The government is considering offering emergency state-backed loans to energy companies as firms battle to stay afloat amid surging gas prices.
Smaller suppliers face ruin as price hikes have made their price promises to customers undeliverable.
The process for dealing with failing firms is under pressure as adopting customers has become unattractive for surviving companies due to price rises.
The loans are expected to be offered to encourage firms to take on customers.
Boris Johnson, who is in New York ahead of a White House visit, told reporters that the squeeze on gas supply and supply chains was a global problem and was “temporary”.
He said he was “very confident” in the UK’s supply chains and that market forces should be “very, very swift” in fixing the issues, but added government would help where it could.

Several energy suppliers are batting to stay in business, with the UK’s sixth largest energy company Bulb seeking a bailout to stay afloat.
Four other smaller firms have ceased trading in recent weeks, and four more are expected to go out of business next week.
The proliferation of new energy retailers, set up to challenge the bigger players, had been considered by past and present governments as a triumph of competition in a competitive market.
The bigger energy providers have the financial resources to take out insurance – or hedge – against the risk of a spike in energy prices. Smaller players have been unable or unwilling to spend the money to guard against a price shock.

Industry sources have told the BBC that the insuring positions or “hedges” – the right to buy energy at historic fixed prices – taken out by the bigger players, are now worth as much or more than the big companies themselves.
Senior executives at some of the largest companies said the energy price cap – supported by both Labour and Conservative politicians – had played a part in bringing about the current crisis.
“You can legislate to protect the consumer – but that can bankrupt the supplier,” said one senior industry source.
“The price cap is now the cheapest deal in the market and providing new customers with energy at that price is loss making.”
The BBC also understands that levies on customers’ energy bills intended to fund green initiatives will be maintained as the sums involved will not significantly address the scale of the current problem.
