A new study by tado° has found that UK & Irish homes have the coolest indoor summer temperatures in Europe. The study was conducted in 150,000 European homes from June – August 2019 between 12 – 6pm. It shows an average indoor temperature of 22.3ºC and 21.5°C in UK and Irish households respectively. This means that the UK and Ireland are the only European countries studied that fit within the World Health Organisation’s ideal indoor temperature recommendations of between 18º and 22º (depending on the room function) (1).
