Cost of an EPC Certificate After Renovation Works in Belgium

The cost of an EPC certificate after renovation works in Belgium generally ranges between 150 and 400 euros, depending on the region, the size of the property and the approved certifier you choose. If you have carried out insulation work, replaced your heating system or installed solar panels, obtaining a new EPC certificate is often essential before putting your property on the market. This document reflects the actual energy performance of your home and directly influences its value on the market.

Why get a new EPC certificate after a renovation?

An EPC certificate (Energy Performance of Buildings) is valid for ten years. But if you have carried out significant works, the old certificate no longer reflects the reality of your property. A home that has moved from class E to class B or C is worth noticeably more on the Belgian property market.

In Wallonia, Brussels and Flanders, the regulations require a valid EPC certificate to be presented at the time of any sale or rental. An expired or inaccurate certificate can lead to administrative penalties and slow down the transaction. It is therefore better to sort this out before contacting an estate agent.

In 2026, buyers are paying increasing attention to energy labels. According to Belgian property market data, a property rated A or B sells on average 10 to 15% more than an equivalent property rated D or E. Getting a new EPC after renovation is a concrete way of realising the value of your investment.

What are the going rates in Belgium in 2026?

Prices are not uniformly regulated. Each approved certifier sets their own fees freely. Here are the ranges observed by region:

• Wallonia: between 150 and 300 euros for an apartment, between 200 and 400 euros for a single-family house.
• Brussels-Capital Region: between 180 and 350 euros, with rates sometimes higher in the city centre due to urban density and the more complex nature of the properties to be assessed.
• Flanders: between 150 and 320 euros, depending on the size and type of property.

These amounts include the on-site visit, the collection of technical data, the entry into the regional database and the issue of the official certificate. Some certifiers offer packages that include additional renovation advice, which can justify a slightly higher rate.

For large properties or multi-apartment buildings, the cost can exceed 500 euros. In that case, it is worth requesting several quotes.

How do you choose an approved certifier?

Only certifiers recognised by their region can issue a valid EPC. In Wallonia, the list is managed by the Service Public de Wallonie (SPW). In Flanders, it is VEKA (Vlaams Energie- en Klimaatagentschap). In Brussels, it is Bruxelles Environnement (IBGE).

To find a certifier, you can consult the official online databases for each region. It is advisable to request at least two quotes before making your decision. Check that the professional's accreditation is current and that they have experience with the type of property you own.

Your estate agent can also point you towards reliable certifiers in your area. If you do not yet have an agent, you can compare IPI-approved estate agents free of charge on ImmoMakelaarVergelijker to get local recommendations.

How long does it take to get the certificate?

In practice, the time between first contact and receipt of the certificate is five to fifteen working days. It all depends on the certifier's availability and the complexity of the file.

To speed up the process, prepare the following documents before the visit:

• Invoices for the works carried out (roof, wall and floor insulation).
• Technical data sheets for the insulation materials installed.
• Documentation for the heating system installed (boiler, heat pump, pellet stove).
• Certificates for photovoltaic or solar thermal panels, where applicable.
• The planning permit if any structural alterations were made.

The more complete your file, the more accurately the certifier can enter your data. This can make the difference between a class C and a class B rating, which has a direct impact on the sale price of your property.

EPC and resale value: what it actually changes

An improved EPC rating is not just an administrative formality. It is a tangible selling point. In Belgium, buyers are increasingly factoring in future energy costs when making their purchasing decision. A better-insulated property means lower monthly running costs, which makes the offer more attractive.

Furthermore, since 2023 in Flanders - and progressively in the other regions - energy renovation obligations apply to new owners within a set period after purchase. A property that already has a good rating spares the buyer these constraints, which can ease negotiations and reduce room for price discussions.

To maximise the value of your property after renovation, it is worth working with an estate agent who knows the local market well and can highlight your energy rating in the listing and during viewings. You can compare local estate agents via IMV right now and receive up to three free, no-obligation proposals.

Summary: the key takeaways

Getting a new EPC certificate after renovation works costs on average between 150 and 400 euros in Belgium. This amount is largely offset by the potential increase in sale price. The process generally takes one to two weeks and requires a few technical documents related to the works carried out. Choose an approved certifier in your region and do not hesitate to compare rates.

Before putting your property on the market, make sure your EPC is up to date and that your estate agent is able to promote your energy performance to potential buyers.

Frequently asked questions

Is it legally required to get a new EPC after renovation works?

No, it is not always legally required if the existing certificate is still valid. However, if your works have significantly improved the energy performance of the property, it is strongly advisable to update it before a sale, so that the displayed rating accurately reflects the reality of the property.

How long is an EPC certificate valid in Belgium?

An EPC certificate is valid for ten years. After that period, or following major works, a new certificate must be issued by an approved certifier.

Who pays for the EPC certificate in a sale - the seller or the buyer?

In Belgium, it is the seller who is required to provide a valid EPC certificate at the time of listing the property for sale. The cost is therefore theirs to bear.

Does the EPC rating really affect the sale price of a property?

Yes. Studies of the Belgian property market show that a property rated A or B sells on average 10 to 15% more than an equivalent property rated D or E. In 2026, with rising energy costs, buyers are paying growing attention to this criterion.
