Complaint report data - information and figures about our complaints

We work hard to stop things going wrong so you don’t have to get in touch with us. But we know we’re not perfect, so if something’s not right, it's important we fix it as soon as we can.

Ofgem, our industry regulator, says we must:

  • Publish our complaints procedure and make the process for handling complaints clear and straight forward
  • Follow our process every time:
  • Make sure you know what the process is, and where you are in it, from the time you first make a complaint to when we resolve it.

Complaints reporting in October to December 2017

The number of complaints we received

The number of complaints has increased by 4,233 from 156,736 in quarter 3 of 2017 to 160,969 in quarter 4. This is 43,697 complaints higher than in the same quarter of 2016 when we received 117,272 complaints.

Long call waits were still causing higher volumes of complaints in quarter 4. We continued to work on service stabilisation and this resulted in wait times improving across the quarter to within 2 minutes in December. We expect to see this will feed through to a reduced number of complaints on this topic in Q1 2018.

Complaints we were able to fix before the end of the next working day and within eight weeks

The percentage of complaints resolved by the end of the next working day has slightly decreased since last quarter from 70.88% to 69.17%. There has however been a slight increase in the percentage of complaints we resolve within 8 weeks against the last quarter from  93.43% to 93.74%. We’re committed to do whatever we can to resolve complaints as quickly as possible. We aim to make sure that we fully fix the issue once and for all, to prevent our customers having to complain about the same problem again.


What should I do if I want to complain to E.ON?

We have a clear process for handling complaints. The first step is to contact us and let us know you’re dissatisfied. It’s important that you let us know about what’s gone wrong so we have a chance to fix it for you.

For more information on how we manage complaints and what you can expect from us when you have a complaint, read our complaints handling procedure.

What are we doing to improve complaints?

Putting customer service at the heart of what we do

We're continuing to focus on the training and coaching of our advisors, to successfully set them up with the skills and knowledge they need to deliver a fantastic customer service. This has included refreshing the knowledge needed to deal with customer complaints.

We’re working hard to make it as easy as possible for customers to contact us on the telephone when they need to. We’ve also increased the size of our live chat team, to make it easier for customers to get in touch.

Bills and letters

We’ve recently completed the roll out of a new knowledge tool in our billing customer contact centres, which supports our advisors in having great conversations when resolving complaints.


Agreeing affordable and sustainable payment arrangements with customers continues to be a key focus.   

We offer a wide range of payment options, including Direct Debit and prepayment so that customers, where possible, pay in whatever way is easiest for them. Advisors are trained on how to offer fair payment arrangements to customers who can't afford to pay. If anyone is having difficulty making payments, we advise them to get in touch as soon as possible so we can help. 

The E.ON Energy Fund can help vulnerable people by providing assistance of energy bill arrears as well as the purchasing and replacement of white goods or gas boilers. You can also apply for a number of online courses to support you in managing your finances, staying out of debt, earn a qualification and if needed getting back into work. Applicants do not need to be supplied by E.ON, but they do need to meet eligibility criteria to apply. 

You can apply either online at or by calling 03303 80 10 90, where you can request that we send you a form by post or apply directly over the phone.
