The August 2026 energy price cap announcement — what it means for you

The energy price cap changes again on 1 October 2026, and Ofgem announces the new level around 26 August 2026. Until then the exact figure isn’t known — here’s what the cap actually is, what the announcement will mean, and what’s worth doing now.

• What the cap is. Ofgem’s price cap limits the unit rate (pence per kWh) and the standing charge on the standard variable tariff. It resets every three months and varies a little by region. What the price cap actually is →
• What it does NOT cap. Your total bill. The cap limits the rates, not the total — use more, pay more. So the headline figure is Ofgem’s estimate for a typical home, not a limit on what you can be charged.
• The dates that matter. The current cap runs to 30 September 2026. Ofgem is expected to announce the 1 October to 31 December 2026 level around 26 August 2026. We’ll add the exact figure here as soon as Ofgem publishes it — in the meantime, the smartest move is to check whether your current rates and direct debit are fair (below).
• Why the headline can mislead. The number in the news is a yearly estimate for a typical household on typical usage. Your own bill depends on how much you actually use and your region’s exact rates — not the headline.
• What to do now. Check whether your current rates and direct debit are fair before the change lands, and weigh up whether fixing suits your home. Can you beat the next rise? → · Get ready for winter →

What the announcement will (and won’t) tell you

The 26 August announcement sets the rates from October, so it tells you which way the standard variable tariff is moving. It won’t tell you your bill — that still comes down to your usage. If the new cap is higher and a fix is at or below it, locking in can add certainty; if fixes are well above the cap, you may prefer to stay flexible. Should you fix? →

Whatever the new cap turns out to be, the useful move is the same: know your own numbers. The free bill check reads your rates off a photo of your bill and compares them to the current cap, and weighs your direct debit against your real usage — in about 30 seconds, with nothing saved.
