If you're looking for energy switch deals for electricity and gas, then you're at the right place.

Thinking of switching energy suppliers?

Whether you're looking to save money by switching your tariff or want to enjoy the benefits of dedicated customer service, there are many reasons you may be considering switching utility supplier.

Thankfully with us switching is simple. Hear from real customers on their experiences joining E.ON Next.

So, how do I switch energy suppliers online?

Well the answer should hopefully be: easily! All you need are the details of your current energy tariff - such as who supplies your electricity and gas and how much energy you use. With that in hand, switching your energy is simple.

Better yet, if you're joining us, you can complete the entire switch online. From getting a quote to submitting your first meter reading. But if that's not quite your cup of tea, our dedicated Energy Specialists are on hand to help guide you through.

Switching to an energy supplier and tariff is as easy as 1, 2, 3...

11. Check who supplies your energy

22. Work out how much energy you use

33. Get a quote and sign-up

We'll talk you through what you need to do every step of the way. Plus, you can find the answers to some common questions and situations that crop up from time to time at the bottom of this guide.

Your energy switch in 4 simple steps.

Step 1 - Who is your current energy supplier?

In most cases, you'll know who your current energy supplier is. You've either been with them for years or made a switch more recently.

However, in some cases, such as buying a new home, you might be left wondering who on Earth is powering your home.

If you're not sure who supplies your energy don't worry, we've got you covered.

First things first, check your recent electricity and gas bills if you have them. Your current supplier's name and contact information will be listed on all your bills.

Who is my electricity supplier?

You can contact your energy network operator directly to find out who supplies your electricity. Use the Energy Network Association search tool to find your energy network operator. Then get in touch to learn your electricity supplier and your MPAN (Meter Point Administration Number), which is used to identify your electricity meter.

Who is my gas supplier?

You need to talk to the Meter Point Administration Service, either by using their online Find My Supplier search tool or calling them on 0870 608 1524. They can also tell you your MPRN (Meter Point Reference Number, which is used to identify your gas meter).

Step 2 - How much energy do you use?

It's a good idea to enter your actual energy use figures when getting a quote. The estimated monthly payments will be more accurate to your lifestyle, helping you to choose a tariff with confidence.

The easiest way to find your annual energy use is by checking a recent energy bill. It should show your estimated annual electricity and gas usage, calculated based on your energy use to date.

However, if you can't find how much energy you use, you can always use Ofgem's average figure for your home's size. This will still give you a rough idea of how much you would spend each month as part of your quote. It's a good rule of thumb, but keep in mind that you will pay for all the energy you use once your new tariff starts - not what is on your quote.

Step 3 - Getting a quote.

Looking to switch to E.ON Next? It's quick and easy to get a quote online. If that's not quite your style, try talking to one of our Energy Specialists.

There are a few important things to do when you request a quote:

  • Pick the correct meter type. This can affect which tariffs you're eligible for and the prices available to you.

  • Choose your preferred payment method. Your payment method can affect your energy prices. You'll be charged based on the payment method you actually use, not the one you select in your quote.

  • Enter accurate energy use estimates. We know we've covered this already, but it's really important to avoid any nasty surprises in your budgeting.

Not sure which energy tariff is right for you? Here are key features to consider:

  • Is it a fixed tariff, standard variable tariff, or a tracker tariff - like our Next Pledge?

  • Does the tariff offer 100% renewable electricity?

  • Will you get dedicated customer service?

  • Are there early exit fees?

  • Do you need to have a free smart meter installation?

  • Can you pay by Direct Debit to help spread the cost of your higher winter bills over the year?

Once you've picked your tariff, all you need to do is sign-up!

Step 4 - Do I need to do anything during the switch?

The last step for you to take to help complete your switch, is to send your new supplier your opening meter readings. To keep things nice and simple, they'll send you a reminder on when to take it.

You don't need to get in contact with your old supplier. They'll be sent your meter readings by your new supplier, so they can close down your account and refund any credit that's due.

It can take up to 5 working days for your electricity and/or gas supply to move over to your new supplier. You'll also have a 14 day cooling-off period, in case you change your mind and want to stay with your current supplier. Your options will differ depending on whether you join your new supplier in your cooling-off period or not.

Switching is easy today.

Just ask our customers.

We'll always go that extra mile for you, but don't take our word for it, check out what our customers have to say. Once you switch your electricity and gas to us, you could be just as happy.

May 2025

I changed tariff because I recently had an EV charger installed and I was recommended to have the off-peak tariff; overnight charging of the car would be a quarter of the price compared to the peak kwh price. It was so simple to change to this tariff on my account, and it took effect the same day evening Well done E.ON!

What happens if I change my mind and don't want to switch suppliers?

If you no longer want to switch, you must contact your new energy supplier as soon as possible to let them know. If your switch has not been completed it should be able to be cancelled completely at this point, and you will stay with your previous energy supplier.

You have a 14 day cooling off period from the date you sign-up to your new tariff, to change your mind. If you want to cancel your switch after this period you may have to pay exit fees. Check your new contract to find out if it's subject to exit fees.

As switching your energy supply can now happen in as little as a single working day, you may find that your switch is completed before the end of your 14 day cooling off period. You can still choose to cancel your switch and be returned to your previous supplier, but you'll need to pay for any energy you used with the new supplier.

Once you have requested to cancel your switch, you have 15 days to arrange an alternative energy supply. You can choose to:

Switch back to your previous supplier

Switch to a different supplier

Stay with your current supplier on a new tariff

During this period your current energy supplier must continue to supply energy to your property, so there won't be any interruption to your gas or electricity. Keep in mind that you will be charged for the energy you use.

Get answers to your switching supplier FAQs.

Are there exit fees when switching?

If you're on a variable tariff which has no fixed end date then you shouldn't have to pay any exit fees if you switch suppliers.

If you're on a fixed tariff then you'll need to check the terms of your current contract, as you may be subject to exit fees if you switch before the end of your fixed term. The good news is, if you're nearing the end of your contract you do have some flexibility to switch early without a penalty. If you're within 49 days of your fixed tariff ending you cannot be charged exit fees even if they apply to your contract.

Is it easy to switch supplier?

We've made it as easy as possible to switch your energy supplier. Simply follow our step by step process and we'll send you reminders of what we need from you along the way.

Better yet, if you're switching to us the whole process can be completed online - from requesting a switch, to getting a quote, to sending us your opening meter reading. To get started, all you need is your latest energy bill and an idea of how much energy you typically use.

How long does it take to switch energy suppliers?

Depending on your meter type, you may be able to join E.ON Next in as quick as 1 working day.

Unlike us, not all suppliers offer a 1 working day switch. If you are leaving or joining one of these suppliers your switch could take up to 5 working days to complete - even if the other supplier offers faster switching.

Most suppliers will offer you the choice to join right away or will ask you to wait until the end of the 14 day cooling-off period before starting the switching process. However, you can arrange to switch at a later date if that better suits your circumstances.

I missed my 15 day cancellation window. What happens now?

If you don't agree to a new contract within the 15 day cancellation period, you will automatically be moved onto the default standard variable tariff of the supplier you were originally switching to. In most cases these default (also known as deemed) tariffs do not have exit fees, but you should always check with your new supplier.

If you are moved to the default tariff you can choose to return to your previous supplier by arranging to switch your tariff again. However, your previous supplier will not be obligated to offer similar terms when agreeing a new contract with you once the 16 day period has ended.

Why can't I switch suppliers?

There are a number of reasons why your switch to a new supplier might be blocked. It's best to speak to your current energy supplier to find out the reason why and what you can do about it.

You can find your current suppliers contact details online or on your energy bill.

How much can I save on bills when switching tariff or supplier?

When comparing energy prices, it is essential to ensure that you are comparing like for like. Several factors can affect your energy prices, including your chosen payment method and tariff type. To ensure you get an accurate comparison, we recommend you choose which payment method and tariff type is right for you before you start comparing quotes.

Is it worth switching energy suppliers now?

There are many reasons you may benefit from switching your energy supplier now. If you think you may be able to get a better deal on your energy, we recommend comparing like for like quotes with your current energy tariff.

Can I switch energy supplier at any time?

If you're not happy with your energy supplier or you would like to change your tariff, you can choose to switch at any time. However, you may be subject to exit fees. Always check your current contract before switching to avoid unwanted surprises.

Will I be paying for two suppliers when the energy switch takes place?

You won't be double charged at any point during your energy switch. In the vast majority of cases, as soon as the switch takes place you will start paying your new energy supplier, and stop paying your previous one.

Will my energy supply be disrupted during the change in suppliers?

Switching energy suppliers will not cause any disruption to your energy supply. The energy you use all comes directly from the grid - no matter who your supplier is. So, the only change you will notice is who sends your energy bills and how much you are paying.

Can I change electricity and gas suppliers if I am in debt?

How long have you been in debt to your current supplier? If it's less than 28 days and the amount is less than a certain threshold, you may still be able to switch. Contact your supplier for more details.

Can I change electricity and gas supply when moving home?

Yes, you can start your switch on the day of your move or at any point afterwards. Simply get in touch with the supplier you want to join and they can help manage your switch.

I rent my property, can I switch energy provider?

If you rent your home there are two ways you may pay for your energy supply: directly to an energy supplier or to your landlord as part of your rent. If you pay directly to an energy supplier, you can switch at any time.
