Cooling Down UK Homes: Expert Tips for Reducing Heat Waves

Topic: Environment

UK experts are redesigning homes to cope with hotter temperatures. They're testing external shading devices that can reduce indoor temperatures by over 6°C. This is crucial as the UK plans to build 1.5 million new homes by 2029.

The UK is experiencing its third heat wave of 2026, and most people want to stay cool at home. To address this issue, building regulations were introduced in 2022. These regulations require architects to check if new homes might be at risk of overheating during the design stage.

Around 4.6 million bedrooms (19% of the stock) and 3.6 million living rooms (15%) in England's homes were found to have overheated during the summer of 2018. To combat this, researchers at Loughborough University are experimenting with semi-detached houses fitted with different shading devices.

The study has shown that external shading can reduce indoor temperatures by over 6°C, which can make a significant improvement in people's health and well-being at home. Other research is exploring how affordable and acceptable these shading devices are to householders.
