Fluorinated Gases: Regulation

Between 5 November and 17 December 2025, Defra consulted on proposals to reform the phasedown of hydrofluorocarbons (HFCs) under the F-gas Regulation. Following consideration of the 137 responses received, Defra confirmed on 15 May 2026 that further work is needed on changes to the HFC phasedown, and that we will not legislate in 2026 to change the phasedown steps from 1 January 2027. For 2027, this means that the relevant HFC phasedown step in the F gas Regulation will continue to apply. Defra remains committed to introducing ambitious reform to the HFC phasedown and intend to publish a report summarising responses and an outline of next steps later this year.

To mitigate the impacts of rising active cooling demand, in the UK and across the world, the UK has played a leading role in the development of the Global Cooling Pledge working alongside international partners. The pledge has now been backed by 75 countries and 250 cities and organisations, highlighting the global recognition of the need for action. As a signatory to the pledge, the UK is committed to pursuing sustainable cooling solutions to meet future cooling needs. The UK is on track to meet the sixteen commitments of the Pledge, including publishing the UK Cooling Outlook in 2026 which will consolidate evidence, identify opportunities and future evidence needs to pursue sustainable and efficient cooling and refrigeration.
