In Belgium

The rent grid is a reference tool developed by the Regions. In Brussels, it calculates a rent range based on property characteristics: surface area, rooms, floor, year built, EPC label, garden/parking, and location. The housing ordinance requires landlords to mention the grid range in letting advertisements.

In Wallonia, a similar grid exists. In Flanders, no official grid but estimation tools are available.

The landlord remains free to set rent outside this range. The grid is indicative, not binding.

Good to know
The indicative grid is not a cap. The landlord can charge more if the property’s characteristics justify it (premium finishes, exceptional location).

Practical example

Catherine lets a 2-bedroom apartment of 85 m2 in Saint-Gilles (Brussels), EPC C, 3rd floor with balcony. The indicative grid shows a range of 880 to 1,080 EUR/month. Catherine sets rent at 980 EUR and mentions in her ad: “Rent: 980 EUR — Indicative grid: 880-1,080 EUR”.

Key considerations

Warning
The grid does not account for furniture in furnished rentals. A furniture supplement can justify a rent above the indicative range.
