Enjoy flexibility with Simpler Energy
Our Standard Variable tariff, Simpler Energy, is designed for those who value freedom. Unlike fixed-term contracts, this tariff has no fixed end date and zero exit fees, meaning you have the total flexibility to change your plan or switch providers whenever you choose without penalty. Your costs are made up of a unit rate for the energy you use and a daily standing charge for the maintenance of your energy supply. Because this is a variable plan, these rates fluctuate up and down in line with the Ofgem price cap.

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 bychoosing 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. You can use the predictions table above to see the general trends for an average UK household.
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.
