R134a vs R1234yf Cost Comparison UK 2025: Fleet Operators and Garages

R134a vs R1234yf Cost Comparison UK 2025

R1234yf costs 4–6× more per kg than R134a, making it one of the most significant cost differences in automotive AC servicing. Understanding this gap — and what drives it — helps UK garages and fleet operators budget accurately.

Price Per Kg UK 2025

• R134a: ~£7–£12/kg. 13.6 kg cylinder ~£100–£160
• R1234yf: ~£40–£65/kg. 5 kg cylinder ~£200–£300

The price gap is driven by R1234yf’s complex HFO synthesis and limited global producers — not by F-Gas quotas (R1234yf has GWP 4, essentially exempt from quota restrictions).

Cost Per Vehicle Recharge

• 500 g R134a: ~£3.75–£6 refrigerant cost to garage
• 500 g R1234yf: ~£20–£32 refrigerant cost to garage

Add the higher capital cost of R1234yf AC service machines (£3,000–£6,000 vs £1,500–£2,500 for R134a) and garages typically charge £50–£100 more for R1234yf recharges.

Tips for Fleet Operators

• Source R1234yf directly from UK F-Gas supplier in bulk — lower per-kg cost vs buying through garages
• Maintain separate stock and machines for R134a and R1234yf vehicles
• Confirm refrigerant type before booking service

Frequently Asked Questions

Why is R1234yf so much more expensive than R134a?

Complex HFO synthesis and fewer global producers. Not subject to HFC quotas (GWP 4) but manufacturing cost keeps it 4–6× more expensive per kg.

Will R1234yf prices come down?

Gradually as global production scales up. Unlikely to reach R134a price levels but continued decline expected through 2025–2028.

Can R1234yf be reclaimed and reused?

Yes — recovered using dedicated service machines and reclaimed to specification. Commercially important given the high per-kg cost.
