📈 My energy supplier is raising prices in Slovakia. What can I do?

The short answer

A supplier cannot raise your price overnight. It has to warn you in advance, and that notice often gives you the right to leave.

📜 The rules in Slovakia

Price rises

Your supplier must announce any price or terms change at least 30 days before it applies (publication on its website is enough). If you disagree, you can terminate free of charge by notifying it at least 15 days before the change.

Switching supplier

Switching is free: suppliers may not charge for it. It takes at least 21 days, usually to the 1st of a month; the new supplier can handle it with your power of attorney. Regulated-price contracts: open-ended with 2 months' notice, or 12 months; for market-price contracts the lock-in is set in the contract.

❓ Questions

Can a fixed price be raised?

Normally not during the fixed period, unless your contract says so. Taxes and levies can still change.

Do I pay an exit fee if I leave after a price rise?

In many countries you can leave without a fee when the price goes up. The rules for Slovakia are on this page.

What if I missed the letter?

Ask the supplier for a copy and the date it was sent. If they cannot show proper notice, complain.
