F gas: guidance for users, producers and traders

Fluorinated greenhouse gas (F gas) requirements, including the phasing out of HFCs and product bans, and what you'll have to do if there's no Brexit deal.

Guidance on regulation of the use of fluorinated greenhouse gases (F gases) like hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

This affects anyone who:

  • manufactures, uses or services equipment that contains F gases, like refrigeration and air conditioning systems, solvents or aerosols
  • produces or wholesales F gas
  • imports or exports F gas, or equipment containing F gas, to or from the EU


If you have any questions about this guidance contact the Environment Agency:

Brexit guidance for F gas users, producers and traders

'Operators' (users) of equipment containing F gas

Read guidance in this section if you operate equipment that contains F gas.

You’re the operator of equipment if you’re in charge of its day to day running, including as a service company. You don’t have to own equipment to be the operator.

Operators of equipment containing HCFCs

Read guidance in this section if you operate equipment that contains hydrochlorofluorocarbons (HCFCs).

HCFCs are banned in the EU, but refrigeration or air conditioning equipment may contain HCFCs if it was either:

  • manufactured in the EU before 2001
  • imported from outside the EU

Service companies and installers

This section is for companies that install or service equipment that contains F gas.

If you’re in charge of the day to day operation of equipment containing F gas, you also need to read the guides in the section for operators.

HFC phase down

The EU is phasing down the use of hydrofluorocarbons (HFCs) from 2015. Find out how the phase down will work, and how to get a quota to produce or import HFCs.

Equipment manufacturers and importers

Find out what records you’ll need to keep and how to label equipment if you manufacture products containing F gas in the EU, or import them to the EU.

Also find out about EU bans on products containing F gas.

Semiconductor manufacturers and magnesium smelters

Requirements if you use SF6 in magnesium smelting, or any F gas to manufacture semiconductors.

Businesses with record keeping requirements

Record keeping requirements if you destroy, export or use the following gases as a feedstock in a chemical process:

Regulated gases and supporting guidance

Find a list of F gases covered by the F gas regulation, and a list of gases that aren’t regulated, but which you’ll have to keep records about.

Also find out how to calculate the carbon dioxide (CO2) equivalent weight of an F gas. Many requirements in the regulation are based on CO2 equivalent weights.
