Every new UK home should have air conditioning, say Liberal Democrats
The Liberal Democrats are calling for air conditioning to be made mandatory in all new UK homes, arguing the country's housing stock is "woefully unprepared" for the extreme heat brought by climate change. The party also wants cooling systems required in essential public buildings such as schools and hospitals, alongside passive measures like planting more trees in residential areas. The proposal comes as a UK Health Protection Agency yellow heat alert covers much of England, with London expected to reach 32C, and follows a summer marked by severe drought and wildfire risk.
Currently only about 4 million of the UK's 30 million-plus homes have air conditioning, although this figure has doubled in the past three years. Lib Dem polling found 28% of people bought a fan or air conditioning unit during recent heatwaves, and 26% said the heat had left them feeling unwell or faint. The party cited an Imperial College London analysis estimating that May and June heatwaves killed around 2,700 people, with more than 40% of those deaths attributable to human-caused global warming, as it urged the government to set new building rules for developers.
In short
- Lib Dems want air conditioning compulsory in all new UK homes
- Only 4m of 30m+ UK homes currently have air conditioning
- Recent heatwaves linked to roughly 2,700 UK deaths, study finds
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Mandatory air conditioning addresses a genuine public health emergency, with climate-induced heat waves now killing thousands annually, particularly amongst vulnerable populations. Since homes built today will stand for decades through increasingly severe weather, establishing cooling as a building standard is both preventive and cost-effective compared to retrofitting later.
The case against
Mandating air conditioning would substantially increase new house prices when housing affordability is already critical, potentially pricing families out of ownership. Whilst public health is vital, more targeted approaches—improving passive cooling design and providing focused support for vulnerable populations—could address safety concerns without imposing blanket costs that worsen the housing crisis.
Explained simply
The UK's housing is poorly equipped to deal with extreme heat. Currently, only about 4 million of the country's 30 million homes have air conditioning, though this number has doubled in just three years. Recent heatwaves and heat alerts have highlighted concerns about how people will cope with rising temperatures.
The Liberal Democrats have proposed that all new homes built in the UK should be required to have air conditioning systems installed. They also want cooling systems made mandatory in essential public buildings such as schools and hospitals, alongside other measures like planting more trees in residential areas to provide natural cooling.
This proposal is rooted in evidence of heat's impact on public health. An analysis cited by the party estimated that heatwaves in May and June caused around 2,700 deaths, with a significant portion linked to human-caused climate change. Polling also shows that roughly a quarter of Britons bought cooling devices during recent heatwaves, and a similar proportion reported feeling unwell from the heat, suggesting widespread public concern about the problem.
