Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what are (1) the original target, and (2) current forecast, for the uptake of metering and monitoring service packages under the Domestic Renewable Heat Incentive scheme; how many packages have been allocated in each year since introduction; and what evaluation has been undertaken of their effectiveness in identifying underperformance or non-compliance.

The Metering and Monitoring Service Package (MMSP) was designed to support participants and installers on the Domestic Renewable Heat Incentive to understand how heating systems are working in specific households and not to serve as a compliance tool. This was an optional measure for participants and was demand driven with 11,255 packages available in total. Ofgem's published data indicates that 3,530 applications were approved as of September 2023, with information for the preceding years attached.
