H3450_19-img-200x265-21 - - beckyeat Network Regulations (HNR)

The Heat Network (Metering and Billing) Regulations 2014 are the UK Implementation of Articles 9, 10, 11 and 13 of the EU Energy Efficiency Directive (the same directive that led to ESOS), and the majority of its requirements came into force on 18th December 2014. The remainder come into force by the end of 2016.

The regulations require landlords and developers to understand and act on a lot of information concerning the communal heating or cooling systems that they run, or are in the process of building.

As with all energy legislation, we offer a comprehensive service to enable you to understand and comply with it.

About Heat Network Regulations

These regulations set out a number of requirements regarding metering and billing on all new and existing heating and cooling systems. The legislation will affect all district heating, communal heating and cooling networks in the UK. The regulations will require operators to implement point of delivery (or heat exchange) metering, individual unit metering or heat cost allocation and minimum levels of fair and transparent billing.

The first action is to complete the Notification Template to supply information regarding the location, number and type of buildings and meters in each communal heating system, together with an estimated total per year of:

  • Installed heating capacity
  • Heat generated
  • Heat supplied.


  • Communal Heating – one building and multiple (ie at least 2) final customers are being supplied heat, cooling or hot water.
  • istrict Heating – multiple (ie at least 2) buildings and at least one final customer are being supplied heat, cooling or hot water.
  • publication of details of non-compliance by the compliance bodies.

Key Deadlines

  • 31st December 2015 (revised from 30th April 2015) – Complete and submit information via the ‘NMO Notification Template' to the National Measurement Office (NMO). This must be repeated every 4 years.
  • 31st December 2016 – Complete the ‘DECC Cost Effectiveness and Technical Feasibility Tool’. This will allow you to understand if you are required to install individual consumer heat meters, cooling meters or heat cost allocators.
  • 31st December 2016 – Install building level, or point of exchange, heat meters or cooling meters. This is only required where the point of heat or cooling generation is not within the same building fabric as the heating or cooling generation plant.

Key Issues

A heat supplier only has to fit heat meters where it is cost effective and technically feasible to do so. Appropriate guidelines are set out in the regulations for how to determine this. However, some Article 9 requirements for the installation of meters are not conditional on tests of cost-efficiency and technical feasibility. Individual meters must be installed where:

  • a new district heating or cooling connection is made in a building
  • a building supplied by district heating or district cooling undergoes a major renovation
  • a multi-apartment or multi-purpose building is connected to district heating or district cooling.

These buildings must have a meter installed at the point of delivery or heat exchange. Article 11 of the Directive requires that final customers receive all their bills and billing information for energy consumption free of charge. In addition, the costs for customers in multi-apartment and multi-purpose buildings shall either be:

  • carried out on a not-for-profit basis or
  • where undertaken by a third party, passed on to the final customers (reasonable costs only)

The regulations require that heating costs billed to the end user must be accurate, based on actual consumption and include certain information on the bill such as:

  • Energy prices
  • Comparison with previous use
  • Contact information for the supplier

Any heat meters that are installed should be MID Approved for fiscal billing or similar.

Penalties for non-compliance

Non-compliance can lead to fines of up to £5,000 per offence.
