What Businesses Need to Know About New UK F-Gas Changes

All businesses across the UK that rely on air conditioning, refrigeration, or heat pump systems need to be preparing for significant regulatory changes.

The UK government has proposed major changes to F-Gas regulations that would accelerate the phase-down of hydrofluorocarbons (HFCs), the refrigerants that are commonly used in cooling systems.

These changes are part of the UK's broader strategy to reduce greenhouse gas emissions and move towards net-zero. For any businesses that use commercial air conditioning or refrigeration equipment, understanding the upcoming changes is essential for long-term compliance and planning.

In this blog, we will explain what the proposed F-Gas changes mean and how your business can prepare.

What are F-Gas Regulations

F-Gas regulations control the use of fluorinated greenhouse gases, which include hydrofluorocarbons (HFCs). These gases are widely used as refrigerants in air conditioning.

While effective for cooling, HFCs have a very high global warming potential, often hundreds or even thousands of times greater than carbon dioxide. Because of this environmental impact, the government are looking to reduce their use through phased regulatory limits.

UK's Proposed HFC Phase-Down

In November 2025, the UK government launched a consultation proposing a much faster phase-down of HFC refrigerants used in cooling and heating systems. Under the proposed reforms, the UK could achieve a 98.6% reduction in HFCs by 2048, with new quota reductions starting in 2027. The interim targets for 2030-2050 would further reduce supply each year.

These proposals go significantly further than the current target of a 79% reduction by 2030, meaning the availability of traditional refrigerants will likely fall more quickly than previously expected.

Why These Changes Matter for Air Conditioning and Refrigeration

The phase-down primarily affects industries that rely on refrigerants, including commercial air conditioning, refrigeration in retail and hospitality, industrial cooling, and heat pump technology.

Because the regulations limit how much HFC can be placed on the UK market each year, the result is typically reduced supply and rising costs for older refrigerants.

For businesses running systems that rely on higher-GWP refrigerants such as R410A, long-term servicing and maintenance may become more expensive as availability tightens.

What This Means for UK Businesses

For organisations operating air conditioning or refrigeration equipment, the upcoming F-Gas changes could affect several areas.

Higher Refrigerant Costs

As HFC quotes are reduced, supply becomes more limited. Historically, this has led to a significant increase.

Long-Term Compliance Planning

Businesses need to ensure that their systems remain compliant with evolving regulations, including requirements for certified engineers, leak testing, and proper refrigerant handling.

Pressure to Upgrade Older Systems

Older systems using higher-GWP refrigerants may become less economical to maintain over time, encouraging businesses to consider upgrading to newer technology.

How Your Business Can Prepare

Although the most significant reductions will begin around 2027, businesses should start planning early.

Here is how you can prepare:

• Review your existing equipment, understanding which refrigerants your current system uses and see if it is still compliant.

  
  

• Start planning for long-term upgrades if your equipment relies on high-GWP refrigerants. Developing a replacement strategy now can help avoid future costs that will end up costing you thousands.

  
  

• Ensure F-Gas compliance with regular servicing by one of our certified engineers, which will help ensure your systems remain compliant and operate efficiently.

  
  

• Improve system efficiency by keeping it well-maintained, which will help reduce refrigerant loss, energy consumption and operating costs.

We can Help You Prepare

The UK's proposed F-Gas reforms represent one of the most significant shifts the refrigeration and air conditioning sector has seen in decades. With a potential 98.6% reduction in HFCs by 2048, the industry is moving steadily toward lower-impact refrigerants and more energy-efficient systems.

For any business, the message is simple: plan ahead! You need to understand how these changes will affect your systems now can help you avoid massive unexpected costs and ensure long-term compliance.
