Understanding EU F-Gas Regulation 2024/573: What You Need to Know

What Is the F-Gas Regulation?

The EU F-Gas Regulation 2024/573 is the cornerstone piece of legislation governing the use of fluorinated greenhouse gases across Europe. This new regulation has formally repealed and replaced the previous EU F-Gas Regulation 517/2014 to introduce stricter controls and a more aggressive phase-down of HFCs.

It is crucial to note the distinction between the EU and the UK post-Brexit. While the EU operates under the new Regulation 2024/573, Great Britain continues to operate under the UK Retained F-Gas Law (which largely mirrors the framework of the original 517/2014 regulation, though it is subject to its own updates). Understanding both frameworks is essential for passing the F-Gas certification exam and is a legal requirement for anyone handling fluorinated refrigerants professionally.

The overarching goal remains to drastically cut F-gas emissions through a combination of phase-down quotas, equipment bans, leak prevention obligations, and certification requirements.

The HFC Phase-Down Schedule

The centrepiece of Regulation 2024/573 (and UK Retained F-Gas Law) is the HFC phase-down, which progressively reduces the total quantity of hydrofluorocarbons (HFCs) that can be placed on the market. The phase-down is measured in CO2 equivalent tonnes, not in absolute weight, meaning that high-GWP refrigerants are penalised more heavily.

The aggressive reduction means that high-GWP refrigerants like R-404A (GWP 3922) and R-507A (GWP 3985) are facing a rapid phase-down. The industry is experiencing a massive shift away from these gases towards lower-GWP alternatives, particularly mildly flammable A2L refrigerants such as R-32 (GWP 675) and R-454B. Other alternatives include R-290 propane (GWP 3), R-744 CO2 (GWP 1), and various HFO blends.

Global Warming Potential (GWP) Limits and Bans

The regulations introduce specific GWP limits that prohibit the use of high-GWP F-gases in certain types of new equipment:

• Domestic refrigerators and freezers: F-gases with GWP of 150 or more banned from January 2015
• Commercial hermetically sealed refrigeration: GWP of 2500 or more banned from January 2020; GWP of 150 or more banned from January 2022
• Centralized commercial refrigeration (multipack systems): GWP of 150 or more banned from January 2022 (with exceptions for the primary circuit of cascade systems, where GWP up to 1500 is permitted)
• Single split air conditioning with charge below 3 kg: GWP of 750 or more banned from January 2025
• Movable room air conditioning: GWP of 150 or more banned from January 2020

These bans do not apply to equipment designed to cool products below -50°C, or to equipment designed for applications intended to cool to temperatures below -50°C.

Leak Checking Obligations

The regulation imposes mandatory leak checking for equipment containing F-gases. The frequency of checks depends on the CO2 equivalent charge of the system:

• 5 tonnes CO2 equivalent or more: Leak checks at least every 12 months
• 50 tonnes CO2 equivalent or more: Leak checks at least every 6 months
• 500 tonnes CO2 equivalent or more: Leak checks at least every 3 months (and a permanent leak detection system must be installed)

If a leak detection system is installed, the interval between periodic checks is doubled. Operators must ensure that any detected leaks are repaired without undue delay, and a follow-up check must be carried out within one month of the repair to verify it has been effective.

Record-Keeping Requirements

Operators of equipment containing F-gases in quantities of 5 tonnes CO2 equivalent or more must maintain records for each piece of equipment. These records must include:

• The quantity and type of F-gas contained in the equipment
• The quantity of F-gas added during installation, maintenance, or servicing
• The quantity of F-gas recovered during servicing, maintenance, or final disposal
• The identity of the company or technician who carried out the work
• The dates and results of all leak checks
• Relevant information identifying the equipment

These records must be kept for at least five years and made available to the relevant competent authority upon request.

Certification Requirements

The regulation requires that any person or company carrying out installation, servicing, maintenance, repair, or decommissioning of equipment containing F-gases must hold the appropriate certification. In the UK, this means holding a valid City & Guilds 2079 certificate (or equivalent recognised qualification) at the appropriate category level.

Companies must also hold a company certificate issued by a certification body, confirming that they employ sufficient certified personnel and have the necessary tools and procedures in place.

Recovery Obligations

F-gases must be recovered by appropriately certified personnel before the final disposal of equipment and, where necessary, during servicing and maintenance. Recovered F-gases must be recycled, reclaimed, or destroyed. It is illegal to deliberately vent F-gases into the atmosphere.

What This Means for Technicians

For working HVAC and refrigeration technicians, the practical implications of Regulation 2024/573 (and UK Retained F-Gas Law) are significant:

1. You must be certified to legally handle F-gases — no exceptions
2. You must keep detailed records of all refrigerant handling activities
3. You must follow leak checking schedules based on system charge size
4. You should be familiar with lower-GWP alternatives, as the industry transitions away from traditional high-GWP HFCs like R-404A towards A2L options
5. You must recover refrigerant before decommissioning any equipment
6. You face penalties for non-compliance, including fines and loss of certification

Understanding these regulations is not just exam knowledge — it is the foundation of responsible, legal, and environmentally conscious practice in the refrigeration and air conditioning industry.
