About Ostrom

Ostrom gives you a choice most suppliers do not, and the two options are not equal: up to EUR 100 toward smart home devices, or EUR 50 off your next invoice.

Ostrom is a German energy supplier whose account and tariff live in an app, and which publishes in English as well as German — worth knowing if you are switching in Germany without fluent German.

Its referral programme runs on a referral code, and the reward shows up as a Reward in the Ostrom app once someone joins with it. What is unusual is the choice, and the fact that the two options are not equivalent: you can take up to EUR 100 off smart home devices in the Ostrom Store, or EUR 50 against your next energy invoice. The store credit is worth twice the bill credit, so the decision is really whether you want hardware or a smaller bill.

The headline amount has moved upward over time — an earlier version of the programme offered EUR 70 in store credit before it was raised to up to EUR 100 — so treat the figure as current rather than fixed.

Ostrom also runs periodic extras on top: referring at least one friend a month has entered customers into draws for items including a hoodie and a balcony solar power plant.
