Martin Lewis was left well and truly baffled after Edwina Currie offered up a bizarre tip for saving energy amid the ongoing cost of living crisis.

From warnings over air fryers to avoiding certain credit schemes, the Money Saving Expert boss has been on hand to offer the nation all kinds of tips and tricks on how to save cash during this difficult period.

But even he has admitted to being at a loss of what to do, with costs going beyond the scope of anything the UK has experienced before.

And back in September during an episode of Good Morning Britain, he appeared to be in despair as Edwina - who served under Margaret Thatcher's government - offered up an interesting tip to save some cash.

In a clip shared on Twitter, she held up a square of foil-lined insulation and said: "Here's one of my suggestions as a tip, something that is dirt cheap.

"Martin knows about this sort of thing. If you put some of this behind your radiators, it really works, it makes the whole room nice and warm and it means you can turn down your thermostat without it causing you any more discomfort.

"Martin, Susanna, most people my age have lived in houses without central heating but we are dependent on it now.

"Just that kind of little thing makes such a difference."

She added: "Moving the sofa away from the radiator, you don't want to be heating the sofa, you want to be heating the room."

Martin's reaction says it all.

Dozens of people responded to the 'tip' with a similar level of apprehension, with one writing on Twitter: "We all grew up in houses without central heating...' what an entirely useless statement.

Although a few people defended the former Tory politician, others were on hand to explain why tips such as foil-lined insulation aren't going to help in the way UK households need it to.

"They're tips that are going to make savings of a tiny percent, when bills are going up 80 percent," wrote one. "We're so far beyond 'tips' it's laughable that people think this is a solution."
