Brussels reference rent grid: how to use it
The Brussels reference rent grid: how it works, calculating the reference rent, legal impact, and practical use for landlords and tenants.
How the reference grid works
The Brussels reference rent grid is a tool developed by the Rent Observatory of the Brussels-Capital Region. It provides a reference rent based on market data.
| Criterion considered | Impact |
|---|---|
| Location (municipality, neighbourhood) | Strong |
| Habitable floor area | Strong |
| Number of bedrooms | Medium |
| EPC score | Medium |
| Floor | Low |
| Parking available | Low-medium |
| General condition | Medium |
The grid is updated annually. It is indicative: the landlord is not obliged to follow it, but the tenant has a remedy if the rent is manifestly excessive.
Calculating the reference rent
Steps
- Go to the Brussels-Capital Region website
- Enter the address of the property
- Specify the floor area, number of bedrooms, EPC
- Obtain the reference rent (with min/max range)
Reference rent examples (2026)
| Property type | Municipality | EPC | Reference rent |
|---|---|---|---|
| 1-bed flat 50 m2 | Ixelles | C | 780-850 EUR |
| 2-bed flat 75 m2 | Schaerbeek | D | 850-950 EUR |
| 2-bed flat 80 m2 | Uccle | B | 1,000-1,150 EUR |
| Studio 30 m2 | Saint-Gilles | E | 550-650 EUR |
The EPC has a significant impact: a property rated B sits 10-15% above one rated E, for the same location and floor area.
Legal impact of the grid
The tenant’s remedy
| Condition | Possible action |
|---|---|
| Rent below grid + 20% | No remedy |
| Rent > grid + 20% | Application to the justice of the peace |
| Deadline to act | 2 months after conclusion of the lease |
| Sanction | The judge may reduce the rent |
Information obligation
The landlord must state in the lease:
- The rent of the previous lease
- The applicable reference grid
[!important] Legal point A landlord who fails to mention the previous rent in the lease may face an administrative fine. The tenant may request this information at any time.
Practical use of the grid
Use the grid as a starting point to set your rent. Stay within a +/- 10% range to avoid disputes. If your rent is higher, justify it by the condition of the property, fittings or recent works.
Create your lease online compliant with Brussels obligations and manage your properties with a rental management software.
