The UK refrigerant gas market covers everything from domestic heat pump and AC refrigerants like R32, to commercial refrigeration gases like R404A and R449A, automotive AC refrigerants R134a and R1234yf, and emerging low-GWP alternatives. This complete UK refrigerant guide brings together the essential information for HVAC engineers, refrigeration contractors and building managers navigating the market in 2025 and beyond.
The Most Important Refrigerants for UK HVAC in 2025
- R32: Standard for new split AC and heat pumps. GWP 675, A2L, replacing R410A in new equipment.
- R410A: Widely used in existing installations. GWP 2,088. Banned in new equipment from 2025. Service supply continues.
- R404A: Legacy commercial refrigeration standard. GWP 3,922. Banned in new equipment. R449A is the retrofit replacement.
- R134a: Automotive AC (pre-2017 vehicles) and commercial chillers. GWP 1,430.
- R1234yf: Automotive AC for all vehicles from January 2017. GWP 4.
- R407C: Legacy R22 replacement in older commercial AC systems. GWP 1,774.
F-Gas Regulation: The Framework for 2025 and Beyond
UK F-Gas Regulation progressively reduces the total quantity of HFC refrigerant permitted on the market through quota reductions reaching 21% of baseline by 2030. Equipment bans: R410A banned in new stationary AC from January 2025; R404A banned in new commercial refrigeration from 2022. For UK HVAC contractors this means: R32 for all new AC and heat pump installations, R449A for commercial cold room retrofits, and continuing price rises for R410A and R404A service stock as quotas tighten.
Buying Refrigerant Legally in the UK
All HFC refrigerant purchases require valid F-Gas certification (REFCOM Category I or II). Suppliers must verify certification before selling. F-Gas documentation must accompany every delivery. Venting refrigerant to atmosphere is illegal and subject to unlimited fines. All professional refrigerant comes in refillable cylinders — disposable cans over 600g are banned under UK law.
2025 Pricing Outlook
Refrigerant prices are on a predictable upward trajectory for high-GWP gases as F-Gas quotas tighten through 2027. R404A and R410A will continue to increase year-on-year. R32 faces less quota pressure due to lower GWP. Plan purchases ahead of peak season and consider transitioning customers from R410A and R404A equipment where replacement is due.
