UK F-Gas Regulation 2025 Update: What HVAC and Refrigeration Engineers Need to Know
The UK F-Gas Regulation has continued to evolve since Brexit, with an independent phase-down schedule and ongoing enforcement action by the Environment Agency. This guide summarises the key regulatory changes affecting UK refrigerant engineers and operators in 2024–2025.
UK F-Gas Regulation: The Post-Brexit Framework
After the UK left the EU, the existing EU F-Gas Regulation was retained and amended by UK Statutory Instrument 2022 No. 1013. The UK now operates its own HFC quota system, administered by the Environment Agency. This means UK businesses that previously operated under the EU quota system must comply with the separate UK regime. Key points:
- UK quota allocations are calculated in CO2-equivalent tonnes
- Businesses placing HFCs on the UK market above a threshold need quota authorisation
- UK end-users (HVAC companies, refrigeration contractors) buy refrigerant from quota holders — they do not hold quota themselves
- The Environment Agency enforces compliance and can issue civil penalties
2025 Phase-Down Status: Which Refrigerants Are Most Affected?
The UK phase-down progressively reduces the total quantity of HFCs (measured in CO2e) that can be placed on the UK market each year. High-GWP gases are disproportionately expensive to place on the market under the quota system:
- R404A (GWP 3,922): Most restricted. 1 tonne uses 3.9× more quota than 1 tonne of R32.
- R410A (GWP 2,088): Heavily restricted. Price rising each year.
- R407C (GWP 1,774): Significantly restricted.
- R32 (GWP 675): Much less quota impact. Prices more stable.
- R1234yf/R1234ze (GWP <5): Essentially unaffected by HFC quotas.
Key 2025 Compliance Obligations
- F-Gas certification required to purchase all regulated HFC refrigerants
- Leak check schedules and equipment records must be maintained
- Disposable refrigerant cylinders remain banned
- All recovered refrigerant must be reclaimed or recycled — no release to atmosphere
- New equipment for stationary AC must not use refrigerants with GWP >750 (from 2025 in EU — UK monitoring equivalent measures)
All refrigerant sold by Refrigerant Gas Supplies Ltd is F-Gas quota-compliant. R32, R410A, R1234yf — next-day UK delivery.
Frequently Asked Questions
What changed in UK F-Gas regulation in 2024–2025?
Continued HFC quota tightening under SI 2022 No. 1013. Quota reductions increase costs for high-GWP gases like R404A and R410A. Disposable cylinder ban and F-Gas certification requirements unchanged. UK operates independently of the EU’s new 2024 F-Gas Regulation.
Does Brexit mean UK F-Gas rules differ from EU rules?
Yes. UK operates its own F-Gas Regulation (amended 2022) enforced by the Environment Agency. EU introduced new regulation EU 2024/573. UK engineers trading in Europe must comply with both regimes separately.
Which refrigerants are most affected by UK F-Gas phase-down?
R404A, R507A and R410A are most heavily quota-restricted due to high GWP. R32 (GWP 675) and R1234yf (GWP 4) are minimally affected.
