Combined sub-metering – Electric space heating or water heating and small power equipment

For bedrooms and associated spaces in multi-residential or residential institution building types, it is acceptable, for an electric heating system to be combined with lighting and small power for metering purposes, provided that sub-metering is provided for each floor plate or other appropriate sub-division.

For these building types, sub-metering electric heating in multiple bedrooms may be costly and technically challenging. Where occupants have individual control but are not responsible for paying the utilities bills, the building manager may have little influence on their energy consumption, therefore sub-metering electric heating would provide little or no benefit in meeting the aim of the Issue.

15 Dec 2023 Title updated to clarify that this approach can be applied to both space heating and domestic hot water heating, where appropriate.
