HFCs are the most common type of F gases and are mainly used as refrigerants in air conditioning and other refrigeration systems. F gases can also found in other equipment, such as fire protection systems, high voltage switchgear, and specialised industrial processes as well as solvents and types of aerosols.

Frequency of tasks for refrigeration and air conditioning systems
1. Take steps to prevent F gas leakage and repair detected leakage as soon as possible on all stationary systems.
2. Regularly check for leakage.
- CO₂ equivalent 5 tonnes to 50 tonnes: at least every 12 months
- CO₂ equivalent 50 tonnes to 500 tonnes: at least every 6 months
- CO₂ equivalent more than 500 tonnes: at least every 3 months
Hermetically sealed systems benefit from more lenient sets of requirements for example as regards leak checks, always under the condition that the term “hermetically sealed system” is indicated on the label of the equipment. Since 31st December 2016 equipment that contains less than 3 kg F-gases (less than 6 kg if hermetically sealed) is no longer exempt from leak checks.
3. Fit automatic leak detection system for stationary systems above 500 tonnes of CO₂ equivalent.
4. Keep records about refrigeration plant that uses F gases for stationary systems of 3Kg or more, to include;
- The quantity and type of F gas refrigerant installed in each system
- Any quantities of refrigerant added
- The quantity of refrigerant recovered (during service, maintenance or final disposal)
5. Recover F gases during plant servicing and maintenance, and at end of plant life for all stationary systems.
6. Use appropriately qualified personnel to carry out installation, servicing and maintenance, and leakage checking on all stationary systems. Have company certification if employing personnel to undertake installation, maintenance or servicing of RAC systems. There are further obligations for companies employing these personnel or wishing to take delivery of containers of F gas.
7. Label new equipment adjacent to service point/information & in instruction manuals for all stationary systems.
8. The placing on the market of non-refillable containers used to service equipment was banned from July 2007, except for those shown to be manufactured before that time, this is relevant to all systems.
What does compliance look like?
- An up to date register of all refrigeration and air conditioning systems.
- A record of each system covering, types and quantities of F gas contained and further information on addition or recovery, through to end of life.
- A plan of leakage detection checks including frequency of checks.
- The names of the companies undertaking any installation, servicing, and maintenance or leak detection work.
- Relevant competency details and qualifications for all personnel installing, servicing, maintaining refrigeration or air conditioning systems or wishing to take delivery of containers of F gas.
- The results of all inspection, leak test, servicing etc. for each system.
- Copies of all relevant certificates, service reports etc. relevant to each system. The up to date labelling of any new systems installed stating type and quantity of HFC refrigerant used.
