F-Gas Compliance Guide for UK Air Conditioning Installers

The Fluorinated Greenhouse Gases (F-Gas) Regulations govern the use, containment and recovery of fluorinated greenhouse gases in the United Kingdom. They apply to any business or individual that installs, services, maintains or decommissions stationary refrigeration, air conditioning and heat pump equipment containing HFC refrigerants such as R410A, R32 and R407C. Compliance is not optional, it is a legal obligation enforced by the Environment Agency and equivalent regulators across the UK.

What Records Must Be Kept?

For every fixed air conditioning system you install or service that contains F-Gas refrigerant above 5 tonnes of CO2 equivalent (tCO2e), you are required to maintain specific records. These include the installation record (documenting who carried out the installation, the equipment installed, the refrigerant type and quantity), the refrigerant charge record (showing the factory charge, any additional refrigerant added on site, and the total system charge), and a commissioning certificate confirming the system has been commissioned in accordance with the manufacturer's instructions. These records must be retained for at least five years and made available to regulators on request.

Leak Checking and CO2 Equivalent Thresholds

The frequency of mandatory leak checks depends on the system's total CO2 equivalent charge, calculated by multiplying the refrigerant charge (in kg) by the refrigerant's Global Warming Potential (GWP). Systems containing between 5 and 50 tCO2e require a leak check every 12 months (or every 24 months if fitted with a fixed leak detection system). Systems between 50 and 500 tCO2e require checks every 6 months (or 12 months with leak detection). Systems above 500 tCO2e require checks every 3 months (or 6 months with leak detection). Understanding these thresholds is essential, failing to carry out leak checks on time is one of the most common causes of non-compliance.

Penalties for Non-Compliance

Non-compliance with the F-Gas Regulations can result in significant consequences. Regulators have the power to issue improvement notices, monetary penalties, and in serious cases, prosecution. Beyond the legal risks, failing to maintain proper documentation can damage your reputation with customers, invalidate equipment warranties, and create problems during property transactions or insurance claims. Many installers underestimate how much administrative work is involved in producing compliant documentation for every job, which is exactly the problem AirCon Docs was created to solve.
