Heat Network Update 2015

The Heat Network (Metering and Billing) Regulations 2014 – an update

EVORA can now provide a further update on the above regulations. The National Measurement Office has issued a Scope and Guidance Document covering the regulations.

A heat supplier obligated under the regulations is defined as a person (or organisation) who supplies and charges for the supply of heating, cooling or hot water to a final customer, through either communal heating or a district heating network.

Whoever is supplying the end user with heat is classed as a heat supplier. This includes the supply of heat as part of a package – i.e. through a service contract. The contract does not need to explicitly mention the supply of heat. Shared offices and shopping centres are identified as examples within the guidance document.

Air Conditioned Areas

The regulations define the use of hot water, steam or chilled water. Therefore, air conditioned systems relying on local compressors or purely ducted air are not in scope. However, the provision of chilled water to multiple heat exchangers within a system, supplying more than one customer, is recognised by the regulations as being in scope.


In summary, the guidance confirms that multi-let properties are in scope. As such, heat suppliers must notify the National Measurement Office of the existence of heat networks (i.e. multi-let offices and shopping centres where heating and/or chilled water is provided to more than one tenant in a building). Notification must be completed by 30 April 2015.

EVORA can provide templates that need to be completed. The completed template should then be emailed to [email protected].

Consideration must then be given to installation of heat and hot water meters (or heat cost allocators) to final customers. Cost benefit analysis and subsequent installation must be completed by 31 December 2016.

Please do not hesitate to contact EVORA for more information.
