London recorded more heat-related deaths than any other area in England and Wales, according to a Financial Times analysis published Wednesday.
The report highlights the growing health impact of rising temperatures across the UK. The Financial Times found that the capital has the highest mortality figures tied to hot weather, though the specific number of deaths was not disclosed in the summary.
The analysis comes amid broader concerns about extreme heat. The Guardian separately reported that extreme heat has been linked to roughly 40,000 deaths in England between 1988 and 2025, a figure it described as a “national scandal.” The Times also noted that heat-related deaths are increasing as hotter summers become more common.
However, cold weather remains a larger killer. The Telegraph reported that three times more people die on Britain’s coldest days than on its hottest. New Scientist added that hot weather in the UK is now nearly as deadly as a cold snap, suggesting the gap is narrowing.
The Financial Times report did not specify which London boroughs were most affected or what demographic factors drove the higher death toll. It also did not break down figures by age, gender, or pre-existing health conditions.
The findings point to a growing public health challenge for UK cities, particularly London, which faces higher urban temperatures due to the heat island effect. The capital’s dense infrastructure and larger population may contribute to the elevated risk, though the report did not confirm these factors.
What to watch next: whether UK authorities introduce new heat-health action plans or building standards in response to the data.
