Forecast — based on Cornwall Insight, EDF and E.ON predictions as of April 2026. Confirmed figure added 27 May.
Why is the price cap going up?
Tensions in the Middle East — particularly the standoff between the US and Iran — pushed wholesale gas prices to levels not seen since late 2023. When gas becomes more expensive to source, the cost flows through to every UK household on a standard tariff.
UK electricity prices are closely tied to gas prices, even if you have an electric boiler or hob. That’s because gas-fired power stations still set the market price for electricity across the national grid. When gas goes up, so does your electricity bill.
The Ofgem price cap isn’t calculated on today’s prices — it uses a rolling average of wholesale costs over the previous three months. This means a price spike in February and March will lock in higher bills from July, even if prices have calmed down by the time you see the change on your statement.
