What time should I shut my windows to stop the heat? How to keep cool in summer

Parts of the UK, including Wales, are expected to experience temperatures above 30°C this weekend, prompting advice on managing indoor heat effectively.
This high temperature forecast follows patterns of heat buildup focused westward, leading experts and home advisors to urge caution about opening windows during peak heat hours.
Experts recommend keeping windows shut during the day, especially on south- and west-facing sides, using fans by open windows in the evening to bring cooler air inside, and keeping curtains closed to block sunlight.
Window films that block up to 70% of solar heat and 99% of UV rays provide effective insulation, while checking window seals with a candle or smoke test helps detect drafts and improve energy efficiency.
Following these measures can reduce energy demand on cooling systems, lower bills, and make homes more comfortable as the UK faces recurring spells of extreme heat this summer.
