I want to know where I stand and budget my energy spend
If sticking to a budget is your thing and you don’t like surprises, then consider a fixed energy tariff. Fixed rate energy deals fix the amount you pay per kilowatt hour (kWh) of energy (this is how your energy usage is calculated) and are often cheaper than other deals. You can also get online fixed rate deals too if that’s still important to you.
The advantage of having a fixed rate is that whilst your bill will vary based on how much energy you use, the actual amount you pay per kWh, won’t. It’ll give you certainty as your energy bill should remain fairly static if your energy consumption is steady so it means your bills won’t suddenly skyrocket. But the disadvantage is that you won’t benefit from any reductions in wholesale energy costs that you might on a variable tariff.
Fixed tariffs (as their name suggests) are set for a period of time, if you decide you want to change suppliers then you might be charged an exit fee if you leave your current energy contract early. Don’t let that put you off though as Which.co.uk has found that most suppliers charge £25-£30 per fuel.
