Interested in learning more about F-Gases? Read on!

Hydrofluorocarbons (HFCs and HCFCs) are a type of Fluorinated gases (F-gas) which feature in many air conditioning, refrigeration and heat-pump systems. If released into the atmosphere, they can have a harmful global warming effect.

The Department for Environment Food & Rural Affairs (DEFRA) is consistently reviewing the use of F-gas to combat climate change. As a result businesses are legally obliged to keep their air conditioning system regularly maintained and tested for F-gas leaks.

F-gas certification and compliancy is enforced by the Environmental Agency and local authorities. Businesses unable to provide the necessary records to prove their compliancy with F-gas regulations will receive a penalty notice and further fines if not addressed.

F-gas rules and regulations apply to all sizes and types of businesses operating an air conditioning, refrigeration system with the CO2 equivalent charge weight of 5 tonnes and above. The frequency of F-gas testing is required as follows:


Tonnes CO2 Equivalent Charge Weight

FGas inspections

5-50 tonnes

At least every 12 months

50-500 tonnes

At least every 6 months


At least every 3 months


A leak detection system must be installed on equipment containing the F-gas equivalent to more than 500 tonnes of CO2. If a leak is detected, the system alerts the operator and the service company responsible for your equipment. The leak detection system must be checked once a year to ensure it is working correctly and to comply with F-gas regulations.
