Chancellor Rishi Sunak has introduced a "temporary targeted profits levy" on the unexpected profits of energy companies, U-turning on the Government's previous position.
The 25% tax will apply on the unanticipated profits energy companies have made during the period of high energy prices.
At the same time, the new levy will include a new 80% investment allowance, which the Government said "allows [it] to deliver support to families, while encouraging investment and growth".
Earlier this month, Conservative MPs voted down a Labour motion to introduce a similar tax on oil and gas companies.
The Government hopes the levy will raise about £5 billion of revenue to help fund a new £15 billion energy support package for the people struggling the most during the cost of living crisis.
Sunak said 8 million households would get a one-off "cost of living payment" of £650, directly to people's bank accounts.
The levy will be phased out when the current high prices of energy fall, with a ‘sunset clause' written into the legislation.
Hannah Essex, co-executive of the British Chambers of Commerce, said:
"The sheer scale of the cost-of living crisis facing the British public means the Government is absolutely right to provide additional support to those worst affected."
