Heat Network (Metering and Billing) Regulations

September 26, 2019 | Guidance

The Heat Network (Metering and Billing) Regulations 2014 (HNMBR), require owners and managers of UK heat networks to notify the Secretary of State about the heat networks they operate, every four years.

In line with the EU Energy Efficiency Directive, the regulations aim to drive energy efficiency and transparency within heat networks, ensuring that customers can monitor their energy use and they are provided with competitively priced energy.

The initial deadline for notification was 31st December 2015, and the process must be repeated every four years from the date of your original submission.

HNMBR is regulated by the Office for Product Safety and Standards (OPSS), part of the Department for Business, Energy and Industrial Strategy (BEIS).


You may need to comply with HNMBR, if you charge for the supply of heating, cooling or hot water to an end customer in the UK, through either of the following:

  • A district heating network – two or more buildings with at least two end-users.
  • A communal heat network – a single building, with two or more end-users, such as an apartment or office block.

Part 1 (Required now)

Part 1 of HNMBR is a notification to the BEIS of data from all qualifying heat networks. The first notification deadline was December 2015 and the notification is due every four years from your original submission.

Part 2 (Awaiting release)

Part 2 of HNMBR will be the completion of a technical and financial viability exercise to determine where you must install heat meters or heat cost allocators. Currently, this tool is waiting on release from BEIS, with no launch date set at present. This tool will confirm whether heat meters or cost allocators will need to be installed.

See our guide on the proposed changes to find out more.
