E.ON Business plans and prices

E.ON Business offers a range of plans to suit your individual business’ needs. The company’s electricity and gas plans are sold separately. If you’re not already an E.ON Business customer, it will take around six weeks to switch to the company from your current energy supplier.

Since E.ON Business customizes your price based on the size of the business and its projected energy use, you should use your own gas and electricity consumption levels in order to get an accurate quote. You can find this information on any bill or renewal letter from your current provider.

Not sure how much energy your business uses? Refer to the table below to get an idea of how much it consumes.

Business Sizes and Consumptions

SME plans

E.ON Business plans for SMEs are available for customers that use either less than 1 GWh of energy per year or spend less than £175,000 on their annual gas and electricity bills. The company now offers 100% renewable electricity to these customers as standard.

E.ON Business offers fixed-rate plans (in which the rate is guaranteed for the duration of the agreement) that last from one to three years. While the longer-lasting plans currently include more expensive rates than shorter plans, you will likely save more money over time because the price is protected from any sort of increase for a longer period of time.

The company also provides variable plans (in which the rates are not guaranteed, but rather fluctuate with the wholesale cost of energy). Variable rates are almost always more expensive than fixed rates.

Customers are automatically placed on a variable plan when their fixed contract comes to an end. The one benefit that variable plans offer is that you only need to give thirty days notice to switch to a different supplier. With fixed plans, you must wait until the agreement ends before you are able to change companies.

Large business energy contracts

Industrial and commercial businesses that spend more than £175,000 on energy or use more than 1GWh of gas or electricity a year must contact the sales team for a quote by calling 0333 202 4654.

In addition to providing gas and electricity, E.ON Business also provides services to help large businesses with changes in market prices, as well as to give advice on how your business can be more sustainable.

Before you switch to E.ON Business

Once you agree to a business energy contract, you will not be able to switch to a different offer until the contract ends. This is why it’s so critical to get it right the first time around.
