“Excellent experience! Everything was great, and I am very satisfied with the service. Highly recommended!”

perfect service , and fast

E.on very poor system of organization firstly they mess my contract up gave me wrong reference numbers make me to paid 172€ with wrong reference number also made me again paid 164+170=334 so they can not be trusted and they seem to make stupid and wrong thing i regret registering my light with this company so far it very bad.

Excellent customer service and product was shipped one day ahead of time.

Not very expat friendly. Hard to reach customer support, and I have issues with their Check24.de integration.
Overall happy with the prices, it is ok.

Changed monthly payment but it was never followed. But getting contract was easy.

Edit: I contacted the email mentioned in the reply to review. The person promptly resolved issue but did not give any reason or response for why it happened in first place. Overall quick service. So changing from two stars to 4 stars

I think this company’s app is a major advantage. Using it allows you to effectively monitor and control your electricity consumption, as you can track your usage and estimate your final bill. Customer 2025

Good and helpful

„Great support, going far above and beyond. Took a lot of time and also involved other departments.“

Nice everything

£400 paid only after legal action and an Ombudsman finding
Date of experience: 19 February 2026
I am extremely disappointed with the way E.ON handled my complaint.
I had opted out of direct marketing but subsequently received two telephone calls from E.ON's outsourced partner, Firstsource, regarding my E.ON tariff.
I raised my concerns with E.ON and requested information about how my personal data had been processed. When I remained dissatisfied, I escalated the matter to senior management, including E.ON's UK leadership and the German Board. My correspondence specifically explained my concerns about the processing of my personal data.
E.ON's own Escalated Complaints Team acknowledged that I had written to the German Board and told me that they were there to "own and resolve" my complaint. However, despite this escalation, I was subsequently told that E.ON would not respond to further contact and would wait for the ICO and Energy Ombudsman processes.
E.ON's eventual Deadlock Letter stated:
"there hasn't been any data breach and that we have acted in line with our T&C's and Privacy Policy."

I did not agree with that position and ultimately had to take the matter further. Following my Letter Before Claim, E.ON's legal team agreed a £200 settlement relating to the direct-marketing/data-protection concerns.
However, I also separately pursued E.ON's customer service and complaint handling through the Energy Ombudsman.
The Ombudsman upheld my complaint and found that E.ON's handling involved:
- initial delays;
- factual inconsistencies;
- reactive communication;
- incorrect initial information about the telephone calls;
- unnecessary time, trouble and inconvenience; and
- a complaint process that became unnecessarily prolonged.
The Ombudsman specifically found that E.ON's £75 customer-service offer was inadequate and awarded me a further £200 for the customer-service failures, together with an apology.
Therefore, E.ON ultimately paid £400 in total, relating to two separate aspects of the dispute:
£200 – following legal correspondence concerning the direct-marketing/data-protection issue.
£200 – following the Energy Ombudsman's finding that E.ON's customer service and complaint handling had fallen below a reasonable standard.
The Ombudsman's decision expressly states that the second £200 was for the customer-service and complaint-handling failures only and did not duplicate the separate data-protection settlement.
What disappoints me most is that I had already escalated my concerns to senior E.ON management, including the German Board, before taking legal action. E.ON knew I was raising serious concerns and its own escalated complaints handler acknowledged the impact the matter was having on me. Yet I still had to pursue legal action and ultimately involve the Energy Ombudsman before the matter was properly resolved.
I am pleased that an independent Ombudsman ultimately recognised the service failures, but I believe this should have been resolved much earlier without a customer having to spend months chasing, escalating and taking formal action.
This experience has seriously damaged my confidence in E.ON's approach to customer complaints and how it deals with customers when things go wrong.

Easy super!👍
