrations where required.

The move is also intended to raise awareness among consumers of the importance of water treatment and the role it plays in maintaining the performance and longevity of their heating system.

In 2024, the British Standards Institution published BS 9593:2024, a new test standard for assessing the performance of chemical inhibitors used in domestic heating systems. This replaces the former NSF Industry Test Standard within the Chemical Inhibitor Approval Scheme and is now referenced in the updated BS 7593:2019+A1:2024.

BS 7593 continues to set out best practice for the preparation, commissioning and maintenance of domestic heating and cooling water systems. The 2024 amendments provide additional clarification, including guidance on inline filters, identification of local water hardness and microbiological growth risks in low-temperature systems operating below 60°C.

Benchmark Online supports compliance with these requirements by providing a structured, consistent way to record key system data over the entire life of the installation.

Digital benefits

The move to digital is designed to give installers and contractors the right tools to make recording installation, commissioning and servicing information easier and less time-consuming. It also provides a clear record they can share with customers, demonstrating that they are doing everything they can to support them properly.

With paper versions no longer maintained, future changes to standards and additions to the Benchmark checklist will only be incorporated into the digital version. Installers and contractors are therefore encouraged to start using Benchmark Online or the Benchmark App and ensure that commissioning and servicing records are completed in full.
