Bans on F gas in new products and equipment: current and future

Uses of fluorinated gases (F gases) that are banned or will be banned in the future.

You must not place products or equipment containing banned F gases on the market in Great Britain.

If you do, you could receive a civil penalty for breaking the law. For further information, see the Environment Agency enforcement and sanctions policy.

If you see a banned item for sale, report it to f-gassupport@environment-agency.gov.uk.

Refrigerants: F gases banned in new products

F gases which produce trifluoromethane as a by-product

When manufacturing F gases in Great Britain if you produce trifluoromethane as a by-product, you must recover or destroy it. This includes trifluoromethane produced during the manufacturing of feedstocks for F gas production.

When importing F gases into Great Britain if trifluoromethane is a by-product of the F gas manufacturing process, you must:

  • get a declaration from the producer that the trifluoromethane has been recovered or destroyed
  • supply this declaration with your import paperwork

This includes trifluoromethane produced during the manufacturing of feedstocks for F gas production.

Magnesium smelting: banned sulphur hexafluoride

You must not use sulphur hexafluoride for:

  • magnesium die-casting
  • recycling magnesium die-casting alloys

Other uses: F gases banned in new products

You must not use F gases in:

  • tyres
  • windows
  • footwear

Refillable containers

You must sell F gas in refillable containers if it will be used:

  • to service, maintain or fill refrigeration, air-conditioning or heat-pump equipment (RACHP), fire protection systems or switchgear
  • as a solvent

Your containers are only classed as refillable if your customers can return containers to you for refilling. You must take back containers from customers to refill them.

Exemptions from the bans

The bans do not apply to equipment that:

  • produces lower greenhouse gas emissions over its total lifecycle, including energy consumption
  • is more efficient than alternative equipment that does not contain HFCs
  • is used in military hardware, such as tanks and aircraft

The bans still apply to other equipment used by the military, such as refrigeration.

Requesting an exemption

You may request an exemption if:

  • alternatives are not available for a specific product or piece of equipment, or a specific category of product or equipment
  • alternatives would cause disproportionate costs
  • the ban creates technical or safety issues

You can request an exemption by providing evidence and reports that show how your request meets the exemption criteria by emailing fgas@defra.gov.uk.

Exemption requests can only be granted by passing legislation and assessing supporting evidence, which can take at least 12 months to complete. If granted, exemptions last for up to 4 years.

To check how much a gas contributes to global warming, you can calculate the carbon dioxide equivalent quantity of an F gas.
