How to save money on energy

The energy crisis means there are currently limited deals offering a cheaper price than the Standard Variable Tariff rate set by the Ofgem’s Energy Price Cap.

Energy companies have started to offer fixed deals again, but most don’t offer good long-term value.

Some of the ways to substantially bring down your bills are improving the energy efficiency of your home, or reducing the amount of power you use.

Another way is to **switch providers with Nous.** Most households can save more than £120 without committing to a fixed deal.

A large proportion of your energy bill comes from heating your home and hot water. For the most up-to-date practical advice, read our guide to Saving money on energy.

What kind of tariff am I on?

You should be able to find out what tariff you’re on by looking at a recent energy bill. There are two main types of energy tariff: variable or fixed.

Variable tariff

Most people are currently on a standard variable tariff, which is also known as a default tariff. This means that as the cost of energy changes, your rate changes, too. At the moment, both the unit cost of energy and the level of standing charges (the cost of being connected to the energy network) are set by Ofgem’s energy price cap. This means your energy costs will change every three months when the price cap is reviewed. If the price cap falls, you’ll benefit from lower energy rates. But if the price cap rises, you’ll find yourself paying more. With a variable tariff, you can switch supplier at any time as you’re not locked into a contract.
