UK Refrigerant Regulations Explained

Air conditioning refrigerants are fluorinated greenhouse gases, and the UK F-Gas Regulations control how they are used. In practice the rules require three things: that any company handling refrigerant holds F-Gas company certification (and its engineers hold personal qualifications); that systems are leak-checked and maintained to prevent emissions; and that refrigerant is properly recovered and disposed of at end of life rather than vented.

These obligations are enforced by the Environment Agency. They exist because F-gases are potent greenhouse gases, and uncontrolled leaks are both environmentally damaging and a sign of a poorly maintained system.

A central feature of the regulations is the gradual phase-down of refrigerants with a high global warming potential (GWP). Older gases like R410A have a high GWP, so the industry has been moving to lower-impact alternatives such as R32 in newer split systems, which delivers comparable performance with a smaller environmental footprint.

For you as a buyer this matters in two ways: new equipment is increasingly designed around lower-GWP refrigerants, and older systems on legacy gases may become more expensive to maintain over time as those refrigerants are restricted. It is a genuine factor to weigh when deciding between repairing an old unit and replacing it.

The regulations are the reason it is so important to use an F-Gas certified company. A certified installer charges your system correctly, minimises the risk of leaks, keeps the records the rules require, and recovers refrigerant responsibly if a system is ever removed.

Tempest installs and services air conditioning to these standards across Surrey, fitting equipment from Daikin, Mitsubishi Electric, Fujitsu and Samsung that uses current, lower-GWP refrigerants. If you are weighing up a repair versus a replacement on an older system, we can talk you through the refrigerant implications honestly.
