Rent indexation in Anderlecht
Rent indexation in Anderlecht
Rent indexation in Anderlecht: Brussels rules, EPB median E impact, calculation and practical examples.
Rent indexation in Anderlecht in 2026
Anderlecht has a median EPB of E, meaning most leases in the commune face the Brussels indexation restriction. Since October 2022, E-rated properties can only index at 50% of the health index, and F or G-rated properties — still common in Anderlecht’s older stock — lose this right entirely.
On an average rent of 875 EUR/month (2-bedroom in Anderlecht), an E-rated property only recovers approximately 10 EUR/month of indexation instead of 21 EUR at full rate. This shortfall of 132 EUR/year weighs all the more because Anderlecht rents are already among the lowest in the Brussels Region, with tighter yield margins.
Indexation rules in the Brussels Region
- Formula: base rent x (new health index / health index of the month preceding lease signature)
- EPB thresholds: classes A to D = 100%, class E = 50%, classes F-G = 0%
- Anderlecht impact: median EPB E, most leases face reduced indexation — older stock often rated F
- Low rents: with an average rent below the regional level, the relative impact of EPB restrictions is proportionally heavier
- Notification: mandatory written request, at the earliest on the lease anniversary
- Retroactivity: limited to 3 months after the anniversary date
Practical advice for Anderlecht
In Anderlecht, the economic calculation for energy renovation deserves careful attention. Moving from E to D doubles the indexation, but the commune’s low rents (875 EUR average) generate a modest annual gain (approximately 130 EUR). It is therefore essential to assess whether works are justified by other levers: base rent revaluation, vacancy reduction, access to Renolution grants. In the meantime, landlords must ensure every lease has a valid EPB and send the indexation request on time — even at 50%, cumulating this revaluation over the lease term remains a meaningful lever.
