Key highlights of this paper by the UK Government are:
In the third quarter of 2025 total production was 21.2 million tonnes of oil equivalent, 2.5 per cent lower compared to the third quarter of 2024 and at the lowest quarterly total this century. Oil and gas production rose marginally last year, but both remain significantly below pre-pandemic levels. Low carbon output fell by 8.4 per cent as a result of record low nuclear output due to refuelling and continued outages.
Total primary energy consumption for energy uses fell by 3.6 per cent, with record low quarterly demand from nuclear generators the main driver for the fall in consumption. When adjusted to take account of weather differences, primary energy consumption fell by 3.4 per cent in the same period last year.
Total final energy consumption was 2.6 per cent lower compared to the third quarter of 2024. Domestic consumption fell by 4.6 per cent with July and August 2025 notably warmer than a year earlier, whilst services consumption rose by 0.3 per cent. Despite manufacturing output remaining above pre-pandemic levels, industrial consumption fell by 5.4 per cent to the lowest quarterly total this century. Transport consumption fell by 1.9 per cent with petrol, jet and diesel all falling in the same period last year. On a seasonally and temperature adjusted basis, final energy consumption fell by 1.4 per cent, with rises in domestic and services but falls in industry and transport consumption.
In the third quarter of 2025 dependency on fossil fuels was 72.6 per cent, up 0.5 percentage points on the same quarter of 2024. The low carbon share was 23.6 per cent in the third quarter of 2025, down 0.7 percentage points on the same quarter of 2024, due to the fall in nuclear output.
