Martin Lewis is urging people to prepare for this winter as energy bills are predicted to rise further.
Speaking out on Friday, the money saving expert said we are "heading for a very bleak winter" although it "doesn't feel it now." Appearing on Good Morning Britain, he added that energy bills are predicted to soar by October.
Speaking live on TV, he said: "Let's be under no uncertain terms, what we are facing is potentially cataclysmic, we are talking about millions, if not 10 million people moving into real poverty this winter. The worst winter we have seen, maybe since the 1970s."

Taking to his own social media account, Mr Lewis said he had received the latest price cap predictions as he "felt sick writing this." By October, energy bills on average will be over £3,000, compared to two years ago when the cheapest energy bill was around £800, which will then rise further by January.
He wrote: "Please share - people need to know what's coming to see if they can prepare for it."
In another tweet, the money saving exper t apologised to his followers, writing: "Rough Ready Reckoner based on predicted future price cap... If you pay £100/mth now, from Oct £165, Jan £170.
"If you pay £150/mth now, from Oct £250, Jan £255. If you pay £200/mth now, from Oct £330, Jan £340. If you pay £300/mth now, from Oct £495, Jan £510. I'm sorry."
He went on to warn that from October, a typical energy bill will likely be over a third of an average state pension as he said "more will be needed."
On Friday, Mr Lewis criticised the government for acting too slowly and urged them to act now. He said: "Winter is coming, energy bills are going up on October 1 and we need people in place."
