Brussels rent grid 2026:
what every landlord should know.

What is the Brussels rent grid?

The indicative rent grid gives every Brussels home a reference rent: a price range calculated by the Region from more than 14,000 tenant surveys. It takes into account floor area, neighbourhood, the condition of the building (year of construction, double glazing) and features such as central heating, a second bathroom, a garage, storage and energy performance (EPC).

You can calculate it with the official simulator on loyers.brussels. The result is a range of ±10% around the median rent for a comparable home.

What changed in 2025 and 2026

• Since 1 May 2025, landlords may no longer propose an "abusive" rent. A rent is presumed abusive if it exceeds the reference rent by more than 20%, unless the landlord can justify specific comfort features. Conversely, a rent below that threshold can also be challenged if the home has significant quality defects.
• Under certain conditions, the tenant can ask for a rent review. Either party can refer the matter to the Joint Rental Committee (non-binding opinion) or to the justice of the peace.
• In January 2026, the reference rents were indexed to the change in the health index between August 2021 and December 2025. They are reviewed every year.
• The reference rent must be stated in every new residential lease in Brussels, alongside the actual rent.

Indexing your rent in 2026: the rules

Indexation of a Brussels lease is never automatic. Three conditions must all be met:

• the lease is registered;
• a valid EPC certificate has been given to the tenant;
• the landlord makes a written request.

Since January 2026, the health index has been published on a new base (2025 = 100). For homes rated EPC E, F or G, the Region applies a correction factor that reduces indexation: the less energy-efficient the home, the more limited the indexation. Always check the factor in force and the monthly index on the official websites (Statbel, be.brussels) before sending your request.

Landlords: rent or sell in 2026?

Between rent regulation, limited indexation for poorly rated homes and energy-renovation requirements that are gradually tightening in Brussels (the Renolution strategy), many owners are asking themselves the question. A few points to help you decide:

• Sale prices are high. According to the notaries' barometer, the average Brussels apartment sold for €301,666 and the average house for €609,227 in the first nine months of 2026. Read our 2026 market analysis →
• A de facto capped rent and reduced indexation lower the real return on an energy-inefficient home, especially with inflation close to 4.7%.
• EPC works ahead? If your property needs a major energy renovation, compare the cost of the works with the rent increase they would really allow, given the grid.
• Sell vacant or tenanted? A vacant property appeals to both investors and buyers who want to live in it, which is often where the price is highest. A tenanted property mainly appeals to investors, who think in terms of yield. The existing lease passes to the buyer.

Every situation is different: remaining lease term, condition of the property, your personal tax situation, plans to reinvest. A valuation of the sale price lets you compare both options concretely.

Frequently asked questions

Is the rent grid mandatory in Brussels?

The reference rent is indicative, but it must be stated in the lease. Since 1 May 2025, a rent more than 20% above the reference rent is presumed abusive, unless justified by specific comfort features.

Can you index a rent in Brussels in 2026?

Yes, if the lease is registered, an EPC certificate has been given to the tenant and the landlord requests it in writing. For homes rated EPC E, F or G, a correction factor reduces the indexation.

Is it better to rent out or sell a property in Brussels?

It depends on the real return of the property, the EPC works ahead and your plans. With high sale prices in 2026 and limited indexation for energy-inefficient homes, many owners compare both options based on a valuation of the sale price.
