The UK Energy Price Cap Explained:
October 2026 Update
From 1 October to 31 December 2026, the Ofgem energy price cap is set at £1,723 per year for a typical household that uses electricity and gas and pays by Direct Debit.
That is £60, or around 4%, more than July to September, when the equivalent figure was £1,663. If you remember July’s cap as £1,862, you’re not wrong – Ofgem has changed how it describes a ‘typical’ household, which we explain below.
The bigger news is what comes next. Analysts at Cornwall Insight expect the cap to rise by around 16%, to £1,999, from January 2027.
This guide explains what these numbers mean, how the cap works and, most importantly, what you can do to manage your energy costs.

What is the Ofgem Energy Price Cap?
A Simple Definition
The energy price cap is a limit set by Ofgem, the energy regulator for Great Britain, on the maximum amount suppliers can charge you for each unit of energy and the daily standing charge. It was introduced in 2019 to protect customers on default or standard variable tariffs (SVTs) from paying excessively high prices.
A crucial point to understand is that it is not a cap on your total bill. The more energy you use, the more you will pay. Think of it like a petrol pump: the price per litre is capped, but your final cost depends on how many litres you put in your car. The headline figure of £1,723 is what a household with ‘typical consumption’ – 2,500 kWh of electricity and 9,500 kWh of gas a year – would pay over a year at the current rates.
The Latest Energy Price Cap Rates:
October to December 2026
The £1,723 figure is an average. Your actual bill will depend on your energy usage, where you live in the country, and how you pay your bill. To understand the real impact on your finances, you need to look at the specific unit rates and standing charges.
For the period of 1 October to 31 December 2026, the national average rates for a customer paying by Direct Debit are as follows:
Why Did July’s £1,862 Become £1,663?
From 1 July 2026, Ofgem changed the ‘typical domestic consumption values’ it uses to turn unit rates and standing charges into a headline annual bill. A typical household is now assumed to use 2,500 kWh of electricity and 9,500 kWh of gas a year, down from 2,700 kWh and 11,500 kWh.
Nothing about the prices changed. Ofgem first announced July’s cap as £1,862 on the old basis; on the new basis, the same rates work out at £1,663. April to June 2026 falls from £1,641 to £1,477 in the same way.
This matters when you compare figures. Headline caps from before July 2026 – including most of those in our history table below – use the old, higher usage, so they aren’t directly comparable with £1,663 or £1,723. The fairest comparison is always the unit rates and standing charges, together with your own usage.
Why Did the Energy Price Cap Change This Quarter?
The October to December 2026 price cap is around 4% higher than July to September, mainly because wholesale gas prices have stayed high amid the conflict in the Middle East.
The rise falls mostly on gas: the gas unit rate is up by around 9%, while the electricity unit rate is almost unchanged. That is partly because electricity bills carry no VAT from 1 October 2026 to 30 June 2027, under the government’s temporary VAT cut.
Wholesale energy costs make up the largest part of the cap, so movements in the global gas market have an outsized effect on what households pay.
Prices remain well below the peak of the 2022 energy crisis, when government support capped typical bills at £2,500.
How the Energy Price Cap is Calculated:
Anatomy of Your Bill
To truly understand your bill, it helps to see where your money goes. Ofgem calculates the price cap by looking at all the legitimate costs that suppliers face to get energy to your home.
The main components of your bill are:
- Wholesale Energy Costs: This is the largest single component and reflects the price suppliers pay for gas and electricity on the market.
- Network Costs: This covers the cost of transporting energy through the national grid of pipes and wires to your home.
- Policy Costs: This portion funds government initiatives, such as supporting vulnerable customers and promoting renewable energy generation.
- Operating Costs: These are the day-to-day costs suppliers incur for services like billing, customer support, and metering.
- VAT: Gas bills carry 5% VAT. Electricity carries no VAT from 1 October 2026 to 30 June 2027, under the government’s temporary cut – it is normally 5%.
The Standing Charge Explained:
The Daily Cost You Can’t Avoid
One of the most frustrating parts of any energy bill is the standing charge. This is a fixed daily fee that you have to pay, regardless of how much energy you use.
Based on the current rates, this unavoidable cost amounts to approximately £200 per year for electricity and £108 for gas.
Many energy-conscious consumers feel penalised by this charge, as it reduces the financial benefit of their energy conservation efforts.
Standing charges remain controversial. This quarter, the electricity standing charge has fallen to 54.83p a day (from 57.19p), while gas has edged up to 29.68p (from 29.04p). Most of this quarter’s increase comes through the higher gas unit rate rather than standing charges.
A History of the Price Cap:
From Crisis to a New Normal
To understand the regulator’s new prices, we need to look back at the extreme volatility of recent years. The energy crisis, which began in late 2021, saw wholesale prices reach unprecedented levels. Without government intervention, the Ofgem price cap would have soared to £4,279 in January 2023.
To prevent this, the government introduced the temporary Energy Price Guarantee (EPG), which subsidised bills and capped the typical household cost at £2,500. While the current cap of £1,723 is significantly lower than the crisis peak, it remains much higher than pre-2021 levels, reflecting a new, more expensive normal for energy costs.
Energy Price Cap Forecast:
What Will Bills Look Like in 2027?
Looking ahead, analysts expect bills to rise sharply in the new year. Cornwall Insight’s latest forecast, updated on 14 October 2026, puts the January to March 2027 cap at £1,999 for a typical household – about 16%, or £276, more than now.
The main driver is the escalating conflict in the Middle East, which has disrupted gas supplies and pushed up the wholesale prices Ofgem uses to set the cap. Ofgem is expected to confirm the January figure in late November, and we’ll update this guide when it does.
Forecasts can change quickly, but with winter bills already higher because homes use more energy, now is a good time to look at the options below.
How to Lower Your Energy Bills:
Your Options Under the Cap
While the price cap may feel out of your control, there are still actions you can take to manage your energy bills.
For the first time in several years, the energy switching market is active again. It is worth comparing fixed-rate tariffs against the current price cap, but make sure you check exit fees and the exact unit rates and standing charges before switching.
A fixed tariff locks in your unit rates and standing charge for a set period, typically 12 months, protecting you from future price cap increases.
With a rise forecast for January, it is worth comparing fixed deals now. Use a price comparison tool to see if a fixed deal could save you money, but be sure to check for any early exit fees.
The government and energy suppliers offer several support schemes for vulnerable households.
The Warm Home Discount, for example, provides a £150 rebate on electricity bills for eligible low-income households.
If you are struggling to pay your bills, the most important step is to contact your supplier immediately. They have a regulatory obligation to help you, which could include setting up a manageable repayment plan.
The most direct way to lower your bill is to use less energy.
Simple measures like improving your home’s insulation, draught-proofing doors and windows, and being mindful of appliance usage can make a significant difference.
What the Price Cap Means If You Have Solar Panels, a Battery or a Heat Pump
Switching tariffs and using less energy help you cope within the cap, but they leave you exposed to the next rise. The long-term answer is to rely less on the grid – and if you generate or store your own electricity, or heat your home with a heat pump, the price cap affects you differently.
Solar panels
Every unit of solar electricity you use yourself is a unit you don’t buy at the capped rate – currently 26.32p/kWh. When the cap rises, so does the value of your solar.
You save the most by using your solar power as it’s generated: running the dishwasher or washing machine in the daytime, or charging an electric car while the sun is out.
Electricity you export isn’t covered by the cap. You’re paid for it under a Smart Export Guarantee (SEG) tariff, which you choose separately. Export rates are usually lower than the price of grid electricity, so solar power you use at home is generally worth more than power you sell.
See what solar panels could save you with our Solar Savings Calculator.
Battery storage
Smart and time-of-use tariffs sit outside the price cap, often with cheap overnight rates and higher prices at the evening peak. A home battery can charge when electricity is cheapest and power your home through the peak, even without solar – and with solar, it stores your spare daytime energy for the evening.
Compare tariffs with our Smart Tariff Finder, then use the Battery Storage Calculator if you don’t have solar yet, or the Battery Retrofit Checker if you already do.
Heat pumps
Gas accounts for most of this quarter’s rise, and the cap doesn’t cover heating oil or LPG at all. An air source heat pump runs on electricity, which carries no VAT until 30 June 2027, and many suppliers offer heat pump tariffs with cheaper rates.
Our Heat Pump Savings Calculator shows what you could save, and our Boiler Upgrade Scheme guide explains the £7,500 grant – £9,000 for oil and LPG homes. To see how solar, a battery and a heat pump work together, try our Whole Home Energy Planner.

Frequently Asked Questions (FAQ)
No. The price cap limits the rates your supplier can charge per unit of energy and for the daily standing charge. Your total bill is not capped and will depend entirely on how much energy you use.
No, the Ofgem price cap applies only in England, Scotland, and Wales. Northern Ireland has a separate energy market regulator that sets its own price controls.
Ofgem is expected to announce the price cap for 1 January to 31 March 2027 in late November 2026. Cornwall Insight currently forecasts £1,999 a year for a typical household, up about 16%.
If you are on a fixed-rate tariff, the Ofgem price cap does not affect you. Your unit rates and standing charge are locked in for the duration of your contract. You will only be moved to a tariff subject to the price cap if your fixed term ends and you do not choose a new deal.
Ofgem changed the typical usage it bases the headline figure on, from 2,700 kWh to 2,500 kWh of electricity and from 11,500 kWh to 9,500 kWh of gas a year. The unit rates and standing charges didn’t change – only the example household did.
No. The price cap only applies to default tariffs, also called standard variable tariffs. Fixed, smart and time-of-use tariffs set their own prices, which can be higher or lower than the cap. If you have a battery or a heat pump, a time-of-use tariff can be much cheaper.
Conclusion
To summarise, the Ofgem energy price cap for a typical household is £1,723 a year from 1 October to 31 December 2026, up 4% on July to September.
Analysts expect a bigger rise in January, with Cornwall Insight forecasting £1,999, and future price cap movements remain uncertain while the conflict in the Middle East continues.
While short-term measures like switching tariffs or reducing consumption can provide some relief, the most effective long-term strategy for achieving stable and predictable energy costs is to reduce your reliance on the grid by generating your own electricity with solar panels and consuming as much of your solar energy as possible with the help of battery storage.
