All sub-contractors working in the refrigeration and air conditioning sector or involved in any part of the installation, servicing, maintenance, repair or decommissioning of any stationary refrigeration, air conditioning, or heat pump system must be registered with REFCOM (or equivalent EU company registration certifying body). They must be registered as a company as well as holding their individual F-Gas qualification such as City & Guilds 2079, BESA FGas, CITB J11, or LCL FGas.

There is confusion about certification types with people commonly referring to “having their F-Gas” whilst referring to either their personal qualifications or their company registration certificate depending on the context of the conversation.

For clarity, every person (natural person) working in the sector must hold a personal F-Gas qualification and every business entity (legal person), whether working as a sole trader or a limited company, must hold a company registration certificate (REFCOM) for any work involved with any part of an installation, repairs, servicing, maintenance, or decommissioning.
