Works and temporary rent reduction in Belgium
Temporary rent reduction during works in a rental property in Belgium. Conditions, calculation, procedure and tenant rights.
Principle of the rent reduction
The Belgian Civil Code (art. 1724) provides that the tenant must tolerate urgent repairs, even if they cause inconvenience. In return, if the works last more than 40 days or significantly reduce the enjoyment of the dwelling, the tenant may request a rent reduction.
When the reduction applies
| Situation | Reduction possible |
|---|---|
| Room inaccessible during works | Yes |
| No hot water or heating | Yes |
| Excessive noise during rest hours | Yes |
| Short works (< 40 days) without loss of enjoyment | No |
| Works in common areas (co-ownership) | Depends on impact |
For general rules, see our guide on rights and obligations.
Calculating the reduction
Proportional method
The reduction is calculated in proportion to the loss of enjoyment:
| Loss of enjoyment | Indicative reduction |
|---|---|
| 1 room out of 4 inaccessible | 20-25% |
| No heating | 30-40% |
| No hot water | 15-20% |
| Dwelling totally uninhabitable | 100% (rent suspension) |
| Significant noise nuisance | 10-20% |
Duration of the reduction
The reduction applies for the entire duration of the works, from the moment the inconvenience is established until complete restoration.
Agreement or judicial decision
| Method | Advantage | Disadvantage |
|---|---|---|
| Amicable agreement | Quick, free | Not always balanced |
| Mediation | Balanced, low cost | Delay (1-2 months) |
| Justice of the peace | Binding decision | Delay (2-4 months) + costs |
Procedure
Step 1: document the inconvenience
- Take photos of the works and their impact
- Note the start and end dates
- Assess the loss of enjoyment (inaccessible rooms, services cut off)
- Keep the landlord’s letters announcing the works
Step 2: request the reduction
Send a registered letter to the landlord:
- Describe the inconvenience suffered
- Propose a proportional reduction amount
- Set a response deadline (15 days)
- Attach evidence (photos, works schedule)
Step 3: in case of disagreement
If the landlord refuses the reduction:
- Propose mediation (free via the justice of the peace)
- If unsuccessful, refer to the justice of the peace
- Continue paying the full rent while awaiting the decision
The tenant may not reduce the rent on their own initiative. Only a written agreement with the landlord or a decision by the justice of the peace authorises the reduction.
Limits and exceptions
Works the tenant must tolerate
- Urgent repairs (even if inconvenient)
- Works necessary for the preservation of the property
- Works imposed by an administrative decision
Works the tenant may refuse
- Non-urgent improvement works without consent
- Works altering the nature of the dwelling
- Works of excessive duration without compensation
Lease termination
If the works last more than 40 days and render the dwelling uninhabitable, the tenant may request lease termination without compensation.
