The Fluorinated Greenhouse Gases Regulations 2015 are in place across England, Wales and Scotland to help the UK and EU to phase out the use of hydrofluorocarbons (HFC).
As of January 2020 HFCs with a global warming potential greater than 2,500 will be banned and will effect equipment such as ice cream freezers, bottle coolers, stand-alone retail displays, blast chillers, and commercial freezers that contain between 2kg and 10kg of refrigerant.
To support the ban, UK bodies, including the environmental agency, have issued guidance on what actions businesses must take to be compliant with the new legislative requirements, including calculating the CO₂ equivalent quantity of F-gas and adopting alternative measures like switching to low global warming refrigerants. The guidance also provides information on help with the cost of replacing the refrigerant system through the Enhanced Capital Allowance Scheme.
