**Thinking about switching to Ostrom? 🎉 Welcome – we’re excited to have you on board!**

How your switch is handled depends on **when** you signed up:

## 📅 Did you sign up before June 6, 2025?

Then the **old switching procedure** still applies:

- **Registration:**  
We’ll send your switch request to the grid operator and your current energy supplier. Sometimes you’ll get a reply within 30 minutes – but it can take up to **14 business days**.

- **Start of supply:**  
As soon as your cancellation period ends, the grid operator sends us your final meter reading – and Ostrom takes over your electricity supply.

## ⚡ Did you sign up after June 6, 2025?

Then you benefit from the new and fast **24-hour supplier switch**:

- **Fast & digital:**  
Your current supplier and the grid operator are legally required to respond to our registration request **within 24 hours**.

- **Earliest start: 24 hours after signup:**  
⚠️ Important: The start date of your supply must be **in the future** – and **at the earliest 24 hours** after you sign up. **Retroactive registrations are no longer possible.**

- **Recommendation:**  
Please sign up at least **14 days before your preferred start date** – that way, there's enough time for cancellations and a smooth handover.
