Buying air conditioning can feel confusing at first. There are portable units, wall mounted systems, DIY air conditioning units, easy fit systems, console units, multi split systems, ceiling cassettes, ducted systems and heat pumps. They can all cool a space, but they do not all solve the same problem.
The right air conditioning system depends on where it is going, how often you will use it, whether you need heating as well as cooling, how much installation work is possible, how quiet it needs to be and what level of efficiency you want.
This air conditioning buyer’s guide is designed to help you understand your options before you buy. It explains the main types of air conditioning available in the UK, where each one works best, how to compare running costs, what to consider for different rooms and when professional advice is worth getting.
If you are completely new to air conditioning, you may also find our guide to how air conditioning works useful before comparing systems.
What Is Air Conditioning?
Air conditioning is a way of controlling indoor comfort by removing heat from a room and transferring it elsewhere. In cooling mode, an air conditioner takes warm air from inside the space, removes heat from it and returns cooler air back into the room.
Different systems do this in different ways. A portable air conditioner usually sits inside the room and vents warm air outside through a hose. A split system uses an indoor unit and an outdoor unit connected together. A multi split system uses several indoor units connected to one outdoor unit.
Many modern air conditioning systems can also heat as well as cool. These systems work as air to air heat pumps, moving heat into the room in colder weather and moving heat out of the room in warmer weather.
This is one reason air conditioning is becoming more popular in UK homes. It is no longer just a product for the hottest days of summer. For many rooms, it can provide year round heating and cooling from one system.
Is Air Conditioning Worth It In The UK?
Air conditioning can be worth it in the UK if you regularly struggle with hot, uncomfortable rooms. Many UK homes are not designed for hotter summer weather. Bedrooms, loft rooms, conservatories, garden rooms, flats, home offices and south facing living rooms can all overheat quickly.
Fans can help you feel cooler by moving air around, but they do not actively remove heat from the room. Air conditioning is different because it reduces the room temperature.
Air conditioning can be especially useful if you want to improve:
- Sleep comfort during warm nights
- Temperature control in a home office
- Comfort in a conservatory or garden room
- Cooling in flats or apartments with limited ventilation
- Heating and cooling in one regularly used room
- Customer and staff comfort in a business space
- Cooling for gyms, cafés, restaurants, offices and server rooms
The key is choosing the right type of system. A portable unit may be enough for occasional cooling. A wall mounted split system may be better for regular use. A multi split system may make more sense if you want to cool several rooms. A commercial space may need a more carefully designed system.
Types Of Air Conditioning Systems
Before comparing brands, prices or features, it helps to understand the main system types. Each one has a different purpose.
| System Type | Best For | Installation | Main Benefit |
|---|---|---|---|
| Portable air conditioning | Temporary cooling, renters, occasional use | No permanent installation | Flexible and easy to move |
| Wall mounted split system | Bedrooms, living rooms, offices, garden rooms | Professional installation usually required | Quiet, efficient and permanent |
| DIY or easy fit air conditioning | Confident DIY users, garden rooms, home offices | Designed for simpler installation | Permanent cooling with less installation complexity |
| Multi split air conditioning | Several rooms from one outdoor unit | Professional installation usually required | Independent room control |
| Console air conditioning | Rooms where high wall space is limited | Professional installation usually required | Low wall positioning |
| Ceiling cassette air conditioning | Large rooms, offices, shops, hospitality spaces | Professional installation required | Strong air distribution |
| Ducted air conditioning | Larger homes, commercial spaces, discreet interiors | Professional design and installation required | Hidden system with grilles or vents |
Portable Air Conditioning
Portable air conditioning is often the simplest way to start cooling a room. A portable unit sits inside the space and vents warm air outside through a hose, usually through a window or suitable vent kit.
Portable air conditioners are popular because they do not usually require permanent installation. They can be moved between rooms, stored away when not needed and used as a quick solution during hot weather.
Best For
- Renters
- Temporary cooling
- Bedrooms used occasionally in summer
- Home offices
- Small rooms
- Situations where a fixed system is not possible
Things To Consider
Portable units are flexible, but they are usually louder than split systems because the main components are inside the room. They also need proper venting. If the warm air hose is not fitted correctly, cooling performance will be reduced.
Portable air conditioning is a good choice when flexibility matters more than quiet operation or long term efficiency. If you need regular cooling in the same room, a fixed split system may be a better investment.
For more help, read our portable air conditioning units buyer’s guide, our guide to which portable air conditioner to buy and our advice on how to install and set up a portable air conditioner.
You can also browse our portable cooling systems.
Wall Mounted Split Air Conditioning
Wall mounted split air conditioning is one of the most popular permanent options for UK homes and businesses.
A split system has an indoor unit mounted inside the room and an outdoor unit installed outside the property. The indoor unit provides cooling or heating, while the outdoor unit handles the heat transfer.
Compared with portable air conditioning, a wall mounted split system is usually quieter, more efficient and more comfortable for regular use.
Best For
- Bedrooms
- Living rooms
- Home offices
- Garden rooms
- Conservatories
- Shops and treatment rooms
- Small offices and studios
Things To Consider
A split system needs a suitable indoor position and outdoor unit location. The system should be sized properly for the room and installed by a suitable professional where required.
For regular use, wall mounted air conditioning is often the best long term option. It can provide summer cooling, winter heating, quiet operation and a neat permanent finish.
For more detail, read our split system air conditioning buyer’s guide and our wall mounted air conditioning guide.
You can browse our high wall mounted air conditioning systems.
DIY And Easy Fit Air Conditioning
DIY and easy fit air conditioning systems are designed to make permanent cooling more accessible. They are often chosen by confident DIY users, tradespeople, garden room owners and people who want a more permanent solution without a traditional full installation process.
These systems can be a useful middle ground between portable air conditioning and a professionally installed split system.
Best For
- Garden rooms
- Home offices
- Workshops
- Outbuildings
- Confident DIY users
- Customers wanting a more permanent option
Things To Consider
Always check the installation requirements carefully. Not every product is suitable for every building, and some types of air conditioning work are regulated.
If you are not confident, or if the installation is more complex, professional advice is recommended.
Read our DIY air conditioning buyer’s guide and our guide comparing DIY air conditioning vs professional installation costs.
You can browse our DIY air conditioning systems and easy fit air conditioning systems.
Multi Split Air Conditioning
A multi split air conditioning system connects multiple indoor units to one outdoor unit. This allows several rooms to be cooled or heated from a single external condenser.
Each indoor unit can usually be controlled separately, making multi split air conditioning useful for homes and businesses where different rooms are used at different times.
Best For
- Multiple bedrooms
- Whole home comfort
- Homes where several outdoor units would look untidy
- Offices with multiple rooms
- Guest accommodation
- Clinics, salons and studios
Things To Consider
Multi split systems need proper design. The number of indoor units, total capacity, pipe runs, outdoor unit location and room layout all matter.
If you only want to cool one room, a single split system is usually simpler. If you want to cool several rooms, a multi split system may be the better long term solution.
Read our multi split air conditioning buyer’s guide and our comparison of multi split vs single split air conditioning.
You can browse our multi split air conditioning systems.
Console And Low Wall Air Conditioning
Console air conditioning systems are positioned lower on the wall, often in a similar location to a radiator. They can be useful when a high wall mounted unit is not suitable because of room layout, windows, beams, low ceilings or design preferences.
Best For
- Rooms with limited high wall space
- Older properties
- Conservatories
- Bedrooms
- Living rooms
- Spaces where low level heating feels more natural
Things To Consider
Console systems take up low wall space, so furniture placement needs to be considered. They can be a strong choice where comfort, heating and discreet positioning are important.
For more help choosing between unit styles, read our guide to high wall mounted vs console air conditioning.
You can browse our console and low wall air conditioning systems.
Ceiling Cassette Air Conditioning
Ceiling cassette air conditioning systems are installed into a ceiling and distribute air across the room. They are common in offices, shops, cafés, restaurants and larger open spaces.
Best For
- Offices
- Shops
- Restaurants and cafés
- Large rooms
- Gyms and studios
- Spaces where wall units are not ideal
Things To Consider
Ceiling cassette systems usually need suitable ceiling space and professional installation. They can provide excellent air distribution, but they require more planning than a portable or wall mounted system.
You can browse our ceiling cassette air conditioning systems.
Ducted Air Conditioning
Ducted air conditioning is one of the most discreet options because air is delivered through grilles or vents rather than visible wall mounted indoor units.
It can be a good choice for larger homes, commercial interiors, hotels, offices, retail spaces and projects where appearance is a priority.
Things To Consider
Ducted systems need proper design, suitable ceiling or void space and professional installation. They are rarely the simplest option, but they can provide a very clean finish when planned correctly.
You can browse our ducted air conditioning systems.
Single Split Vs Multi Split Air Conditioning
A single split system connects one indoor unit to one outdoor unit. A multi split system connects multiple indoor units to one outdoor unit.
Choose single split air conditioning if you want to cool or heat one room, such as a bedroom, home office, living room or garden room.
Choose multi split air conditioning if you want to control several rooms from one outdoor unit. This can be neater, especially where you do not want multiple outdoor units around the property.
If you only need one room, single split is usually simpler and more cost effective. If you know you want several rooms, multi split may be the better long term decision.
For a detailed comparison, read our guide to multi split vs single split air conditioning systems.
Portable AC Vs Split System AC
Portable air conditioning and split system air conditioning can both cool a room, but they suit different customers.
Portable AC is usually best when you want flexibility, lower upfront cost and no permanent installation. It is useful for renters, occasional use and rooms where a fixed system is not possible.
Split system AC is usually best when you want quieter operation, better efficiency, a neater finish and regular cooling or heating in the same room.
The simplest way to compare them is this: portable air conditioning is often a short term comfort solution, while split system air conditioning is usually a long term comfort solution.
Read our full comparison of portable AC vs single split AC.
Choosing Air Conditioning By Room
The best air conditioning system often depends on the room. A small bedroom, sunny conservatory, garden office, restaurant and gym all have different requirements.
Best Air Conditioning For Bedrooms
Bedrooms need quiet operation, gentle airflow, reliable cooling and good temperature control overnight. A wall mounted split system is often the best long term option because it is quiet, efficient and discreet.
A portable air conditioner can work for occasional bedroom cooling, but it will usually be louder and will need a window vent.
Read our guide to the best air conditioning for bedrooms.
Best Air Conditioning For Living Rooms
Living rooms are often larger than bedrooms and may have more people, bigger windows and more open space. A wall mounted split system is often a strong choice, while larger open plan spaces may need more capacity or more careful positioning.
Read our guide to the best air conditioning for living rooms.
Best Air Conditioning For Home Offices
Home offices can become uncomfortable because of screens, computers, printers, sunlight and smaller room sizes. The best air conditioning for a home office should be quiet, efficient and easy to control.
A wall mounted split system, easy fit system or suitable portable unit can all work depending on the room.
Read our guide to choosing the best air conditioner for your home office.
Best Air Conditioning For Garden Rooms
Garden rooms are one of the strongest use cases for air conditioning because they can become very hot in summer and cold in winter.
A heating and cooling wall mounted system or easy fit system can help turn a garden room into a usable year round space.
You can browse our garden room air conditioning systems.
Best Air Conditioning For Conservatories
Conservatories are challenging because they often have lots of glass, high solar gain and large temperature swings. A portable unit may help for occasional use, but a correctly sized fixed system is usually better if you want reliable comfort.
You can browse our conservatory cooling systems.
Best Air Conditioning For Kitchens
Kitchens generate extra heat from cooking, appliances and people moving around. A kitchen may need more capacity than a similar sized bedroom or office.
For open plan kitchen dining spaces, think about how air will move across the whole area rather than just the kitchen zone.
Best Air Conditioning For Nurseries And Children’s Rooms
For nurseries and children’s rooms, the priority is steady comfort rather than very cold air. Choose a quiet system, avoid direct airflow onto a cot or bed and aim for gentle temperature control.
Best Air Conditioning For Flats And Apartments
Flats and apartments can be more complicated because outdoor unit placement, leasehold rules, balcony space and building appearance may all matter.
Portable air conditioning is often the easiest option. Water cooled or specialist DIY options may also be worth considering where a standard outdoor condenser is not practical.
You can browse our air conditioning for flats and apartments.
How Much Air Conditioning Do I Need?
Air conditioning size is usually measured in kilowatts. This refers to cooling or heating capacity, not simply electricity use.
The right size depends on room size, ceiling height, insulation, window size, sunlight, number of people, equipment and how the room is used.
As a rough guide, a small bedroom usually needs less capacity than a living room, conservatory, garden room or commercial space. South facing rooms, loft rooms and rooms with large areas of glass often need more careful sizing.
Common mistakes include buying a unit that is too small because it is cheaper, or choosing a system that is too powerful without considering comfort and airflow.
A correctly sized system should cool the space effectively without running flat out all the time. It should also maintain a steady temperature without creating an uncomfortable draught.
If you are unsure, speak to an expert before buying. Correct sizing is one of the most important parts of choosing air conditioning.
How Much Does Air Conditioning Cost?
Air conditioning costs vary depending on the system type, brand, capacity, installation requirements and whether you are cooling one room or several rooms.
Portable air conditioners are usually the lowest cost option because they do not usually need permanent installation.
DIY and easy fit systems usually cost more than portable units, but can offer a more permanent and efficient solution.
Professionally installed split systems usually cost more again because you are paying for equipment, installation, commissioning and compliance.
Multi split, ceiling cassette and ducted systems can cost more because they involve more equipment, more design work and more complex installation.
The most important thing is not to compare price alone. A cheaper portable unit may be perfect for occasional use, but a poor choice for a bedroom used every night. A higher cost split system may feel expensive upfront, but provide better comfort, quieter operation and useful heating for years.
For more detail, read our guide to how much air conditioning costs in the UK, our guide to air conditioning unit prices and our guide to understanding air conditioning installation costs.
Air Conditioning Running Costs
Air conditioning running costs depend on the system, room size, insulation, outside temperature, electricity tariff, temperature setting and how long you use it.
A simple way to understand running cost is to look at the power input of the unit, how long it runs and what you pay per kilowatt hour for electricity.
However, air conditioning systems do not always run at full power continuously. Many modern systems use inverter technology, which adjusts output depending on demand. Once the room reaches the desired temperature, the system can reduce output to maintain comfort more efficiently.
To reduce running costs, choose the right size system, keep filters clean, close windows and doors while cooling, use sensible temperature settings and avoid overcooling the room.
For more detail, read our guide to air conditioning running costs in the UK.
Can Air Conditioning Heat A Room?
Yes, many modern air conditioning systems can heat as well as cool.
These systems work as air to air heat pumps. In cooling mode, they move heat out of the room. In heating mode, they reverse the process and move heat into the room.
This can make air conditioning useful beyond summer. It can provide efficient heating for bedrooms, home offices, garden rooms, living rooms, shops, studios and commercial spaces.
This does not mean air conditioning will replace every heating system in every home. Whole home heating, hot water, insulation and existing heating systems all matter. But for targeted room comfort, heating and cooling air conditioning can be very effective.
Read our guides to whether air conditioning can heat your home, whether air conditioning can heat a room and air conditioning vs heat pumps for UK homes.
You can also browse our heating and cooling systems.
Air Conditioning Vs Heat Pump
The terms air conditioning and heat pump can be confusing because many systems use similar technology.
A traditional air conditioner is often thought of as a cooling product. A heat pump is often thought of as a heating product. In reality, many modern air conditioning systems are air to air heat pumps because they can move heat in both directions.
The difference is usually in the intended use.
Air to air air conditioning systems heat or cool the air in a room. Air source heat pumps for central heating usually heat water for radiators, underfloor heating and domestic hot water.
So, if you want to cool and heat one room, a wall mounted air conditioning system may be the right option. If you want to replace a boiler and heat an entire home plus hot water, an air source heat pump may be more relevant.
Read our guide to whether air conditioning units and heat pumps are the same thing.
You can browse our air source heat pumps.
Air Conditioning Efficiency Explained
Efficiency is one of the most important parts of buying air conditioning.
The main terms you may see are SEER, SCOP, COP, energy rating and inverter technology.
SEER relates to cooling efficiency across a season. A higher SEER rating generally means better cooling efficiency.
SCOP relates to heating efficiency across a season. A higher SCOP rating generally means better heating efficiency.
COP means coefficient of performance. It compares useful heating or cooling output with the electricity used to produce it.
Inverter technology allows the system to vary its output instead of constantly switching fully on and off. This can improve comfort and help reduce wasted energy.
Energy ratings help compare products, but they should not be the only factor. The right system for the room, correct sizing, suitable installation and sensible use all affect real world performance.
For a full explanation, read our guide to EPC ratings, SEER, COP and efficient AC heat pumps.
You can also browse our low running cost air conditioning systems.
DIY Or Professional Installation?
Some air conditioning systems are designed for DIY or simplified installation, while others require professional installation.
Portable air conditioners are usually the easiest because they do not need permanent installation. You still need to set them up correctly, especially the exhaust hose and window vent.
DIY and easy fit systems can suit confident users or tradespeople, depending on the product and installation requirements.
Traditional split systems, multi split systems, ceiling cassette systems and ducted systems usually require professional installation and commissioning. In the UK, work involving F Gas refrigerants is regulated, so it is important to use the correct qualified person where required.
Professional installation is usually best when you want a neat finish, correct sizing, compliant installation, good outdoor unit placement and peace of mind.
DIY may be suitable when the product is specifically designed for it and you are confident the installation requirements match your property.
Read our guides to DIY air conditioning vs professional installation and F Gas regulations and safety standards for UK AC installation.
Do You Need Planning Permission For Air Conditioning?
Planning rules can depend on the property, location, system type, outdoor unit position and whether the building is domestic or commercial.
For many homes, the outdoor unit is the main consideration. Noise, appearance, position, boundaries and neighbouring properties can all matter.
Before buying a fixed system, it is sensible to check local requirements, especially if you live in a flat, listed building, conservation area or managed development.
For wider context, read our article on planning rule changes for heat pump installation.
Which Air Conditioning Brand Is Best?
There is no single best air conditioning brand for every customer.
The best brand depends on your budget, room type, desired features, installation requirements and whether you want premium design, strong value, smart controls, low noise, heating performance or portable flexibility.
Popular air conditioning brands include LG, Samsung, Mitsubishi, Hitachi, Panasonic, Lux Air, Trotec and other specialist climate control manufacturers.
LG air conditioning is popular for modern design, reliable wall mounted systems and smart control features. You can browse our LG air conditioning systems.
Hitachi is a strong choice for split and multi split systems, especially where performance and reliability are important. You can browse our Hitachi air conditioning systems.
Lux Air offers stylish heating and cooling options for customers who want performance with a premium look. You can browse our Lux Air systems.
Trotec is known for portable and climate control products, making it useful for flexible cooling, dehumidification and temporary comfort. You can browse our Trotec cooling and climate control systems.

Air Conditioning For Businesses
Air conditioning is not just about home comfort. For businesses, it can affect staff wellbeing, customer experience, equipment reliability and how usable the space feels throughout the year.
Best Air Conditioning For Offices
Office air conditioning needs to balance comfort, noise, airflow and control. Staff may be sitting in the same position for long periods, so direct draughts should be avoided.
Wall mounted, ceiling cassette, ducted and multi split systems can all work depending on the office size and layout.
Read our guide to the best air conditioning for offices.
Best Air Conditioning For Restaurants, Cafés And Bars
Hospitality spaces can generate significant heat from kitchens, lighting, customers and equipment. Comfort matters because customers are less likely to relax, eat or stay longer in an overheated space.
Restaurants, cafés and bars may need higher capacity systems, better airflow planning and separate consideration for dining areas, kitchens and staff spaces.
Read our guide to the best air conditioning for restaurants, cafés and bars.
Best Air Conditioning For Gyms
Gyms need cooling, airflow and air quality. People exercising generate heat and moisture, so comfort can change quickly during busy periods.
The right system depends on gym size, ceiling height, occupancy, ventilation and the type of activity taking place.
Read our guide to air conditioning for gyms and fitness studios.
Air Conditioning For Shops, Clinics And Studios
Retail spaces, treatment rooms, salons, clinics and studios need comfort without intrusive noise or strong draughts. Appearance can also matter, especially in customer facing spaces.
Wall mounted systems are often suitable for smaller spaces. Ceiling cassette and multi split systems may be better for larger or divided premises.
For wider commercial advice, read our guide to air conditioning for businesses and planning air conditioning for a new business.
Air Quality, Humidity And Dehumidifiers
Air conditioning can improve comfort by cooling the air and helping manage humidity. Many systems also include washable filters that help capture dust and particles.
However, air conditioning is not the same as a dedicated ventilation system, and it is not always a replacement for a dehumidifier.
If your main problem is damp, condensation, mould risk or laundry drying, a dehumidifier may be a better choice. If your main problem is heat, a cooling system is usually more relevant.
In some homes, both can be useful. Air conditioning can cool a bedroom or living area, while a dehumidifier can help manage moisture in problem areas.
Read our dehumidifier buyer’s guide, our guide to the benefits of dehumidifiers and our advice on maintaining your dehumidifier.
You can also read our business guide on improving air quality.
Evaporative Air Coolers Vs Air Conditioning
Evaporative air coolers are sometimes confused with air conditioners, but they work differently.
An evaporative air cooler uses water evaporation to cool the air. It does not use the same refrigeration cycle as an air conditioner and does not remove heat in the same way.
Evaporative coolers can be useful in some conditions, but they are not usually a direct replacement for air conditioning, especially in humid spaces or rooms where you need precise cooling.
If you want proper temperature reduction, an air conditioner is usually the better option. If you want a simple, lower cost cooling effect and understand the limitations, an evaporative cooler may be worth considering.
Read our evaporative air coolers buyer’s guide.
Common Air Conditioning Mistakes To Avoid
One of the biggest mistakes is buying too small. A system that is underpowered may run constantly and still struggle to cool the room properly.
Another common mistake is choosing a portable unit when a fixed split system would be better. Portable air conditioning is useful, but it is not always the best long term answer.
Some buyers also forget about noise. This is especially important in bedrooms, nurseries, home offices, treatment rooms and meeting rooms.
Another mistake is ignoring heating. If you choose a system that can heat as well as cool, it may be useful for much more of the year.
It is also important not to focus only on purchase price. Installation, running costs, warranty, brand quality, filters, controls and long term reliability all matter.
Finally, do not assume every room needs the same solution. A bedroom, conservatory, office and restaurant may all need different types of air conditioning.
Air Conditioning Maintenance
Air conditioning systems work best when they are looked after.
Basic maintenance includes cleaning or replacing filters, keeping indoor units clear, checking airflow, keeping the outdoor unit free from obstructions and arranging servicing where required.
Portable air conditioners also need regular filter cleaning, correct hose setup and proper storage when not in use.
Split systems, multi split systems, ceiling cassette systems and commercial systems should be maintained in line with manufacturer guidance. Regular servicing can help performance, efficiency, warranty compliance and lifespan.
If a system is not cooling properly, has reduced airflow, smells unusual, leaks water or becomes noisy, it should be checked before the problem gets worse.
Read our guides to preventing portable AC failures and preventing split system AC failures.
When Is The Best Time To Buy Air Conditioning?
Many people only think about air conditioning once a heatwave arrives. By then, demand is higher, popular products may sell quickly and installation availability can be more limited.
The best time to plan air conditioning is often before peak summer. Spring can be a good time to compare options, check installation requirements and choose the right system before temperatures rise.
Autumn can also be a smart time to install, especially if you want a heating and cooling system. Demand may be lower than during peak summer, and the system can then be used for efficient heating during colder months.
Read our guide to why autumn can be a good time to install air conditioning.
How To Choose The Right Air Conditioning System
Start with the room. Is it a bedroom, living room, home office, garden room, conservatory or commercial space?
Then think about how often you will use it. Occasional summer use may suit a portable unit. Daily use is usually better suited to a fixed system.
Next, consider installation. Can you have an outdoor unit? Do you live in a flat? Is the building listed? Is there a suitable wall, roof or external location? Would a water cooled or portable option be more practical?
Then consider comfort. Bedrooms and offices need quiet systems. Conservatories and open plan rooms may need more capacity. Businesses may need better airflow and more robust equipment.
After that, look at running costs and efficiency. A more efficient system may cost more upfront but be better suited to regular use.
Finally, think about long term value. A good air conditioning system should solve the problem properly, not just make the room slightly less uncomfortable for a few hot days each year.
Air Conditioning Buyer’s Guide FAQs
