Source: Ofgem, 27 May 2026. New cap runs 1 July to 30 September 2026.
Why is the price cap going up?
Ofgem says the 13% rise is being driven by higher wholesale gas prices — up around 28% over the three months that fed into this cap calculation, mostly because of ongoing conflict in the Middle East. Gas bills rise by about 24%; electricity bills rise by about 5%.
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. The price spikes that fed into this calculation have now locked in higher bills for July to September, even if wholesale prices have eased since.

Figures are based on Ofgem’s confirmed July 2026 price cap, announced 27 May 2026. We use the apples-to-apples typical bill (£1,641 → £1,862, the same benchmark Ofgem applied last quarter); Ofgem’s separately published “new typical bill” of £1,663 uses updated consumption assumptions and isn’t comparable like-for-like. Per-kWh figures derived from Ofgem’s announced percentage changes; we’ll refine when Ofgem’s resource pack publishes exact rates. BillLuma is not affiliated with Ofgem or any energy supplier.
