Besides sending an email to Eon, you can also submit an online form on the company’s website. To access the form, go to the Eon homepage and click on Account and help in the top bar. Scroll down to where it says You can email us, too in red letters on the left-hand side. Then click on the link to the right that says online form.

Eon live chat

The quickest way to speak with a customer service representative is via the Eon live chat. We received a response using this online service in less than a minute!

To access the Eon live chat, go to the supplier’s homepage and click on where it says Account and help in the top bar. Scroll down until you see a blue box on the right-hand side that says Live chat. Click on the white button that says Chat now.

You will need to enter the following details in order to begin using the Eon live chat:

  • Your first name
  • Your last name
  • Your email address
  • Your account number (optional)
  • The subject related to your query (selected from a drop-down list)

In addition to the Eon live chat, customers can also reach out to Eon via Facebook Messenger. However, since it took Eon customer service nearly a day to respond to our message on Facebook, we recommend using the Eon live chat in order to get a much swifter response.

Customer service review: Is it any good?

Now that you know how to get in touch with the Eon customer service department, let’s take a look at how effective it actually is and how it compares to customer service departments from other energy suppliers across the UK.

Eon customer service is ranked number 18 out of 41 energy suppliers, according to the latest research from Citizens Advice. The organisation compares UK energy suppliers on a quarterly basis across the following six categories:

  • Average call-wait time
  • Number of complaints per 10,000 customers
  • Customers who had an accurate bill in the past year
  • Bills and statements sent on time
  • Switches completed within 21 days
  • Customer guarantees

Out of the so-called Big Six energy suppliers, Eon customer service came in at a disappointing fifth place, just in front of Scottish Power in last place. The following table breaks down the customer service ratings for Britain’s traditional Big Six companies:

Northern Powergrid contact phone numbers
Rank Big Six supplier Customer service rating (out of 5)
1 SSE 3.85
2 EDF Energy 3.7
3 Npower 3.6
4 British Gas 3.6
5 Eon 3.15
6 Scottish Power 3.1

Eon’s lowest-scoring categories were its call-wait time and number of complaints, for which it received just two out of five stars for both. As we stated before, we waited for around 15 minutes before we were able to get through to an Eon customer service agent. With regards to its high number of complaints, Eon received 31.7 complaints per 10,000 customers during the first quarter of 2020.
