Fixed energy deals have been returning to the market following the energy crisis.
These fixed tariffs can beat Ofgem’s current price cap by around £258, so it’s worth comparing energy providers to make sure you’re not paying more than you need to.
Ofgem has hiked the energy price cap for the last three quarters, so households on a variable tariff are paying even more for energy.
And although the price cap is anticipated to fall in July to around £1,683, the best priced fixes still beat this rate.
This has left many homeowners weighing up whether now’s a good time to fix energy prices.
Along with comparing energy tariffs, it’s a good idea to try cutting your bill with our energy saving tips too.
Certainty over your bills: The unit cost of energy won’t rise when you’re on a fixed tariff
The table below shows you the cheapest energy deals this week. It’s a good idea to compare the best deals with what you are currently paying, because rates vary by region.
Energy companies charge for energy by the kilowatt hour (kWh), so if you use more than the average household, you will pay more.
It is therefore important to check the unit rate – how much you are charged per kWh – on a new fixed tariff against that of your existing deal.

Should I fix my energy and switch providers?
Switching to a fixed tariff from a variable one could put more money in your pocket. It’s also worth thinking about fixing your energy if you like to know exactly how much your bills will be each month.
Energy costs and standing charges stay the same over the length of a fixed contract, helping you budget.
Jonathan Brearley, the chief executive of Ofgem, has said that customers should consider switching or fixing to try to lower costs and give certainty over payments. He’s also said that prices are set to remain high and volatile for the foreseeable future.
The latest prediction from energy consultancy Cornwall Insight has the cap falling to around £1,683 in July. Energy provider EDF is predicting that the cap will hover slightly above £1,700 over the next six months. Keep in mind these predictions are based on current prices and views and it’s impossible to know exactly what will happen, especially the further into the future they look.
The energy market is easily influenced by international events and political tensions that can’t be forecast.

How many fixed energy deals are there?
While there are now fixed-rate energy deals that households can switch to that undercut the Ofgem price cap and save money, it’s taken a few years for providers to start offering them again.
Until the energy crunch arrived in late 2021, the advice was simple: households should switch energy providers regularly to get the best deal possible.
The cheapest deals were fixed-rate tariffs, with variable rates normally reserved for households that had reached the end of their cheap tariff and not switched.
But affordable fixed-rate deals began to vanish in autumn 2021, because wholesale energy prices started rising.
Many comparison sites then paused their energy switching services, energy providers stopped taking on new customers, and the common advice was that most people would be better off on deals subject to the Ofgem price cap.
This has left 22 million households lumbered with variable-rate deals.
With fixed energy tariffs returning to the market, switching energy provider could once again help you save money on bills.
Can my energy price increase on a fixed tariff?
Your energy provider can’t raise your unit cost of energy or standing charge while you’re on a fixed tariff.
Your bill could still move up and down depending on how much energy you use. If you use more, you’ll pay more.
It’s the standing charge and cost per unit of energy that’s fixed, not your overall bill.
Is now a good time to fix energy prices?
The price cap has risen three times in a row, meaning it’s a good time to look for a fixed energy deal.
You could save money if you can find one that beats the current cap and forecasts for future changes. Be sure to consider how much the cap will move over the whole year, not just the next few months.
