Energy price cap explained
Understand the Ofgem energy price cap. What it means for you, how often it changes, who it affects, and your options with EDF
At a glance
Ofgem (the energy regulator) has announced the latest energy price cap for 1 October to 31 December 2026.
- From 1 October 2026, Ofgem will increase the price cap by 4% until 31 December. 4% higher than the current cap
- This means from 1 October to 31 December, a typical household on a default tariff will pay £1,723 for what currently costs £1,663 a year, based on Ofgem's average(1)
But remember: The price cap limits the price you pay for energy, not your total bill. The more energy you use, the more you'll pay - Prices will change on 1 October 2026 for any EDF customer on a standard variable, deemed or tracker tariff
- Prices change quarterly in Jan/Apr/Jul/Oct

Other changes happening at the same time
From 1 October, the VAT rate on domestic electricity in Great Britain will be temporarily reduced from 5% to 0% following a UK Government decision.
The government expects that cutting the VAT paid on electricity will save people around £45 a year, although the actual saving will depend on individual electricity usage. The VAT cut will apply to all electricity tariffs, including fixed energy tariffs. Read our blog on what the VAT cut means.
Latest update on the price cap
What's happening
From 1 October 2026, Ofgem (the UK energy regulator) are increasing gas and electricity prices by 4%.
What this means for you
- Customers on variable or tracker tariffs: your prices will be automatically updated on 1 October. If you're staying on cap prices, make sure your meter readings are up to date before your prices change on 1 October
- Direct Debit payments: We'll review your Direct Debit payments and let you know if any changes are needed to keep up with the new prices. Please don’t change your Direct Debit, as changing your payment before a review could result in debt
- Prepayment customers: You'll see the new prices when you first top up after 1 October. Gas prices could update on prepayment customers' meters any time from today (after a top-up), but they won't activate until 1 October 2026
David Edmonds, Head of Portfolio Pricing at EDF Wholesale & Business Services, explains why the price cap is increasing
A 4% rise in the price cap is unwelcome for consumers, particularly ahead of winter when energy use increases.
While global gas market disruption has driven the increase, the impact has been limited by the price cap methodology and suppliers hedging energy purchases in advance.
However, wholesale markets currently point to a larger increase in Q1-27, making fixed tariffs worth considering as protection against further price rises."

What is the energy price cap?
The energy price cap was introduced in 2019, when energy prices began to spike. It is a limit set by Ofgem, the UK’s energy regulator. It sets a maximum on:
- Unit rates: The price you pay for each unit of gas and electricity you use
- Standing charges: The daily fee you pay to stay connected to the energy network
How often does it change?
The price cap is reviewed quarterly by Ofgem: January, April, July, and October. If you’re on a variable or tracker tariff, your unit rates and standing charges will adjust automatically when the new rates take effect. Fixed-price tariffs, however, remain unchanged for the duration of the contract term.
Our energy experts have created price cap predictions to help you decide whether to stay on a variable tariff that tracks the cap or switch to a fixed-price or tracker tariff, making it easier to find the best option for you.
Does the price cap apply to me?
The price cap applies if you’re on one of EDF’s variable or tracker tariffs. Here's a list of our current tariffs
- Variable tariffs: Standard Variable, Welcome, Deemed, Safeguard Assist
- Tracker tariffs: Simply Tracker, Evolve Tracker, Heat Pump Tracker, Heat Pump & Save Tracker, Heat Pump & Power Tracker, Empower, Empower Tracker Exclusive V2
Not sure which tariff you’re on?
You can check your tariff name in MyAccount or on your latest bill. Customers who use our mobile app can find this info under 'tariff details'.
Should I stay on the price cap or switch?
If you’re on one of our variable or tracker tariffs, your prices can go up or down in line with the price cap every three months. For some customers, switching to a different tariff can bring savings or peace of mind.
We encourage every household to compare all available tariffs and choose the option that offers the best protection for the year ahead.

What does the energy price cap mean for my bill?
Your prices will automatically change on 1 October in line with the price cap. This means that your next bill, after this date, will reflect any changes.
If I’m on a fixed tariff, will I be affected?
No, your rates and standing charges stay the same until your tariff plan ends. Don't forget to choose another fixed plan when your existing one ends if you want to continue benefiting from fixed rates.
How do I check which tariff I’m on?
You can check which tariff you're on by logging into your account and looking under tariff details on your home screen. Alternatively, you'll be able to see your tariff info on your latest bill (on page 2) under the 'About your tariff' section.
Does this mean I’ll only pay £1,723 a year?
No. The £1,723 annual bill value is based on Ofgem's current typical usage value, which they reference when discussing the price cap.(1)
Your bill depends on how much energy you use. Use more, pay more. Use less, pay less.
