The Bank of England warned last week that the U.K. will enter recession later this year. The expected recession is forecast to be the longest since the global financial crisis.Vuk Valcic | SOPA Images | LightRocket | Getty ImagesA skyrocketing energy price cap and eyewatering rental prices are just two factors contributing to the U.K.’s deepening cost-of-living crisis, described by Legal and General CEO Nigel Wilson as “a tragedy for many, many people.”People are “finding life really difficult with energy prices going up, food prices going up, and a horrible background for many people as they struggle to pay their bills,” Wilson told CNBC’s “Squawk Box Europe” on Tuesday.His comments come as energy bills are predicted to reach over £4,200 ($5,088) per year from January, according to analysis by management consultancy Cornwall Insight. Meanwhile, rent prices are up 11% compared to last year, according to Zoopla, a U.K. property site.Cornwall Insight predicts the January tariff cap will rise by over £650, leaving a typical household paying the equivalent of £4,266 each year for the first three months of 2023.Forecasts for the October 2022 price cap have also increased, rising by more than £200 to give an average bill of £3,582 per year.The price cap, which is set by regulator Ofgem, was at £1,400 per year in October 2021.”While our price cap forecasts have been steadily rising since the Summer 2022 cap was set in April, an increase of over £650 in the January predictions comes as a fresh shock,” said Craig Lowrey, principal consultant at Cornwall Insight.”The cost-of-living crisis was already top of the news agenda as more and more people face fuel poverty, this will only compound the concerns,” he added.A household is defined as being in fuel poverty if it can’t afford to heat or cool the home to an adequate temperature.’A tsunami of fuel poverty’Following the latest energy price cap predictions, the End Fuel Poverty Coalition predicts that 9.2 million U.K. households (28.4%) will be in fuel poverty from Oct. 1, increasing to 10.5 million (32.6%) from Jan. 1. “A tsunami of fuel poverty will hit the country this winter and these latest estimates further demonstrate that the level of support already promised by the government is just a drop in the ocean,” said Simon Francis, co-ordinator of the End Fuel Poverty Coalition.The estimates are also fuelling Don’t Pay UK, a campaign encouraging people to cancel their energy bill direct debits from Oct. 1 if the U.K. Government doesn’t act to reduce costs “to an affordable level.” More than 94,000 people have pledged to strike so far, according to the campaign website.A high street decorated with British Union Jack bunting in Penistone, UK.
