DESNZ publishes response to consultation on revisions for Year 2 of Clean Heat Market Mechanism
The Department for Energy Security and Net Zero (DESNZ) has published the response to its May 2025 consultation on proposed revisions to the Clean Heat Market Mechanism (CHMM), ahead of Scheme Year 2 (2026–27). Following analysis of stakeholder feedback, DESNZ has set the heat pump target for Year 2 at 8% of relevant boiler sales and designated the Microgeneration Certification Scheme as the sole certification scheme for the CHMM. DESNZ will proceed with introducing scheme regulations to Parliament to implement these decisions in advance of Year 2, which begins on 1 April 2026.
