Side-by-side charts from 1970 to 2025. Left: stacked area chart of inland energy consumption by primary fuel (%), where coal, petroleum, natural gas, bioenergy and waste, nuclear, renewables and net electricity imports combine to the total; fossil fuels' share falls as coal declines and renewables grow. Right: line chart of energy intensity (tonnes of oil equivalent per real GDP) and net imports (% of inland consumption); energy intensity falls, while the UK moves from net importer to exporter and back to net importer.
The recent rise in global energy prices represented a negative terms-of-trade shock for the UK, but was smaller than the 2022 shock and occurred against a backdrop of greater spare capacity. In this box, we explored how changes in the UK’s energy mix and intensity, reliance on energy imports, the pass-through of wholesale prices, and underlying economic conditions affect the impact of energy price shocks.
Side-by-side stacked bar charts of the impact of mergers and acquisitions on losses used and receipts from 2026 to 2031 (£ billion). Left panel, losses used impact: blue = completed mergers; yellow = allowance for possible future mergers; black diamonds = total impact from mergers. Positive impacts are largest in 2026 and 2027, fall in 2028, turn negative in 2029 and 2030, and remain slightly negative in 2031. Right panel, receipts impact, 2026-27 to 2031-32: the same legend applies; impacts are negative through 2028-29, slightly positive in 2029-30 and 2030-31, and near zero in 2031-32.
Recent merger activity has enabled companies with a large stock of historical tax losses to combine operations with profitable tax-paying companies, allowing greater use of losses against taxable profits. In this box, we explored how mergers affected the use of tax losses and the impact on the oil and gas receipts forecast.
Chart 2B: Line chart and stacked bar chart showing CPI inflation in the adverse scenario
As tensions have risen in the Middle East, there has been increasing concern over the possibility of a wider escalation in the region and its implications on the UK economy. In this box we considered the economic growth and inflationary implications of an adverse scenario. In this scenario, supply chain disruption reaches levels not seen since the pandemic levels and energy costs rise sharply for a second time since the pandemic.
Chart 3A: Energy consumption and gas supply
Since 1970 the UK's energy sector has undergone significant shifts following the discovery of oil and gas in the North Sea and the energy shocks of the 1970s. In this box we summarised the historical events and changes that has led to the UK has become increasingly dependent on imported gas.
Chart 3B: Illustrative enhanced levelised costs of energy
An estimate of the full cost of different energy sources to the power system needs to reflect more than just the construction and operating costs of energy generators that are captured in the levelised cost of electricity (LCOE). In this box we explored enhanced measures of levelised costs of energy.
