Every new UK home should have air conditioning, say Liberal Democrats

The Liberal Democrats have proposed a “climate ready” programme requiring all newly constructed UK homes to be equipped with either air conditioning or alternative cooling systems. The party contends that British housing stock is inadequately adapted to cope with rising temperatures associated with climate change, and argues that such requirements are particularly important for protecting elderly residents and those with health vulnerabilities.

The proposal emerges amid a period of significant heat stress affecting large portions of the country. A yellow alert for elevated temperatures has been issued for multiple regions including the south-east, south-west, east of England, the Midlands, and Yorkshire and the Humber, with forecasts showing temperatures reaching 32C in London. Concurrently, much of the summer has been notably dry, with England receiving only 5% of average July rainfall, dropping to 1% in southern areas, creating conditions conducive to drought and wildfire risk.

Data on current air conditioning adoption reveals that while the number of UK homes with cooling systems has doubled in the past three years, only approximately 4 million of the estimated 30 million-plus homes in the country are equipped with such technology. A poll commissioned by the party found that 28% of respondents had purchased fans or air conditioning units during recent heat episodes, with 26% reporting physical discomfort or illness resulting from the conditions.

Party representatives emphasized the urgency of adaptation measures. Tim Farron, environment spokesperson, stated that Britain is unprepared for extreme heat and called on the government to implement a comprehensive strategy shifting responsibility from households to developers. Gideon Amos, housing spokesperson, noted that UK homes rank among Europe’s smallest and hottest following previous government policies that removed minimum space requirements.

Recent heatwaves have demonstrated the mortality risks associated with extreme temperatures. Analysis led by Imperial College London estimated that heat events in May and June resulted in approximately 2,700 deaths, with peak daily fatalities reaching 440. The analysis indicated that more than 40% of these deaths would not have occurred without the 1.4C of warming attributable to human activity to date.
