Customer Reviews
Satisfied with Wärmepumpenstrom
Signed up for Wärmepumpenstrom. Application was simple. Prices seemed fair. Took a few days for everything to go through. So far, no issues with service. Happy with my choice.
Easy switch, great bonus!
I just switched to E.ON for my natural gas, and it was so easy! I got the Neukundenbonus, and it really made a difference in my first bill. The whole process online was super quick, and I got my confirmation fast. I'm telling all my friends about it, definitely recommend E.ON for gas!
Good service, small hiccup
I switched our household electricity to E.ON's Ökostrom tariff last month. The online application was straightforward, and I liked the transparency of the pricing. The initial confirmation email took about 24 hours to arrive, which felt a little slow, but everything else was smooth. The customer service I spoke with to confirm my start date was helpful and answered all my questions clearly. I appreciated the quick setup once everything was processed. Overall, a positive experience, though a faster initial email confirmation would be a nice touch.

Anyone know if E.ON is actually good for solar stuff? My buddy was looking at Vattenfall but I heard E.ON has some decent options for PV and batteries.
hey, was thinking about switching to E.ON for my electricity. do they ever have good deals for new customers, like a bonus or something?
