Energy price cap
Ofgem’s energy price cap limits what you pay for gas or electricity on a variable-rate tariff. Find out how it works – and how it affects your prices.
Important: on 1 July, we updated the figures below based on the new Typical Domestic Consumption Values figures released by Ofgem.
The price cap changed in July 2026
Ofgem announced that the new price cap is £1,663 for a typical household1 from 1 July until 30 September 2026.
All about the price cap: the cap is set by Ofgem, the energy regulator. It affects the way energy suppliers can price their energy tariffs. The cap puts a limit on how much customers on variable tariffs pay for each unit of gas and electricity. It also sets a maximum standing charge – this is used to cover the cost of things like maintenance of pipes and meters.
What this means if you pay monthly
If you're on a variable-rate tariff: Most customers on a variable tariff saw their annual costs go up on 1 July, in line with the new price cap. If your prices went up, we’ll have written to you to let you know. Remember: your actual bills still depend on how much energy your home uses.
If you're on a fixed-rate tariff: The price cap doesn’t affect prices for fixed-rate tariffs. If you’re on a fixed-rate tariff, your prices won’t change until your current tariff ends.
What this means if you're on Pay As You Go
All Pay As You Go prices are variable – which means most customers' annual costs went up in line with the price cap.
From 1 July, the cap for a typical Pay As You Go home2 is £1,620 – that’s an increase of £215 over a year.
If you have a smart meter your prices will have updated automatically on 1 July
If you have a traditional meter your prices will update when you top up from 1 July
We’ll have written to you to let you know how this affects you if your prices are going up. Remember: your actual bills still depend on how much energy your home uses.
If your home uses more energy, your costs can change
The price cap doesn’t put a limit on the total cost of your energy. Instead, it limits the amount you pay per unit of gas or unit of electricity – and for your daily standing charge. It can be helpful to think of it like filling up a car with petrol. The price per litre stays the same, but the total cost changes – depending on how much you fill up.
Energy price cap predictions
Understanding how energy prices are changing can help you stay in control of your bills.
The energy price cap changes every 3 months, which means prices on a standard variable tariff can go up or down each quarter. You can use our 5-quarter forecast below to see how future price cap changes might affect your home energy costs.
Our price cap predictions*
Here are our estimated annual costs for an average dual-fuel household on a standard variable tariff, paying by Direct Debit. Costs include VAT at today's rates (5% for gas and electricity). These predictions should only be used as a guide. Your actual bills will be based on how much energy your home uses.

You might save by moving to a fixed tariff
With a fixed tariff, your unit rates and daily standing charges stay the same for the length of your contract. This means your prices won’t change, even if the price cap does.

Important to know
*How we make our price cap predictions
There are a number of key factors that make up domestic energy tariffs and that impact our price cap predictions. These include:
Wholesale gas and electricity markets, which can be impacted by weather and geopolitical events
The cost of managing and maintaining the UK’s gas and electricity networks
Our predictions include our judgments about possible future policy changes, formulated using publicly available data. These are predictions, not guarantees, and they’ll change as market conditions and industry regulations evolve. OVO isn’t responsible for any variances or errors in long-term forecasting accuracy.
Predicted costs are based on average electricity and gas unit prices and standing charges for a customer on Direct Debit using Ofgem’s standard Typical Domestic Consumption Values (2,500 kWh for single rate electricity and 9,500 kWh for gas). Costs include 5% VAT. Find out more on Ofgem’s website.
