UK announces new 25% energy profits levy

Executive summary

On 26 May 2022, the United Kingdom (UK) Chancellor, Rishi Sunak, delivered a statement to the House of Commons setting out the measures the Government will take to address the UK’s cost of living crisis. 

The Chancellor announced a new 25% energy profits levy that will apply from 26 May 2022 and will be charged on the extraordinary profits that oil and gas companies are currently making. The tax will be temporary, and, once oil and gas prices return to historically normal levels, the tax will be phased out. The legislation will also include a sunset clause, which will remove the levy after 31 December 2025. The levy is expected to raise £5 billion this year.

Alongside the new levy, the Chancellor also announced a new 80% investment allowance for the purposes of the levy, similar to the UK’s super-deduction. He suggested the investment allowance would lead to tax relief of more than 91p for every £1 invested. However, it is not yet clear what kind of investment will benefit from the proposed incentive within the energy profits levy, but, in any event, it does not appear that investment outside of UK oil and gas activity will attract the 91.25% relief the Chancellor implied.

Electricity generating firms are not included in the new levy, and the Chancellor said that the Government is urgently reviewing the scale of the extraordinary profits they are making and the appropriate steps to take.

Detailed discussion

Key points of detail that have been released 

The Government has published a factsheet on the levy and the investment allowance which makes the following points:

  • The energy profits levy is an additional 25% tax on UK oil and gas profits on top of the existing 40% headline rate of tax for oil and gas companies (30% ring fence corporation tax and 10% supplementary charge), taking the combined rate of tax on profits to 65%.

  • Companies will not be able to offset previous losses or decommissioning expenditure against profits subject to the levy.

  • No historic losses will be allowed to be carried forward into the levy regime. Loss relief will be available within the energy profits levy, but there will be no cross over to any other ring fence taxes.

  • The tax will take effect from 26 May 2022 – companies with an accounting period that straddles that date will be required to apportion their profits.

  • Additional boxes will be added onto the UK’s corporation tax return (CT600) and companies will be required to submit information on the amount of levy payable. The levy will be included in the three-installment payment regime for large companies – although for accounting periods that straddle the commencement day, the levy payment for that straddling period will be made in the final installment payment.

  • The levy will be legislated for via a standalone Bill to be introduced shortly.

  • If oil and gas prices return to historically more normal levels, the Government will phase out the energy profits levy, and the legislation will also include a sunset clause, effective at the end of December 2025.

  • The new 80% Investment Allowance for the energy profits levy will be available to companies at the point of investment, making it more immediate than the current allowance under the supplementary charge. There will be restrictions on the generation of allowance on the acquisition of an asset which has already been in receipt of allowances in the ring fence. Other capital and investment allowances for oil and gas companies will still be available (see the factsheet for a numerical example). 

Other announcements

The energy profits levy helps pay for a new package of targeted government support to help with the rising cost of living. The UK Government has announced:

  • The Energy Bills Support Scheme has doubled from £200 to £400 for every household. This will no longer be repayable.

  • Six million people on disability benefits will get an extra £150 payment (on top of other payments).

  • More than 8 million people who receive means-tested benefits will get a £650 grant with no repayment.

  • This winter, over 8 million pensioner households will receive a one-off £300 Pensioner Cost of Living Payment.

However, no further tax measures were announced, including a rumored cut in value added tax on energy bills. Instead, the Chancellor said that decisions in relation to promised “tax cuts and reform” will be made in the Autumn.


Today’s news is likely to delay and, in some cases, reduce medium term investment. The immediate effect on the supply chain will add further pressure to reduce capacity just as the UK reaches a point of inflection over the next five years where material opportunities will emerge in renewables. The consequence for the supply chain is that it will be less able to support these projects and more of the work may be sourced from overseas.

A key question to ask at this point is therefore to what extent the sudden increase in tax rate could lead to a level of uncertainty over the future tax regime that means investment previously destined for the UK will be curtailed and directed abroad. The Chancellor will be relying on investors acknowledging that the economy is operating in “exceptional times” and understanding that this is a short-term response that should not be seen as a predictor for the future. In taking a view on this, businesses will be looking to the strength of the sunset clause and a commitment and definite timetable for phasing out the tax.
