Two changes took effect in Europe on 1 January 2026 that most buyers outside the EU have not priced in yet, and a third landed in Singapore three weeks ago. None of them made big headlines. All three will show up in specifications and service invoices this year.
1. The EU started charging for HFC quota
Since 1 January 2026, every tonne of CO2-equivalent HFC quota allocated through the EU F-gas Portal carries a €3 fee. It was originally scheduled for 2025 and slipped by a year. The fee applies to HFCs and HFC/HFO blends; pure HFOs and reclaimed refrigerant stay outside the quota system.
The €3 is not the story. The quota is.
- 2023: 82.3 Mt CO2e
- 2025–2026: 42.9 Mt CO2e (current period)
- 2027–2029: 21.7 Mt CO2e
- 2030–2032: 9.1 Mt CO2e
- 2050: 0
That is roughly a 48% cut between 2023 and the period we are in now, and another halving in 2027. For anyone maintaining R410A plant in Europe, supply rather than demand will set the price of top-up gas for the rest of the decade.
2. The servicing ban is narrower than the headlines suggest
Also from 1 January 2026: Annex I F-gases with a GWP of 2,500 or above may not be used to service air-conditioning and heat pump equipment, subject to the exceptions in Article 13 of Regulation (EU) 2024/573.
R410A has a GWP of 2,088. It sits below that line, so the widely repeated claim that R410A machines can no longer be serviced is wrong. What is true is that R410A is being squeezed from the other side: less of it on the market every year, and equipment bans written at far lower GWP thresholds (150 for most self-contained and split systems, phased in from 2027).
For a mixed fleet, the useful question is not whether R410A is banned. It is what a kilogram of it will cost your maintenance budget in 2029.
3. Leak checks: the cheapest compliance lever is a fixed detector
The leak-check bands in Regulation (EU) 2024/573 are calculated on CO2-equivalent charge, not on kilograms of gas:
| Charge (Annex I) | Without leak detection | With leak detection |
|---|---|---|
| Below 5 t CO2e | Normally not required | Normally not required |
| 5 to below 50 t CO2e | Every 12 months | Every 24 months |
| 50 to below 500 t CO2e | Every 6 months | Every 12 months |
| 500 t CO2e and above | Every 3 months | Every 6 months (detection mandatory) |
Five tonnes of CO2 equivalent is a low bar. German federal environment agency guidance puts it at about 2.40 kg of R410A or 7.41 kg of R32. A single mid-size packaged unit can clear it.
So the arithmetic on a fixed leak detection system is simple: on a machine in the 5–50 t band, it halves the statutory inspection frequency — five fewer paid inspections over ten years, before counting the refrigerant you stop losing. Below 5 t, checks are not mandatory at all, but the general duty to prevent emissions still applies and a known leak still has to be repaired.
Two details that get missed: records have to be kept for at least five years, and after a repair the effectiveness check has to happen after at least 24 operating hours and within one month.
4. UK: a £200,000 ceiling and a specific exemption list
Great Britain has clarified its 2025 prohibition on single split systems containing under 3 kg of F-gas with a GWP of 750 or higher — R407C and R410A fall inside it. The exemptions are narrow and worth reading literally: equipment used solely for product cooling, air-to-water splits, and units installed on marine craft.
Stock already on the GB market can still be sold where the business can show it entered the market before 1 January 2025. Civil penalties run up to £200,000. As in the EU, equipment that was legally installed does not have to be removed.
5. Singapore, 25 August: A2L has become a fire-safety line item
At a consultant and contractor seminar in Singapore on 25 August, Midea Building Technologies walked through what Green Mark 2021 and Super Low Energy compliance now demand of chilled-water plants. The refrigerant part is the one to watch.
R1234ze is a Class 2L mildly flammable refrigerant. In Singapore its use falls under the SCDF’s Petroleum and Flammable Materials regulations, so leak detection, forced-air exhaust and fire-rated enclosures have to be engineered as one package rather than bolted on afterwards. Speakers were explicit that refrigerant selection and machine-room design can no longer be separate decisions.
If you supply air-side equipment into A2L projects, this is the point at which exhaust dampers and their actuators stop being commodity hardware. The ventilation sequence has to be documented, proven and interlocked with gas detection — and it has to survive a fire authority review.
6. Europe is drifting to R290, North America to A2L blends
The two markets are not converging. European manufacturers are putting weight behind propane (R290, GWP 0.02 against 771 for R32), partly because it avoids the PFAS questions hanging over HFOs. North American producers are moving to A2L synthetics such as R32 and R454B.
Natural refrigerants were about 8% of European heat pump sales in 2022, and R290 equipment typically carries a 10–15% price premium over legacy HFC machines — a premium buyers are increasingly willing to pay rather than gamble on future HFC servicing costs.
There is a component consequence. R290’s flammability limits charge size, which pushes designers toward more circuits, more isolation valves and more sensing points for the same capacity. Smaller charges, more control points.
7. Where the volume actually is: the Gulf, and retrofit work
Regulation is reshaping Europe. Volume growth is elsewhere.
- GCC district cooling is forecast to grow from about $8.4 billion in 2025 to $22.1 billion by 2034, around 11.3% a year. Tabreed reports more than 1.4 million refrigeration tons installed; Empower serves over 120,000 customer units in Dubai.
- District cooling in the Gulf runs at 0.55–0.75 kW per refrigeration ton against 1.1–1.4 kW/ton for split systems — a 35–50% difference in energy per ton-hour, which is why regulators keep mandating it.
- In the UAE chilled-water market, the data centre segment is growing fastest at an estimated 12–18% a year, and replacement and retrofit work is estimated at 30–35% of annual equipment volume. Components — pumps, heat exchangers, control valves, pipework — are put at 25–30% of annual market value, with consumables and replacement parts including control sensors at 10–15%.
- NEOM alone is estimated to need around 640,000 refrigeration tons at full build-out, with additions above 200,000 RT a year through the 2027–2031 construction peak.
On the supplier side, Haier’s large-commercial HVAC business reported first-half 2026 results worth noting: number one in magnetic-bearing chillers, with centrifugal shipments up more than 30% year on year and air-cooled screw close to double — while overall industry shipment value contracted. Its AI-driven VRF line is put above 35% market share, and the company led the 2026 AI VRF technology white paper that effectively defines the category.
What this changes for buyers and specifiers
- Do the CO2e calculation on your own fleet. Charge in kg × GWP ÷ 1,000. Anything at or above 5 t CO2e enters periodic leak checks, and a fixed detection system halves the frequency.
- Ask for the refrigerant and its GWP at quotation stage, not at handover. The relevant dates are different per market: 2027 and 2029 are the two that matter most for equipment at or under 12 kW in the EU.
- On A2L projects, settle the fire authority question early. Machine-room exhaust, gas detection and the damper sequence behind them belong in the specification, not in a site instruction.
- Watch retrofit, not just new build. With replacement work at 30–35% of annual volume in markets like the UAE, valves, actuators and sensors are usually the first items a retrofit touches.
- Keep the paperwork. Five-year record retention, certified technicians, repair verification within a month. It is the least interesting part of compliance and the part that gets audited.
We build thermostats, valves, damper actuators and sensors for exactly this kind of work — if you are specifying an A2L machine room or a retrofit package, send us the sequence of operations and we will tell you what we can supply off the shelf.
