The government has confirmed that the launch of the Clean Heat Market Mechanism (CHMM) has been delayed, after months of speculation around the scheme. The Department for Energy Security and Net Zero (DESNZ) has announced a one-year delay to the scheme with just weeks to go before the so-called “boiler tax” was due to come into force. Instead, the scheme has been postponed by one year to April 2025, with industry experts warning that the move puts the government’s heat pump installation targets in “jeopardy”.
