Millions of people in the United Kingdom are steeling themselves for colossal rises to their energy bills over the next few months, a coda to a year already marked by record price increases. The crisis is not unique to the country. Prices have shot up across Europe since last fall, driven by a spike in demand as countries lifted pandemic lockdowns. Russia’s invasion of Ukraine in late February, and the subsequent drop in Moscow’s oil and natural gas exports to Europe, have pushed prices even higher. But UK energy prices are now higher than in comparable economies like France and Italy, analysts told CNN Business. And Brits have suffered much bigger price increases than in most European countries, including Germany, where decades of energy policy has been turned on its head by the Ukraine war. The Office for National Statistics said this week that UK natural gas prices rose nearly 96% in the year to July, while electricity prices are up 54%. Annual consumer price inflation for gas and electricity in the United Kingdom is forecast to soar to an average of around 80% this year, compared to an average of 40% across the 19 countries that use the euro, analysis from Deutsche Bank shows. The worst is yet to come. Average annual energy bills could exceed £4,000 ($4,820) from January, and £5,000 ($6,000) later in the spring, up from about £2,000 ($2,400) currently. Millions could be forced into poverty as a consequence. Leaders of the UK National Health Service warned Friday of a “humanitarian crisis.” Many people could fall sick this winter as they “face the awful choice between skipping meals to heat their homes and having to live in in cold, damp and very unpleasant conditions,” they said. Overall UK inflation exceeded 10% in July, compared with 8.9% in the eurozone. Unlike other problems in the UK economy, Brexit doesn’t appear to be a major factor. So why are British energy bills rising so much faster than across much of Europe? A broken market As wholesale costs ballooned last year, 31 smaller UK energy companies — who traditionally offered competitive prices — went bust, forcing millions of customers onto the books of bigger suppliers, and to pay higher bills. The way the British government designed the energy market made this more likely, Henning Gloystein, director of energy, climate and resources at Eurasia Group, told CNN Business. Smaller companies were acting like brokers rather than providers of an essential utility. “Many UK retail energy providers weren’t real energy producers. Instead, they bought electricity and gas in the wholesale market and then sold it on to retail customers like households,” Gloystein said. That meant that as soon as wholesale costs increased far above what suppliers could legally charge, they went bankrupt. Europe operates in a different way. Most countries have tighter regulations on suppliers, Gloystein said, including rules designed to shield them from sudden price spikes. The prices UK households pay are subject to a cap, but it is adjusted every six months — a period about to be cut to three — meaning bills rise more quickly in line with wholesale costs. “There’s a transitional arrangement between now and when we move to that full quarterly model that’s pushing up prices a little bit more,” Sanjay Raja, Deutsche Bank’s chief UK economist, told CNN Business. “Suppliers are able to pass on the increases in wholesale gas prices a lot more quickly than they were in the past,” he added. Lack of storage The United Kingdom has faced a “perfect storm” of events which have bumped up energy bills, according to Raja. Most homes are supplied with natural gas, he said, whereas electricity, nuclear energy and renewable sources make up a bigger share of the energy mix across the European Union. The country also relies on gas to generate 40% of its electricity, compared to less than one fifth for the bloc as a whole, according to Deutsche Bank. “It’s a double whammy effect and the UK’s overdependence on gas is a big reason why gas prices I think in the UK are a little bit more elevated than elsewhere,” he said. While the United Kingdom produces about half of its gas, North Sea output last year fell to its lowest level on record due to maintenance work, according to the government’s business department. A lack of storage has exacerbated the situation. Centrica\n \n (CPYYF), a UK energy company, closed the largest gas storage facility in the country in 2017, though it is in discussions with the government to reopen the site this winter. Europe has more storage capacity, and has been rapidly filling it ahead of winter — and a feared total cut off of Russian gas. UK natural gas contracts for next year’s first quarter are nearly 7% more expensive than European benchmark contract prices, according to analysis by Auxilione. That’s because Europe has now built a buffer for the winter months. The lack of storage forces the the United Kingdom to rely on “real-time flows” of gas from the North Sea, Norway, Belgium, as well as liquefied natural gas imports, Tony Jordan, director at Auxilione, told CNN Business. “We’re much more reliant on the here and now when it gets to winter,” he said. Europe’s gas is still eye-wateringly expensive. It was trading at €242 ($244) per megawatt hour on Friday, an all-time high, according to Auxilione. That’s much higher than the spot price for UK gas, which is trading at an equivalent of €160 ($161) per megawatt hour, but the differential is driven mostly by greater demand in Europe as it fills up its tanks for winter. Germany declared a gas crisis in June after Russia cut flows through the vital Nord Stream 1 pipeline by two-thirds, bringing the country one step closer to rationing gas to industry. Minimal government support Faced with soaring bills, governments across Europe have stepped in to help ease the financial pressure on households. But the “elephant in the room,” said Raja, is that none of the support offered by the UK government so far has directly subsidized consumer energy prices. Earlier this year, the government announced a £150 rebate on a local tax for millions of households to help ease the pain. More help is coming soon, but it won’t be anywhere near enough, according to anti-poverty campaigners. In May, the government announced a £15 billion ($18 billion) package of support, including a £400 ($482) credit to 29 million households from October, which will be spread over six months. By comparison, France has capped electricity price increases to 4% until the end of the year. Other countries “have had more direct intervention when it comes to energy prices, so comparatively UK gas and electricity prices are running a little bit higher,” Raja added. On Thursday, Germany announced plans to slash a sales tax on gas to 7% from 19% until March 2024, which is designed to more than offset new levies introduced to pay for gas storage. The government has asked companies to pass the reduction onto their customers, according to a report by German broadcaster ZDF. Liz Truss, the favorite to succeed Boris Johnson as the UK’s next prime minister next month, has not said how she would provide further help to households beyond cutting taxes. The opposition Labour Party is calling for a windfall tax on the profits of oil and gas companies to be extended to help fund a freeze on energy bills this winter. — Mark Thompson contributed reporting.
