Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment he has made of the potential merits of requesting that Ofgem extend their Metering and Monitoring Service Package to include sensors in fossil fuel boilers for those with a hybrid heating configuration to collect data useful to the management of the energy system.

To date, there has been low uptake of hybrid installations with Metering and Monitoring Service Packages (MMSPs) in the domestic RHI. The domestic RHI, including MMSPs, will close to new applications in March 2022. Therefore, the Government does not consider that extending the MMSP requirements to include sensors in fossil fuel boilers in hybrid installations would provide significant useful data on the overall performance of hybrid heating systems.

The Government will be gathering further evidence on the performance of hybrid heating systems as part of the £16.5m Electrification of Heat Demonstration Project. The project is expected to run until March 2022.
