F Gas Regulations

New F-Gas Regulations came into effect in January 2020, so you should have heard of the basics by now to ensure your refrigeration system isn’t affected. These regulations have banned the use of refrigerants with a Global Warming Potential (GWP) value of over 2,500, for servicing refrigeration systems.

This means that from now on, F Gas legislation states that all existing central and larger condensing units (with more than 10kg of HFC 404A) will need to adhere to the 2020 service ban. They will permitted to continue to operate at the existing level, but you will not be able to top up the system with virgin HFC 404A following any service or repair, which should give you time to make the switch. Owners of equipment affected by the service ban have three options:

  • Replace the plant with new equipment using a refrigerant with a lower GWP
  • Replace the R404A with a lower GWP refrigerant (some components may also need to be changed to facilitate the new gas)
  • Use reclaimed or recycled R404A which is still acceptable until 2030.


Systems with less than 10kg are unaffected by the changes in legislation. But, due to it’s limited availability, the cost of R404A will increase and become a very expensive refrigerant to continue using. After January 1st, 2020, it is still legal to continue to operate systems with R404A, but you will not be able to change any refrigerant using virgin R404A following a service or repair.

If your refrigeration system falls into any of the categories below, and uses hydrofluorocarbons (HFC) refrigerants, then you could be affected by the new F Gas regulations. You should look to review your options immediately, as replacements may not be available and could delay repairs:

  • Small hermetically sealed systems – Examples of these include ice cream freezers, bottle coolers and retail displays.
  • Condensing units –These are larger scale systems used to run commercial display cabinets, blast chillers and freezers. Typically used in small shops, or convenience stores.
  • Central pack systems – These are normally used by supermarkets and larger shops to run large amounts of refrigerated equipment.
