The UK may not be known for its extreme heat, but with rising summer temperatures and the increasing frequency of heatwaves, keeping your house cool is becoming a priority. Unlike hotter climates, most British homes are designed to retain heat rather than dissipate it, making it essential to find ways to regulate indoor temperatures effectively.
Here’s a comprehensive guide on the best ways to cool your house down in the UK, covering everything from simple daily habits to long-term home improvements.
1. Block Out the Heat: Keep Sunlight Out
One of the most effective ways to keep your home cool is to prevent heat from entering in the first place.
Use Blinds and Curtains
- Keep curtains and blinds closed during the hottest part of the day (usually between 11 AM and 3 PM).
- Blackout curtains or thermal blinds are particularly effective at blocking heat.
- Reflective blinds or white curtains can help bounce sunlight away.
Use External Shading
- If possible, install awnings, shutters, or external blinds to stop heat from reaching your windows.
- Consider planting trees or climbing plants like ivy to provide natural shade.
2. Improve Ventilation: Let Cool Air In
Proper ventilation can make a massive difference in cooling your home.
Open Windows Strategically
- Open windows during the coolest parts of the day (early morning and late evening).
- Create a cross-breeze by opening windows on opposite sides of your home.
- If your house has a loft hatch, open it to let hot air escape upwards.
Use Fans Smartly
- Position fans near open windows to push hot air out.
- Place a bowl of ice in front of a fan for a cooling effect.
- Ceiling fans should be set to rotate counterclockwise in the summer to push cool air down.
Install Trickle Vents
- If you have modern windows, check if they have trickle vents that allow continuous airflow.
- If not, consider adding small vents to improve ventilation without fully opening windows.
3. Reduce Internal Heat Sources
Many appliances generate heat without you realising.
Switch Off Electrical Devices
- Turn off unused lights, especially incandescent bulbs, which produce heat.
- Unplug devices when not in use, as they emit warmth.
- Avoid using ovens and hobs during the day – opt for cold meals like salads or use a microwave instead.
Limit Hot Showers and Boiling Water
- Steam from showers and kettles can raise indoor humidity and temperature.
- Take cooler showers and use extractor fans to remove warm air.
4. Use Cooling Hacks for Immediate Relief
If the heat becomes unbearable, these quick hacks can provide relief.
Use Cold Water and Ice
- Drape a damp sheet over an open window to cool incoming air.
- Fill a hot water bottle with ice water and place it at your feet while sleeping.
- Place a bowl of ice in front of a fan to create a cool breeze.
Use the Egyptian Method for Sleeping
- Dampen a sheet or towel and use it as a blanket while sleeping.
- Keep a cold, wet flannel by your bedside to dab your skin if you wake up hot.
5. Insulate to Keep Heat Out
While insulation is usually associated with keeping homes warm in winter, it also helps keep heat out in summer.
Install Loft Insulation
- A well-insulated loft prevents heat from the roof from seeping into your home.
- Opt for reflective insulation that deflects heat.
Upgrade Windows
- Double-glazed windows reduce heat transfer.
- Low-emissivity (Low-E) glass coatings can reflect heat away.
6. Use Smart Technology to Stay Cool
Technology can help regulate temperature with minimal effort.
How to Keep Your House Cool in the UK: Best Tips for Beating the Heat
Invest in Smart Thermostats and Cooling Systems
- Smart thermostats allow you to control room temperature remotely.
- Portable air conditioning units can be useful, especially in bedrooms.
Use Dehumidifiers
- Humidity makes warm air feel even hotter.
- A dehumidifier removes moisture, making your home feel cooler.
7. Long-Term Solutions for a Cooler Home
If you’re looking for more permanent solutions, consider these home improvements.
Upgrade Roofing Materials
- Cool roofs reflect sunlight instead of absorbing heat.
- Light-coloured roof tiles can help keep your home cooler.
Install Green Roofing
- A living roof with grass or plants absorbs heat and provides insulation.
- It also improves air quality and helps with rainwater drainage.
Consider Air Conditioning
- While not common in the UK, air conditioning is becoming more popular.
- Portable air conditioners are a cost-effective alternative.
Final Thoughts
Keeping your house cool in the UK doesn’t always require expensive equipment—simple adjustments like using blinds, ventilating strategically, and reducing indoor heat sources can make a significant difference. For those experiencing repeated heatwaves, investing in better insulation, cooling technology, or even air conditioning can be worthwhile in the long run.
By following these steps, you can enjoy a comfortable home, even during the hottest summer days.
