As well as this, the savings app found that for a family of four, who each use a 40w fan in their room at night instead of an air conditioning unit, would add an extra £11 per month to their energy bill.

Furthermore, using an extra fridge in summer to cool drinks and food cool over the three-month period could add an additional £25.

Despite families not having to put the heating on in summer, they could still see their energy bills go up £9 a day by using cooling devices, according to Loop.

Steve Buckley, the head of data science at Loop, shared how monitoring energy usage via smart meters is the “key to making savings”.
