When a UK heatwave hits, the shops sell out of cooling kit within days and prices jump as demand spikes. The good news is that the same fan or air conditioner is often listed by several retailers at very different prices — so a quick comparison before you buy can save you a meaningful amount, especially on the bigger-ticket air conditioners.
This guide walks through every practical way to keep cool at home this summer — from a £20 desk fan to a full portable air conditioner — with live price comparisons across Amazon, eBay, Shark and more, so you can see exactly where each product is cheapest today.
A quick note before we start: the right choice depends on your space. A fan moves air to help sweat evaporate (it doesn't lower the room temperature); an evaporative air cooler adds a cooling mist but needs ventilation; and only a proper air conditioner actually drops the temperature of the room. We cover all three below so you can match the kit to your situation.How to Choose Cooling Kit in 2026
Before comparing prices, it helps to know what each type of cooler actually does:
- Fans — the cheapest and most efficient option. They don't cool the air, but moving air over your skin makes a room feel several degrees cooler. Perfect for most UK summers.
- Evaporative air coolers — draw air through a water-soaked filter to blow out cooler, mistier air. They use far less electricity than air conditioning and need no exhaust hose, but work best in dry heat with a window cracked open.
- Portable air conditioners — the only option that genuinely lowers room temperature. They vent hot air out of a window via a hose, use more power, and cost more upfront — but they're the answer for bedrooms during a serious heatwave.
- Bladeless fans — safer around children and pets, easier to clean, and often quieter, though usually pricier than a bladed equivalent for the same airflow.
- Noise matters at night: if you're buying for a bedroom, look for a low "sleep" or "night" mode and a timer so it switches off after you've drifted off.
1. Tower Fans — Best for Living Rooms
Tower fans are the go-to for living rooms and bedrooms: they're tall and slim, oscillate to cover a wide area, and take up very little floor space. Most come with a remote, multiple speeds and a timer.
At the premium end, the Shark TurboBlade is one of the most talked-about fans of the year — its blade rotates and tilts to direct airflow almost anywhere in the room, even straight up like a ceiling fan. If you want maximum value, a simple 29-inch tower from a brand like Igenix covers the basics for a fraction of the price.
Key Features:- Slim, oscillating design that suits any room
- Remote control, multiple speeds and a sleep timer on most models
- Premium picks like the Shark TurboBlade offer multi-directional airflow
- Best For: Whole-room cooling in living rooms and bedrooms.
2. Pedestal & Standing Fans — Best for Maximum Airflow
When you need to move a lot of air across a larger space, a pedestal fan is hard to beat. The big blades and adjustable height let you direct a strong breeze exactly where you're sitting — ideal for open-plan rooms, home offices and kitchens.
The Shark FlexBreeze is a standout here: it runs from the mains or a rechargeable battery, so you can carry it from room to room (or out into the garden) without trailing a cable. Budget options from HOMCOM and TCP deliver powerful oscillating airflow for far less.
Key Features:- Large blades move more air than a tower fan
- Adjustable height and wide oscillation
- Cordless options like the Shark FlexBreeze go anywhere
- Best For: Powerful cooling in larger or open-plan rooms.
3. Cordless & Outdoor Fans — Best for the Garden
Summer cooling isn't just an indoor problem. Cordless fans let you stay comfortable in the garden, on the patio or anywhere without a socket nearby — and the best ones double as indoor fans when you bring them in.
The Shark FlexBreeze range leads the way: the Pro Mist model adds a fine cooling mist for outdoor use, while the compact TableMate version is built to sit on a garden table or kitchen worktop. Both run cordless on a rechargeable battery and switch to mains power indoors.
Key Features:- Rechargeable battery for true cordless freedom
- Mist function on select models for extra outdoor cooling
- Weather-minded designs for patios and gardens
- Best For: Staying cool outdoors and on the move.
4. Desk & USB Fans — Best for Working From Home
If you just need to keep cool at your desk, a small personal fan is the cheapest and most targeted option. USB-powered models plug straight into a laptop or power bank, while compact oscillating desk fans cover a wider area without dominating your workspace.
These are also the easiest cooling kit to justify — quiet enough for video calls, small enough to tuck away, and inexpensive enough to keep one in every room.
Key Features:- Compact and quiet — ideal for desks and bedside tables
- USB or mains powered, with oscillating options
- Low running cost
- Best For: Personal cooling while working or studying.
5. Evaporative Air Coolers — Best Energy-Efficient Cooling
An evaporative air cooler sits between a fan and an air conditioner. It pulls air through a water-soaked filter (and often ice packs) to blow out genuinely cooler, mistier air, while sipping a fraction of the electricity an air conditioner uses. There's no exhaust hose to fit, so you can move it from room to room freely.
They work best in drier heat with a window slightly open, and many add a humidifier and air-purifying function for year-round use.
Key Features:- Cooler, mistier air than a standard fan
- Far lower running costs than air conditioning
- No window kit or exhaust hose required
- Best For: Eco-conscious cooling without the cost of air con.
6. Portable Air Conditioners — Best for Serious Heatwaves
When the temperature climbs into the 30s and a fan just isn't enough, a portable air conditioner is the only option that actually lowers the room temperature. It vents hot air out of a window through a hose, and many units double as dehumidifiers — useful well beyond summer.
These are the priciest items in this guide and prices swing the most between retailers, so comparing before you buy makes the biggest difference here. Look for the BTU rating to match the unit to your room size: roughly 7,000–9,000 BTU for a bedroom, 10,000+ for a larger living space.
Key Features:- The only kit that genuinely lowers room temperature
- Many double as dehumidifiers for year-round use
- Match the BTU rating to your room size
- Best For: Bedrooms and living rooms during a real heatwave.
7. Bladeless Fans — Best for Families & Quiet Cooling
Bladeless fans hide their mechanism in the base, leaving a smooth open loop that's safe around curious children and pets, simple to wipe clean, and often noticeably quieter than a bladed fan. Many add an air-purifying filter, making them a tidy all-year appliance rather than a summer-only buy.
The Dyson Cool is the best-known name, while brands like Russell Hobbs and Daewoo offer bladeless cooling — some with built-in purification — at a range of price points.
Key Features:- No exposed blades — safer for children and pets
- Easy to clean and typically quieter
- Some models include an air-purifying filter
- Best For: Families and anyone who wants quiet, low-maintenance cooling.
How to Save Money on Cooling This Summer
- Compare before you buy. The same fan or air conditioner is often sold by several retailers at different prices — the price comparisons above show today's cheapest for each product.
- Buy early. Cooling kit sells out and rises in price the moment a heatwave is forecast. Buying before the first hot spell means more choice and lower prices.
- Match the kit to the room. A desk fan for working, a tower or pedestal fan for living spaces, and a portable air conditioner only where you truly need to drop the temperature — over-buying wastes money and electricity.
- Mind the running costs. Fans and evaporative coolers cost pennies to run; air conditioners use far more power. For most UK summers, a good fan is the most cost-effective choice.
Frequently Asked Questions
What's the difference between a fan, an air cooler and an air conditioner?
A fan moves air to help your body cool down but doesn't change the room temperature. An evaporative air cooler blows air through water to make it cooler and mistier, using little electricity. A portable air conditioner is the only one that actually lowers the room's temperature, venting hot air out of a window — but it costs and consumes more.
Do fans actually cool a room down?
Not the air itself — a fan helps sweat evaporate from your skin, which makes you feel cooler even though the room temperature is unchanged. That's why it's worth switching a fan off when you leave the room. For a genuine drop in temperature you need an air conditioner.
What size air conditioner (BTU) do I need?
BTU measures cooling power. As a rough guide, a small bedroom needs around 7,000–9,000 BTU, while a larger living room is better suited to 10,000 BTU or more. Buying too small means it struggles in real heat; too large wastes energy.
Are evaporative air coolers any good in the UK?
They work best in drier heat with a window slightly open to let humid air escape. In those conditions they deliver noticeably cooler air for a fraction of the running cost of an air conditioner. In very humid weather they're less effective, behaving more like a misting fan.
What's the quietest type of fan for sleeping?
Bladeless fans and tower fans with a dedicated "night" or "sleep" mode tend to be the quietest. Look for a low minimum speed and a timer so the fan switches off automatically once you're asleep.
Final Thoughts
Keeping cool this summer doesn't have to mean an expensive air conditioner. For most UK homes, a well-placed tower or pedestal fan is the most cost-effective answer, with cordless and desk fans filling the gaps in the garden and at your desk. Step up to an evaporative cooler for efficient extra cooling, or a portable air conditioner when a real heatwave makes a genuine temperature drop worth it.
Whatever you choose, the same products vary in price from retailer to retailer — so use the comparisons above to find today's cheapest deal before the next hot spell sends demand, and prices, climbing.
