Keypilot automates rent indexation with the current Belgian health index. Calculate the correct indexation per region, generate indexation letters and send them directly to your tenant.
The base formula (base rent × new health index divided by the starting index) applies throughout Belgium, but each region has known its own temporary corrections and rules.
In Flanders you index the rent annually on the lease anniversary using the health index. During the energy crisis, temporary limits applied in 2022-2023 for properties with a poor EPC label.
Keypilot knows the correct formula per period, warns you before every anniversary and keeps the full indexation history per lease.
In Wallonia you also index annually with the health index. The Walloon decree had its own temporary corrections based on the PEB label in 2022-2023, and lease registration is mandatory.
Keypilot applies the Walloon rules automatically and reminds you about registration, so your indexation is never at risk.
In the Brussels Capital Region, temporary EPC limits also applied in 2022-2023. Today you index again under the ordinary health index, provided the tenant receives a correct written notification.
Keypilot generates the indexation letter in Dutch or French and applies the Brussels rules per period.
Some tools only recalculate indexation, others integrate it fully into your lease and payment management. Here is how Keypilot compares to Omnicasa, Rentio and solved.immo.

Annually on the lease anniversary: base rent × (new health index / starting index). Keypilot does this automatically.
A derivative of the consumer price index published by Statbel, the official index for Belgian rent indexation.
No, it's a landlord right. You must notify your tenant in writing. Keypilot generates the letters.
For poor-EPC properties, Flanders and Brussels had temporary limits. Keypilot tracks regional rules.
You may index the rent at most once a year, on the anniversary of the lease's entry into force. The indexation only takes effect from the written notification to the tenant. Keypilot tracks every anniversary automatically.
Registration of leases for a primary residence is mandatory in all three regions. Without registration you risk not being able to claim the indexation. Keypilot reminds you in time to register every lease.
In practice, indexation can only be reclaimed retroactively to a limited extent, so indexing late means permanently losing rental income. Keypilot watches every anniversary and warns you in advance, so you never miss an indexation year again.
The temporary EPC limits of 2022-2023 in Flanders, Wallonia and Brussels have ended. The ordinary health index applies again. Keypilot tracks regional rules per period, including any future changes.
