E.ON business deemed rates

For SMEs, the current public business pages are now under E.ON Next. E.ON Next says that if a fixed business contract ends without renewal, the customer rolls onto a variable price plan, and if the customer decides to leave but the switch has not completed yet, they move onto out-of-contract prices. E.ON Next also says those out-of-contract prices are higher than its variable price plan. If a business takes supply without an agreed contract, it is placed on a deemed contract.

E.ON fallback-rate summary

Situation	What E.ON calls it	What E.ON says
Fixed contract ends and you do nothing	Variable price plan / flexible contract	Prices are generally higher than on a fixed plan and can change at any time.
Fixed contract ends and you are leaving, but switch not yet complete	Out-of-contract prices	These are higher than the variable price plan until the switch completes.
You move in or take responsibility without agreeing a contract	Deemed contract	You are supplied under the deemed scheme and pay deemed prices.

E.ON deemed electricity rates

Meter type	Standing charge	Unit rate
NHH unrestricted	300.00p/day	36.5p to 41.1p/kWh
NHH Economy 7	300.00p/day	40.3p to 45.1p/kWh day / 27.7p to 33.8p/kWh night
NHH two-rate off-peak	300.00p/day	39.2p to 43.9p/kWh peak / 34.3p to 38.9p/kWh off-peak
NHH three-rate	300.00p/day	41.2p to 46.4p/kWh day / 29.0p to 32.6p/kWh night

These are E.ON Next’s published SME deemed electricity prices effective 10 April 2026, and they vary by distribution region. For unrestricted NHH electricity, the published regional unit rates run from 36.5p/kWh to 41.1p/kWh, with a flat 300p/day standing charge across all listed regions.

E.ON deemed gas rates

Meter type	Standing charge	Unit rate
Gas standard	175.00p/day	11.8p to 12.6p/kWh

E.ON Next’s published SME deemed gas prices effective 10 April 2026 show a flat 175p/day standing charge across the listed regions, with unit rates ranging from 11.8p/kWh to 12.6p/kWh depending on region.

E.ON deemed electricity rates by selected region

Region	NHH unrestricted	Economy 7 day	Economy 7 night	Gas standard
Eastern	36.8p/kWh	41.8p/kWh	27.7p/kWh	11.9p/kWh
London	37.5p/kWh	41.8p/kWh	29.6p/kWh	12.4p/kWh
Merseyside	39.6p/kWh	44.2p/kWh	31.2p/kWh	12.2p/kWh
North Western	41.1p/kWh	45.1p/kWh	33.8p/kWh	12.1p/kWh
Yorkshire	36.8p/kWh	41.0p/kWh	29.2p/kWh	12.6p/kWh

These are all taken directly from E.ON Next’s published regional deemed-rate cards for SMEs effective 10 April 2026.

Half-hourly deemed electricity

E.ON Next also publishes a separate HH deemed electricity card. Because those prices vary by region, voltage level and charging band, there is not one single HH deemed rate. For example, published unrestricted Non-Domestic Aggregated Band 1 HH unit rates run from 43.9p/kWh to 49.4p/kWh, while Band 4 runs from 34.2p/kWh to 38.5p/kWh depending on region. The daily standing charge also varies materially by band and region.

What the tables show

Key point	What it means
E.ON’s deemed prices are publicly available	You can benchmark current deemed electricity and gas pricing directly from E.ON Next’s published SME rate cards.
Variable and out-of-contract prices are described, but not laid out in one simple public SME rate card on the pages reviewed	E.ON Next explains when each applies and says out-of-contract prices are higher than variable prices, but the public pages reviewed do not show a single published SME table of those rates in the same way as the deemed cards.
Region matters	E.ON’s deemed electricity and gas prices vary by region, and HH electricity also varies by charging band and voltage level.

Which E.ON option is right for your business?

E.ON separates its business offer into two main routes. Smaller businesses that use up to 100,000 kWh of electricity a year or 293,000 kWh of gas a year can usually get quotes and manage tariffs through E.ON Next’s SME journey. Businesses above those usage levels, as well as firms with multiple sites, landlords, property managers and larger corporate users, are directed towards tailored contracts instead. 

Business type	Typical fit with E.ON
Small or medium business	Online quotes, fixed-price tariffs, online account tools
Multi-site business	Bespoke contract discussion
Landlord or property manager	Tailored business support
Large or corporate energy user	Bespoke large-business solution

Fuel mix and renewable electricity

For businesses with sustainability goals, it is worth understanding the difference between E.ON’s overall fuel mix and its renewable-backed tariff claims. E.ON says selected fixed tariffs for homes and small businesses are supplied with 100% renewables-backed electricity, but its published overall fuel mix for electricity supplied to residential, small business and corporate customers still includes gas, coal, nuclear and other sources because electricity is delivered through the National Grid. 

For the period 1 April 2024 to 31 March 2025, E.ON Next’s published fuel mix was 10.2% coal, 51.5% natural gas, 2.7% nuclear, 31.3% renewable and 4.3% other. E.ON also published an associated carbon intensity figure of 331 g/kWh for that period. 

Fuel source	E.ON Next fuel mix
Coal	10.2%
Natural gas	51.5%
Nuclear	2.7%
Renewable	31.3%
Other	4.3%
Carbon dioxide emissions	331 g/kWh

Sustainability credentials

Sustainability is an increasing priority for UK businesses, and E.ON has responded by incorporating renewable energy sourcing and carbon transparency into its electricity supply options.

E.ON customer service and reliability insights

For many businesses, supplier service quality is as important as price. E.ON has established infrastructure and support services geared toward business customers, from small enterprises to larger organisations.

EON Energy business tariffs

EON Energy offers a variety of tariffs to suit different business needs, whether you’re a small enterprise or a large corporation. Their tariffs fall into two main categories: fixed-rate and variable-rate options.

Fixed-rate tariffs

Fixed-rate tariffs are ideal for businesses that want to lock in their energy prices for a set period. This option protects your business from market fluctuations, providing predictable costs that make budgeting easier. With EON’s fixed-rate plans, you can typically secure prices for contracts lasting from one to three years.

Key benefits of fixed-rate tariffs:

• Price stability and protection from market increases
• Easier budgeting with predictable costs
• Suitable for businesses that prefer long-term planning

Variable-rate tariffs

Variable-rate tariffs fluctuate with market prices, meaning your rates could go up or down depending on wholesale energy costs. This type of tariff might be suitable for businesses that want to take advantage of potential decreases in energy prices but are also prepared for possible increases.

Key benefits of variable-rate tariffs:

• Flexibility to benefit from price drops
• No long-term commitment, making it easier to switch if needed
• Suitable for businesses that can handle price variability

EON Next – a customer-centric approach

EON has introduced EON Next, a new approach to managing energy accounts designed to provide a more personalised service. EON Next focuses on delivering a better customer experience with features like faster response times, dedicated energy specialists, and an emphasis on renewable energy.

Renewable energy focus

EON Energy is committed to sustainability, with all of its business electricity tariffs now backed by 100% renewable sources. This is a significant advantage for businesses looking to reduce their carbon footprint and meet corporate social responsibility goals. By choosing EON’s green energy tariffs, your business can demonstrate its commitment to environmental sustainability.

Specialised tariffs for SMEs and large businesses

EON Energy offers different plans tailored to the size of your business. Understanding which category your business falls into can help you choose the most cost-effective tariff.

Key features of EON Energy business tariffs

EON Energy’s business tariffs come with several features designed to offer flexibility, cost control, and sustainability.

Smart meters

EON provides smart meters to all its business customers, enabling more accurate billing and greater control over energy usage. These devices can help businesses monitor their consumption in real-time, identify areas where they can save energy, and reduce overall costs.

Energy efficiency advice

To help businesses reduce their energy usage, EON offers a range of energy efficiency services. These include consultations and advice on how to lower energy consumption, which can lead to significant cost savings and a smaller environmental impact.

Flexible payment options

EON Energy provides flexible payment options for businesses, including monthly and quarterly billing. Direct debit payments often come with additional discounts, making it a cost-effective choice for businesses looking to streamline their expenses.

Renewing your E.ON business contract

E.ON says eligible customers can renew online within 67 days of the contract end date. It also says businesses can call or email to renew up to one year ahead, and that tariff changes can be discussed within a 180-day window before the contract ends. 

If a fixed contract ends and no new deal is agreed, E.ON says the account moves onto a variable price plan. If the business ends supply and switches away without renewing, out-of-contract prices apply from the end of the fixed term until the new supplier switch is completed, and E.ON states that these prices are higher than its variable plan. 

Managing your account online

E.ON places a strong emphasis on self-service account management for business customers. Through the online account, businesses can view and download bills, submit meter readings, correct estimated bills, make card payments, manage Direct Debit details and update account information such as contact details and address information. 

For SME customers with compatible smart or AMR meters, E.ON also offers Optimum, a digital dashboard designed to help businesses understand electricity and gas use in more detail. E.ON says this tool can show energy consumption data, compare usage year on year for up to three years and provide tips to improve sustainability and reduce spend. 

Moving premises and setting up a new site

If you are moving out of a business property supplied by E.ON, the supplier asks businesses to get in touch with their moving date, new address and final meter reading so the old account can be closed correctly. If you are moving into a property already supplied by E.ON, the supplier can set up the new account once it has the business name, contact details and property information. 

E.ON also provides new electricity and gas connections for small to medium-sized commercial projects. Its business new-connections service is aimed at businesses that need a brand-new supply and meter set-up rather than a simple switch from an existing supplier. 

Pros and cons of EON Energy business tariffs

Here’s a quick overview of the pros and cons of choosing EON Energy for your business:

How to switch to EON Energy

Switching to EON Energy is a straightforward process. They handle the majority of the switching process on your behalf, ensuring minimal disruption to your business operations. The switch typically takes a few weeks to complete, during which you will receive regular updates on the progress.

How switching to E.ON works

E.ON offers 1, 2 and 3 year fixed business tariffs, with selected fixed tariffs including 100% renewables-backed electricity for eligible small business customers. The switch process is straightforward: get a quote, agree the tariff, then send opening meter readings once the switch is complete. E.ON also says businesses are supported by dedicated Energy Specialists during the process. 

In practical terms, most businesses will need their latest bill, recent meter readings and a clear view of annual consumption before requesting a quote. E.ON’s business contract guide also highlights unit rates, standing charges, contract length and fees as the key details to compare before signing.

Important considerations before switching

Before you switch to EON, it’s crucial to review your current contract terms and check for any exit fees. Also, compare their rates with other suppliers to ensure you’re getting the best deal for your business.
