🗓️ Estimated bills and back-billing in Slovenia: how far back can my supplier charge me?

The short answer

If your meter was not read for a long time, a large catch-up bill can follow. Many countries limit how far back a supplier may charge and set rules for meter readings.

📜 The rules in Slovenia

Back-billing and estimated bills

If your meter is read only once a year, you pay a monthly flat amount (pavšal) estimated from past use. To make the estimate more accurate, report your meter reading yourself during the year. Billing on actual use is only possible where smart metering is installed.

❓ Questions

Do I have to pay a huge catch-up bill at once?

Ask for a payment plan. Many suppliers must offer one; the rules for Slovenia are on this page.

Why did I get an estimated bill?

No reading was available. Send a real reading and ask for a corrected bill.

What if the meter was faulty?

Ask the grid operator to test it. Keep the test report for your complaint.
