How the trend for turning front gardens into driveways is adding to night‑time heat

The IndependentIndependentCenter10 hr. ago

Scientists warn that the trend of replacing front gardens with driveways in the UK is contributing to increased nighttime temperatures in cities. This phenomenon, linked to climate change, occurs because impermeable surfaces like asphalt absorb and retain heat, releasing it slowly after sunset and creating a 'urban heat island' effect. According to the Royal Horticultural Society, 55% of UK front gardens are now paved, up from 8% in 2005. Paving reduces evaporative cooling, leading to warmer nights and potentially exacerbating health risks during heatwaves. The shift toward electric vehicles has also encouraged homeowners to pave front gardens to install charging points.

In the UK, warm and humid nights are becoming more frequent due to climate change and other factors. One such factor is the conversion of front gardens into driveways, which increases the amount of hard-surfaced areas in urban environments. According to a 2025 report by the Royal Horticultural Society (RHS), 42% of domestic garden space in the UK is now paved, with 55% of front gardens similarly affected. This trend has accelerated since 2005, when only 8% of front yards were fully paved. Paved surfaces absorb more heat than vegetated areas, contributing to the urban heat island effect, where cities experience higher temperatures than surrounding rural areas. This leads to warmer nighttime air temperatures, especially during heatwaves, and can pose health risks, as seen during the 2018 summer heatwave in London.
