Are you an existing EON customer?

If you’re already an Eon customer, you’ll have different questions than if you’re a new customer looking to switch. Hopefully, we can help with all of your questions, so existing customers keep reading, and potential customers keep scrolling to find out more.

Eon account login

Existing Eon customers can see everything they need to know about their account by entering their email address or username and password.

It’s great having an online account because it means you can be kept up to date with any changes and submit your meter readings. By submitting your readings regularly, you can avoid paying more for energy that you’re not using. You can find out more about your tariff, usage, and bills and make changes to your account.

Register for your online account with your postcode and account number to get yourself set up.

Login to my EON account

Why can’t I access my Eon online account?

While it may sound silly, the number one reason customers can’t access their account is usually that they’re using the wrong login details. It’s important to use a username and password you’ll remember to make sure you can get in every time. If you change your password regularly, keep track of when it was changed which might help you remember what you changed it to. If you’ve entered your details wrong five times, you may also be locked out of your account for security reasons.

However, this isn’t the only reason you might not be able to access your account. If you’re still having trouble, try resetting your account with your account number, postcode, email address, and phone number and make sure you’re all set up. You might not have set up an online account yet.

If you still need help, get in touch with Eon at 0345 052 0000 with a bill to hand.

Eon top-up help

If you haven’t had a top-up meter before, you might have a few questions about how it works, especially when things go wrong. With thousands of prepayment customers under their belt, Eon has made it easy for you.

Q – How do I top up my card/key?

Topping up your gas and electricity with a prepaid key is easy. Simply take it to a shop that offers PayPoint or Payzone, or pop to the Post Office and they’ll do most of the work for you. All you have to do when you get home is put the card or key in the meter. Just make sure it’s registered to your meter before you top up by putting the key in until it beeps.

Q – I’ve run out of gas/electricity and can’t afford to top it up until payday. What can I do?

There’s nothing to be worried about! Your meter will provide you with £5 emergency credit to use when you run out until you can afford it. Simply insert your key into the meter if you’ve got less than £1 of electricity credit left, or £2 gas credit and it will be added automatically. Press red button ‘A’ if you need the credit for gas. The credit will be taken from your next top-up, so make sure you put a little extra on next time to cover it.

Q – My top-up hasn’t gone onto my meter. How do I get it to go on?

Sometimes your top-up will not have automatically registered. If you have a smart meter, you can follow the below instructions to manually enter your top-up.

For smart gas top-up

  1. Press the A button to wake up the screen, then press it again twice to enter ‘Credit Entry’ mode
  2. Press the B button, then A to enter your code and B to move forward
  3. Press and hold the B button to submit your top-up

For smart electricity top-up

  1. Press and hold both the A and B buttons together Use the A button to enter your code and B to move forward
  2. Press and hold the B button to move back
  3. Press and hold the A button to accept and submit your top-up

If you have a traditional, non-smart meter or you’ve followed the above instructions for your smart top up and it hasn’t worked, you should contact EON.

Q – Is an Eon prepayment tariff right for me?

Prepayment tariffs can sometimes be more expensive than other tariffs, however, it ensures that you’re only paying for energy you use. Because everyone uses their gas and electricity differently, a prepayment tariff will be better for some than others. Make sure you compare the different tariffs available and view your usage with Eon See to decide.

To make sure you are on the right tariff for you, please call 020 3992 7717.

What is Eon See and how do I use it?

Eon See is a handy tool in your online account that lets you see how much energy you’re using. Your energy use graph will show how your energy use changes monthly throughout the year. By logging into your online account using your email address or username and password, you can see how much you’re spending and see where your energy is being used.

If you’re a new customer, you’ll have to wait until you receive your first bill before you can use it.

I’d like to upgrade to an Eon smart meter

Smart meters are the newest way to keep track of your energy bills and usage. A smart meter automatically sends meter readings to your energy company so you don’t have to. It makes it so much easier and can even save you money if you’re likely to forget to submit your readings.

Your smart meter comes with a small in-home display which can show you all kinds of different data in real-time, for example, how much energy you’re using and how much you’re spending each day. It allows you to set budgets and compare your energy use so that you’re in control of what you’re spending and how you’re spending it.

Smart meters are on the rise around the UK and are soon set to be in everyone’s homes. They’re a great help in reducing carbon emissions and decreasing the effects of climate change.

Before you request your smart meter, don’t forget:

  • You must inform engineers in advance if there are difficulties accessing your meters or your property or there’s no available parking.
  • If you miss your installation appointment you may be subject to a fine.
  • During the installation process of your smart meter, your electricity will be switched off for around 1 – 2 hours.
  • Smart meters are free to install but there may be a charge to have it removed.

Automatic meter readings!

Did you know that with a smart meter you’ll never have to submit a meter reading again! 100% accurate bills, all the time. Give us a call to find out more about automatic meter readings.

How to top up an Eon smart meter manually

If you’d rather top up your Eon smart meter manually, you can still do so by getting a voucher from the Post Office. Some people might prefer to top up with a voucher as it comes with physical evidence that you have topped up, just in case anything goes wrong.

To top up an Eon smart meter manually, all you have to do is follow these 4 steps:

  1. Press A on your meter to bring up ‘vend mode’
  2. Enter the code on your voucher
  3. Press B to confirm

If you mess up any of the digits when typing them in, you can press A to delete a digit or two and carry on.

Why does my Eon smart meter keep beeping?

If you have a smart prepayment meter, the reason your Eon smart meter keeps beeping is probably that you’re running low on credit (one of the handy features of a smart meter).

To stop the beeping, all you have to do is top up again or activate your emergency credit, which you can do through the app or your in-home display.

What is Eon Heat?

Eon Heat is a new way of heating your home and water. The water is heated by a range of fuel sources and technologies, including Combined Heat and Power. This means that it’s both lower carbon and more sustainable. It uses a local energy centre, managed and maintained by Eon and pumped through insulated pipes to reach your home.

Instead of using a boiler, you will have a Heat Interface Unit which provides heat and hot water instantly as and when you need it. It’s the same size as a boiler, but you’re given a controller to use when you want your heating on, off, or at a different temperature at the touch of a button.

Currently, there are only a select number of heat networks registered with Eon and Heat Trust, but this is set to grow massively in the near future. Heat networks form an important part of the UK’s plan to reduce carbon and cut heating bills for customers.

Eon only offers one plan for this kind of heating – paying a fixed monthly rate. Your bill will be made up of three elements: heating cost, energy service charge (for maintenance, helplines, and investments in the network) and VAT.

The Heat Networks Investment Project is offering capital investment support to increase the number of heat networks across the country and help create conditions for a sustainable market that can run without government subsidy. The Heat Networks Delivery Unit are also offering authorities funding and specialist guidance to those who want to develop heat network projects.

Eon Reviews

With over 20 years’ experience in the market, Eon have, of course, had plenty of time to perfect their customer service and reputation, which they’ve done well. With high scores across the board, they seem to have secured a great place in the public’s mind.

Positive reviews tend to be about the ease of switching energy companies and booking an engineer. A lot of these are also praising engineers and their friendliness and helpfulness. With so many people using review boards to simply complain about services, having 50% of Eon Trustpilot reviews at 5* really reflects their customer service values.

Recently, multiple negative Eon Trustpilot reviews are coming from the installation and use of smart meters. Some about having to have them reinstalled or having trouble using them, some with concerns about appliances not turning back on properly afterwards. However, Eon has replied to over 75% of their negative Trustpilot reviews (2* or less), offering help and advice.

Solar energy tariffs

Eon have a range of different tariffs available to suit everyone. Whether you prefer prepayment, fixed, pay as you go, or variable tariffs, all come with some great benefits. But they also offer discounts on their tariffs if you choose to go solar. Not only do they offer a discount, but they also have tariffs available to pay you for any energy you don’t use to export to the National Grid – 5.5p per KWh. That’s one of the highest of all the main energy companies.

Don’t want to give it back to the grid? Eon can supply you with batteries to store your unused solar energy for an almost literal rainy day.

They are able to supply and install your solar panels for you and have a number of different payment options. You can pay for your panels in easy, 0% interest instalments starting at £111 per month over 3 years. Or you can pay for your solar panels in smaller amounts over 10 years at 7.9% APR. Or, of course, you can pay for the panels and installation upfront.

Fuel mix

All electricity providers in the United Kingdom are now required to disclose their Fuel Mix Disclosure (FMD), which is the source of generation for their electricity supply. This is a particularly pressing topic at the moment due to climate change targets and high fines at country and industry level for not meeting certain levels of renewable energy generation.

Eon has recently started offering 100% renewable energy as standard on all their tariffs, leaving their Fuel Mix looking like this:

In order to make their fuel mix more sustainable, Eon have invested in more efficient forms of electricity generation, such as wind, solar, and biomass. They’ve invested heavily into greener generation and research into more advanced methods to reduce carbon emissions.

Warm Home Discount

Eon do offer the Warm Home Discount on all energy tariffs that they provide. The Warm Home Discount is a payment of up to £140 for customers in England, Scotland and Wales off their electricity bills to combat fuel poverty in the winter months.

Not all customers are eligible for the Warm Home Discount, you must meet certain Government-controlled eligibility criteria. This is categorised into two groups:

  • Core group – You (or your partner) are the account holder/bill payer and receive the Guarantee Credit element of Pension Credit. Core group customers should qualify automatically and receive annual communications from Eon detailing this.
  • Broader group – You (and your household) are on low income or receive certain means-tested benefits, such as Jobseekers’ Allowance, Universal Credit or Income Support. Broader group customers will generally have to apply for the Warm Home Discount through Eon each year.

If you would like to learn more about the Warm Home Discount or apply to see if you’re eligible to receive up to £140, then please click the below link to find our Eon Warm Home Discount page.
