E.ON Next business energy features

Below is more information on the features and tariffs available with E.ON Next business energy.

Customer service

If something goes wrong with your energy, it can be calamitous for your business, meaning good customer service is a must. In fact, based on NerdWallet’s survey, 24/7 customer service is the single most important factor business owners look for when choosing a supplier.

That’s why it is unfortunate that E.ON Next doesn’t provide 24/7 customer service, unless you have an emergency with your prepayment or credit meter. If you do, you can call 080 501 5088, email, or get in contact with the supplier over social media.

Nevertheless, E.ON Next does have a range of contact options if you do need help with your business energy. You can contact E.ON Next on the following:

  • Email: [email protected], 8am to 10pm Monday to Sunday
  • Phone: 0808 501 5699, 9am to 5pm Monday to Thursday, and 9am to 4pm on Fridays
  • Facebook, Twitter and WhatsApp, 8am to 10pm Monday to Sunday

You can also manage your business energy through the free E.ON Next app.

Business energy tariffs 

Meeting an organisation’s specific energy needs is a must for business owners. Only 24/7 customer service and the ability to pay by direct debit were more important when choosing a supplier, according to NerdWallet’s survey.  

E.ON Next offers bespoke business energy tariffs to its customers – but only to businesses of a certain size. To be eligible for an E.ON Next business energy tariff, your organisation needs to use up to 100,000kWh of electricity and/or 293,000 kWh of gas a year, have a turnover of less than €2 million, and employ fewer than 10 people.

Any businesses bigger than that will need to source their energy elsewhere. If you want to stay with E.ON Group, that would mean looking at npower Business Solutions.

Bespoke business energy tariffs

E.ON Next offers bespoke fixed-rate tariffs designed to cater to your specific business needs, with 100% renewable electricity as standard if you sign a contract directly through the supplier. 

A fixed business energy tariff means that, while your monthly bill will rise and fall based on your usage, the price you pay for per unit consumed stays the same for the length of your contract.

Deemed, variable and out-of-contract rates

If your energy is supplied by E.ON Next, but you have not signed up to a tariff with the supplier, you will be put on a deemed contract. This could be if you have moved into a new business premises supplied by E.ON Next without arranging a new tariff.

Similarly, if you let your E.ON Next contract expire without renewing it you will be placed on a variable price plan.

Variable and deemed rates are typically more expensive than fixed-rate contracts. However, if you are on a variable or deemed rate, you can move to a fixed tariff at any time, whether with E.ON Next or a different provider.

If you decide to stop getting your electricity and gas from E.ON Next, but are yet to sign a contract with a new supplier, you will be placed on an out-of-contract rate that is more expensive than the variable price plan.

Additional fees and charges

It is important to remember that on top of your kWh usage, charged at your unit rate, you will pay:

  • a fixed standing charge, which contributes towards maintaining the electricity network
  • VAT, either at 20% or the reduced rate of 5% (if your business uses less than 33kWh of electricity or 145kWh of gas a day)
  • the Climate Change Levy (CCL), though there are exceptions to this tax

You may also be charged for third party, non-energy costs that may vary from month to month. These can include:

  • energy infrastructure costs
  • low carbon generation costs
  • National Grid energy-related costs
  • security of supply costs

Payment options

While E.ON Next encourages businesses to set up a direct debit – the most important payment option a supplier can offer, according to NerdWallet’s survey – for ease of use and to potentially save money, that isn’t the only way you can pay your energy bill. You can also:

  • make card payments online and over the phone
  • make a bank transfer
  • pay by cash over the counter at your local Post Office, as well as Payzone and Paypoint locations
  • send a cheque in the post to E.ON Next, PO Box 10909, Nottingham, NG1 9NJ

Smart meters

Having a smart meter at your business can help you become more energy efficient, therefore potentially saving you money in the long run. Business owners are well aware of this – it’s why smart meter installation is in the top five most important services they are looking for in a supplier.

With E.ON Next, getting a smart meter installed is simple. All you need to do is book a smart meter appointment, either through the website or over the phone on 0808 501 5266, and E.ON Next will take care of the rest.

Renewable energy options

E.ON Next provides 100% renewable electricity at no extra cost if you sign or renew a contract directly with the supplier. This is through E.ON’s own renewable assets, agreements with other independent renewable generators in Great Britain, and the purchase of renewable energy certificates.

Each megawatt hour (MWh) of the renewable source electricity it supplies is backed by Renewable Energy Guarantee of Origin (REGO) certificates. REGOs are a requirement of the Office of Gas and Electricity Markets (Ofgem), as part of the fuel mix disclosure regulations.  

While REGOs aim to give transparency to consumers about the amount of renewable energy that a company has used, sourcing directly from renewable generators is a stronger sign of a commitment to renewable energy.  

Customer reviews

E.ON Next has a ‘Great’ Trustpilot rating of 4.2 out of 5, based on 43,511 reviews (as of 16 January 2023). It is important to note that this rating is based on the entire E.ON brand, not just on their specific business offering.

How can I switch to E.ON Next business energy?

  1. First, you need to make sure you are at the end of your contract with your current supplier, and have satisfied any notice period.
  2. Then you need to call E.ON Next and get a quote.
  3. Once you have chosen your tariff, E.ON Next will work with your current supplier to get your business switched over, including sending your final meter readings. Your switch will go smoother if you have already cleared any outstanding balance with your existing supplier.
  4. Once the switch is complete, E.ON Next will then let you know when to submit your opening meter readings.

How to choose an E.ON Next business energy tariff

When comparing E.ON Next and other business energy suppliers, it is worth asking yourself the following:

  • Do you want a fixed-rate or variable tariff?
  • Do you want renewable electricity or carbon-neutral gas?
  • How long do you want your contract to last?
  • What level of customer service do you want the supplier to offer?

Moving business premises with E.ON Next business energy

Whether you’re moving into premises supplied by E.ON, or looking to leave them entirely, E.ON Energy can make the move easier. Here’s how it works.

You’ll need to provide the following:

  • moving-out date
  • final meter readings on move-out date
  • forwarding address
  • landlord’s details for your new address

Moving into premises supplied by E.ON

If you’re moving into an office already supplied by E.ON, it will get in touch to welcome you to the premises and help to set up your account.

You’ll need to provide the following:

  • your name, business name, and type of business
  • contact phone number and email address

Review methodology

At NerdWallet UK, we base our reviews and our ‘Best’ pages on the results of surveys we undertook about what was important to people who use these products. This allows us to look at products impartially of any commercial arrangements we have and fairly rate the products on the same set of criteria.

Best means our ‘Best’ and is based only on what products we have aligned to our surveys, which form the basis of our reviews and ratings. This means that there will be other products on the market that we have not included in our ‘Best’ pages. Best does not mean it’s best for you, nor does it mean the ‘cheapest’.

Our reviews may display lenders’ rates. This additional information has not been included in our evaluations but is still very important when choosing a product. Rates offered can depend on circumstances, amount and term. Always check details before proceeding with any financial product.

Product details reflect the information that was available at that time but may have changed since. We strive to give you a review on as many products as possible, but there will be products not included on the market. The review is our opinion, but it does not constitute advice, recommendation or suitability for your financial circumstances.
