Advance or Flat Fee: Utilities for Tenants in Austria

Service charges & settlements 2 min read · published September 10, 2025

What does Advance vs Flat Fee mean?

Advance payments are regular prepayments for expected utility costs that the landlord usually collects monthly and offsets against the actual annual statement. A flat fee is a fixed amount that covers all utilities and often does not include a detailed itemised breakdown at year end. For tenants the choice can affect monthly costs, refunds or additional charges.

Good records simplify later billing checks.

Pros and cons

  • Advance: More even monthly burden, but potential risk of additional charges.
  • Flat fee: Predictable fixed payment, but less transparency about actual costs.

How are bills calculated?

Landlords must make utility statements comprehensible and often present supporting documents; the legal basis is in the Mietrechtsgesetz (MRG).[1] Check the billing period, consumption values and allocation keys to detect errors or excessive claims.

Respond to statements within deadlines to avoid losing rights.
  • Collect documents: Keep invoices, meter readings and payment receipts.
  • Compare amounts: Do advance payments match the statement?
  • File an objection: Submit a written objection within the deadline if there are discrepancies.

FAQ

What can I do if the billing seems incorrect?
Request supporting documents, document your objections in writing and give the landlord a deadline to correct the issue; if there is a dispute, seek advice or court clarification.[2]
Can the landlord introduce a flat fee unilaterally?
A unilateral change is only permissible if the lease or legal rules allow it; otherwise a mutual agreement is needed.
When do additional charges or refunds occur?
Additional charges arise when actual costs exceed advances; refunds occur when prepayments were too high. Examine the statement carefully.

How-To

  1. Collect all relevant documents and proof of payments.
  2. Contact the landlord in writing with specific questions or objections.
  3. Submit any objections within the statutory deadlines.
  4. Seek legal advice or district court assistance if necessary.
