While it feels hot enough outside, it can actually often get a lot warmer inside your home during a heatwave.

On June 25, which was one of the hottest days of the year, the maximum indoor temperature recorded was much higher than the maximum outdoor figure.

In the east of England, it reached 31.9C, but hit 45.9C inside, according to data obtained by smart thermostat company tado°.

In London, meanwhile, it reached 30.8C outside and 44.9C inside.

One of the major reasons why it gets warmer indoors compared with outside is because of your indoor appliances.

Appliances that give off heat when running include televisions, dishwashers, stoves, refrigerators, as well as irons and kettles, according to Home Energy Extension.

Christian Deilmann, co-founder of tado°, said: "We often concentrate on the temperatures outside but our data shows just how much the inside of your home or workplace can heat up and severely impact wellbeing and even your health.

"With the UK Health Security Agency putting an amber warning in place this week, not only people older than 65 or with medical conditions should think about the inside environment as well as outside."

It will reach as high as 32C on Thursday, with plenty of blue skies and sunshine throughout the day.
