A study released by the London School of Economics (LSE) estimates that Britain’s record-breaking heatwave in June causes a significant economic loss. The research, reported by multiple outlets, uses survey and related data from almost 2,000 people to assess how extreme temperatures affect daily life, including working hours and sleep. The analysis estimates that about 24 million hours of work are lost during the period, leading to an economic cost of £1.15 billion, which some reports also convert to roughly $1.5 billion. Outlets also note that the heat exposes problems in housing and workplaces as well as stresses on public transport. Several sources add that workers in sectors such as construction and agriculture reduce their hours to cope with the conditions. Overall, the findings link the June heatwave to reduced productivity through time lost at work and associated impacts on rest and wellbeing. The study presents its estimate as a calculation of the economic effect of heat on working time and related functioning during the episode.
