heat capacity, heat generated, and heat supplied applying to the heat source in question. The Secretary of State must also be supplied with practical information about the location of the heat supply, the type of building in which it is contained, and the type of customer supplied. Following the initial notification this information will need to be updated with the Secretary of State every four years.
By 31 December 2016, the supplier must install meters in its building which measure the individual consumption by the end-user in all cases unless it is not cost-effective or not technically feasible to do so. The regulations contain a test for whether or not it is cost-effective for meters to be installed. Where it is not cost-effective, this must be considered again every four years and meters have to be installed upon any substantial reconstruction of, or installation of new services in, the building.
By 31 December 2016 heating for each end-user will be separately metered where possible based on actual consumption.
Non compliance by a supplier is a criminal offence and punishable with a fine of up to £5,000 per offence plus daily penalties of £500 until the breach is remedied.
