Energy price cap: October 2026

October 2026: what's changing for your bill

Ofgem confirmed the new cap on Wednesday 26 August 2026. Here is what was announced, and what it actually does to a bill:

The important detail is where the rise came from. It is almost entirely gas: gas bills rose about 8%, while electricity stayed broadly flat because the VAT cut absorbed the wholesale increase. So the £60 is not spread evenly across your bill — a household that heats with gas feels most of it, and a household on electric heating or a heat pump feels comparatively little.

Two things the headline does not tell you. First, the cap limits prices, not your total bill: use more than the typical household and you will pay more than £1,723, use less and you will pay less. Second, about 35% of households — roughly 11 million — are on fixed tariffs and are not affected by this change at all. Prepayment customers pay the lowest capped rates, around £45 a year less than Direct Debit.

Two traps when comparing headlines. Ofgem itself warns that October's costs "cannot be compared directly to previous periods" because the electricity rate is now quoted excluding VAT while earlier periods included it — so a straight rate-to-rate comparison overstates the fall in electricity. And separately, on 1 July 2026 Ofgem cut its "typical household" consumption assumptions — now 2,500 kWh of electricity and 9,500 kWh of gas a year, about 7% less electricity and 17% less gas than before — so figures quoted on the new basis are not comparable with those you saw last winter either. Those two numbers are what the £1,723 is built from: use noticeably more than that and the headline understates your bill. If you see October 2026 quoted at anything near £1,900, it is being stated on the old consumption basis.

What the cap limits, and what it does not

The Ofgem price cap is a cap on the maximum unit rate a supplier can charge for each kilowatt-hour (kWh) of gas and electricity, plus a cap on the daily standing charge — the fixed amount you pay every day regardless of usage. It is not a cap on the total bill. The widely-quoted headline figure (for 1 July to 30 September 2026, £1,663 a year on Ofgem's new typical-use basis) is simply what those capped rates would add up to for a household with typical consumption paying by Direct Debit. On 26 August 2026 Ofgem confirmed the October to December level at £1,723. Use more energy than the typical household and you will pay more than the headline; use less and you will pay less. Nobody's bill is "capped at £1,663".

The cap is set by Ofgem and reviewed every three months, taking effect on 1 January, 1 April, 1 July and 1 October. It applies to default and standard variable tariffs in England, Scotland and Wales — not to Northern Ireland, which has a separate regime, and not to fixed deals you have actively chosen. Each region of Great Britain has slightly different capped rates because the cost of moving energy around the network varies. Payment method also matters: paying by Direct Debit is usually capped lower than paying on receipt of a quarterly bill, while traditional prepayment meters sit on their own capped level.

The standing-charge debate

Standing charges have become the most contested part of the cap. Because they are charged per day before you use a single unit, a household that uses very little energy can find the standing charge is a large share of its bill — which feels unfair to people who have worked hard to cut their usage. Following a long consultation, Ofgem has been moving towards giving customers a choice of a low or zero standing charge tariff (with a correspondingly higher unit rate) alongside the standard structure. The trade-off is real: a zero standing charge suits very-low-use homes, but if you use an average or above-average amount of energy, a higher unit rate can cost you more overall. Always compare the standing charge and the unit rate together, not one in isolation.

Fixed versus variable tariffs — and when fixing wins

A variable (default) tariff moves with the cap: when Ofgem lowers the cap your rates fall, and when it raises the cap they rise. A fixed tariff locks your unit rates and standing charge for a set term, usually 12 to 24 months, regardless of what the cap does. Fixing is essentially buying certainty. It wins when fixed deals are priced at or below the current cap and you expect the cap to rise, or simply when a predictable bill matters more to you than chasing the lowest possible price.

Before fixing, check two things. First, the exit fees: many fixes charge a penalty (often per fuel) if you leave early, so a fix only makes sense if you intend to see out most of the term. Second, how the fixed rate compares to the current cap rather than to the scary headlines from a previous quarter. A deal that looked good against last winter's cap may be poor value against today's. If you cannot find a fix priced below the cap, staying on the capped variable tariff is a perfectly reasonable default — the cap is a backstop, not a penalty.

Help schemes if money is tight

Several government and supplier schemes can reduce what you pay or add a one-off credit. The amounts and exact eligibility change from year to year, so always check the current rules on GOV.UK or with your supplier, but the mechanisms are stable:

• Warm Home Discount — a one-off rebate applied to the electricity account of eligible households over winter. For most people it is applied automatically if you receive a qualifying benefit and your supplier takes part; you usually do not need to repay it.
• Winter Fuel Payment — an annual payment to help people over State Pension age with heating costs, paid automatically to most who qualify. Eligibility rules have been tightened in recent years, so check whether you still qualify.
• Cold Weather Payment — paid to certain benefit recipients when the local temperature is recorded at or forecast to be at or below zero for seven consecutive days. It is automatic in England and Wales; Scotland runs its own Winter Heating Payment instead.
• Household Support Fund — money distributed through local councils to help with essentials including energy. Because each council sets its own scheme, you apply (or are referred) through your local authority rather than your supplier.

Suppliers also run their own hardship and trust funds, and some offer grants towards arrears. It is always worth asking your supplier directly what support they offer.

What to do if you cannot pay your energy bill

If you are struggling, contact your supplier early — under Ofgem rules they must work with you to agree affordable repayment. By licence condition, a supplier has to offer customers in difficulty options such as a realistic payment plan based on what you can afford, a review of your Direct Debit, payment breaks in some cases, and access to hardship support. The worst thing you can do is ignore letters; engaging keeps you in control of the plan.

Two protections are worth knowing. The Priority Services Register is a free service every supplier and network operator must offer to people in vulnerable circumstances — for example pensioners, disabled customers, those with long-term health conditions, or households with young children. Registering can get you advance notice of planned power cuts, priority support in an outage, accessible-format bills, and extra help if you are on a prepayment meter. Separately, suppliers must follow strict rules before disconnecting anyone, and there are seasonal protections: they should not knowingly disconnect a household with children under a certain age or with people of pension age over the winter months. Forced installation of a prepayment meter to recover debt is also tightly restricted and should never be used against the most vulnerable customers.

Cutting usage and the role of smart meters

Because the bill is driven by the kWh you actually use, the most reliable saving is using less. A smart meter does not save energy by itself, but by showing near-real-time consumption on an in-home display it helps you see which habits and appliances cost the most, and it sends accurate readings so you are billed on real use rather than estimates. That accuracy also unlocks time-of-use tariffs, where electricity is cheaper at off-peak times — useful if you can shift heavy loads such as laundry, dishwashers or EV charging to those windows.

Low-cost steps still do most of the work: turning the thermostat down by one degree, draught-proofing, using heating controls and timers, washing at lower temperatures, and not leaving high-draw appliances on standby. If you own your home, the bigger wins are insulation and an efficient heating system, and you may be eligible for help through government efficiency schemes — the Energy Saving Trust is a good independent starting point for what is worth doing in your property.
