Ministers have denied being complacent over 18-month-old warnings about risks to the UK’s energy supply after 1.5 million people were left without a provider.
A host of suppliers have gone to the wall in recent weeks after the energy sector was hit by rocketing global wholesale gas prices.
With 800,000 consumers losing their suppliers on Wednesday alone, two energy companies have since looked to make it more difficult for new customers to sign up for their services as they attempt to survive the current turbulence.
Bulb scrapped its popular refer-a-friend scheme as it tries to raise new cash, while rival Ovo Energy changed its website by removing an invite to “get an energy quote in under two minutes”.
It comes as Labour used an urgent question to drag Business Secretary Kwasi Kwarteng before MPs to face questions over the crisis.
Shadow business secretary Ed Miliband quoted a letter from energy regulator Ofgem warning of a “systemic risk to the energy supply as a whole” which had been sent 18 months ago.
Opposition leader Sir Keir Starmer tweeted that the details showed the Government was “warned about a looming crisis and didn’t prepare”.
Speaking in the Commons, Mr Miliband accused ministers of being “complacent” about the shock that rising gas prices could wreak upon the market, as well as families and the cost of living.
But Mr Kwarteng said the Conservative administration had “not been complacent” as suppliers collapsed.
The Cabinet minister said that Ofgem’s concerns had been “interrogated” during the coronavirus pandemic, with the supplier of last resort programme, where consumers are automatically transferred to a new provider if their supplier exits the market, was “found to work”.
A basic duty of government is to ensure secure and affordable energy supplies for households and businesses. The Tories were warned about a looming crisis and didn’t prepare. https://t.co/tRH9slOVKw

It comes as a minister in Mr Kwarteng’s department admitted the energy price cap is under “pressure” due to crippling energy prices.
But Paul Scully said it would be up to the energy watchdog to decide if the cap, which he said is saving dual-fuel energy customers around £100 per year, should rise.
The cap is currently due to next be reviewed in April.
The business minister told Sky News the Government was “planning for the worst-case scenario” which he said was that gas prices would remain high beyond a “short spike”.
Both Mr Scully and Mr Kwarteng repeated the assertion on Thursday that the energy price cap would remain and that they did not want to bail out firms on the brink of failing.
