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.

The Smarter Way to Stay Cool (and Save Money) Rising energy costs are a concern for many Hampshire homeowners — especially during warmer months. While air conditioning used to be seen as a luxury, modern, energy-efficient systems are now one of the smartest ways to reduce household energy waste and maintain perfect comfort year-round. Thanks to new smart air conditioning technology, you can now control, monitor, and optimise your cooling from anywhere — saving energy (and money) without sacrificing comfort. At JP Air Conditioning, we specialise in energy-efficient installations across Hampshire, Surrey, and the South East, helping homeowners enjoy cutting-edge comfort that’s both affordable and sustainable. What Makes Air Conditioning “Smart”? Traditional air conditioning units run at fixed speeds and temperatures — often cooling more than necessary. Smart systems, on the other hand, are designed to think for themselves. Here’s what sets them apart: 1. Wi-Fi Control & App Connectivity Smart air conditioners connect to your home Wi-Fi, allowing you to adjust settings from your smartphone. Forgot to turn the system off before leaving home? No problem — switch it off remotely. Want to cool your bedroom before you arrive? Turn it on from your phone. 2. Intelligent Sensors Many smart systems come with motion and temperature sensors that detect when a room is occupied — automatically adjusting cooling to avoid wasted energy. 3. Learning Algorithms Advanced models “learn” your preferences over time, optimising performance to suit your schedule and habits. 4. Integration with Smart Home Devices Smart air conditioners can integrate with Amazon Alexa, Google Home, or Apple HomeKit, giving you voice control and automated routines. The result? A cooling system that keeps you comfortable while running only when needed. How Smart Air Conditioning Cuts Energy Costs Switching to a modern, efficient system can have a major impact on your bills. Here’s how: Energy-Efficient Inverter Technology All new JP Air Conditioning installations feature inverter-driven compressors, which automatically adjust their speed to maintain your chosen temperature. This uses up to 30–40% less energy than older fixed-speed systems. Zoned Cooling Instead of cooling the entire house, smart systems can target specific rooms or “zones.” You only cool the spaces you’re using — ideal for larger homes or open-plan designs. Accurate Climate Control Smart thermostats ensure precise temperature regulation, avoiding overcooling and unnecessary power usage. Performance Monitoring Smart systems report real-time energy consumption data, allowing you to track and reduce usage over time. By combining inverter technology with smart control, many homeowners in Hampshire are cutting their cooling costs by 20–50% compared to older systems. The Environmental Benefits Energy savings aren’t just good for your wallet — they’re also better for the planet. Smart air conditioning systems use eco-friendly refrigerants with low global warming potential (GWP). Lower power consumption reduces your carbon footprint. Regular maintenance ensures long-term efficiency and minimal waste. JP Air Conditioning works exclusively with trusted, energy-efficient brands such as Mitsubishi Electric, Daikin, and Toshiba — all designed to meet 2025 UK energy and F-Gas standards. Why Upgrade Your Existing System If your air conditioner is more than 10 years old, it’s likely costing you more than it should. Older systems: Use outdated refrigerants that are being phased out. Run at fixed speeds, consuming unnecessary energy. Lack remote control and monitoring features. Upgrading to a smart, inverter-driven system can pay for itself in reduced energy bills and maintenance savings — while keeping your home future-ready. JP Air Conditioning can assess your current system, calculate your potential energy savings, and recommend the most efficient solution for your property and budget. Case Example: A Smart Upgrade in Fleet, Hampshire Recently, JP Air Conditioning installed a Daikin split system in a four-bedroom home in Fleet. The homeowners wanted to keep their property cool in summer without driving up costs. By choosing a smart inverter system with app control, they: Reduced their cooling energy usage by 35% in the first month. Could monitor temperatures room-by-room via smartphone. Reported a quieter, more consistent cooling experience. Small changes like this show just how powerful modern air conditioning can be — both for comfort and cost savings. How JP Air Conditioning Helps You Go Smart We make the upgrade process simple: Free Consultation: We assess your property, current system, and usage patterns. Energy-Efficient Recommendations: We only recommend systems that offer maximum comfort with minimal consumption. Professional Installation: Our certified engineers ensure perfect setup and compliance with 2025 regulations. Aftercare & Maintenance: Regular servicing to maintain peak performance and long-term efficiency. With years of experience and a reputation for excellence across Hampshire and Surrey, JP Air Conditioning helps homeowners enjoy smarter comfort — without complexity. Final Thoughts Smart air conditioning isn’t just a modern convenience — it’s an investment in long-term comfort, efficiency, and savings. Whether you’re upgrading an outdated unit or fitting a new system in your Hampshire home, smart technology helps you stay cool for less — while doing your part for the environment. Ready to go smart?

Why Maintenance Matters More Than Ever When your business relies on a comfortable environment — whether it’s an office, retail space, restaurant or warehouse — a well-maintained air conditioning system isn’t optional, it’s essential. Beyond keeping staff and customers comfortable, regular maintenance ensures your system runs efficiently, stays compliant with UK F-Gas regulations, and avoids expensive breakdowns that disrupt productivity. At JP Air Conditioning, we work with businesses across Surrey, Hampshire and the South East to deliver professional, proactive servicing that extends the life of every system and protects your bottom line. The Business Case for Regular Maintenance Keeping up with an annual maintenance schedule can deliver measurable benefits: Lower running costs – Clean filters and tuned components can reduce energy use by up to 30%. Improved reliability – Prevents costly emergency repairs and downtime. Healthier air quality – Reduces dust, allergens and bacteria in the workplace. Compliance confidence – Meets legal obligations under F-Gas and Health & Safety regulations. Longer equipment lifespan – Regular care prevents premature wear and replacements. In short, maintenance pays for itself — and then some. The Ultimate Annual Maintenance Checklist Here’s JP Air Conditioning’s expert guide to what every Surrey business should include in its annual commercial air conditioning service. 1. Visual Inspection & Safety Checks Inspect outdoor and indoor units for damage, corrosion or debris. Verify secure mounts, electrical connections and pipework. Confirm no leaks, unusual noises or vibration. Check all safety switches and emergency shut-offs. 2. Clean or Replace Air Filters Dirty filters restrict airflow and increase energy consumption.

Drainage & Condensate Line Cleaning Clear condensate trays and drains to prevent leaks or mould growth. 7. Airflow & Temperature Testing Measure airflow rates and output temperatures. Ensure balanced air distribution for consistent comfort. 8. Lubrication & Moving Parts Lubricate fan motors and bearings to reduce friction and noise. 9. Performance Efficiency Test Benchmark system efficiency against manufacturer specifications. Identify any performance drift or component wear. 10. Documentation & Compliance Record Log all maintenance activity, refrigerant data and test results. Keep records accessible for future audits or inspections. JP Air Conditioning provides clients with a full maintenance report after every visit — giving you peace of mind and proof of compliance. Understanding Your Legal Obligations Under UK F-Gas regulations, all businesses operating systems containing fluorinated greenhouse gases must: Conduct regular leak checks by a certified engineer. Maintain detailed service and refrigerant logs. Use qualified F-Gas certified technicians for all work. Dispose of refrigerant and components safely. Failure to comply can result in fines and enforcement action. Partnering with JP Air Conditioning ensures your systems remain fully compliant year-round. How Often Should You Service Your System? While an annual service is the minimum recommendation, some environments require more frequent attention: Offices & Retail: every 12 months Restaurants & Kitchens: every 6 months Data Centres: every 3 months (quarterly) Warehouses: every 12 months, with additional seasonal checks JP Air Conditioning tailors every maintenance plan to your site’s size, usage and system type. Signs Your Air Conditioning Needs Attention Even with routine maintenance, keep an eye out for early warning signs: Unusual noises or vibrations Uneven cooling across rooms Rising energy bills Leaks or damp patches near indoor units Musty or unpleasant smells Catching small issues early can prevent bigger problems later — saving both time and money.

Finding the Perfect Cooling Solution Choosing the right air conditioning system for your property can feel overwhelming. With so many options available, it’s easy to get lost between ducted and wall-mounted systems — the two most popular choices for UK homes and businesses alike. At JP Air Conditioning, we help clients across Hampshire, Surrey, and the South East find the perfect balance of comfort, efficiency, and style. This guide breaks down the key differences, benefits, and ideal use cases for each type of system so you can make an informed decision. What Is a Wall-Mounted Air Conditioning System? Wall-mounted air conditioners — often called split systems — are the most common option in UK homes and small offices. They consist of two main components: An indoor unit mounted high on a wall. An outdoor unit that releases heat and houses the compressor. The two are connected by refrigerant piping and electrical wiring. Key Benefits of Wall-Mounted Units Affordable installation: Typically the most cost-effective option for cooling individual rooms. Quick setup: Minimal disruption — most installations are completed within a day. Compact design: Modern units are slim and discreet. Easy maintenance: Filters are easily accessible for cleaning or replacement. Energy efficiency: Inverter technology adjusts performance to reduce energy use. Best For: Homes, apartments, and small offices Single rooms or open-plan areas Retrofit installations where ducting isn’t practical If you’re after simplicity, affordability, and great energy savings, a wall-mounted system is often the perfect choice. What Is a Ducted Air Conditioning System? A ducted system (also known as central air conditioning) distributes cool or warm air through a network of hidden ducts and vents. The indoor unit is usually installed in the loft, ceiling void, or under the floor, with only subtle grilles visible in each room. Key Benefits of Ducted Systems Seamless aesthetics: All components are hidden, leaving only discreet vents. Whole-property comfort: Provides even temperature control across multiple rooms. Quiet operation: Indoor noise is minimal since the main unit is concealed. Integrated climate control: Can combine heating, cooling, and ventilation in one system. Adds property value: Considered a premium feature in modern homes and commercial spaces. Best For: Large homes, offices, and commercial buildings New builds or major refurbishments (where ducts can be easily installed) Clients seeking a luxury or minimalist aesthetic While ducted systems require higher upfront investment and installation time, their performance, comfort, and design integration make them a favourite for premium properties. Ducted vs Wall-Mounted: Key Differences at a Glance Here’s a quick comparison to help you decide which system fits your needs best: Installation: Wall-mounted → faster, simpler, minimal disruption Ducted → requires ceiling or underfloor space for ductwork Cost: Wall-mounted → more affordable upfront Ducted → higher initial cost, but can be more efficient for large spaces Aesthetics: Wall-mounted → visible indoor unit Ducted → hidden system, only vents visible Noise: Wall-mounted → very quiet, but noticeable near the unit Ducted → virtually silent indoors Coverage: Wall-mounted → best for single rooms Ducted → ideal for whole-home or multi-room cooling Maintenance: Wall-mounted → quick and easy access Ducted → requires professional servicing, but less frequent filter cleaning How to Choose the Right System for Your Property When deciding between ducted and wall-mounted air conditioning, consider the following factors: 1. Size and Layout For small homes or single rooms, wall-mounted units are efficient and easy to install. For larger homes or office spaces, a ducted system provides seamless, even cooling. 2. Budget I f you’re seeking value and simplicity, a wall-mounted system is ideal. If you’re planning a long-term investment in your property or commercial space, ducted systems offer greater efficiency and comfort. 3. Aesthetic Preference Do you prefer a clean, minimalist interior? Ducted systems blend perfectly into modern spaces. Wall-mounted units, though visible, now come in sleek, stylish designs that complement most interiors. 4. Future Flexibility If you plan to expand or renovate, a ducted system might be the smarter long-term choice, as it integrates easily with additional zones or smart climate controls.

Understanding Surrey’s Home Cooling Needs Surrey is home to a diverse mix of properties — from modern flats in Guildford to period houses in towns like Farnham and Epsom. The layout, insulation, and age of a property can all affect the type of system that will work best. In newer, well-insulated homes, you may need less cooling power, but you’ll want a system that can also handle the occasional winter chill. Older homes, on the other hand, may require a solution with stronger airflow and humidity control to deal with warm upstairs rooms and stuffy living spaces.
