Liberal Democrats Call for Mandatory Air-Conditioning in New UK Homes

The Liberal Democrats’ “climate-ready” programme would make it a legal requirement for every newly built residence to include air-conditioning or an alternative cooling system. The party also wants mandatory cooling in essential public buildings such as schools and health facilities, arguing that new homes must be “fit for the future” and properly insulated.

Recent heatwaves have triggered a UK Health Protection Agency yellow alert covering much of England and the Midlands, with temperatures in London forecast to reach 32 °C (90 °F). The summer has been unusually dry—July’s rainfall has been only about 5 % of the long-term average across England, dropping to 1 % in the south—raising drought and wildfire risks. The May-June heatwaves produced three consecutive days of red warnings for extreme heat, underscoring the growing vulnerability of British housing to high temperatures.

Industry estimates say the number of UK homes with air-conditioning has doubled over the past three years, reaching roughly 4 million out of an estimated 30 million-plus homes. Polling commissioned by the Liberal Democrats found that 28 % of respondents bought a fan or air-conditioning unit during recent heatwaves, while 26 % reported feeling unwell or faint. An analysis led by Imperial College London linked the May-June heatwaves to about 2,700 excess deaths, with a peak fatality rate of roughly 440 per day; the study estimated that more than 40 % of those deaths would have been avoided without the 1.4 °C of human-caused warming recorded to date.

Tim Farron, the party’s environment spokesperson, said the country is “woefully unprepared for extreme heat” and that developers must be required to build homes that are both well-insulated and equipped with cooling. Housing spokesperson Gideon Amos added that UK homes are now among the smallest and hottest in Europe after previous Conservative governments removed minimum-space standards, urging leaders such as Andy Burnham to support rapid adaptation.

If enacted, the proposal would reshape building regulations, targeting older adults and people with health conditions who are most at risk during heatwaves. It also signals a shift from reliance on passive measures—like increased urban tree planting—to a more direct technological response to the climate crisis, highlighting political criticism of past housing policy decisions.
