The 2025 Guide to Air Conditioning Regulations in the UK: What Homeowners and Businesses Need to Know
Staying Cool and Compliant in 2025
The world of air conditioning is changing — and fast. As the UK pushes toward its net-zero carbon goals, new regulations are being introduced to make air conditioning systems safer, greener, and more energy-efficient.
For homeowners, landlords, and business owners, these updates mean it’s more important than ever to understand your legal responsibilities and ensure your system is compliant.
At JP Air Conditioning, we make this simple. Our fully qualified engineers work with the latest technology and stay up to date with every regulatory change — so you can enjoy reliable comfort without worrying about compliance.
What’s Changing in 2025?
The key focus of the 2025 UK air conditioning regulations is reducing environmental impact, particularly through stricter control of F-Gases (fluorinated greenhouse gases) used in refrigerants. Here’s what’s coming:
1. F-Gas Phase-Down
The UK is continuing to phase down high-GWP (Global Warming Potential) refrigerants. From 2025, systems using certain high-GWP gases will be restricted or banned. Only low-GWP or natural refrigerants will be permitted in new systems, helping to reduce emissions significantly.
2. Accredited Installers Only
Handling, installing, or servicing any system containing F-Gases must be done by a certified engineer. This ensures the gases are managed safely and legally.
JP Air Conditioning’s engineers are F-Gas certified and trained to handle all modern refrigerant types safely.
3. Energy Efficiency Standards
Under Part L of the Building Regulations, energy performance requirements are becoming tighter. Systems installed in 2025 must meet higher efficiency ratings — meaning they use less power and lower carbon emissions.
4. Maintenance and Record-Keeping
Businesses and landlords are now legally obliged to maintain up-to-date records of refrigerant quantities, leak checks, and servicing. Regular inspections are required for systems with more than 5 tonnes of COâ‚‚ equivalent. Failure to maintain proper records or service equipment can lead to fines and invalid insurance policies.
What This Means for Homeowners
If you have an air conditioning system at home — or are thinking about getting one — these updates are good news.
Newer, compliant systems are:
More energy efficient – lowering your running costs.
Quieter and more reliable – using advanced compressor technology.
Better for the environment – with low-impact refrigerants.
However, it’s crucial to ensure your installation is handled by a qualified professional and that older systems are properly maintained. JP Air Conditioning can inspect your existing unit, advise on whether it meets 2025 standards, and recommend an upgrade if needed.
Even small leaks or outdated refrigerants can cause inefficiency, higher bills, and environmental harm — all of which are avoidable with regular servicing.
What This Means for Businesses
Commercial properties — offices, retail units, restaurants, and industrial facilities — are under increased scrutiny in 2025.
If your system uses high-GWP refrigerants or exceeds 5 tonnes COâ‚‚ equivalent, you must:
- Schedule regular leak checks by certified engineers.
- Keep detailed records of maintenance and refrigerant quantities.
- Ensure your system meets energy performance targets.
Non-compliance can lead to fines, legal penalties, and reputational damage. But there’s also a financial incentive: well-maintained systems run up to 20% more efficiently, reducing operational costs year-round. JP Air Conditioning provides tailored maintenance contracts for businesses across Hampshire, Surrey, and the South East — ensuring every client stays compliant, efficient, and comfortable.
