Customer Reviews
Good deal on gas and electric
I was looking for the best deal on stroom en gas and found Vattenfall had a good cashback offer for new customers. The overstapbonus made it worth switching from my previous provider. Took about 3 weeks for everything to process, but the savings are real. Felt like a smart move for my wallet.
Love my new contract!
Just signed up for a vast energiecontract with Vattenfall and I'm so glad I did! The online process was super quick and I even got a nice welcome bonus. Everything was explained really well. Definitely recommending them to my friends!
Easy setup, fair price
Signed up for stroom en gas. Website was easy to use. Price was competitive. No issues.
Smooth switch, decent app
I decided to switch to Vattenfall for stroom en gas after comparing a few providers. The online application for the vast energiecontract was very clear and easy to fill out. I got an email confirmation within an hour, which was nice. Delivery of the contract details to my email was quick. I also downloaded the Vattenfall Energie-app, and it's quite user-friendly for tracking usage. Customer support was helpful when I had a question about the termijnbedrag, they responded to my email in less than a day. The rates seemed fair, and the whole process was smoother than I expected. No complaints about quality of service so far.
Happy with the switch
So, I finally got around to changing my energy supplier and went with Vattenfall for stroom en gas. Heard good things from a friend. The online form was pretty simple, even for me, haha. It all went through without a hitch, and I got my confirmation emails pretty fast. It feels good knowing my energy is all sorted now. No drama, just easy.
Consistent service, reliable
Switched to Vattenfall for stroom en gas last year, and just renewed my vast energiecontract. Always pretty straightforward to manage everything online. This time, the renewal bonus wasn't quite as good as my first welkomstcadeau, but the service has been consistently reliable. No surprises, which is what I want from an energy provider.
