REFCOM
Building services · F-gas company certification scheme
REFCOM operates a company certification scheme for work involving fluorinated refrigerants in specified refrigeration, air conditioning and heat pump equipment. Company certification is different from an individual technician’s qualification.
Checked Official sources below.
What it covers and whether it is required
Company F-gas certification is a legal requirement for the activities covered by the rules. REFCOM is one recognised certification route, not the only body a business may use. Check the exact activity, refrigerant and jurisdiction before assuming certification is or is not required.
Joining requirements and costs
The business must meet the scheme’s requirements for appropriately qualified personnel and the equipment and procedures needed for the work. Use the current company application criteria and ensure the individual technicians hold the appropriate qualifications too.
Check the current fees with REFCOM before applying. Ask whether the quotation includes application, assessment, renewal and any per-job charges. Use published fees or ask for a written quotation.
What it means for homeowners
Check the company certification and the technician’s relevant qualification before refrigerant work. MCS certification for a heat pump and F-gas certification answer different questions. Ask for commissioning, refrigerant and maintenance records appropriate to the installation.
How to check a claim
Official member, card or certificate check: REFCOM.
Match the record to the named person or contracting business. Check the current scope, not just a logo on a van or an old certificate. If the public record does not show the detail you need, ask the body to confirm it before appointing the business.
Where the scheme applies
The UK has separate Great Britain and Northern Ireland F-gas arrangements. GOV.UK‘s company certification guidance explains when additional requirements apply; confirm the current route for the job location.
Common questions
Does MCS certification replace F-gas company certification?
No. They cover different requirements. Where the work falls within F-gas company certification rules, the business needs the relevant certification as well.
How do I check REFCOM status?
Use the official verification service linked in this guide. Match the person or legal business name, current status and relevant work category. For a guarantee, check the document issued for your contract as well.
