F-Gas, TM44 & Air Conditioning Compliance
Air conditioning is a regulated trade. Refrigerant work is governed by F-Gas law, and larger systems need periodic TM44 inspections. Here is what you need to know — and how we keep you compliant.
Compliance
UK air conditioning is regulated: refrigerant work must be done by an F-Gas-certified company, and systems of 12kW or more need a TM44 inspection every five years. Tempest is F-Gas / REFCOM registered and offers TM44 inspections and service contracts across Surrey.
F-Gas Certified Installer
By law, any company that installs, services or decommissions air conditioning containing fluorinated refrigerant must hold F-Gas company certification. It is not a nice-to-have or a marketing badge — it is a legal requirement, and using an uncertified installer can leave you exposed. Here is what F-Gas certification means, why it matters, and how to verify it before work begins.

If your business operates an air conditioning system with an effective rated output of 12kW or more, you are legally required to have it inspected at least every five years. This is the TM44 inspection, and failing to hold a valid report can mean a fixed penalty. Here is what the inspection involves, who it applies to, and how to keep your premises compliant.

Air conditioning is a long-term investment, and like any mechanical system it performs best with regular, planned maintenance. A service contract takes the guesswork out of upkeep — scheduled visits, priority response and a clear record of works — protecting both your equipment and your manufacturer warranty. Here is how our planned maintenance works for Surrey homes and businesses.

F-Gas and TM44 are two of the most commonly confused terms in air conditioning compliance — and they are not interchangeable. One governs who is allowed to handle your refrigerant; the other governs whether your system has been independently inspected for efficiency. Understanding the difference helps building owners stay compliant and avoid penalties. Here is a plain-English comparison.
