Energy giants have made around £125 billion in profits on their UK operations since the energy bills crisis started.
Since the start of the American-Israeli war on Iran over £3bn in profits have been made on UK operations, yet there are continued calls from energy industry lobbyists to axe the Windfall Tax.
The total profits generated globally by the firms since 2020 stand at over half a trillion pounds.
Methodology
30 firms were monitored, with 26 making a profit over 5 years. Three have posted losses and one (Adura) is yet to post results. These firms were selected by the researchers to create a cross section of the energy industry and to reflect those most frequently covered in the media.
Data for individual companies is currently being updated.
The data is collated from publicly available company reports and industry sources, with profits adjusted where possible to reflect UK operations.
For multinational businesses, UK profit estimates are based on disclosed proportions of revenue, production, or operating assets attributable to the UK, or on reasonable assumptions using sector benchmarks where disclosure is limited.
The figures are indicative, providing a consistent basis to assess trends in UK energy-sector profitability and its relationship to household energy costs. These measures differ from company to company due to reporting processes and regulatory requirements in different jurisdictions.
In determining which measure of profitability to use, the research has prioritised the measure preferred in the company’s own accounts. The totals declared here include offsetting any losses made by some of the firms in some years of the period examined. 30 firms are monitored, with 26 making a profit over 5 years and 1 yet to post results. These firms were selected by the researchers to create a cross section of the energy industry and to reflect those most frequently covered in the media.
