How long does it take to switch energy supplier?

After getting your quick quote through Compare the Market, and completing your online application to move to your new tariff or provider, you can begin the switching process. Your new supplier may reach out to your existing one on your behalf, but be sure to check this to avoid any delays to your new service. This will activate your ‘cooling off’ period, which lasts 14 days. From start to finish, you should expect to be up and running with your new energy supplier in around 21 days, but this may vary.

How much can I save by switching energy suppliers?

Switching your energy supplier regularly is a great way to save on your monthly bills. By comparing quotes and switching energy supplier through Compare the Market, you could  save up to £121**. 
The energy market is highly competitive and new deals become available on a regular basis. It’s common to forget or put off looking at your energy tariff, which means you can slip onto a more expensive variable tariff without even realising. 
Variable tariffs are often the most expensive, which means there are potentially huge savings to be made by switching to a fixed-rate tariff through Compare the Market.

**Where a saving can be achieved, 50% of customers could achieve a saving of £121.47 on their dual fuel energy costs, based on Compare the Market data from January 2021 to April 2021.

Can I compare gas and electricity separately?

Of course, while dual fuel is a popular way to keep your energy bundled together, you can compare gas and electricity prices individually. By comparing separately, you’ll find new tariffs available, potentially offering extra savings. Compare now to find the right deal for you.

Which suppliers do we compare?

At Compare the Market, we compare dozens of suppliers to try and find a cheaper deal on your energy. These include all of the Big Six, British Gas, EDF Energy, E.ON, npower, Scottish Power and SSE, as well as plenty of small and medium suppliers who are offering competitive rates to lure customers away from the traditional favourites.

Frequently asked questions

Who is the cheapest energy supplier?

The energy market is extremely competitive, with tariffs and prices changing frequently. The cheapest rates are always moving between energy suppliers – that includes the Big Six as well as the medium and smaller suppliers. This makes it difficult to say for certain which supplier is the cheapest. 

Because of this, it’s important to compare energy suppliers on a regular basis. Letting your tariff slip from a fixed period contract to a variable one is one of the costliest moves in energy, so be aware of when your current tariff is coming to an end.

At Compare the Market, we can help you stay on top of  the latest energy deals from all of our suppliers. You can quickly compare energy suppliers at any time, to find the cheapest energy supplier for you. Or set up energy savings alerts and AutoSergei will do the legwork. You'll never have to spend time searching for our best energy deals again.

Which energy supplier is the best?

Who the best energy supplier is depends on what’s important to you. Is it the supplier who’s cheapest? Has the best ratings? Or is the most environmentally friendly?

With all of these factors, it’s impossible for us to say who the best energy supplier is. What we can do is present you with options to help you make the right choice for you.

It’s important to understand that the energy market is constantly changing. New tariffs are introduced to the market, supplier ratings change and greener energy sources are always in development. For this reason, it’s important that you compare energy suppliers regularly.

Variable tariffs are often the most expensive, which means there are potentially huge savings to be made by switching to a fixed-rate tariff through Compare the Market.

What information do I need to switch energy supplier?

All the information needed to switch energy suppliers can be found on a recent bill. If there isn’t one to hand in your online account or you don't have a paper copy, you can still get a quick quote – it’ll just be based on estimations of your gas and electricity use.

For a more accurate quote, you need to know things like:

  1. the name of your current supplier and tariff name
  2. how much energy you use (this can be in kilowatt-hours (kWh) or in pounds)

Not sure where to look? Read our guide to  understanding your energy bill.

If you’re on a fixed rate tariff and decide to leave before it ends, check to see whether you’ll be charged an exit fee.

How does switching energy suppliers work?

It doesn’t matter who supplies your gas or electricity – it all comes into your home through the same wires, pipes, ducts and cables. All switching means is that the supplier providing it changes. When you make the decision to switch, your new energy supplier will sort out all the details with your existing supplier.

Switching with us is easy, quick and fuss-free. We ask a few simple questions about your energy use and find suitable, available deals based on your answers. Learn more in our guide to the switching process.

Will my gas and electricity be interrupted if I switch?

Your gas and electricity supply will carry on as normal when you switch energy suppliers. The only thing that changes is where your bills come from.

Gas and electricity come into your home the same way, so there’ll be no break in supply and you can get on with counting your savings.

What is the difference between fixed and variable-rate tariffs?

There are two types of energy tariff available:

  1. Fixed-rate tariffs, where the cost of each unit of energy is fixed for a certain period of time, usually 12 months or more – it doesn’t mean the total cost is fixed, as the more you use the more you’ll pay
  2. Variable tariffs, where the cost of each unit of energy you use can go up or down at any time, usually according to the changes in the wholesale energy markets.

Find out more in our energy tariffs guide.

What is a dual fuel tariff, and why should I consider switching?

Dual fuel is a type of tariff where your gas and electricity come from the same supplier. Most people opt for dual fuel deals because of the price, but it also makes life a lot easier – you have only one supplier to deal with and one online account or set of paperwork.

Whether you’re looking to find separate deals for your gas and electricity or a cheap dual fuel tariff to combine the two together, you can compare energy suppliers with Compare the Market to find the best deal for you.

Is it more complicated to switch gas and electricity together?

Switching dual fuel is no more complicated than switching one energy type on its own (and that’s simple when you use Compare the Market).

When it comes to searching for quotes, just choose the option ‘gas and electricity’ if you want to focus on dual fuel.

It helps if you have both your latest gas and electricity bill to hand, from your online account or from a paper bill, because the answers to the questions we’ll ask you will be there. If you don’t have a bill, then don’t worry, we can still run a search based on estimations.

Can I switch energy supplier if I owe money?

It’s always best to sort out any outstanding bills before the official switch date, otherwise, it can make the transition a bit trickier.

When you decide to switch and have got the ball rolling with your new supplier, you should settle any outstanding debts. If you have bills that are more than 28 days old, you might find that you can’t change supplier until you’ve paid them. But there are some exceptions to the 28 days – for example, if you are less than £200 in debt, then your switch could still go ahead as normal.

I'm moving house. How can I switch gas and electricity?

Moving is a great opportunity to reassess your energy deal. If your existing deal is a good one, then it can be carried over to your new home – just tell your supplier the new address and the move-in date.

The day you leave your old home, you should take a meter reading and give this to your supplier – that way you can be sure your final bill will only reflect what you’ve used.

When you arrive at your new home, take a meter reading and make a note of it. You’ll need to find out which supplier provides the gas and/or electricity to your new home and give the meter reading to them. That way, you won’t be paying for the energy used by the previous owner.

When you speak to the existing supplier in your new home, check what tariff you’ll be put on – in most cases, you’ll end up on their standard variable rate, which is usually their default (and often most expensive) tariff.

The one good thing about standard variable tariffs is that they’re flexible and, typically, you won’t be charged an exit fee for leaving. So, once you’ve settled into your new home, you can start comparing energy deals to find one that suits you and your wallet.

Can I switch energy provider if I rent?

Tenants can switch energy providers if they pay the supplier directly for their gas and electricity. Your landlord may have a ‘preferred supplier’ but this doesn’t affect your right to switch.

If your landlord pays your energy bills, then charges you, choosing the supplier is up to them, although you can always ask them to change to get cheap gas and electricity.

Can I get a smart meter if I switch gas and electricity?

It depends at what stage in their smart meter program your gas and electricity supplier is. All energy suppliers must aim to install smart meters in 85% of homes and small businesses in England, Wales and Scotland by 2024. Although the initiative was triggered by the government, the rollout is being managed by individual energy companies.

What that means is that you can get a smart meter if your supplier offers it; or you can wait until they contact you. You can switch supplier in order to get one, but you’ll need to make sure it’s really worth switching just to get a piece of fancy tech.

See more about how smart meters work in our guide to smart meters.

How can I find a green energy supplier?

More people are looking for tariffs that source energy from renewable sources - like wind, wave and solar - as alternatives to energy that comes from fossil fuels. When you compare with us, you can choose to see tariffs for 100% renewable electricity.

See more on renewable energy.

I have solar panels, can I switch a feed in tariff too?

The feed-in-tariffs (FITs) scheme stopped accepting new applications after 31 March 2019. If you are already on a FIT tariff, your service and payments remain unaffected until your solar system is 20-25 years old. All energy suppliers with over 250,000 customers were obligated to join the FIT scheme, including the Big Six suppliers, which means you can switch your FIT tariff between these suppliers without issue. Energy suppliers with fewer than 250,000 customers had to volunteer for the scheme, so you may find fewer options when comparing FIT providers.

A FIT is where you get paid for generating your own energy as well as getting money for selling back excess electricity to the National Grid. Most big energy suppliers are also FIT licensees – which means they are registered and able to make FIT payments. 
The amount of money you are entitled to depends on how much electricity you generate as well as how many solar panels you have. The price is set by industry regulator Ofgem, so switching energy supplier doesn’t mean you’ll receive more money. However, switching could provide a more efficient service, and therefore faster payments, so considering different energy suppliers could still be very beneficial. 

What is the Smart Export Guarantee?

The Smart Export Guarantee (SEG) replaced the feed in tariff (FIT). Like the FIT, it pays you for electricity you generate from renewable sources (such as wind and solar) that you don’t use. But unlike the FIT, the energy company you supply to decides the prices, rather than Ofgem – so it’s worth shopping around to find the best deal. The company you supply to doesn’t have to be the same one that supplies your energy.

How often do energy prices change?

Energy prices change all the time. They reflect market supply and demand, and fluctuate as a result. They're also affected when wholesale costs change. If you have a standard variable rate tariff, your price per unit of energy used will go up and down with the market.

If you want to know what your unit rates are going to be for a set period of time, you can choose a fixed rate tariff from your energy suppliers.

Where do the energy price comparison figures come from?

When you compare with us, we’ll show you a list of tariffs with potential savings. These are based on Ofgem’s personal projection calculation, which predicts what your energy costs would be for the next year if you stayed with your current provider and tariff. It enables you to compare what you’re paying now with other providers so you can make an informed choice.

How do personal projections work with fixed tariff plans?

The personal projection takes into account what your energy costs will change to once your fixed tariff – or any other type of fixed energy plan – ends. It assumes you’ll be rolled on to a standard variable tariff: the suppliers’ default tariff.

If you compare at different times, the figures will keep changing because the time left on your fixed plan and the time you’d be on the new plan will change.

So if, for example, you’re on a fixed plan that ends on 31 December 2021 and you compare in June, your personal projection might be £800 for the next 12 months. If you check again in September, the figures will be higher. This is because there’s less time on your fixed plan and more on the higher standard variable tariff.

Our partner puts together available tariffs and works out potential savings. They’re accredited by industry regulator Ofgem.

When you find a quote that suits your needs, submits your switch application to the relevant energy supplier (like British Gas or npower).

How do energy comparison sites make money?

Each time someone switches their gas or electricity tariff through a comparison site, the site gets paid by the new supplier – you don't need to pay anything to the comparison site for your switch.
