Summer has arrived early this year, with Europe already sweltering under record-breaking temperatures.

In France, the mercury peaked at 37°C, a first for May, while the UK also broke its monthly record, with temperatures reaching 34.8°C in London. The same goes for Ireland, with an unprecedented 30.5°C.

Nonetheless, the majority of EU citizens, 68%, don't have air conditioning (AC) or fan systems at home, according to a European Environment Agency report entitled "Overheated and Underprepared".

Which countries struggle the most to afford AC?

While some countries may not need it — Europe isn't equally hot everywhere — more than one in three people (38%) say they are unable to afford AC.
