Comparing energy suppliers could save you money on your bills, particularly if your current plan is coming to an end. It’s an essential part of looking for a new energy deal.
There are many energy comparison sites to choose from. We use the Uswitch engine to look at multiple providers simultaneously, which helps give you a complete picture of the sorts of prices you could be paying as well as which suppliers and tariffs offer the best value.
“My dual-energy plan was coming to an end. I was with npower, who I always thought were cheap but then they were bought over by E.ON Next. Not really knowing much about them and not having a choice to go with them either I had no loyalty to stay. So I investigated to see what my new tariff plan would look like and it was a lot higher than my old plan.”

This is a common theme. Energy suppliers usually roll you onto a more expensive variable deal when your current fixed-price deal comes to an end. That’s one key reason to consider switching your deal regularly.
You should also look at other factors to help determine the best energy deals and suppliers for your individual needs. An energy comparison includes all these criteria in its results, but you should check our individual energy supplier guides too.
We cover a huge range of suppliers so you can find the very best deals. The providers we list include:
Green Network Energy
Plenty of leading names will offer you single-fuel deals on either electricity or gas, including:
Most suppliers offer plans with smart meter options. Some plans offer cheaper prices if you have a smart meter or agree to have one fitted.
Be aware that some older smart meters become “dumb” once you’re no longer with the energy supplier who installed them. You can still use them to monitor your usage, but you need to manually submit regular meter readings. This applies to the old SMETS1 smart meters.
Any smart meter currently being installed should be a SMETS2 meter, which works with all suppliers, but it’s worth double-checking that this is the case.
Note: you won’t need to replace your older SMETS1 smart meter with a newer SMETS2 model – the plan is to roll out software upgrades to SMETS1 meters to make them compatible with all suppliers.
Just follow these four simple steps:
Providing information on your physical location enables us to narrow our search to the energy suppliers and tariffs that are available in your area.
Let us know how much you pay or how much energy you use each month so our quotes can best reflect your estimated monthly cost.
We list all the best deals around. You can filter them by fuel, payment method, plan type and more – just pick the one that’s best for you.
All we need is your address and bank details to get the ball rolling on your energy switch, which will be complete in just 21 days.
There are a number of options which determine the structure of an energy plan. With our comparison, you can filter them by the following options:
Fixed-price energy plans ensure that the price you pay per unit of energy stays the same until the end of your contract. Variable energy plans are subject to change, so your unit prices – and thus your energy bill – may go up or down, even if your usage remains constant.
Single-fuel plans are aimed at those who only use electricity or gas, while dual-fuel plans are targeted at those who use both.
Exit fees are usually added to some (but not all) fixed-price energy plans to guard against customers leaving the plans early. You can still leave, but you’ll have to pay a certain amount for each fuel. Some plans – including most variable plans – don’t come with exit fees, and you can filter your results to view only those that don’t charge an exit fee if you prefer.
You can pay for your energy in a variety of ways:
monthly direct debit
when billed using a debit or credit card or a cheque
in advance by topping up a prepayment meter
Energy providers are increasingly moving towards green energy sources, but if you want to be 100% sure your gas and electricity is green you can use our handy filter.
Sometimes. People often think a dual-fuel plan is cheaper than two separate plans, but this isn’t always the case. It’s certainly more convenient going with a single supplier for both gas and electric, as the start date for your fixed plan will be the same for both, making switching a lot easier going forward. But the choice is yours – compare potential plans to see which offers the best value.
Renewable electricity can cost more if your supplier requires you to pay a premium for it, either as a special plan or as an added fee on your current plan – however, 100% renewable electricity plans are becoming increasingly commonplace and price-competitive. Green gas is harder to generate than electricity, so you may be looking at higher monthly costs for any gas that is renewable.
Don’t worry, any customers of a failed energy company are automatically transferred to a new supplier. Your energy supply won’t be interrupted, but it does mean you’ll probably end up on the new supplier’s “deemed tariff”, which is generally an expensive standard variable tariff. If you think your energy supplier has gone bust, check with Ofgem. Its advice is to wait until the new supplier is in place, but you should sort out an energy switch as soon as possible so you don’t end up spending more than necessary.
You can make an energy switch at any time. If your contract comes with exit fees it’s best to change suppliers once you’re in the “switching window”, which starts 49 days before the end of your contract. If you change outside of this period, you have to pay the exit fees, but once you’re in the switching window, you can move to a new tariff or supplier without penalty. If you’re desperate to switch outside your switching window, look for a supplier that’s willing to pay some or all of your exit fees in return for gaining a new customer.
You should read your tenancy agreement carefully to find out if you can change energy suppliers in your rented property. If you’re responsible for paying your energy bill, your landlord should allow you to change supplier. If the landlord is responsible, you’ll probably have to stay as you are.
These are special “multi-rate” energy plans that price electricity differently at peak and off-peak times. Economy 7 gives you seven hours of off-peak pricing, and Economy 10 gives you ten. You’ll need a special meter fitted and you need to be able to move most of your energy usage to these lower-priced night-time hours to make worthwhile savings.
You can change suppliers in any way you see fit, either from dual-fuel to two single-fuel plans or vice versa. While it’s possible to have separate suppliers for single-fuel electricity and gas-only plans, you can’t switch the tariff or supplier for just half of your dual-fuel plan while carrying on as normal with the other half.
Every 28 days – this doesn’t mean early exit fees won’t apply, though, so check your fixed-price plan carefully to see whether you’ll be liable.
