You’ll need to choose between fixed and variable tariffs.
A fixed tariff gives you the peace of mind. This is because the price you pay for each unit of energy, and any standing charges, won’t change for a set period.
You get protection if prices go up – but you don’t benefit in the unlikely event of prices going down.
You might also have to pay an exit fee if you want to switch suppliers before the end of your deal.
Comparison websites will want to know how much energy you use, whether in pounds spent or kilowatts (kwh) used.
If you don’t know, they can make a rough guess based on the size of your house, how many people live there, and the appliances you use.
With a variable rate tariff, your bills rise and fall based on what’s happening in the energy market. If energy prices drop so will your bill, and if they rise, you’ll need to be prepared to cover higher costs.
“Standard variable green energy tariffs” are not protected by the Ofgem price cap, only default or standard variable rate tariffs are. You can ask your supplier if you’re not sure.
