Comparison of minimum scores by region
All three Belgian regions have adopted similar approaches but with different timelines. The principle is the same everywhere: progressively ban the letting of the most energy-hungry dwellings.
| Deadline | Brussels | Wallonia | Flanders |
|---|---|---|---|
| 2025 | G banned | G (>600 kWh) banned | - |
| 2028 | F banned | - | F banned |
| 2030 | - | F banned | - |
| 2033 | E banned | - | - |
| 2035 | - | E banned | E banned |
| 2036 | D banned | - | - |
Brussels is ahead of the other two regions. A landlord owning properties in several regions must follow each region’s deadlines separately. The EPC certificate is the reference document.
Brussels: the strictest timeline
| Year | Minimum score | Indexation |
|---|---|---|
| 2025 | F minimum | E: 50 %, F-G: 0 % |
| 2028 | E minimum | D+: 100 %, E: 50 % |
| 2033 | D minimum | To follow |
| 2036 | C minimum | To follow |
Indexation is also conditional on the EPC score since November 2022. An F or G-rated property can no longer be indexed at all, and an E-rated property can only be indexed at 50 %.

Wallonia: progressive timeline
| Year | Threshold kWh/sqm per year | Equivalent label |
|---|---|---|
| 2025 | > 600 banned | G+ banned |
| 2030 | > 450 banned | F banned |
| 2035 | > 350 banned | E banned |
| 2040 | > 250 banned | D banned |
In Wallonia, indexation for F and G-rated properties is also frozen. Habitation grants cover part of the energy renovation costs.

Flanders: EPC label
| Year | Minimum label | Associated measure |
|---|---|---|
| 2023 | EPC label mandatory | Display in every listing |
| 2028 | E minimum (F banned) | Obligation at reletting |
| 2035 | D minimum (E banned) | Progressive tightening |
Flanders also links the EPC label to indexation. The Mijn VerbouwPremie programme offers grants for energy renovation.

How to anticipate the deadlines
Regardless of where your property is located, the strategy is the same:
- Check your EPC certificate. If it does not exist or is expired, have it issued by a certified assessor.
- Identify priority works. Roof insulation and glazing replacement offer the best cost-to-improvement ratio.
- Apply for regional grants. Each region offers substantial aids (Renolution in Brussels, Habitation in Wallonia, Mijn VerbouwPremie in Flanders).
- Plan long-term. Deadlines are approaching. Better to invest progressively than to do everything in a rush.
A rental management software centralises the EPC certificates of all your properties and alerts you to upcoming deadlines.
