Latest energy tariffs released

Last updated: 06/09/2025

August saw a renewed push from suppliers to attract customers ahead of the next energy price cap update. Ofgem has now confirmed that the cap will rise to £1,755 from 1 October 2025, up 2% (£35) from the current level of £1,720. While this change reflects rising wholesale costs, typical bills remain stubbornly high by historical standards.

At the same time, the UK’s energy mix continues to fluctuate with lower wind generation and strong solar output shaping supply across the grid.

With colder months approaching and energy costs set to rise again, locking in a fixed energy tariff now could help households avoid future hikes and bring much-needed budgeting certainty through winter.
