To keep people safe as summers get hotter, we must target the physical structure of UK housing. Current subsidies should shift focus from just heating to cooling. This means funding the installation of reflective roofing, external shutters, and improved ventilation systems in older, poorly insulated social housing. Many vulnerable residents live in flats that trap heat like ovens; providing grants for heat-reflective window films and high-efficiency air conditioning could save lives.
Public health agencies also need better data to act. We need localized heat maps that track where elderly or low-income populations live alongside 'urban heat islands.' When heatwaves approach, local councils could trigger welfare checks or open cooled community hubs. These centers provide a physical escape for those living in stifling conditions.
Finally, we must fix the energy poverty trap. Low-income households often avoid using fans or cooling because they fear the electricity bill. Subsidies should cover the upfront cost of energy-efficient cooling technologies and offer direct relief for summer electricity spikes. If we only subsidize winter heating, we leave the most exposed people to suffer through rising summer temperatures.
