How to get a cheap energy deal
Using an energy comparison tool like ours is a trusty way to get the best deal for your home as there are a few variables to consider when shopping for energy, – your home's location, layout, and your usage – so comparing energy tariffs isn't always simple. For starters, having a recent bill to hand showing how much you have used and paid in previous months is very handy.
When you buy energy you may start on a fixed term tariff. When comparing deals, compare the lengths of these tariffs as they can be between 12 and 24 months meaning the guaranteed cost you pay is set for a certain length of time. A fixed term tariff will tend to work out to be the cheapest so try not to get lured in by cheap variable tariffs that could sting you in a few months if prices rise.
What does a fixed tariff mean?
A fixed energy tariff guarantees that a unit of energy will be sold to you at the same price for the duration of the fixed term (usually a year). You'll stay pay for the energy you use, but your costs per unit will not go up.
Will I have to pay to switch energy suppliers?
That depends on the terms of your current contract – some energy providers will charge you an exit fee if you want to leave mid-contract, so take those into account if you're considering switching. Plenty offer no-exit-fee contract, though, so if you're not sure you'll want to stay with the same provider for the whole year, that's something to pay attention to. Other than that standard exit fee, it won't cost you anything to switch.
