Qualifications required to work on equipment containing F gas

Qualifications and certificates you must have to work on systems that contain a fluorinated greenhouse gas (F gas).

You must be qualified to work on systems and equipment containing fluorinated greenhouse gases (F gas) that the EU regulates.

You need different qualifications for:

  • stationary refrigeration and air conditioning (SRAC systems), including heat pump systems
  • stationary fire protection systems
  • mobile air conditioning systems
  • electrical switchgear
  • solvent recovery

You must be qualified as an individual (have a personal qualification certificate) even if you work for someone else.

If you’re a business that works on third party systems or equipment, your engineers must have personal qualifications. You must also have a company F gas certificate.

If you’re a sole trader, you must have a personal qualification and a company F gas certificate.

Check if you’re qualified

You’re qualified to work on systems that contain F gas if you have:

  • an in-date certificate issued by an accredited organisation
  • an equivalent qualification that another EU member state recognises

If you qualified under 2006 F gas rules, you can work if your certificate is in date. You’ll need to requalify when your certificate expires.

You can use certificates from organisations that no longer run F gas courses if they are in date. You’ll need to requalify when your certificate expires.

If you carry out work without an in-date certificate, you could be subject to enforcement action.

Stationary refrigeration and air conditioning (SRAC) systems, including heat pump systems

To work on these systems you must be qualified if you want to:

  • install new systems
  • service and maintain them
  • check leaks
  • recover refrigerant gases
  • decommission and dispose of old systems

Since 1 July 2017, you also need a qualification to work on refrigeration systems in:

  • trucks that weigh more than 3.5 tonnes
  • trailers made to be towed by trucks or tractors

Choose your SRAC qualification

There are 4 categories for qualifications. You need a:

  • category 1 certificate - to carry out all activities
  • category 2 certificate - to install, maintain, service and recover refrigerant from systems containing less than 5 tonnes of CO2 equivalent (CO2e)
  • category 3 certificate - to recover refrigerant from systems that contain less than 3 kg of F gas
  • category 4 certificate - to check equipment for leaks if you don’t break into the refrigeration circuit

You must have one of these qualifications, or a relevant qualification from one of these accredited organisations:

Stationary fire protection systems

You must have one of these qualifications to work on a fire protection system that contains F gas of 5 tonnes or more CO2 equivalent (CO2e):

  • a Fire Industry Association (FIA) F gas certificate for individuals
  • an equivalent qualification that another EU member state recognises

Mobile air conditioning systems

You must be qualified to recover refrigerant from mobile air conditioning systems in:

  • goods vehicles weighing less than 3,500kg
  • passenger vehicles with 8 seats or fewer

You must have one of these qualifications, or a relevant qualification from one of these accredited organisations:

Electrical switchgear

You must be qualified to carry out work on electrical switchgear that contains sulfur hexafluoride (SF6). This includes:

  • installing new systems
  • carrying out maintenance
  • recovering SF6
  • decommissioning and disposing of old systems

You must have one of these qualifications, or a relevant qualification from one of these accredited organisations:

You can recover SF6 for up to a year before you qualify if you:

  • work under the supervision of a qualified person
  • are on a listed course, an internal training course at a utility company, or an equivalent course in another EU country

Solvent recovery

You must have one of these qualifications to recover solvents from equipment:

You can recover solvents for up to a year before you qualify if you:

  • work under the supervision of a qualified person
  • are on the Fraser Technology training course or an equivalent course in another EU country
