Renovation grants in Brussels in 2026: what is still available?

If you search in 2026 for grants to make a Brussels home more energy efficient, you will still find plenty of articles about Renolution grants, complete with percentages, application deadlines and extra grants for heat pumps or energy audits. That information is out of date. At the moment, no Renolution grant is available for new works in the Brussels-Capital Region.

This article explains where things stand, where new information appears first and which rules do apply in the meantime: the PEB certificate (the Brussels energy performance certificate, called EPB in Dutch), the Brussels energy classes and the PEB 275 target that every home must meet by 2033 at the latest.

Renolution in 2026: what is the status of the grants?

The renolution.brussels website carries a clear notice: to date, the Brussels government has taken no decision on any possible new forms of financial support for renovation. As soon as more information is available, it will be published on the same website.

The Renolution grants page now only covers applications with a final invoice dated 2024, and that application period is closed. For works invoiced in 2025 or 2026 there is therefore no Renolution grant, and nothing has been decided on whether a possible new scheme would cover such works.

In practice, do not count on a Brussels regional grant in your 2026 budget. Percentages or amounts you still come across elsewhere for 2025 or 2026 have no official basis. No new scheme has been decided, so plan your works on your own financing and treat any future support as a bonus.

How to keep track

The most reliable source is the Renolution website itself, where news about any new support scheme will appear first. Bruxelles Environnement also refers homeowners to Homegrade for free guidance on improving their home. For an overview of all three regions, see our overview of renovation grants in Belgium.

The PEB certificate in Brussels: what is compulsory

Grants aside, the rules on the energy certificate remain fully in force. According to Bruxelles Environnement, the following applies.

• When a home of 18 m² or more is sold or let, a PEB certificate is compulsory. It must be drawn up before the property goes on the market.
• The listing must state the energy class and the energy performance in kWh/m²/year.
• You must give the valid certificate free of charge to anyone interested in your listing, and to the buyer or tenant.
• The certificate is drawn up by a PEB certifier approved by Bruxelles Environnement, after a site visit. You first receive a provisional version to check, then the official version.
• A certificate is valid for 10 years. An update is advisable after works, when you find new supporting documents or if the certificate dates from before 2017.

The price is not set by law. For information, Bruxelles Environnement gives average market prices: at least €210 including VAT for a 90 m² flat and at least €370 including VAT for a 200 m² house. Owners who do not comply risk a criminal penalty. If the public prosecutor does not prosecute, Bruxelles Environnement can impose an administrative fine of €50 to €62,500.

Today the certificate is only compulsory when a home is sold or let. Bruxelles Environnement has announced that every property will eventually need a valid certificate, at the earliest by the end of 2030. That date is not fixed yet, because it depends on new implementing orders whose entry into force has still to be set. For the application itself, see our article on requesting an energy performance certificate.

The Brussels energy classes

Brussels uses its own scale from A (most efficient) to G (least efficient), based on calculated primary energy use. This single scale covers the entire Brussels housing stock, houses and flats, old and new. It differs from the scales used in Flanders and Wallonia, so a class from another region cannot be compared directly. The thresholds below are the ones published by Bruxelles Environnement (Performance du bâti page, updated in December 2025).

Class	Primary energy (kWh/m²/year)
A	up to 45
B	46 to 95
C	96 to 150
D	151 to 210
E	211 to 275
F	276 to 345
G	more than 345

Within the classes there are sub-classes with a plus or minus. Bruxelles Environnement gives the example of a home at 148 kWh/m²/year: it is rated C. For what the letters mean in general, see our article on energy labels.

PEB 275 by 2033: what it means for you

Brussels has no renovation obligation tied to a purchase, unlike Flanders. It does have a target that applies to every home, whether you live in it, let it or have just bought it.

• By 1 January 2033 at the latest, every home must meet the PEB 275 target: primary energy use of no more than 275 kWh/m²/year. That currently corresponds to class E or better. A home in class F or G therefore does not meet the target.
• On 31 December 2045 at the earliest, the target will be lowered to 150 kWh/m²/year, currently class C or better. The government has yet to set that date.
• Homes owned by a public property operator must reach PEB 150 by 2040 at the latest.

Your PEB certificate tells you whether your home meets these targets and which works are recommended to reach them. If you do not have a certificate yet, that is the first step.

Planning works now, even without a grant

The lack of a grant does not change the 2033 target. With good preparation you will be ready, including if a new support scheme is introduced later.

1. Read your certificate. Note the class, the consumption in kWh/m²/year and the list of recommended works.
2. Gather supporting documents. A certifier can only take into account insulation or installations they can see or for which you have documents. The more technical evidence you provide, the better the result.
3. Keep all invoices and technical data sheets so that your certificate can be updated correctly after the works.
4. Follow renolution.brussels so that you know straight away whether a new scheme is coming and on what conditions.

What about Flanders and Wallonia?

The picture has changed there too in 2026. In Flanders, since 1 March 2026, owner-occupiers in the two highest income categories only receive a Mijn VerbouwPremie grant for a heat pump or a heat-pump water heater, with applications possible until 31 December 2027. For the lower income categories (3 and 4) the grant is unchanged. The Flemish Mijn EPC-labelpremie has been abolished: since 1 July 2026 it can only be claimed for files with an approved Fluvius activation dated 31 December 2024 at the latest.

In Wallonia, all applications for the current renovation grants (primes Habitation) must be filed by 30 September 2026 at 23:59, including the final invoice. From 1 October 2026 a new loan-based scheme applies (Rénopack and Rénoprêt). According to the Walloon government's press release of 16 July 2026, it targets label jumps: from G or F to at least D, or from E to at least C, with a compulsory audit beforehand. Details are on logement.wallonie.be.

Renovate, or sell the home as it is?

If you are weighing major works against selling your Brussels home, it helps to know first what it is worth on today's market. Request a free valuation and read whether you should renovate before selling. If you do sell, remember that the PEB certificate must exist before the listing goes live.
