R1234yf Prices in the UK — What to Expect in 2025
R1234yf remains one of the more expensive refrigerants available in the UK, primarily because it is manufactured by a small number of producers (Honeywell and Chemours dominate global supply) and demand from the automotive sector continues to grow as post-2017 vehicles make up an ever-larger share of the UK car parc.
Typical R1234yf Price Ranges (2025)
As a guide, UK trade prices for R1234yf in 2025 typically fall in the following ranges:
- 250g/350g cans (consumer/garage top-up): High per-kg cost, convenience premium
- 1 kg cylinders: Available from specialist suppliers
- 5 kg cylinders: Best value per kg for professional workshops
Our R1234yf 5 kg cylinders offer the best value for certified garages, mobile AC technicians and fleet operators needing regular supply.
What Drives R1234yf Prices?
- Limited manufacturer base: Global supply is dominated by Honeywell and Chemours
- Growing demand: Every post-2017 new car requires R1234yf — demand grows yearly
- Transport and storage: A2L classification adds handling cost
- Import dynamics: Post-Brexit supply chain adjustments affect UK pricing
R1234yf vs R134a: Is the Price Difference Worth It?
R1234yf costs significantly more per kilogram than R134a. However, automotive AC systems using R1234yf are factory-sealed with specific charge weights, and using the correct refrigerant is both a legal and technical requirement — substituting R134a into an R1234yf system is illegal and will damage the vehicle.
