Source: Ofgem energy price cap history. Plotted on the pre-2026 Typical Domestic Consumption Values basis throughout for a like-for-like comparison — Ofgem revised its assumed usage figures in mid-2026, which produces a second, lower parallel figure for the last two quarters that isn’t shown here to avoid mixing bases.

Only the UK has a clean, directly-sourced multi-quarter price history among the 5 countries this site covers — Australia’s Default Market Offer has a comparable 4-year annual trend (shown on the Australia energy costs page), but Ireland, the US and Canada don’t publish an equivalent single-figure historical series. This is not financial advice.
