The Government has announced it will remove the windfall tax on oil and gas companies should the price of the commodities continue to fall.
Ministers said that they would slash the current 75% tax on North Sea oil and gas profits back to its regular 40% if prices reach certain levels.
They said they would take the move if the average price of oil fell to or below 71.40 dollars per barrel for two consecutive quarters, and the average price of gas fell to under 54p.
On Friday morning Brent crude oil was trading at 75.38 dollars per barrel. UK gas prices were at around 64p per therm.
Oil and gas prices soared after the Russian president launched a full-scale invasion, bent on taking Kyiv in just three days.
But well over a year later Ukraine is now pushing to take back the territory it lost in the early days of the war, which started in 2014.
The Government said that the windfall tax will remain in place until 2028 as previously planned unless oil and gas prices fall to the levels needed for it to be revoked.
It said that the tax had so far raised £2.8 billion since being implemented.
“While the levy included an investment allowance to encourage firms to continue to invest in oil and gas extraction in the UK, industry has warned that companies are cutting back on investment,” the Government said.
“This puts the long-term future of the UK’s domestic supply at risk, meaning we would be forced to import more from abroad at a time when reliable and affordable energy is a focus for families and businesses.”
It said that the tax will not be removed before 2028 if the Office for Budget Responsibility’s energy price forecasts are accurate.
Gareth Davies, exchequer secretary to the Treasury, said: “It is right that we recover excess profits resulting from Putin’s war and use the money to help people with their energy bills.
“Thanks to the revenue raised from windfall taxes on energy profits, we will have helped save the typical household £1,500 on their energy bill by July.
“While we stepped into help, never again can our energy supplies be at the whim of petrostate despots like Putin.
“That’s why it’s so important that we secure investment in our own domestic supply, protecting the tens of thousands of British jobs that come with it.”
“Energy bills are predicted to remain high and levels of household energy debt are still surging,” he said.
“Any talk of reducing or ending the windfall tax while millions still struggle through the energy bills crisis is premature.
“The Government should keep all options on the table to ensure the funding is available to fix Britain’s broken energy system into the long term.”
Greenpeace UK’s climate campaigner, Georgia Whitaker, said: “The government’s windfall tax on oil and gas companies already contains more loopholes than a block of Swiss cheese. And now they want to scrap it altogether.”
But Offshore Energies UK, which represents the industry, said that it was not enough to restore confidence.
“We’ve always been clear that when the windfall conditions go, the windfall tax should go,” its chief executive David Whitehouse said.
“This is a step in the right direction, but many more will need to be taken to restore confidence to our sector.
“We will now work closely with government and lenders to understand the detail of the measure and its effectiveness at unlocking investment.”
