Offers a broad range of tariff types
Rarely the cheapest option
E.ON supplies around 3.8 million UK homes and businesses. A subsidiary of German energy giant E.ON SE, in 2019 it bought out rival “Big Six” supplier Npower. That same year it committed to providing all household electricity customers with power from 100% renewable sources, and now owns wind farms, biomass plants and a tidal power generator, and says it aims to increase its production of green energy.

E.ON customer reviews

Data collected by the charity Citizens Advice isn’t particularly encouraging. It shows that in 2020 for every 10,000 customers E.ON supplied, it received 29.2 complaints that were escalated to a third party, including to the Energy Ombudsman – a dispute resolution organisation recognised by the energy industry. This was below average in terms of performance across the industry for 2020.

Reviews on the website Trustpilot suggest customers are broadly satisfied, if not ecstatic, with the service they receive from E.ON. Out of just over 30,000 customer reviews posted to the site, 48% of posts give E.ON a rating of “excellent” while 29% give the firm a “bad” customer service rating (last updated: August 2021).

Pros and cons of E.ON

Pros

  • E.ON generates its own low carbon electricity. E.ON commits to supplying its household, and some business customers, with electricity from 100% renewable sources. This can come from E.ON’s own generation facilities or matched through regulator Ofgem’s Renewable Energy Guarantees of Origin (REGO) scheme.
  • A broad range of tariff types. As a “Big Six” supplier, E.ON offers a wide range of fixed, variable and dual fuel tariffs.

Cons

  • Mixed customer service. E.ON’s complaints scores and response times were below average for the industry in 2020, according to data gathered by Citizens Advice. Customers have similarly mixed reviews of their experiences with the firm.
  • Rarely the cheapest option. Like most of the larger suppliers, it’s rare that E.ON tariffs provide the cheapest unit pricing or standing charges for energy usage.

Our verdict: Is E.ON any good?

As one of the larger UK energy suppliers, E.ON is well placed to offer a range of products and services to household energy customers, including smart meter installation. For environmentally conscious consumers looking for a big name supplier, E.ON could be worth a look, given its relatively recent commitment to provide electricity from 100% renewable sources to all its household customers.

It’s worth noting that, like most “Big Six” energy suppliers, E.ON is rarely going to offer the lowest prices for household usage. So if low prices are your main priority, E.ON may not be at the top of your list.
