Refrigerant phase-down developments in the UK

F Gas Regulations: Refrigerant Phase-Down Timeline for UK Air Conditioning 

The UK's commitment to reducing greenhouse gas emissions and combating climate change is driving significant changes in the air conditioning industry. The F Gas Regulations, implemented in 2007, aim to minimise the environmental impact of fluorinated greenhouse gases (F-gases). This article outlines the key dates and implications of refrigerant phase-downs for UK businesses and homeowners. 

F-gases are commonly used as refrigerants in air conditioning systems and contribute substantially to global warming. The F Gas Regulations introduced a phase-down schedule to reduce F-gas emissions by 79% by 2030.  This phased approach enables the industry to transition to more environmentally friendly alternatives. 

Key Phase-Down Dates 

1. 2015: The first major milestone saw a 7% reduction in F-gas emissions. This marked the beginning of the phase-down process. 

2. 2016: The European Union introduced a quota system, limiting the placement of new HFCs (hydrofluorocarbons) on the market. 

3. 2018: A 37% reduction in F-gas emissions was enforced, significantly impacting the availability of high-GWP (global warming potential) refrigerants. 

4. 2020: The UK's departure from the EU led to the adoption of the UK F Gas Regulations, mirroring EU rules, retaining the ability to amend as necessary in the future as the UK sees fit. 

5. 2023: A 55% reduction in F-gas emissions takes effect, further restricting high-GWP refrigerant use. 

6. 2024: Pre-charged equipment containing high-GWP refrigerants (e.g., R-410A) cannot be placed on the EU/UK market. 

7. 2030: The final phase-down target aims for a 79% reduction in F-gas emissions. 

Refrigerant Implications 

1. R-410A: Commonly used in air conditioning systems, R-410A faces significant restrictions. New a/c systems will require lower-GWP alternatives as R410 split systems have now been banned for sale in the UK

2. R-32: Considered a more environmentally friendly option, R-32 has gained popularity in recent years and is now the mainstay of split systems and multi-split systems throughout the a/c industry 

3. Natural Refrigerants: Hydrocarbons (e.g., R-290), carbon dioxide (R-744), and ammonia (R-717) are increasingly touted as long term replacements for R32 but these are not yet being adopted, certainly large scale, by manufacturers in the industry. 

What This Means for UK Businesses and Homeowners 

1. Replace or Retrofit: Consider upgrading to systems using lower-GWP refrigerants. 

2. Maintenance and Servicing: Ensure regular maintenance to minimise refrigerant leaks. 

3. New Installations: Specify systems with environmentally friendly refrigerants. 

4. Training and Compliance: Stay updated on regulatory requirements and technician training.  

Conclusion 

The F Gas Regulations' phase-down timeline necessitates proactive planning within the UK air conditioning industry. Understanding these changes enables businesses and homeowners to make informed decisions, minimising environmental impact and ensuring compliance.
