This guide is for general information, not financial advice. Energy prices and offers change regularly, so always check current terms with the supplier before switching.
The Ofgem price cap is the baseline that shapes what most UK households pay on standard energy tariffs. It is also the reason two suppliers can look "basically the same price" on paper yet feel very different to live with. Crucially, Ofgem has now confirmed a 13% rise from 1 July 2026, so this guide explains what the cap limits, the new July rates, and what they mean for your bills.

Ofgem price cap July 2026: a confirmed 13% rise
On Wednesday 27 May 2026, Ofgem confirmed that the Ofgem price cap will rise by 13% for the period covering 1 July to 30 September 2026. Consequently, households on standard variable tariffs face a noticeably higher bill from 1 July. On Ofgem's existing typical-use basis, the headline figure climbs to £1,862 a year for a dual-fuel household paying by direct debit, up from the current £1,641.
However, there is an important twist this quarter. Alongside the announcement, Ofgem also refreshed its Typical Domestic Consumption Values, because households now use roughly 7% less electricity and 17% less gas than at the last review. As a result, Ofgem's new official headline figure is £1,663 a year on the updated basis. In short, £1,862 is the like-for-like comparison with the old measure, while £1,663 reflects the lower-usage assumptions. Either way, the unit rates below are what actually appear on your bill.
Tim Jarvis, Ofgem's Chief Executive, said: "Today's price change reflects continued volatility in global energy markets. This means higher wholesale gas prices, driven by ongoing conflict in the Middle East, is impacting the price we pay for energy."
July 2026 unit rates and standing charges (direct debit average)
| 1 April to 30 June 2026 (previous) | 1 July to 30 September 2026 (new) | |
|---|---|---|
| Electricity | 24.67p per kWh 57.21p daily standing charge |
26.11p per kWh 57.19p daily standing charge |
| Gas | 5.74p per kWh 29.09p daily standing charge |
7.33p per kWh 29.04p daily standing charge |
Figures are national averages across England, Scotland and Wales, include 5% VAT, and are rounded to two decimal places. Your exact rates still depend on your region and meter type.
Why gas is rising far more than electricity
Notably, the rise is not split evenly. Gas bills are going up by around 24%, whereas electricity bills rise by only about 5%. This reflects the growing share of renewables on the system and a reduced reliance on gas to generate our electricity. As a result, how you heat your home matters more than ever for your total bill.
Meanwhile, around 40% of accounts (roughly 22 million) sit on fixed tariffs, so they are not affected by this increase. If you fixed earlier in the year, you can relax for now. For everyone else, the change lands automatically from 1 July.
Standard credit and prepayment
The cap level also varies by payment method. Standard credit customers (those who pay on receipt of a bill) face a higher cap, rising to about £2,005 a year, because suppliers carry more cost when bills are not paid by direct debit. Prepayment and regional rates differ too, so check Ofgem's regional tables for your precise figures.
Still on a variable tariff? Your options
If you are still on a standard variable tariff, this rise hits you from 1 July. Fixing locks your rate in for 12 months and shields you from further quarterly swings, so it is worth comparing deals now. Octopus Energy, for example, is currently offering new customers £50 of credit when they switch.
Switch to Octopus (£50 credit)Fixing is not always cheaper. If the cap later falls, a fixed deal could cost more than the variable rate, and some fixes carry exit fees. Compare the total annual cost, including both gas and electricity, before you commit.

What the Ofgem price cap actually limits
The cap applies to customers on standard variable (default) tariffs. It limits two things: the unit rate (price per kWh) and the standing charge (daily fixed fee). That is it.
It does not cap your total bill. If you use more energy than a "typical" household, your bill goes above the headline figure. Use less, and it comes down. The cap is a per-unit ceiling, not a household spending limit.
It also does not apply to fixed-rate tariffs, time-of-use tariffs, or dynamic pricing deals. Those are priced independently, which is why "below the cap" deals can exist alongside the regulated default.
How Ofgem calculates the cap
The Ofgem price cap is not guessed or negotiated. Instead, it is calculated using a published methodology and updated every three months (January, April, July, October) based on observed forward wholesale energy prices and predefined cost allowances.
The calculation includes several components:
- Wholesale energy costs make up the largest share. These are based on forward market prices for gas and electricity during the assessment period.
- Network costs cover what suppliers pay to use the national grid and local distribution networks.
- Operating costs include billing systems, customer service, and IT infrastructure.
- Policy costs fund government schemes such as renewables support and social programmes. From April 2026, the government moved certain green levies (including the ECO scheme) to general taxation, which contributed to the earlier Q2 cap reduction.
- VAT at 5% is applied to domestic energy bills.
Ofgem publishes the full breakdown and regional rate tables on its price cap explained page each quarter. Suppliers cannot legally exceed the capped rates for default tariff customers.
Why prices vary by region
Energy distribution costs differ depending on where you live. As a result, both standing charges and unit rates vary slightly by region. The headline "typical bill" is always a national average, so your exact rates depend on your distribution area (for example, North West, London, or South Wales).
If you want your precise regional rates, check your latest energy statement or use Ofgem's quarterly Annex 9 data tables.
Direct debit vs prepayment vs standard credit
The cap level also differs depending on how you pay. Direct debit is typically the lowest capped rate, because it gives suppliers predictable cash flow. Standard credit (pay on receipt of bill) is slightly higher. Prepayment meters have a separate cap structure.
When comparing suppliers, always make sure you are comparing the same payment method, otherwise the numbers are misleading.
What's coming next: the Q4 2026 price cap
With the July cap now confirmed, attention turns to the next quarter. Ofgem will announce the Q4 2026 cap, covering 1 October to 31 December, by 26 August 2026. Wholesale prices have risen by around 28% over the past three months, so the direction of travel will depend heavily on whether tensions in the Middle East ease.
For context, analysts had forecast the July cap at roughly £1,937 to £1,972 before the announcement, yet the confirmed like-for-like figure of £1,862 actually came in below those estimates. This is a useful reminder that forecasts shift with wholesale markets, so treat any pre-announcement number as an estimate rather than a certainty.
Does the cap guarantee the cheapest deal?
No. It guarantees a maximum price for default tariffs, but it does not mean you are on the cheapest available option. Suppliers can still offer fixed tariffs priced below the cap, time-of-use tariffs (such as EV-specific rates), and dynamic tariffs that track wholesale markets in real time.
This is why switching can still save money even when the cap is in place. Ofgem has said that in 2025, households on fixed deals paid around £115 less than the price cap on average (Ofgem price-cap announcement, 25 February 2026). More recently, following the July 2026 increase, comparison site Uswitch found the cheapest fixed deal undercut the new cap by up to £248 a year for a typical household (Uswitch, May 2026). Savings vary by usage and region, and the cheapest deals change often, so always check a current comparison before switching.
How smart meters interact with the cap
Having a smart meter does not change the cap itself, but it does unlock a wider range of tariff structures. The cap still applies to default smart tariffs, but smart export tariffs (for solar panels) and dynamic tariffs like Octopus Tracker or Agile are structured differently and sit outside the standard default pricing.
If you are interested in how tracker tariffs work alongside the cap, our Octopus tracker tariff explained guide covers the detail.
How exit fees work under the cap
Default (capped) tariffs typically do not have exit fees, so you can leave at any time without penalty. However, fixed tariffs may include exit fees if you leave before the contract ends. Always check your tariff terms before switching, and factor any exit fee into your comparison so you are weighing net savings rather than headline rates.
Should you fix when the cap falls?
When the cap drops, fixed deals can look less attractive, because you are paying a premium for certainty you might not need. When the cap rises, as it has from July 2026, fixing can instead lock you in below the likely variable rate.
Ultimately, the decision depends on your risk tolerance, current wholesale price trends, and whether a fixed deal sits meaningfully below where the cap is heading. There is no universal right answer. The cap is a benchmark, not a strategy.
How this affects Octopus, British Gas and E.ON Next
On default tariffs, the large suppliers tend to price at or very close to the capped rates. Differences usually appear in app quality, billing transparency, availability of smart tariffs, switching bonuses, and customer service experience.

Common misconceptions about the Ofgem price cap
- "My bill can't go above the cap." False. The cap is per unit, not per household, so higher usage means a higher bill.
- "All suppliers charge the same." On default tariffs they are very similar, but not identical. Fixed deals, smart tariffs, and switching bonuses create genuine differences.
- "Switching doesn't matter under a cap." It can still matter for service quality, switching incentives, and access to tariffs priced below the cap.
- "Standing charges are optional." They apply regardless of how much energy you use on most tariffs.
Does the cap apply in Northern Ireland?
No. The Ofgem price cap applies in Great Britain only (England, Scotland, and Wales). Northern Ireland has a separate electricity and gas market structure with its own regulatory arrangements.
FAQs
What is the Ofgem price cap for July 2026?
From 1 July to 30 September 2026, the Ofgem price cap rises by 13%. On the existing typical-use basis it equals £1,862 a year for a dual-fuel household paying by direct debit, up from £1,641. On Ofgem's updated lower-usage assumptions, the official headline figure is £1,663 a year. The new direct-debit unit rates are 26.11p per kWh for electricity and 7.33p per kWh for gas.
Why has the energy price cap gone up in July 2026?
The increase is driven by higher wholesale gas prices, which Ofgem links to the ongoing conflict in the Middle East. Interestingly, the rise is uneven: gas is up around 24%, while electricity is up only about 5%. Around 22 million accounts on fixed tariffs are unaffected. Prices nonetheless remain well below the 2022 crisis peak, when the government capped typical bills at £2,500.
Does the price cap limit my total energy bill?
No. The cap limits the unit rate and standing charge that suppliers can apply to default tariffs. Your total bill therefore depends on how much energy you use. If you use more than Ofgem's "typical" household, your annual bill will be higher than the headline figure.
Should I switch to a fixed tariff now?
It depends on the specific deal. With the cap confirmed to rise 13% from July, a competitive fix can lock in your rate for 12 months and remove exposure to further quarterly increases. However, always compare total costs, including any exit fees, and check the fix covers both gas and electricity. Fixing buys certainty rather than a guaranteed saving, so weigh it against your own usage and risk tolerance.
Why are standing charges so high?
Standing charges cover the cost of maintaining the energy grid, network upgrades (including investment in the transmission system for net zero), smart metering, and legacy costs from supplier failures in 2021 to 2022. They apply regardless of how much energy you use. There is ongoing pressure to reform standing charges, yet no major overhaul has been implemented yet.
