Money Saving Expert Martin Lewis has advised the public of a certain period of the day that we shouldn't be operating our washing machines.
Speaking during a segment on ITV daytime show This Morning, the financial guru discussed the best times to use appliances if you want to keep your energy bills as low as possible.
During the segment, Phillip Schofield and Holly Willoughby asked Martin about the looming electrical blackouts Brits are concerned about this winter. The duo said that one caller had a question about switching to an economy-7 meter in a bid to save energy and to try and help the National Grid with electricity surges.
