Why should I compare energy prices and switch? 

Comparing energy prices is the fastest way to make sure you’re not overpaying for your energy - and if you haven’t switched tariff recently, you probably are. That’s partly because households that haven’t switched within the last year are more likely to be on standard variable tariffs (SVTs), which tend to be more expensive. They’re the default tariff you’re automatically moved to once your fixed tariff ends.

It’s also partly because the energy market is competitive, and it pays to shop around. Our research shows you could save over £400 per year by switching supplier, and it isn’t just us: government regulator Ofgem has also found that comparing gas and electricity prices, and switching supplier or tariff, can make a big difference to your gas and electricity bills. 

Switching supplier can also help you get better customer service, and if you’re interested in making your home greener, then the best energy comparison sites can help you there, too. As well as finding the cheapest tariffs in your area in just minutes, they’ll let you filter your results to show green suppliers - so you can instantly see the best green energy deals in your area. 

Bear in mind that energy prices differ across the country and depending on usage - so there isn’t one cheap supplier - or one perfect deal - that will suit everyone. Potential savings are different from household to household, which means that the only way to find the best energy deal for your home is to run an energy comparison. 

What paperwork do I need for an energy comparison? 

We’ll need your postcode and address to be able to run an energy comparison, because there are 14 different energy regions, and gas and electricity prices differ in each. For the most accurate results, you’ll need a recent energy bill to hand: we need to know your current energy use, and how you pay - monthly direct debit, quarterly cash or cheque, and so on - to best calculate your potential savings.

If you don’t know how much energy you use, you can tell us how much you spend on energy instead. And if you don’t know that, we can still run an energy comparison. We’ll ask you a few questions about your home, such as whether you tend to use the most gas and electricity in the evenings and weekends or throughout the day. 

Finally, if you decide to switch, you’ll need to provide contact and payment details. This will enable your new provider to take over your energy account.

Can I compare gas and electricity prices separately? 

Of course. If you don’t want to compare duel fuel prices, just tell our energy comparison service whether you want to compare electricity only, or gas only. There are lots of single-fuel tariffs and we’ll show you the best in your area.

What’s the difference between a fixed rate, variable and standard variable tariff? 

Once you’ve run an energy comparison, you’ll see a mixture of fixed and variable tariffs in your results. If you wish, you can filter your results so that you only see fixed or variable tariffs - so what’s the difference? And what's a standard variable tariff?

Fixed rate tariffs mean that the price you pay per unit of energy will stay the same for the duration of your plan. (The more energy you use, the bigger your bill - but the unit price is fixed.) Fixed rate tariffs usually last between 12-24 months.

They’re often good value and usually cheaper in the long term than variable rate tariffs. Plus, if prices go up you won’t be affected until your contract ends. Equally, though, if prices go down you’ll still have to pay the same amount. Fixed tariffs can have exit fees, too, if you want to end your contract early.

Variable tariffs mean that the price you pay per unit of energy isn’t fixed. Prices might go up or down depending on wholesale energy prices, but this isn’t the only factor - providers can change the price whenever they want.

If you’re on a variable tariff, you’ll benefit if wholesale costs drop and your supplier reduces its prices. You can also switch at any time without having to pay exit fees. These tariffs are best for people who keep a close eye on their bills: they often start out being competitively priced and there are savings to be made, but if you don’t switch when prices rise, you’ll end up paying more.

Standard variable tariffs (SVTs) are the basic plans offered by suppliers. If you move house, or your fixed tariff finishes, this is usually the default tariff you’ll find yourself on unless you specify otherwise. The rate is often the most expensive, which is why it pays to switch regularly.

What other types of tariff are there? 

Once you’ve decided whether to choose a fixed or variable tariffs, there are a number of other tariff types it’s worth knowing about. Here’s a brief run through…

  • Dual fuel tariffs are those in which you receive your gas and electricity from the same supplier. Often you’ll get a discount for sticking with the same supplier for both (but not always).
  • Single fuel tariffs are, as the name suggests, those in which you receive one type of energy from one supplier. Many newer properties only use electricity, for example. 
  • Multi-rate tariffs mean you’ll pay less for energy consumed during the night.
  • Prepayment tariffs are those in which you pay for energy before you use it, via a prepayment meter. These tariffs are usually more expensive than others.
  • Economy 7 and 10 tariffs are plans in which you pay different electricity prices depending on the time of day (they’re not available for gas). Economy 7 tariffs give you seven hours of cheaper electricity - typically at night; Economy 10 tariffs give you 10 cheaper hours - usually seven at night and three during the day. The cheaper hours of electricity can be around half the price of normal energy plans, but check the rates for the remaining hours as they often cost more than other plans.
  • Green tariffs use renewable energy. Many tariffs now offer 100% green energy as standard, but green gas is currently tough to supply at scale, and many tariffs offer up to 100% carbon offsetting instead. Exactly how ‘green’ a green tariff is can vary dramatically, so always check the fuel mix before switching.

How often should I run an energy comparison? 

It’s a good idea to run an energy comparison at least every 12-18 months. If you’re on a fixed tariff, always compare energy prices before your contract ends. Your switching window opens 49 days before the end of your contact, which means you can switch any time within that period without incurring exit fees.

However, even if you’re on a fixed contract, it can be beneficial to run a price comparison mid-contract to check whether prices have fallen and what sort of deals are around. The potential savings from switching may be far greater than the exit fees.

How do free energy comparison sites make money? 

Energy comparison sites earn a referral commission from a supplier every time someone switches. It doesn’t affect the price of your quote: you’ll see the same price whether you switch through the energy comparison site or go directly to the supplier. The unit cost of energy is the same via either route. 

Bear in mind that while most energy suppliers are very happy with this set up, not every provider chooses to enter into this agreement. You'll still be able to see tariffs from these providers in your results, but because the energy comparison site can’t switch you to them, it might not show these plans by default. To see them, you’ll need to filter your search results to show all plans, and if you decide to switch to one you’ll need to contact the supplier directly.

How to choose the best energy comparison site 

The best energy comparison sites - like ours - are Ofgem-accredited, so make sure you look for confirmation of this before choosing a service. It means the energy prices and options you’re shown have been calculated fairly, in an unbiased way – and that the service will have an effective complaints process, too.
