The Energy Price Cap Rises on 1 October: Read the Rates, Not Just the £1,723 Headline

From 1 October 2026, Ofgem’s energy price cap rises by 4 per cent. The headline annual figure becomes £1,723 for a typical household paying by Direct Debit and using both gas and electricity. That number is useful for tracking the market. It is not the maximum any household can be charged.

Your real bill still depends on how much energy you use, where you live, how you pay, which tariff you have and whether the supplier is using accurate readings. The practical task is therefore not to memorise £1,723. It is to locate the rates that apply to your home and make sure the first bill under them is based on the right consumption.

What changes on 1 October

Ofgem announced on 26 August that the cap for 1 October to 31 December 2026 would rise by £60 a year—about £5 a month—for a typical dual-fuel Direct Debit household if the quarterly rates lasted for a full year. The regulator says higher wholesale gas prices are the principal reason for the increase. Read the Ofgem announcement.

For an average Direct Debit customer across England, Scotland and Wales, Ofgem publishes these rounded benchmark rates:

Charge	1 July–30 September 2026	1 October–31 December 2026
Electricity unit rate	26.11p per kWh	26.32p per kWh
Electricity standing charge	57.19p per day	54.83p per day
Gas unit rate	7.33p per kWh	7.97p per kWh
Gas standing charge	29.04p per day	29.68p per day

The detailed regional tables are available on Ofgem’s unit-rate and standing-charge page. Use your postcode region and payment method rather than assuming the national average is your tariff.

The cap limits rates, not the final bill

The cap applies to the maximum unit rates and standing charges suppliers can set on protected default tariffs. It does not create an “all you can use” annual bill. A home using more than the typical consumption assumption can pay more than £1,723; one using less can pay less.

A simplified bill check is:

Energy used × unit rate, plus daily standing charge × number of days, plus or minus account adjustments.

Real bills may also show credit carried forward, debt repayment, estimated readings, discounts or corrections. Direct Debit is a payment arrangement, not a measurement of that month’s consumption: suppliers often smooth expected annual costs across twelve payments.

Who is affected—and who may not be

• Default or standard-variable tariff: the cap normally applies, and the October rates matter.
• Fixed tariff: the contracted unit rates generally continue until the fix ends, although the electricity VAT change is applied by suppliers. Ofgem estimated in August that about 11 million households were on fixed tariffs.
• Economy 7 or another multi-rate tariff: day and night rates differ; their combined treatment must comply with the cap, but the national single-rate figure is not your precise price.
• Prepayment or standard credit: use the appropriate Ofgem table because the capped rates differ by payment method.
• Northern Ireland: Ofgem’s Great Britain price cap does not govern the separate Northern Irish energy market.

Check the tariff name and end date on your bill or online account before acting. A news headline cannot tell you whether you are fixed, variable, single-rate, multi-rate, prepayment or standard credit.

Why older headline comparisons are unusually tricky

Two presentational changes complicate comparisons. First, the government removed VAT from domestic electricity bills from 1 October 2026 to 31 March 2027. Gas continues to include 5 per cent VAT. The electricity VAT reduction is already reflected in the October cap figures and should be applied automatically, including to eligible fixed-tariff customers. The government said the temporary cut was intended to provide cost-of-living relief; see its September announcement.

Second, Ofgem updated its Typical Domestic Consumption Values in July because average household use has fallen. Under the new benchmark, the representative annual figure moves from £1,663 to £1,723. Ofgem says that if the old 2023 consumption benchmark were retained, the comparable figures would be £1,862 and £1,935. This does not mean the cap secretly fell or rose by a different amount: it means the illustrative household changed.

The evidence is the published rates and methodology. The interpretation is that consumers should be cautious when comparing today’s annual headline with an older one. Any prediction about an individual winter bill remains speculation until that household’s tariff and consumption are known.

Gas drives most of this increase

Ofgem says the gas portion of a typical bill rises by about 8 per cent, while households without gas should see an increase of less than 1 per cent. The VAT removal keeps typical electricity costs broadly stable even though underlying market costs have increased.

This distinction matters for household planning. An all-electric flat, a gas-heated family house and a home using a heat pump can respond differently to the same national headline. Compare fuel-specific unit rates and your own previous kilowatt-hours, not only pounds paid.

Take and keep a boundary meter reading

If you do not have a communicating smart meter, take clear electricity and gas readings close to the rate-change date and submit them through your supplier’s official channel. Photograph the meter with the figures visible and retain the submission confirmation. This creates a boundary between energy used before and after the new rates.

You do not need to create a rush at exactly midnight. Follow your supplier’s submission window and do not use links from unsolicited texts. Citizens Advice recommends regular readings when estimated bills appear too high; an accurate reading allows the supplier to issue a corrected bill. See its guidance on checking a high energy bill.

Run a seven-line October bill check

1. Tariff: Is it fixed, default variable, single-rate or multi-rate?
2. Region and payment method: Are you comparing the correct Ofgem table?
3. Meter status: Is the reading actual, smart, customer-supplied or estimated?
4. Unit rates: Do electricity and gas match the supplier’s notified rates?
5. Standing charges: Have they been multiplied by the correct number of days?
6. VAT: Is zero VAT applied to domestic electricity while gas retains 5 per cent during the temporary period?
7. Direct Debit: If it changed sharply, has the supplier explained the forecast usage, balance and calculation?

Citizens Advice recommends submitting readings and asking the supplier to explain a Direct Debit increase. A higher payment may reflect the new cap, a debit balance, changed usage estimates or several factors together. Do not assume the entire difference is the 4 per cent cap movement.

Check a fixed deal as a complete contract

Ofgem noted in August that some fixed tariffs were available below the October cap. That does not make every fix suitable. Compare unit rates, standing charges, length, exit fees, payment method, smart-meter requirements and whether a cheaper time-of-use rate fits your routine.

A fix transfers some future price uncertainty to the supplier; it does not guarantee the lowest eventual cost. The October cap lasts only three months and the next capped rates may move up or down. Treat claims about the “best” future tariff as forecasts, not facts.

If the bill is unaffordable, contact the supplier early

Ofgem says customers struggling to pay should contact their supplier as soon as possible. Suppliers should discuss affordable repayment plans and routes to financial assistance. Its energy-bill support page also explains help including supplier grants, benefit-linked debt repayment and independent advice.

Tell the supplier about disability, serious illness, young children, communication needs or reliance on powered medical equipment where relevant, and ask about the Priority Services Register. Keep notes of calls, dates, promised actions and complaint references.

The useful takeaway

The October news is real: the representative cap rises 4 per cent to £1,723, with gas accounting for most of the increase. But the household decision lives below the headline. Identify the tariff, record the meter, check the actual rates and challenge unexplained estimates or payment changes.

The cap can limit the price of each unit. Only accurate consumption data, a suitable tariff and early support can turn that protection into a manageable bill.
