Financial expert Martin Lewis has cleared up advice about the best time to use your washing machine and other electronic devices to keep energy bills low.
He told viewers on ITV This Morning that it would make no difference - for most of us - and explained you would only get cheaper energy at night if you were on a 'time of use' tariff.
The Money Saving Expert said the "vast majority" of people were actually on a different tariff which meant it would cost them the same amount to use energy no matter what time of day.
