Always curious why other energy providers offer you free stuff when you sign up? The industry's dirty little secret is that they know they will find a way to make their money back from you — usually by making it really hard to end your contract, or by raising prices partway through.

This is why we believe that transparency is key. We offer you electricity at cost with a fixed monthly fee, no tiers or tricks (or "free" stuff).

Ostrom Referral Program

If you invite friends to Ostrom with your referral code, you'll receive a 50 € referral bonus added to your Ostrom account which will be displayed in the Wallet section in your Ostrom app. You can either have the amount deducted from your next invoice or you have the option to convert it into a 100 € credit for our store.

Referrer: To receive the referral bonus, your contract and the contract of the referred person must have been in delivery for at least two weeks.
​
​Referees: When you sign up using a referral code, you’ll get a bonus too. Stay with Ostrom for at least 11 months to receive your bonus in your wallet. Both you and the referrer need to have active contracts with us.
