Martin Lewis issues warning to anyone with a washing machine | Personal Finance | Finance

The National Grid has said this is the period that a blackout is most likely to happen especially on a “really, really cold day”.

Martin went on to say that Britons should avoid, where possible, turning on their washing machines or tumble driers during this time in a bid to help each other out.

He added: “Let’s all try not to put stuff we don’t need to put on between 4pm and 7pm.

“If we can avoid using lots of energy between 4pm and 7pm and it makes no difference to our lives, then we should all be somewhat conscious of that, whether or not it’s cheaper, because it will collectively help us all.”
