PEB A homes cost more: How much extra?

In Belgium, the energy performance of buildings (PEB) has increasingly influenced real estate values, a trend that has intensified amid the ongoing energy crisis. According to a recent analysis by L’Écho, the PEB rating significantly affects the sale price of properties, with energy efficiency becoming a pivotal factor for buyers.

The price impact of PEB ratings

An examination of housing sales over the past 12 months revealed that the energy performance level, as determined by the PEB certificate, has a considerable impact on property prices. This was quantified by isolating the effect of the PEB score on the prices of a standard reference property, consisting of a 95 sqm apartment or a 150 sqm house, and comparing it with similar properties, differing only in their PEB ratings. This methodology aimed to exclude other factors like the general condition or age of the building, which could also significantly influence property value.

The analysis showed that in Wallonia, a house with a PEB A rating (the highest possible energy performance) costs nearly 60,000 euros more than the same house with a PEB G rating! The difference is less pronounced for apartments, where buyers pay an additional 44,056 euros for a PEB A compared to a PEB G in the southern region.

Differences in Flanders and Brussels

The situation varies in the Brussels region, where only 1% of houses and apartments sold in the past 12 months had a PEB A or B rating. This discrepancy is attributed to Brussels’ stricter energy performance scale and the predominance of apartments in the city’s residential stock. However, L’Écho notes that a house with a PEB C in the capital sells for 25,921 euros more than the same property with a PEB G. For apartments, the price gap between a PEB B and a PEB G is 36,294 euros.

In Flanders, the price premium for a PEB A-rated house over one with a PEB F rating (PEB G does not exist in Flanders) is 69,241 euros. For apartments, the difference between PEB A and F ratings amounts to 49,551 euros.

What this means for buyers and sellers

For prospective buyers, understanding a property’s PEB rating is crucial, as it not only affects the purchase price but also future energy costs and environmental impact. Sellers with high PEB-rated properties can command higher prices, reflecting the increasing value that buyers place on energy efficiency.

Investing in energy efficiency

The significant price differences between high and low PEB-rated properties underscore the financial benefits of investing in energy-efficient improvements. Upgrading insulation, installing energy-efficient windows, and utilizing renewable energy sources are effective ways to enhance a property’s PEB rating, thereby increasing its market value and attractiveness to buyers.

Looking ahead: the role of PEB in real estate

As Belgium continues to focus on reducing energy consumption and greenhouse gas emissions, the importance of PEB ratings in the real estate market is set to grow. This trend aligns with broader environmental goals and reflects changing consumer priorities in the wake of the energy crisis.

For the real estate industry, adapting to these changes means prioritizing energy efficiency in both new constructions and renovations. For homeowners, it represents an opportunity to invest in their properties’ future, both financially and environmentally.


The correlation between PEB ratings and property values in Belgium highlights the economic and environmental advantages of energy-efficient homes. As the market evolves, both buyers and sellers will need to consider the implications of PEB ratings more carefully, making them a central factor in real estate transactions and investments.
