Heat pumps and split air conditioning: every Annex IV ban date

Annex IV does not give air conditioning and heat pumps a single date. It gives two separate tables: one for self-contained and monobloc equipment, one for split systems. Every row has its own capacity band, its own GWP limit and its own safety exception. This page lays them out exactly as the Regulation writes them.

Short answer

For an installer, Annex IV reads in three steps. First decide whether the equipment is self-contained (point 8) or split (point 9). Then find the rated capacity band. Only then compare the GWP of the refrigerant with the limit in that row.

  • Single split systems containing less than 3 kg of Annex I gases can no longer be placed on the market from 1 January 2025 if they use Annex I gases with a GWP of 750 or more — Annex IV, point 9(a). That row has no safety exception.
  • Split systems up to and including 12 kW lose gases with a GWP of 150 or more on 1 January 2027 if they are air-to-water and on 1 January 2029 if they are air-to-air; every fluorinated greenhouse gas goes on 1 January 2035.
  • Split systems above 12 kW lose gases with a GWP of 750 or more on 1 January 2029 and gases with a GWP of 150 or more on 1 January 2033.
  • Self-contained and monobloc equipment up to and including 12 kW stops on 1 January 2027 for a GWP of 150 or more, with a fallback limit of 750 where safety requirements do not allow less.

The prohibition bites on placing on the market, not on use. A unit lawfully placed on the market before the date stays lawful to run and to service, within the limits of Article 13.

What this page does not contain

No prices, no availability, no product recommendations, no delivery times. No national penalties and no dangerous-goods figures either. The choice between R-32 and R-410A is handled in R-32 or R-410A, and the general list of dates in the F-gas ban timetable.

What placing on the market actually means

Article 3, point (6) defines placing on the market as customs release for free circulation in the Union, or the supplying or making available to another person within the Union for the first time, for payment or free of charge, or the use of substances produced or equipment manufactured for own use. It is not the installation date, not the invoice date to the end customer and not the commissioning date.

Article 11(1), first subparagraph prohibits the placing on the market of the products and equipment listed in Annex IV, including parts thereof, with an exemption for military equipment, from the date specified in that Annex, differentiating where applicable according to the type or global warming potential of the gas contained.

The second subparagraph keeps spare parts alive: the placing on the market of parts required for repair and servicing of existing equipment listed in Annex IV is allowed provided the repair or servicing does not result in an increase in the capacity of the equipment, an increase in the amount of fluorinated greenhouse gas contained in it, or a change in the type of gas used that would lead to an increase of the GWP.

The fifth subparagraph is the one that catches distributors: one year following the individual dates listed in Annex IV, the subsequent supply or making available to another person in the Union of products lawfully placed on the market before the date shall be allowed only if evidence is provided that the product was placed lawfully on the market before that date. The burden of proof moves to whoever sells the stock.

Two further valves exist. Article 11(2): the prohibition does not apply to equipment for which it has been established, pursuant to ecodesign requirements adopted under Directive 2009/125/EC, that its lifecycle CO2 equivalent emissions would be lower than those of equivalent equipment meeting those requirements. Article 11(5): following a substantiated request by a competent authority, the Commission may exceptionally authorise, by implementing acts, an exemption for up to 4 years where alternatives are not available or cannot be used for technical or safety reasons, or where technically feasible and safe alternatives would entail disproportionate costs.

Point 8: self-contained, monobloc and plug-in equipment

Point 8 of Annex IV covers self-contained air-conditioning equipment and heat pumps, except chillers. Article 3, point (38) defines the term: a complete factory-made system in a suitable frame or casing, fabricated and transported complete or in two or more sections, which can contain isolation valves and in which no gas-containing parts are connected on site. If a technician makes the refrigerant connection on site, you are not in point 8.

Annex IV pointEquipmentGWP limitDate of prohibition
8(a)Plug-in room air-conditioning equipment which is moveable between rooms by the end userHFCs with a GWP of 150 or more1 January 2020
8(b)Plug-in room, monobloc, other self-contained air-conditioning equipment and self-contained heat pumps, maximum rated capacity up to and including 12 kWA GWP of 150 or more; where safety requirements at the site of operation would not allow less than 150, the limit is 7501 January 2027
8(c)The same categories, up to and including 12 kWAny fluorinated greenhouse gas; where safety requirements would not allow alternatives, the limit is 7501 January 2032
8(d)Monobloc and other self-contained air-conditioning equipment and heat pumps, more than 12 kW but not exceeding 50 kWA GWP of 150 or more; fallback limit 750 on safety requirements1 January 2027
8(e)Other self-contained air-conditioning equipment and heat pumpsA GWP of 150 or more; fallback limit 750 on safety requirements1 January 2030

Notice the ordering: point (d), the 12 to 50 kW band, falls on the same date as point (b), while point (e), which catches everything else, only arrives in 2030. The capacity band matters more than intuition suggests.

Point 9: split air conditioning and split heat pumps

Article 3, point (39) defines a split system as a system consisting of a number of refrigerant piped units that form a separate but interconnected unit, requiring the installation and connection of refrigerant circuit components at the point of use. The footnote to point 9 adds a line many people miss: for the purposes of the Regulation, fixed double duct heat pump and air-conditioning equipment shall be considered split (category number 9) and be subject to the same requirements.

Annex IV pointEquipmentGWP limitDate of prohibition
9(a)Single split systems containing less than 3 kg of Annex I gasesAnnex I gases with a GWP of 750 or more — no safety exception1 January 2025
9(b)Split air-to-water systems, rated capacity up to and including 12 kWA GWP of 150 or more1 January 2027
9(c)Split air-to-air systems, rated capacity up to and including 12 kWA GWP of 150 or more1 January 2029
9(d)Split systems, rated capacity up to and including 12 kWAny fluorinated greenhouse gas1 January 2035
9(e)Split systems, rated capacity of more than 12 kWA GWP of 750 or more1 January 2029
9(f)Split systems, rated capacity of more than 12 kWA GWP of 150 or more1 January 2033

Points (b) to (f) all carry the same closing formula: except if required to meet safety requirements at the site of operation. Point (a) does not. For single splits below 3 kg the 750 line of 1 January 2025 is hard, and it is precisely the line that took R-410A (GWP 2 088 under the Annex VI method) out of that segment and left R-32 (GWP 675, the binding Annex I value).

The status of the two gases is set out on the R-410A and R-32 pages, and the safety consequences of moving to A2L in refrigerant safety classes A1, A2L and A3.

The safety exception: what it is and what it is not

The Annex IV wording is "except if required to meet safety requirements at the site of operation". The term is defined in Article 3, point (42): requirements on the safety of using fluorinated greenhouse gases and natural refrigerants, or products and equipment containing or relying on them, prohibiting the use of certain fluorinated greenhouse gases or their alternatives, including when contained in a product or in equipment at a specific place of intended utilisation due to site and application specificities, set out in Union or national law, or in a non-legally binding act containing technical documentation or standards that have to be applied to ensure safety at the specific location, provided they are in accordance with the relevant law.

Three practical consequences follow.

It is not a preference. There must be a legal requirement or an applicable standard that actually prohibits the alternative at that site. An A2L refrigerant being awkward to install is not a safety requirement.

In point 8 it does not hand you a blank cheque. Points (b) to (e) say it expressly: if safety requirements at the site of operation would not allow fluorinated greenhouse gases with a GWP of less than 150, the GWP limit is 750. The exception moves the threshold, it does not remove it. In point 9(b) to (f) the text stops at the general formula, with no written fallback limit.

It has to be labelled and documented. Article 12(15) requires that in the cases referred to in points 2(b), 4, 5(c), 7(b), (c) and (d), 8(b) to (e), 9(b) to (f), 11(c), 16, 17(a), (b) and (c), and 19(a) and (b) of Annex IV, the product or equipment be labelled with an indication that it shall be used only where required by the safety requirements or national safety standards, and that those requirements or standards be specified on the label.

Article 13(19) closes the loop at commissioning: for equipment listed in points 2(b), 4, 5(c), 7(b), (c) and (d), 8(b) to (e), 9(b) to (f), 11(c), 17(c) and 19(b) of Annex IV, putting into operation after the respective prohibition date is prohibited unless the operator can provide evidence either that the relevant safety requirements at the particular location do not permit the installation of equipment using gases below the GWP value specified, or that the equipment was placed on the market before the relevant prohibition date. Article 13(20) requires the documentation to be kept for at least 5 years and made available on request.

Checklist before you quote

  • Decide whether the equipment is self-contained or splitArticle 3, point (38) for self-contained, point (39) for split; fixed double duct falls under point 9 by the footnote.
  • Read the rated capacity, not the catalogue cooling outputThe Annex IV bands are up to and including 12 kW, more than 12 kW, and at point 8(d) more than 12 kW but not exceeding 50 kW.
  • For single splits, check the charge against 3 kgPoint 9(a) applies to single split systems containing less than 3 kg of Annex I gases.
  • Compare the GWP with the limit in the correct row750 at points 9(a) and 9(e), 150 at points 9(b), (c) and (f), any fluorinated greenhouse gas at point 9(d).
  • Do not assume the safety exceptionPoint 9(a) has none; at point 8(b) to (e) the exception lowers the threshold to 750, it does not remove it.
  • Check whether the label needs the safety statementArticle 12(15) lists the points concerned and requires the requirement or standard to be specified on the label.
  • For older stock, prepare the evidenceArticle 11(1), fifth subparagraph: one year after the date, resale requires evidence of lawful placing on the market before that date.
  • Confirm that installation goes to a certified undertakingArticle 11(7) for charged non-hermetically sealed equipment, with the seller records in Article 7(4).
  • Check the servicing side as wellArticle 13(4) for air conditioning and heat pumps from 1 January 2026, with the reclaimed or recycled window until 1 January 2032.

Frequently asked questions

Can I install in 2027 a split unit bought in 2024?

Article 11 prohibits placing on the market, not installation. If the equipment was lawfully placed on the market before the Annex IV date, that article does not stop the installation. Watch Article 13(19) though: for the equipment listed there, including points 9(b) to (f), putting into operation after the prohibition date requires evidence that the equipment was placed on the market before that date, and the documentation is kept for at least 5 years under paragraph 20.

Is a double duct unit monobloc or split?

The footnote to point 9 of Annex IV is explicit: for the purposes of the Regulation, fixed double duct heat pump and air-conditioning equipment shall be considered split, category number 9, and be subject to the same requirements. It does not sit in point 8, even though physically it is one box.

Why did R-32 replace R-410A in single splits?

Because of Annex IV, point 9(a): from 1 January 2025, single split systems containing less than 3 kg of Annex I gases may no longer be placed on the market if they use Annex I gases with a GWP of 750 or more. R-410A has a GWP of 2 088 under the Annex VI method and crosses the line. R-32 has 675, the binding Annex I value, and stays below. The detailed comparison is in R-32 or R-410A.

Does a safety requirement let me use any gas?

No. At points 8(b) to (e) the text says plainly that if safety requirements at the site of operation would not allow fluorinated greenhouse gases with a GWP of less than 150, the GWP limit is 750. The exception lowers the threshold to 750; it does not cancel it. Article 3, point (42) also requires the prohibition of the alternative to come from Union or national law or from a standard that has to be applied at that location, not from an installation preference.

Can I still sell my stock after the ban date?

Equipment lawfully placed on the market before the date may be supplied onwards. However, under Article 11(1), fifth subparagraph, one year following the individual Annex IV date the subsequent supply or making available to another person in the Union is allowed only if evidence is provided that the equipment was lawfully placed on the market before that date. Build that file now, not at the inspection.

Does the prohibition apply to spare parts too?

Article 11(1), first subparagraph covers products and equipment "including parts thereof". The second subparagraph then derogates for parts required for repair and servicing of existing equipment listed in Annex IV, on three cumulative conditions: the repair must not increase the capacity, must not increase the amount of gas, and must not change the type of gas to one with a higher GWP.
