British firms could be wasting half of their electricity powering offices and shops overnight, according to new figures.

Data from over 6,000 smart meter readings show that nearly 50% of business electricity use happens outside of the traditional business hours of 8am-6pm.

Thermal images of some of Britain’s largest cities such as Manchester (pictured) taken at midnight show just how much is wasted at night, says energy supplier British Gas, which commissioned the research.

It claims £1 in every £2 spent on electricity could be wasted, while some of its customers could save £1,200 on their annual bill just by switching off car parking lights at the weekend.
