Before you book
Anyone who installs or services air conditioning must hold an F-gas certificate. We show what we could confirm, and nothing more.
F-gas verifiedWe found the company's F-gas certificate on a public register and the details match. Still ask to see it.
F-gas claimedThe installer says it holds a certificate, but we could not match it on a register. Ask for the certificate number and check it yourself.
F-gas not foundWe found no certificate on the registers and no claim on its site. This is not the same as not certified, because some firms opt out of public registers. Do not let work start until you have seen a certificate.
What to check
1
It is a legal requirement for installing and servicing air conditioning. The badge on each profile shows what we could and could not confirm.
2
Unit size, pipe run, electrics and where the outdoor unit goes all change the price. Two quotes show you the spread.
3
Some brands extend their warranty only when an approved installer fits the unit. Profiles show what each installer states.
