Heat Network Regulations (2020 Update)

The Heat Network Regulations (2014) introduced a requirement for ‘heat’ suppliers to notify the Department for Business, Energy & Industrial Strategy (BEIS) of any heat network or communal heating systems that they own.  The requirement to complete these notifications, which detail generation capacity, energy generation and number of customers on the network has been in place since 2015 with re-notification required every 4 years or when the building/network is sold.

A second aspect of the regulations was to complete a technical/economic feasibility assessment of whether heat metering could be installed on site.  The original deadline for this assessment to take place and for heat meters to be installed was originally 31st December 2016.  However, the Government deemed that the tool developed for carrying out these assessments was unsuitable therefore there has been no requirement to comply with this part of the regulations.

However, the regulations were subsequently amended in November 2020 to introduce 3No building classes for the installation of metering:

  • Viable – meters must be installed
  • Open – meters must be installed if the result of cost-effectiveness assessment is positive
  • Exempt – meters to not have to be installed

The viable class are those that are newly constructed therefore those buildings constructed on or after 1 September 2022 must have final customer heat metering installed. 

For the open class of buildings, a new cost-effectiveness tool has recently released by the BEIS and all heat suppliers must comply with the requirement to assess the potential to install metering by 27 November 2021 and to install meters by 1 September 2022.  There are two differing types of assessment, a full input cost-effectiveness tool when energy consumption of the building is not known and no quote for heat metering has been received and a reduced input cost-effectiveness tool when the energy consumption is known and a quote for heat metering has been received. 

For commercial buildings, the exempt class are those buildings where heat is distributed by means other than hot water or the cooling system uses a transfer fluid, such as refrigerant rather than water.
