Together Energy has become the 26th energy company in just five months to be buried under the weight of soaring gas prices.
The business has exited the market, regulator Ofgem said, leaving its 176,000 household customers without an energy supplier.
Ofgem has taken on the job to find them a new home with one of Together’s rivals.
The firm also owned Bristol Energy, Ofgem said.
“Ofgem’s number one priority is to protect customers,” the watchdog’s head of retail Neil Lawrence said.
“We know this is a worrying time for many people and news of a supplier going out of business can be unsettling,” said the regulator’s head of retail Neil Lawrence.
“I want to reassure affected customers that they do not need to worry.
“Under our safety net, we’ll make sure your energy supplies continue.
“Ofgem will choose a new supplier for you and, while we are doing this, our advice is to wait until we appoint a new supplier and do not switch in the meantime.
“You can rely on your energy supply as normal.”
It is now a well-rehearsed statement from Ofgem, which has so far managed to find new homes for all energy customers left in the lurch by a failing supplier except Bulb, which had so many customers that Ofgem and the Government feared no other supplier could step in without being at risk themselves.
Bulb was granted a £1.7 billion loan from the Government and is being run under special administration.
Energy companies were the first to feel the force of the rising gas price. Some had prudently bought much of their gas in advance, but those that had not were squeezed between the rising prices and the cap on what they can charge consumers.
However, in April that cap will be changed so the pain will then be passed from suppliers to their customers.
Where the cap will be set is still to be decided, but analysts believe it could reach around £2,000 per year for an average household – more than £700 higher than today.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
