We switched to Frank Energy when we bought home batteries. We were mainly looking for an energy supplier that innovates and supports technical solutions. Now we can get the maximum return from our energy contract. We use our batteries on the imbalance market, which earns us an average of €100 net per month. Frank Energy also lets us charge our car smartly. That means the car charges fully automatically when rates are lowest. Another 30% saving on charging costs. We look forward to new technical innovations and algorithms. Contact goes well when needed, and you quickly reach staff with the right knowledge. In short, we're happy with our switch to Frank Energy.

Frank is constantly responding to the changing energy market and offers customers flexibility, including through smart services such as Smart Charging and Smart Storage. If you, as an app user, look a bit more closely at your consumption and how to match it to dynamic prices, you can save a lot of money. The app is very much in development and improvements keep being made. What makes Frank unique is that, unlike some other spot price contract providers that offer "cheap batteries" for sale, they don't create vendor lock-in. As a customer you stay free to choose, at any time, without your home battery suddenly no longer being smartly controlled, for example. Customer service is easy to reach and quick to help, and the app gives clear overviews. As far as I'm concerned, a great example of how it should be done.

For me, Frank was the first with a dynamic energy price. We now want to buy a home battery to get even more benefit. It gives a lot of opportunities to save even more and to ease pressure on the grid. Charge in cheap hours, use in expensive hours.

Fast, clear and very promising, both in the contract and in the app.

The combination of Frank Energy and my home battery is not only worthwhile, but also a particularly interesting experiment that I haven't regretted so far. I appreciate that Frank Energie keeps moving along with all the new possibilities.

Besides supplying energy at market price, Frank Energy also offers extra services such as smart control of your electric car's charging or of a home battery. They take an open approach, meaning you're not required to have one specific brand of charger or home battery. You keep your freedom as a customer.

Clear app. Innovative energy supplier! My two Sessy home batteries are now happily trading on the imbalance market :-)
