Rent revision (health index)

In Belgium, many residential leases provide for an annual rent revision indexed on the health index (health base 2013 = 100), published by the FPS Economy.

  • Automatic calculation of the revision from legal indices configured on the lease.
  • Notification when a revision is due on an active lease.
  • History and traceability per contract and per period.
  • Belgian health index (base 2013) — the most common case in Belgian residential renting.
  • Other statutory indices depending on lease configuration and applicable law.
  1. Create or import the lease with the indexation clause and revision date.
  2. Propria monitors due dates and calculates the proposed new rent.
  3. Approve the revision; future monthly payments reflect the updated amount.
  • Check the lease clause (index, effective date, any caps).
  • Keep notification documents in the tenant file.
  • If in doubt legally, consult Propria’s legislation library via the AI assistant or specialised advice.
