Ofgem announced on 26 August 2026 that the energy price cap for 1 October to 31 December 2026 will be £1,723 a year for a typical dual-fuel household paying by direct debit. That is up from £1,663 for July to September, a rise of £60 a year, roughly £5 a month, or 4%.
The catch is that £1,723 is not a bill. No household receives one for that amount. The cap limits the price of each unit of energy and the daily standing charge; the annual figure is Ofgem’s illustration of what typical use costs at those prices. The rise also lands unevenly. Gas is up about 8%, electricity is broadly flat because the Government has removed VAT from electricity bills, and the £5 a month headline hides a larger increase for homes that heat and cook with gas.
What does the energy price cap actually cap?
The cap does not cap what a household spends. It caps the price a supplier can charge per kilowatt hour (kWh) of gas and electricity, and the daily standing charge paid regardless of use. Use more units and the bill rises; use fewer and it falls. There is no ceiling on the total.
The £1,723 figure is an illustration. Ofgem applies the capped rates to the energy a typical household uses in a year. A one-person flat with electric heating sits well under it; a large, draughty, gas-heated family home sits well over it. Neither is being overcharged; they are simply not typical.
Direct debit customers also rarely see a change straight away. The monthly amount is set on estimated annual use, so a rise can take a month or two to show. Regular meter readings, or a smart meter sending them automatically, stop estimated bills drifting away from real use.
| Period | Typical dual-fuel direct debit household | Change |
|---|---|---|
| 1 July to 30 September 2026 | £1,663 a year | |
| 1 October to 31 December 2026 | £1,723 a year | +£60 a year (about £5 a month), +4% |
| Gas element | Up about 8% | |
| Electricity element | Broadly flat (VAT removed) | |
| Households without gas | Rise of under 1% |

Why did gas and electricity move differently this time?
On the gas side, Ofgem said wholesale gas prices rose 11% over the three months used to set the cap, citing conflict in the Middle East for volatile global gas markets. Neil Kenward, Ofgem’s Director General for Markets, said high international gas prices are continuing to drive energy costs in the UK. The gas element of the cap rises about 8% as a result.
On the electricity side, the Government has removed VAT from electricity bills. Ofgem said this stops bills being roughly £45 a year higher than they would otherwise have been, which is why the electricity element is described as broadly stable and why a household with no gas supply sees a rise of less than 1%. The 4% headline is an average of a fuel that went up meaningfully and a fuel that barely moved.
What does the £5 a month headline hide for gas-heavy homes?
An all-electric home is close to the under 1% end. A home that uses more gas than typical, which usually means an older property, poor insulation, a gas boiler and a gas hob, will see more than the 4% headline, because gas is the part that rose. The more of a household’s spend that goes on gas, the closer its own increase moves towards 8%. Timing compounds this: October to December is the start of the heating season, when the most gas is burned.
Who is affected by the October cap and who is not?
The cap applies to default tariffs, the ones customers land on when a fixed deal expires or when they have never switched.
| Tariff type | Households (Ofgem, 26 August 2026) | Affected by the October rise? |
|---|---|---|
| Default tariffs protected by the cap | About 22 million | Yes |
| Of which, standard variable tariffs | Around 20 million | Yes |
| Fixed tariffs | About 11 million (35%) | No, price fixed for the term |
Is a fixed tariff worth taking when fixes sit £100 under the cap?
Kenward said fixed tariffs are available at “£100 or more below the October price cap”. That sounds like an easy decision, and for many households it may be, but the mechanics matter.
A fix locks in unit rates and standing charges for the length of the deal. The cap is reviewed every quarter: the next period starts on 1 January 2027 and Ofgem is due to announce it in November. Nobody knows that figure yet. A fix £100 below the October cap is a saving today; whether it stays one depends on where the January cap lands, and the ones after that.
Here is the counterweight. Wholesale gas rose on geopolitical volatility, and volatility cuts both ways. If gas falls back, the cap follows it down within a quarter or two, and a household that fixed would be paying a price that then looks expensive. Ofgem also notes that prices are 52% below the 2022 crisis peak of about £2,500. A 4% rise is a real cost, but it is not a return to crisis, and treating it as one can push people into a long fix out of fear rather than arithmetic. The sensible comparison is the fix against what the cap might do over the whole term, including any exit fee, not against the October figure alone.

What can a household do if the direct debit is already behind?
Energy debt builds quietly. The direct debit is set on an estimate, actual use runs higher over a cold spell, and the account slips into arrears without a single missed payment. Then a cap rise arrives on top.
Ofgem’s advice to anyone struggling to pay is to contact the supplier straight away, arrange an affordable repayment plan, and ask what financial support is available. Suppliers can spread arrears over a longer period and review whether the monthly amount matches use. A fresh meter reading first means the plan rests on real numbers, not an estimate.
Energy is one line in a budget that also has to cover rent or mortgage, council tax, insurance and any borrowing. Anyone weighing an energy shortfall against those commitments may find it useful to see how the main parts of UK household finance fit together before deciding which to tackle first.
Frequently asked questions
Does the £1,723 cap mean a household’s bill cannot go above that?
No. The cap limits unit rates and standing charges, not the total. A household using more than Ofgem’s typical amount pays more than £1,723; one using less pays less.
Why is the gas part of the bill rising more than the electricity part?
Wholesale gas rose 11% over three months, lifting the gas element by about 8%. Electricity stayed broadly flat only because the Government removed VAT from electricity bills, worth roughly £45 a year according to Ofgem.
Is a household on a fixed tariff affected by the October rise?
Not while the fix lasts. Ofgem puts about 11 million households, 35% of the total, on fixed deals. When a fix ends, the household moves to a default tariff and the cap applies.
When will the next energy price cap be announced?
The cap is reviewed quarterly. The next period starts on 1 January 2027, and Ofgem is due to announce the figure in November.
The useful thing to take from 26 August is not the number but what it measures. £1,723 is a price list applied to an imaginary household. The real question for any home is how far its own gas use sits from typical, because that decides whether the true rise is closer to 1% or to 8%.…
