What is a Base Fee Discount (Grundpreisrabatt)?

A base fee discount is a bonus you may receive when signing up via partner or comparison portals.
It reduces your monthly deposit over a defined period.
💡 How does the base fee discount work?
- The discount is granted for 12 months from the start of supply
- It is automatically deducted monthly from your payment
- You don’t need to activate or apply for anything
- The discount is not reclaimed, even if your contract ends early
👉 This is not a one-time payout, but a monthly deduction.
📉 How is the discount paid out?
The base fee discount is directly deducted from your monthly deposit.
Example:
- Regular deposit: 90,00 €
- Base fee discount: 10,00 € per month
- Actual charge: 80,00 €
You’ll see this reflected in your billing.
❓ Why don’t I see the discount in my contract yet?
This is completely normal and the most common question.
Before supply starts:
- Your contract shows the deposit without the discount
- The reason: the discount is applied only once supply begins
👉 With your first debit after supply start, the discount is automatically deducted, even if it wasn’t visible before.
You will not miss out on the discount.
🧾 When does the discount apply?
- ✅ From the first payment after supply start
- ❌ Not before supply begins
Once your contract is active, the discount is applied automatically.
⛔ When does the base fee discount not apply?
The discount does not apply if:
- you were supplied by Ostrom
- at the same metering point
- within the last 6 months before signing up
🔄 What if I cancel before the 12 months are over?
No worries:
- Any discounts already granted remain valid
- There is no repayment
- No action needed from you
