Martin Lewis has issued a warning over high energy appliances during peak hours.
The Money Saving Expert appeared on ITV's This Morning on Tuesday to answer caller's questions about their finances. Phillip Schofield and Holly Willoughby 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.
The consumer expert warned: "We are looking at energy difficulties this winter. We hope there will not be any blackouts."
