Regulation (EU) 2024/573 reshaped the European refrigerant market when it entered into force in March 2024, and the sharpest deadlines are here now. The EU’s updated F-Gas rules cut HFC production quotas to just 31% of the 2015 baseline for the current period and will tighten to 24% in 2027 (EUR-Lex, Regulation 2024/573, Annex VII). For HVAC contractors, facility managers, and equipment specifiers across Europe, this isn’t theoretical policy. It’s a compliance calendar that affects what you can install, what you can service, and what you’ll pay for refrigerant. This guide breaks down the ban dates, GWP limits, refrigerant alternatives, pricing, and safety codes you need to know.
Key Takeaways
What Is Changing Under the EU F-Gas Regulation in 2026?
The EU’s revised F-Gas Regulation (EU) 2024/573 introduced sector-specific bans on new high-GWP equipment, tightened servicing restrictions, and accelerated the HFC quota phasedown from the original 2014 regulation. The most immediate 2026 milestone is the servicing ban on virgin fluorinated gases with a GWP of 2500 or higher for air conditioning systems (Regulation 2024/573, Article 11, 2024). That threshold directly targets R-404A (GWP 3922) and R-507A (GWP 3985), while R-410A (GWP 2088) sits just below it.
The regulation works on two tracks at once. The first is a quota system capping how much virgin HFC producers and importers can place on the EU market each year. Think of it as a shrinking supply ceiling. The second is equipment-level bans listed in Annex IV, which block new equipment above certain GWP limits from specific dates. What catches many contractors off guard is the gap between these tracks: a refrigerant can be banned for new installations years before its servicing ban arrives. So what does that mean for your existing systems?
R-410A is the textbook example. New single split heat pumps using R-410A were blocked from 2025 (GWP 750 limit for systems with less than 3 kg charge), but servicing existing R-410A equipment with virgin gas remains legal because its GWP of 2088 is below the 2026 servicing threshold of 2500. In practice, the quota squeeze is doing the work the ban hasn’t done yet: virgin R-410A prices rose 15 to 25% across many EU markets between 2024 and 2026.
How the EU HFC Quota System Works
The quota runs on a baseline measured in CO₂-equivalent tonnes (not by weight) set at 2015 levels. Each production and import company receives individual allocations. The Annex VII schedule runs: 31% of baseline for 2024 to 2026, dropping to 24% for 2027 to 2029, then a steep drop to just 5% from 2030 onward. That 2030 cliff is what’s driving urgency across the supply chain.
The quota pressure creates a paradox worth understanding. R-410A isn’t technically banned for most servicing, but the economic signal is louder than the regulatory one. When virgin gas costs 30 to 50% more each quota cycle, the financial case for switching to R-32 or R-454B builds on its own. You don’t need a ban date to force a transition when the price does it for you.
What Are the Key F-Gas Deadlines from 2025 to 2030?
Annex IV of Regulation (EU) 2024/573 lists more than a dozen equipment-specific ban dates, but the six deadlines that affect the most HVAC and refrigeration businesses fall between 2025 and 2030. The European Commission published the consolidated timeline in its F-gases guidance on climate-friendly alternatives (2024). Missing even one of these dates can mean unsellable equipment sitting in your warehouse.
The pattern is clear: commercial refrigeration got hit first (2022 for large centralized, 2025 for plug-in), then AC and heat pumps (2025 for small splits, 2027 for broader categories), with a full-market squeeze arriving by 2030. If you’re specifying equipment today, design for the 2027 limits, not the 2026 ones. Why buy a system that will be legal for only 12 more months?
How Do GWP Limits Work by Equipment Type?
The GWP limits under Regulation (EU) 2024/573 are tiered by equipment category and date, which is exactly where confusion enters. A refrigerant legal for one application type can be banned for another. The table below consolidates the limits from Annex IV, and it’s the reference most contractors in the EU work from (EUR-Lex, Annex IV).
| Equipment Type | GWP Limit | Effective Date | What It Means |
|---|---|---|---|
| Multipack centralized (>40 kW) | < 150 | Jan 2022 | Already in force. Only natural or ultra-low-GWP options. |
| Self-contained commercial (plug-in) | < 150 | Jan 2025 | R-290 (propane) dominates this category. |
| Single split AC / HP (<3 kg F-gas) | < 750 | Jan 2025 | R-32 (GWP 675) and R-454B (GWP 466) both pass. |
| Servicing AC systems (virgin gas) | < 2500 | Jan 2026 | Targets R-404A, R-507A. R-410A (2088) just below the line. |
| Split AC ≤12 kW (new equipment) | < 150 | Jan 2027 | Only R-290 or R-32 (with derogation) qualify. |
| Monobloc ≥3 kg (new equipment) | < 150 | Jan 2027 | Pushes larger heat pumps toward R-290 or CO₂ variants. |
| Hermetically sealed systems | < 150 | Jan 2029 | Final tightening for remaining equipment categories. |
How do you know which limit applies to your project? Start with the equipment category, not the refrigerant. The same R-32 that passes the 2025 split limit (GWP 675 is below 750) won’t pass the 2027 limit of 150 for splits under 12 kW. That means R-32 systems installed in 2025 are fully legal, but the same refrigerant in a new system from 2027 depends on charge size and equipment type. Context matters more than the refrigerant name.
One common mistake: the GWP 150 limit for heat pumps from 2025 is often repeated online, but it’s wrong. The 2025 limit of 150 applies to self-contained commercial refrigeration equipment. For single split heat pumps under 3 kg, the 2025 threshold is 750. The GWP 150 limit for broader heat pump and AC categories doesn’t arrive until 2027. Always cross-reference with Annex IV directly, because secondhand summaries tend to mix these up.
Is R-410A Really Banned in the EU After 2026?
R-410A’s GWP of 2088 under IPCC AR4 (the standard used in EU regulation until 2025) sits below the 2500 servicing threshold, which means virgin R-410A is not directly banned for AC servicing by the January 2026 deadline. However, the revised regulation shifted to AR5 GWP values starting January 2025, where R-410A’s GWP is 1924 (IPCC Fifth Assessment Report). Under AR5, the gap to the 2500 line widens further, making R-410A legal for servicing even longer than many sources claim.
The real pressure on R-410A comes from three directions simultaneously. First, the quota phasedown shrinks the pool of available virgin HFC each year, driving up prices. Second, new equipment bans (GWP 750 for splits under 3 kg from 2025, GWP 150 for more categories from 2027) mean manufacturers are shifting production to R-32 and R-454B lines. Third, recycled and reclaimed R-410A supply remains limited because recovery infrastructure is still catching up to demand across much of Europe.
In practice, here’s the exit strategy most EU contractors are following: continue servicing existing R-410A systems with recovered or reclaimed gas, but specify R-32 or R-454B for every new installation. Don’t plan any new R-410A projects. The day you can’t find affordable virgin gas for a top-up is unpredictable, but it’s getting closer every quota cycle. If you’re unsure what refrigerant your existing system uses, our guide to identifying your HVAC refrigerant type walks through the nameplate and cylinder identification process.
R-32 vs R-454B in Europe: Which Refrigerant Should You Choose?
R-32 commands roughly 55% of new split AC and heat pump installations across Europe in 2025, far ahead of R-454B’s estimated 10% share (Eurovent/EHPA market estimates, 2025). The European market flipped the opposite way from North America, where R-454B leads. The reason is straightforward: Daikin introduced R-32 systems in Europe starting in 2014 and built a decade-long head start in supply chains, installer training, and consumer awareness. Mitsubishi Electric, Panasonic, and Toshiba followed with R-32 product lines across residential and light commercial segments.
But which one should you specify for a new install? Both are A2L classified (mildly flammable, lower toxicity), and both clear the 2025 GWP 750 limit for small splits. The technical differences that matter in practice come down to four factors.
GWP: R-454B wins at 466 vs R-32’s 675. That gap matters for the 2027 GWP 150 threshold: neither refrigerant passes it, but R-454B gives more headroom for future regulation changes. Performance: R-32 delivers roughly 5 to 8% higher cooling capacity per kilogram because it’s a pure compound with no temperature glide. R-454B, as a blend of 68.9% R-32 and 31.1% R-1234yf, has a small glide of about 1.5 K. Cost: R-32 trades at 25 to 40 EUR per kilogram in the EU, compared to R-454B at 40 to 60 EUR per kilogram. R-32’s price advantage comes from being a single molecule that’s simpler to manufacture and easier to reclaim. Recyclability: R-32 is a pure substance, so reclamation is straightforward. R-454B requires blend separation, which adds cost and complexity.
For most European residential and light commercial projects, R-32 is the pragmatic pick: it’s cheaper, performs better per kilogram, easier to reclaim, and the supply chain is mature. R-454B makes more strategic sense when the specification demands the lowest possible GWP or when designing for North American export markets where OEM adoption is higher. For a deeper look at R-454B specifically, see our complete R-454B refrigerant guide.
Natural Refrigerants: R-290, R-744, and R-717 in the EU
Natural refrigerants have GWPs at or near zero and fall outside HFC quota restrictions entirely, which makes them the only truly long-term solution under any foreseeable tightening of EU regulation. More than 111,650 European supermarkets now run transcritical CO₂ systems (shecco/ATMOsphere data, 2025), and R-290 (propane) is standard in new self-contained commercial cases. Each natural refrigerant owns a specific application where its strengths outweigh its complications.
R-290 (Propane): Commercial Refrigeration and Small Heat Pumps
R-290 is refrigerant-grade propane with a GWP of 3 and an A3 (highly flammable) safety classification. The charge limit increase from 150 grams to 500 grams under IEC 60335-2-89:2022 opened up most reach-in coolers, freezers, vending machines, and bottle coolers to R-290 designs. Systems must be hermetically sealed with brazed joints, and spark-proof electrical components are mandatory. Retailers like ALDI, Lidl, and REWE across Europe have standardized on R-290 for new plug-in cases. The systems are self-contained: no field-installed line sets, no on-site brazing.
R-744 (CO₂): Supermarket Transcritical Systems
R-744 (carbon dioxide) has a GWP of 1, is non-flammable, and is non-toxic. It runs at operating pressures of around 74 bar on the suction side and up to 100 bar at the gas cooler outlet in transcritical mode. That pressure profile demands specific compressors and thicker-wall tubing, but the systems deliver excellent heat reclaim capabilities, which is why they’ve become the default for European supermarket refrigeration. The 111,650+ installed base includes Carrefour, Tesco, and Ahold Delhaize. Cold-climate performance is strong, and booster configurations now work well in southern European climates too.
R-717 (Ammonia): Industrial Cold Storage
R-717 (ammonia) has a GWP of 0 and delivers the highest energy efficiency of any common refrigerant. Its B2L toxicity classification (toxic at concentrations above 25 ppm) limits it to industrial settings with dedicated machine rooms, proper ventilation, and trained operators. In Europe, ammonia runs the majority of large cold storage warehouses, food processing plants, and ice rinks. The Seveso III Directive applies to sites with more than 50 tonnes of ammonia inventory, and ATEX zoning is required around equipment. Despite these requirements, ammonia’s zero climate impact and unbeatable efficiency keep it as the industrial benchmark.
What Do Low-GWP Refrigerants Cost in Europe?
Refrigerant pricing in Europe in 2026 is driven more by the HFC quota than by raw material costs. The EU quota phasedown from 100% (2015 baseline) to 31% (2024 to 2026) has already pushed virgin HFC prices up significantly, and the next step to 24% in 2027 will tighten supply further. R-32 trades at roughly 25 to 40 EUR per kilogram, while R-454B sits at 40 to 60 EUR per kilogram across EU distributors (mid-2026 wholesale pricing).
What happens to pricing when the quota drops that low? You’ll find that R-410A, despite not being banned for servicing, has become the most expensive option in practice. As production shifts to lower-GWP alternatives, virgin R-410A supply shrinks. Reclaimed R-410A fills some of the gap, but reclamation infrastructure varies widely across EU member states. Germany and the Netherlands have relatively mature recovery networks, while southern and eastern European markets lag behind.
The tooling investment for A2L refrigerants is a one-time cost that contractors tend to overestimate. A2L-rated recovery machines, vacuum pumps, manifold sets, and leak detectors typically add 1,500 to 3,000 EUR to a shop’s equipment budget. Nitrogen kits, brazing tools, and most existing gauges still work. The bigger cost is training: updating F-gas certification to cover A2L handling procedures takes 1 to 2 days per technician. Once you’ve made that switch, you’re covered for both R-32 and R-454B since they share the same safety classification.
What Safety Codes Apply to A2L Refrigerants in Europe?
EN 378 (Safety and Environmental Requirements for Refrigerating Systems and Heat Pumps) is the primary safety standard for refrigeration equipment in Europe, and its 2024 revision expanded the framework for A2L refrigerants with updated charge limits and room-size calculations. Unlike the US approach, which relies on ASHRAE 15 and UL 60335-2-40, Europe uses EN 378 as a harmonized standard under the Machinery Directive, giving it direct regulatory weight across all EU member states.
EN 378 Charge Limits for A2L Refrigerants
EN 378 calculates maximum charge limits based on the room volume, ventilation type, and refrigerant’s Lower Flammability Limit (LFL). For R-32 (LFL 14.4% by volume), the practical charge limit in a typical 20 m³ occupied space with natural ventilation is approximately 1.84 kg. R-454B (LFL 11.8%) has a lower per-room limit because of its lower LFL. These limits directly influence system design: a small bedroom split can hold less refrigerant than a large open-plan commercial space. Manufacturers design around these constraints, which is why you’ll see different charge sizes in different product lines from the same brand.
F-Gas Certification Across EU Member States
Every EU member state requires company certification and personal technician certification for anyone handling F-gases, but the administering bodies differ. In the Netherlands, Stichting F-Gassen Nederland manages certification. Germany requires a Sachkundenachweis (proof of competence) administered through the IHK (Industrie- und Handelskammer) under the ChemKlimaschutzV (Chemical Climate Protection Ordinance). France uses the attestation de capacité system under Décret n° 2007-737.
All certifications now must cover A2L handling, which means additional training on flammability-rated tools, leak detection at lower concentration thresholds, and ventilation requirements during service. If your technicians haven’t updated their certification to include A2L procedures, that’s the first item on your compliance checklist. The good news: A2L training is a one-time update, and it covers both R-32 and R-454B since they share the same safety class. For a broader look at what certification requirements mean for refrigerant selection, see our Dutch refrigerant selection guide.
What Happens After 2030? The Road to Near-Zero GWP
The 2030 quota target of 5% of the 2015 baseline is the steepest single reduction step in the entire phasedown schedule, and it aligns with the Kigali Amendment to the Montreal Protocol, which commits developed countries to an 85% HFC reduction by 2036 (UNEP Ozone Secretariat, Kigali Amendment). The EU moved faster than Kigali required, setting up a scenario where European industry leads the global transition.
What does a 5% quota world look like? Virgin high-GWP refrigerant becomes a specialty item, priced accordingly. Reclaimed and recycled refrigerant fills most of the servicing demand for legacy equipment. New equipment runs almost entirely on sub-150 GWP options: R-32 where charge limits allow it, R-290 for self-contained applications, R-744 for commercial refrigeration, and R-717 for industrial settings. The transitional blends like R-407F and R-448A, which were useful bridge solutions, will face the same scarcity pressure as R-410A because their GWPs (1824 and 1387 respectively) consume disproportionate quota. For more on R-407F’s specific role as a transitional option, see our R-407F refrigerant guide.
The industry direction is clear. Every new project specified today should assume a sub-150 GWP world is coming within 5 years. Don’t design systems around refrigerants that will be economically or physically unavailable by 2030. For the US perspective on this same transition, our Low-GWP Refrigerant Guide for the US market covers the parallel EPA framework.
Frequently Asked Questions
Can I use recycled R-410A after 2026 in the EU?
Yes. R-410A’s GWP of 2088 (AR4) falls below the 2500 servicing threshold, so even virgin R-410A remains legal for AC servicing after January 2026. Recovered and reclaimed gas faces no date restriction at all under Regulation (EU) 2024/573 Article 8. The practical constraint is supply: the quota phasedown makes virgin HFCs scarcer each year, pushing prices up and making recycled stock the more cost-effective option.
What are the key F-gas exemptions for 2026 in the EU?
The main exemptions cover recycled and reclaimed refrigerants (no date restriction), military and defense applications, semiconductor manufacturing, and certain medical devices. For HVAC, the most relevant exemption is that servicing bans apply only to virgin gas, not recovered stock. Equipment already installed can continue operating. The ban restricts what you can buy to refill a system, not the system itself.
Does the 2026 regulation ban existing R-410A systems?
No. Regulation (EU) 2024/573 does not require removing or replacing installed equipment. It restricts placing new high-GWP equipment on the market and limits servicing with virgin gas above certain GWP levels. Your R-410A system can run until end of life. The transition gets forced only when you need a refrigerant top-up and virgin gas is no longer available or affordable at that point.
What F-gas certification do HVAC contractors need in the EU?
Each member state requires company certification and personal technician certification. The Netherlands uses Stichting F-Gassen, Germany requires a Sachkundenachweis through the IHK under the ChemKlimaschutzV, and France administers the attestation de capacité. All certifications must now cover A2L refrigerant handling, which means additional training on flammability-rated tools and leak detection procedures.
What is the GWP limit for new heat pumps from 2025?
For single split heat pump systems containing less than 3 kg of F-gas, the GWP limit from January 2025 is 750, not 150 as frequently misreported. The 150 threshold applies to self-contained commercial refrigeration equipment from 2025. Larger heat pump configurations and monobloc systems transition to GWP 150 limits by 2027. Always cross-check Annex IV of Regulation (EU) 2024/573 for your specific equipment type.
How much does R-32 cost compared to R-454B in Europe?
In mid-2026, R-32 trades at roughly 25 to 40 EUR per kilogram while R-454B sits at 40 to 60 EUR per kilogram across EU wholesale markets. The price gap reflects R-454B’s more complex manufacturing (it blends R-32 with R-1234yf) and lower production volume in Europe. R-32’s single-component nature makes it cheaper to produce, transport, and reclaim.
Can I convert an R-410A system to R-32?
Generally no. R-410A and R-32 operate at different pressures, and R-32’s mild flammability (A2L classification) requires components rated for flammable refrigerants. A straight refrigerant swap would violate EN 378 safety requirements. In practice, the most reliable path is replacing the outdoor unit (and often the indoor unit) with R-32 rated equipment. Some manufacturers offer dedicated R-32 conversion kits, but a full system replacement is more common.
When does the EU HFC quota reach its lowest point?
The final step drops to 5% of the 2015 baseline from January 1, 2030, under Annex VII of Regulation (EU) 2024/573. That represents a 95% reduction in available virgin HFC supply. Before that, the quota moves from 31% (2024 to 2026) to 24% (2027 to 2029). The 2030 target aligns with the Kigali Amendment to the Montreal Protocol and signals a near-complete phaseout of virgin high-GWP refrigerants.
The Bottom Line on EU F-Gas Compliance
The 2026 F-Gas changes aren’t one deadline. They’re a cascade: commercial refrigeration bans arrived in 2022 and 2025, AC servicing restrictions land in 2026, broader heat pump and split system bans follow in 2027, and by 2030 the quota drops to 5%. Treat this as a three-step plan. First, update your F-gas certification to cover A2L refrigerants. Second, specify R-32 or R-454B for every new installation and R-290 for self-contained commercial cases. Third, plan your R-410A exit: start recovering gas from decommissioned systems now, because reclaimed R-410A will be the only practical option for servicing legacy equipment within a few years.
