Uses of F gas (HFCs) exempt from the phase down

Uses of hydrofluorocarbons (HFCs) - the most common type of F gas - that are not included in the phase down and do not count towards your quota.

The UK is phasing down HFCs, including mixtures, by 79% by 2030 from the average use between 2009 to 2012.

HFCs are exempt from the phase down and don’t count towards your quota if you import or produce them directly for use:

  • as feedstocks (HFCs used in chemical processes to produce other substances, rather than placed directly in equipment)
  • in military equipment
  • in metered dose inhalers for medicines (for example asthma inhalers)
  • to etch semiconductor material (for example, plasma etching)
  • to clean chemicals vapour deposition chambers in semiconductor manufacturing

You must store HFCs in a container labelled for these uses.

HFCs are also exempt from the phase down if you:

  • import HFCs to destroy them
  • export HFCs from the UK in bulk

Selling to a third party

These exemptions do not apply if you sell to a third party, even if the HFCs end up being used for an exempt activity.
