UK Refrigerant Gas Regulations 2025: What You Need to Know

Before purchasing refrigerant gas in the UK, you must understand the F-Gas Regulation (EU 517/2014, retained in UK law post-Brexit). The key rules are:

F-Gas certification is mandatory — you must hold a valid F-Gas qualification to purchase most refrigerants including R410A, R32, R407C, R404A and R134a.
High-GWP refrigerants are being phased down — R404A (GWP 3,922) and R507A are restricted in new equipment. Alternatives like R449A are preferred for new installations.
R22 is banned — HCFC refrigerants including R22 are fully prohibited in the UK. Do not purchase or use R22.
Record keeping is required — systems containing 3kg or more of fluorinated gas must be checked for leaks regularly.
R1234yf is lower restriction — this ultra-low-GWP (4) automotive refrigerant has fewer purchase restrictions but still requires competent handling.

Use: Split AC systems, heat pumps, VRF systems
Available sizes: 5kg, 9kg, 11.3kg cylinders
F-Gas certification required: Yes
Replacing: R410A in new systems from 2025 onwards

Frequently Asked Questions: Buying Refrigerant Gas in the UK

Do I need F-Gas certification to buy refrigerant gas in the UK?

Yes. To purchase most HFC refrigerants in the UK — including R32, R410A, R407C, R404A and R134a — you must hold a valid F-Gas qualification under UK F-Gas Regulation. Individuals without certification cannot legally purchase these gases for professional use. Refrigerant Gas Supplies Ltd verifies certification before processing commercial orders.

Is R410A being phased out in the UK?

Yes — R410A is being phased down under UK F-Gas regulations due to its high GWP of 2,088. It is no longer permitted in many new split AC systems and manufacturers are switching to R32 (GWP 675). However, R410A remains legal and available for servicing and maintaining existing installations for the foreseeable future. You can still buy R410A for maintenance from Refrigerant Gas Supplies Ltd.

Which refrigerant should I use for a new air conditioning installation in the UK?

For any new AC installation in the UK in 2025, R32 is the recommended choice. It is the standard refrigerant in new systems from Daikin, Mitsubishi, Panasonic and LG, offering a GWP 68% lower than R410A and excellent energy efficiency.

Can I buy refrigerant gas online in the UK?

Yes — Refrigerant Gas Supplies Ltd sells refrigerant gas online with next-day UK delivery. F-Gas certification verification is required for regulated refrigerants. We supply trade quantities to HVAC engineers, refrigeration technicians, facilities management companies and automotive workshops across the UK.

How much does refrigerant gas cost in the UK in 2025?

Typical 2025 UK trade prices: R32 9kg cylinder £60–90; R410A 11.3kg cylinder £55–85; R404A 10kg £80–130; R134a 12kg £50–75; R1234yf £25–45 per kilogram. Contact us for current bulk pricing.

What refrigerant does my car use?

Cars manufactured from January 2017 onwards use R1234yf. Cars made before 2017 typically use R134a. Check the label on the AC compressor under the bonnet or consult your vehicle manual. Do not mix R134a and R1234yf — they are incompatible.

What is the difference between R32 and R410A?

R32 has a much lower GWP (675 vs 2,088), better energy efficiency, and is the future standard for new AC systems in the UK. R410A is still dominant in existing installations. R32 is mildly flammable (A2L classification) requiring specific handling precautions, while R410A is non-flammable. See our full refrigerant comparison guide →

Is R22 refrigerant still available to buy in the UK?

No. R22 has been completely banned in the UK since 1 January 2015 for both new equipment and servicing. It is illegal to purchase or use R22. Equipment using R22 must be retrofitted with an approved alternative (such as R407C or R422D) or replaced entirely.

How do I dispose of old refrigerant gas in the UK?

Refrigerant gas must never be vented to atmosphere — this is illegal and carries significant fines. Used refrigerant must be recovered using certified equipment by a qualified F-Gas technician and returned to an approved reclaim facility. Contact Refrigerant Gas Supplies Ltd for guidance on approved recovery routes.
