As a London-based property maintenance company, we know how rare but intense UK heatwaves can be in the capital city which seems to lock in the heat!
Many homes in London aren’t built with extreme heat in mind, which can make even a few days of high temperatures feel unbearable. Whether you’re in a Victorian terrace, a modern flat, or a converted townhouse, here are some tried-and-tested ways to keep your home, and yourself cool when the mercury rises. 🥵🥵
1. Block the Sun, Not the Breeze
Sunlight pouring through windows may look lovely, but it also raises the temperature indoors.
- Close curtains or blinds during the hottest parts of the day (typically 11am–4pm). Blackout or thermal blinds are ideal, but even light-coloured sheets will help reflect heat.
- Open windows strategically: Ideally, early in the morning and later in the evening when outside air is cooler. Create cross-ventilation by opening windows on opposite sides of the home.
2. Turn Off the Heat Sources
Many appliances produce heat, even when not in use.
- Switch off electronics and lights you’re not using, especially incandescent bulbs.
- Avoid using the oven or hob, opt for microwave meals, salads, or BBQs if you have outside space.
- If you’re in a flat or terrace, remember that upstairs heat rises, so try to keep activity and appliances downstairs where possible.
3. DIY Cooling Hacks for Your Home
These simple techniques can make a surprising difference.
- Place a shallow bowl of ice in front of a fan to circulate cooler air (think of it as a mini DIY air conditioner).
- Hang a damp sheet in front of an open window: The breeze will pick up moisture and cool the air slightly.
- Use foil or reflective film on south-facing windows to deflect intense heat.
4. Stay Cool Personally – Health Comes First
Keeping your body temperature down is just as important as cooling the room.
- Drink plenty of water: At least 2 litres a day, and more if you’re sweating.
- Wear light, breathable fabrics such as cotton or linen, and avoid dark colours.
- Take cool showers or baths to lower your body temperature before bed.
- Use a damp flannel on your neck or wrists, or freeze a hot water bottle filled with cold water for an instant cooling pad.
5. Consider Long-Term Solutions
If heatwaves become more frequent (and they might), it’s worth investing in more permanent fixes.
- Install ceiling or wall-mounted fans, or look into portable air conditioning units.
- Add thermal or UV-reflective window film to reduce indoor heat gain.
- Consider external shading options like awnings or shutters.
- Have your insulation and ventilation systems checked: As a property maintenance company, we often find that poor airflow contributes to excessive indoor heat.
