Property certifications by region — Brussels, Wallonia, Flanders
Key facts
Belgium's three regions share the same baseline (PEB required at sale/rental, RGIE for electrical, asbestos banned since 1998), but with separate regulators and timelines: Bruxelles Environnement in Brussels (PEB since 2011, fines up to €62,500), SPW Énergie in Wallonia (PEB since 2010), VEKA in Flanders (EPC since 2008) — the asbestos inventory is required at sale in Flanders via OVAM, and before works in Brussels via Bruxelles Environnement.

- EPCEPC
- Energieprestatiecertificaat. Flemish name for the energy certificate, managed by VEKA. Required in Flanders since 2008.
- RGIERGIE
- French-language name of the Belgian federal electrical installation rules. Managed at federal level by SPF Économie, with a distinction between installations before and after 1 October 1981.

- A++ -> G scale
- Energy score of the PEB or EPC certificate. A++ means theoretical consumption below 45 kWh/m²/year, while G is above 345 kWh/m²/year. The score must appear in sale and rental listings.
- kWh/m²/year
- Standard theoretical consumption unit used by the energy certificate: kilowatt-hours per heated square metre over a typical year.
- 30 mA / 300 mA residual-current device
- Protection devices required by the federal electrical rules. The 30 mA device protects wet rooms; the 300 mA device protects the general installation against insulation faults.
- Sale agreement
- Private agreement between seller and buyer before the notarial deed. The PEB or EPC certificate must be presented no later than signature.
- Notarial deed
- Authentic deed transferring ownership. The notary may block signing when the required energy certificate or inspection report is missing.
- Fibre cement
- Historic material combining cement and asbestos fibres, used in Belgium until 1998. Common in roofs, pipes and cladding on older buildings.
