The United Kingdom has updated guidance on the ban on placing on the market single-phase split air conditioners containing less than 3 kg of fluorinated greenhouse gases with a global warming potential of 750 and above. From 1 January 2025, such systems using R-407C and R-410A refrigerants may not be placed on the market in the United Kingdom. Regulators clarified that the ban applies to stationary installations intended to treat air in order to maintain specified indoor temperature, humidity, and cleanliness parameters.
What falls under the definition of banned products
The definition of banned products includes split systems that:
- consist of one outdoor and one indoor unit;
- are connected by refrigerant piping;
- require on-site installation.
At the same time, the rule does not affect equipment used exclusively for product cooling, which falls under the category of refrigeration equipment.
Exceptions (as in the European Union approach)
Exceptions are made for:
- air-to-water systems;
- installations fitted on seagoing vessels.
Transitional provisions and HFC reduction targets
Products already placed on the UK market before 1 January 2025 may continue to be sold by retail chains and dealers provided that supporting documentation is available. At the same time, the United Kingdom continues a phased reduction in the volumes of new hydrofluorocarbons entering the market, with the aim of achieving a 79% reduction by 2030.
Liability and enforcement ⚖️
Breaches of the ban are subject to civil penalties of up to £200,000. Enforcement is carried out by:
- the Environment Agency (England);
- the Scottish Environment Protection Agency;
- Natural Resources Wales;
- local authorities.
Companies that are unsure whether the restrictions apply to a specific model are advised to contact the manufacturer or supplier directly to confirm the equipment category and the type of refrigerant used.
