How to compare energy tariffs and suppliers

Looking to switch your gas and electricity tariff? There’s lots to consider – from the best tariffs for electricity to the cheapest dual fuel deals. We’re here to help you choose. 

Find the best energy deal for you

Switching energy suppliers isn't just about finding the cheapest deal. You need a tariff that's right for your home, your family and your lifestyle. So with plenty of suppliers to choose from, it's important you spend a little time finding out which one could be right for you.

Do you need a fixed-energy tariff for a set rate throughout the year? Or if you don't use gas at all, maybe an electricity-only tariff would be best for you.

Whatever you need, our step-by-step guide will help you choose the right supplier and find the best deal.

How to choose an energy provider

Follow these steps to find the right deal for you.

1. Review your current energy deal

Take a look at a recent bill or statement. Are you paying separately for gas and electricity? Having a single supplier can be more convenient, and sometimes it’s slightly cheaper. Check out the benefits of a dual fuel tariff.

Even if you want to pay for gas and electricity separately, it is still worth comparing suppliers to find the best deal for you. 

2. Understand how much energy you’re using

Your choice of tariff might be affected by how much energy you use, so before comparing different tariffs, log into your account and take a look at your last few energy statements or bills to find your average energy use. This should help you work out which tariff is right for you.

How much you use depends on your lifestyle, your home’s size and how many people you live with. Check out our average energy bill guide to find out more.

3. Compare tariffs to find the best energy deal

Take a look at energy comparison sites or phone different suppliers to understand what gas and electric deals they offer.

You might want to think about different types of tariffs:

What's a fixed price tariff?

It guarantees your rates will stay the same for the length of your contract, so you'll be protected from the changes of wholesale energy prices.

What's a variable tariff?

This is usually a supplier's default rate - your energy prices will go up and down as the costs of gas and electricity change. Therefore, it's worth contacting your supplier to see if a different tariff can save you money.

Should you switch to a green tariff?

Choosing a green tariff helps you reduce your carbon footprint as providers buy more energy from renewable sources.

Some green tariffs also help to develop more natural energy sources like wind, solar, tidal or biomass.

Compare similar energy tariffs

With so many tariffs on the market, it's important to be sure you're comparing similar energy tariffs. If not, you'll need to take their differences into account when you make your decision.

For example – a tariff with no standing charge might have higher prices per unit but could still be cheaper overall.

4. Consider your payment method

Direct Debit

This is the easiest way to pay for your energy. Energy suppliers usually offer the best rates if you pay this way.

Pay As You Go meters

PAYG meters let you buy your energy upfront so you’ll never get a bill that you can’t afford.

Pay via monthly or quarterly bills

You’ll see how much energy you’re using. But it’s not normally the cheapest option.

5. Weigh up your options before you switch energy supplier 

Online or offline

If you’re happy to manage your energy account online you could save money with an online tariff. Think about whether you find the provider’s website easy to navigate or if they have an app. From here you should be able to:

  • Send meter readings
  • View and pay bills or statements
  • Contact customer service
  • View your previous bills or statements
  • Change your billing information and any other account details

If you’d prefer to receive your statements by post, switch to a supplier that offers this too.

Exit fees

Some energy suppliers charge exit (or cancellation) fees for leaving a fixed-term contract early.

 Make sure you do the sums before leaving. If the potential saving is less than your exit fees, it's probably not worth switching. But some energy providers will offer to pay your exit fees if you join them - it's worth checking.

 It could be worth waiting for the last 49 days of your current deal. Remember that exit fees don't apply during the last 49 days of a fixed-term contract.
