The phasedown step scheduled for 1 January 2027 will therefore remain as set out in Annex 5 of the current F-gas Regulation. DEFRA said this approach is intended to provide certainty for businesses planning equipment, refrigerant supply and compliance strategies for the next quota reduction.

The department said its decision follows an assessment of 137 consultation responses, which indicated that further work is needed before reforms can be finalised.

Officials stressed that the government remains committed to delivering “ambitious reform” of the HFC phasedown. A report summarising consultation feedback, along with an outline of proposed next steps, is expected later in the year.
