Fixed energy tariff vs variable tariffs comparison
With a fixed tariff, you pay a set unit price over the lifetime of your gas and electric contract. So, your unit price doesn't change when energy prices go up, making it cheaper than our standard prices when this happens. It helps you budget better and gives you peace of mind.
This is possible because we buy your energy in advance, meaning it isn't affected by fluctuations in electricity and gas wholesale prices.
A variable tariff means the unit cost can go up or down at any time, provided they remain no higher than Ofgem's price cap. This means your prices are not protected against what's happening in the wholesale energy market, which means you can't budget as well as you can when your prices don't change.
| Fixed rate tariff | Variable rate tariff |
| Pay the same price for your gas and electricity units for as long as your tariff terms are fixed for. | Your energy costs can increase or decrease depending on the latest energy prices and Ofgem's price cap. The price cap is reviewed every three months. |
Your contract lasts for as long as the terms you agreed to. | Your contract rolls over year after year. If you are on a fixed tariff and don't choose a new deal, you default to a variable gas and electricity rate tariff. |
Early exit fees usually apply on fixed tariffs, so it's always worth checking what these are before changing energy suppliers or choosing a cheaper deal. | No exit fee, so you can change energy suppliers or choose the cheapest energy deal whenever you want. |

How long will it take to switch my energy to EDF?
How long the process takes depends on whether you chose to switch to us after or within your 14-day cooling off period.
If you chose to switch after your cooling off period, the switching process should take place within five working days after your cooling off period ends. If you chose to switch within your cooling off period, your switch should be completed within five working days (before your cooling off period ends).
In both instances, it can take longer if any issues arise along the way. For example, if your current supplier objects to the switch. We'll keep you up to date throughout, so you always know what's going on.
