We hope the following information regarding fluorinated greenhouse gases, or F Gases as they have become known, will help you to understand the latest legislation and how it will affect your company.  However if you are in doubt about anything please do not hesitate to call us and we will be happy to offer advice.

The F Gas Regulations use a size threshold.  In the 2006 Regulation, the thresholds were based on the quantity of F gas, measured in terms of the mass of fluid (in kilograms).  For example, mandatory leak tests were required on all refrigeration and air conditioning containing more than 3kg of HFC refrigerant.  The same kilogram threshold applied to all refrigerant types.  Under the 2014 Regulation the thresholds have been changed to CO2 equivalent (CO2e).  This change creates a lower kg threshold for F gases with a high GWP (Global Warming Potential) and will encourage organisations to select equipment that use F gases with the lowest practical GWP.

The principal objective is to contain, prevent and thereby reduce emissions of F gases to minimise the global warming impact of these gases.


The key obligations are summarised as follows:

Leakage Inspections

The mandatory leak test of all systems with a threshold of 5 tonnes CO2e or more.

The system must be checked for leakage within one month after a leak has been repaired to ensure the repair has been effective.

Maintenance of Records

Records must be maintained of leak tests, F gases added or removed during installation and service for each piece of equipment and kept for 5 years.


F gases must be recovered for recycling, reclamation or destruction.  Venting of refrigerant to atmosphere is prohibited.

Training & Certification

All engineers carrying out work on refrigeration systems must be qualified to City & Guilds or CITB level of competence in refrigerant handling and hold the relevant certification. (As do all Universal Refrigeration engineers).


Equipment containing F gases must be labelled, clearly showing quantity and type of F gas installed.  From 1 January 2017 new equipment must also show the CO2 equivalent.

The above obligations are to be met by the operators of the equipment (usually the owners) and refrigeration contractors.

If you are an existing Universal Refrigeration customer with a maintenance contract we will ensure that we fully comply with F gas Regulations.
