UK F-Gas phase-down timeline
Where the wider phase-down stands.
- 2015
R-22 servicing ban
No virgin or reclaimed HCFCs for servicing. The original ozone phase-out completes.
- 2020
High-GWP service ban
Virgin F-Gas with GWP of 2,500 or more banned for refrigeration of 40 tCO₂e or more — hits R-404A / R-507A.
- Jan 2025
New single-split ban
New single-split AC systems containing under 3 kg of F-gas cannot use refrigerants of 750 GWP or more (retained EU 517/2014, Annex III) — rules out R-410A and R-407C.
- 2030
Quota squeeze
The HFC quota drops to about 21% of the 2015 baseline and the reclaimed/recycled exemption for GWP 2,500+ servicing ends — R-404A / R-507A become effectively unavailable.
- 2032
Monobloc ban (EU)
EU Regulation 2024/573 bans F-gases in new self-contained / monobloc AC and heat pumps up to 12 kW. GB retains EU 517/2014 and has not adopted this step — DEFRA consulted on GB reform (closed Dec 2025), response due 2026.
- 2035
Split ban (EU)
EU Regulation 2024/573 bans F-gases in new split AC and heat pumps up to 12 kW. Not yet GB law — GB still follows retained EU 517/2014 pending the delayed HFC phase-down reform.
