But in recent years, each new heat wave brings a fresh reminder that buying a fan or two simply won’t always cut it.

The study, conducted between Dec 2019 and Jan 2020 in 80,000 homes, found that a UK home with an indoor temperature of 20°C and an outside temperature of 0°C loses on average 3°C after five hours [1].
Why don t houses in the UK have AC?
“We are a heating-dominated country, not a cooling-dominated country,” said Tadj Oreszczyn, a professor of energy and environment at the University College London Energy Institute.

Why is there no air conditioning in England?

This is largely due to a concept known as the urban heat island effect, where concrete buildings and heat-absorbing surfaces amplify the already scorching heat.
Why are British summers getting worse?
As the burning of fossil fuels causes average global temperatures to rise, the range of possible temperatures shifts upward, too, making blistering highs more likely. This means every heat wave is now made worse, to some extent, by changes in planetary chemistry caused by greenhouse-gas emissions.
