Energy bills for the average household will be frozen at no more than £2,500 and businesses will be spared crippling increases as Liz Truss took action to shield Britons from the global gas crisis.
The Prime Minister’s two-year plan paid for by tens of billions of pounds of borrowing will save the typical household around £1,000 from October and protect billpayers from further expected rises over the coming months.
For businesses and other non-domestic users such as schools and hospitals, which have not been covered by the existing price cap, a six-month scheme will offer equivalent support.
The plan will see the Government limit the price suppliers can charge customers for units of gas, replacing the existing price cap set by regulator Ofgem.
Ministers will provide energy suppliers with the difference between the new, lower price and what they would charge were this not in place.
The Prime Minister told MPs: “This is the moment to be bold. We are facing a global energy crisis and there are no cost-free options.”
Downing Street has refused to put a cost on the programme, previously estimated to cost up to £150 billion. The Prime Minister’s official spokesman would only say the price will be “tens of billions”.
Instead it will be paid for by borrowing, with Ms Truss promising Chancellor Kwasi Kwarteng will give specifics during his emergency fiscal announcement later this month.
Paul Johnson, the director of the Institute for Fiscal Studies think tank, criticised the lack of transparency, tweeting: “This is one of the biggest announcements in peacetime history, and apparently we’ll be told how much (it costs) in a few weeks.”
His deputy director at the think tank, Carl Emmerson, suggested the cost of the scheme could be more than £100 billion in the first year alone.
Labour leader Sir Keir Starmer said Ms Truss’s refusal to fund the plans with a windfall tax is “driven by dogma” and will mean “it’s working people who will pay for that”.
Under the current domestic energy cap, households face average bills of £1,971 but this was set to rise to £3,549 in October – and forecasts have suggested it could hit as high as £7,700 by April 2023.
The £2,500 “energy price guarantee” will apply in England, Scotland and Wales from October 1, with the same level of support made available to Northern Ireland, which has a separate energy market.
The guarantee is based on the existing cap, plus the already promised £400 energy bills discount for all households, meaning costs will be similar to those faced today.
Green levies worth around £150 a year on average will be temporarily removed from household bills, lasting for two years.
This could see domestic shale gas production begin in as little as six months, but will face heavy criticism from opponents who have long warned that fracking can cause earthquakes, water contamination, noise and traffic pollution.
Ms Truss told MPs that fracking would only go ahead in areas where there was local support for it.
And she outlined a goal of making the UK a “net energy exporter by 2040” with her plans on fracking, nuclear and the acceleration of renewables.
The debate turned sombre as concern for the Queen spread through the Commons as it emerged she was placed under medical supervision at Balmoral.
Meanwhile, the pound rose against the dollar as Ms Truss outlined her strategy, after sterling dropped to a 37-year-low against the US currency amid concerns over borrowing costs.
