Comparing UK home energy tariffs

Fast answer

Ofgem confirmed that the Ofgem price cap rose to £1,663/yr for a typical dual-fuel direct-debit household — for 1 July to 30 September 2026. The rise is driven by higher wholesale gas prices linked to Middle East conflict: the gas element is up about 24% and electricity up roughly 5%. The cap applies from 1 July to 30 September 2026.

The cheapest 12-month fixed deals on our live panel are typically priced below the £1,663 cap, several with no exit fees — run your postcode through the comparison on this page for today's exact prices.

If you are on a capped standard variable tariff today, switching to a competitive fix now locks in a rate below the £1,663 cap and protects you from further rises. Switching is free, takes about five working days, and you can do it even without a smart meter.

Region-by-region: where switching saves most this summer

The £1,663 figure is a GB average. Ofgem sets different unit rates and standing charges for each of the 14 GB regions. Households in the North West, Merseyside & North Wales, and Northern Scotland tend to pay the highest standard prices, and so usually see the largest cash savings from switching to a competitive fix.

Biggest expected savings

North West, Merseyside & North Wales, Northern Scotland — typically £200–£280/yr off a 12-month fix versus the current cap.

Mid-range savings

Yorkshire, East Midlands, West Midlands, South Wales — typically £160–£230/yr.

Smaller (but still real) savings

London, Southern, South East — typically £130–£200/yr; the standing-charge gap is narrower.

Figures use the confirmed July 2026 cap and a TDCV household. Actual savings depend on your consumption, payment method and whether you switch single fuel or dual fuel.

Common pitfalls when switching around the cap rise

Waiting past 1 July

If you did nothing, your variable tariff rose to the £1,663 cap on 1 July. A sub-cap fix locked in now avoids the jump entirely.

Headline unit rate

Always compare on total annual cost — a low unit rate paired with a high standing charge can be worse than the cap for low users. The cap is a unit-rate cap, not a total-bill cap.

Exit fees

Mid-contract switches can incur exit fees of around £25–£50 per fuel with some suppliers, while others charge nothing. Suppliers must let you leave fee-free in the last 49 days of your fix.

Anchoring to one quarter

The October 2026 cap is expected to rise again as winter wholesale costs feed through, so a 12-month fix below today's cap usually wins over the full year.
