DESNZ publishes consultation outcome on clean heat certification requirements
The Department for Energy Security and Net Zero (DESNZ) has published its response to Part 2 of the consultation on certification requirements for clean heat schemes, confirming its decision to mandate the Microgeneration Certification Scheme as the sole certification scheme for installations under the Boiler Upgrade Scheme (BUS), Energy Company Obligation 4 (ECO4), Warm Homes: Social Housing Fund, and Warm Homes: Local Grant , thereby removing the option for equivalent schemes. This interim measure applies only to technologies currently requiring Microgeneration Certification Scheme certification and excludes heat networks and products governed by PAS 2030. It precedes broader consumer protection reforms to be outlined in the forthcoming Warm Homes Plan. In response to consultation feedback, the government has committed to strengthening Microgeneration Certification Scheme oversight through departmental board representation, a memorandum of understanding, and annual consumer protection reporting.
