Cost of certificates when selling a house in Flanders

Anyone selling their home in Flanders bears the cost of certificates when selling a house themselves. Count on 700 to 1,500 euros for an average home built before 2001. The amount depends on the age of your home, on the installations it contains and on your municipality. Below you can see which documents are mandatory, roughly what each certificate costs and when you are best off requesting them.

Which certificates are mandatory when selling a home?

Flanders ties a fixed set of documents to the transfer of a home. You need some of them as soon as you advertise, others only at the signing of the preliminary sales agreement.

• EPC (the Flemish energy performance certificate): mandatory from the moment you put your home up for sale. The label must appear in every advertisement.
• Asbestos certificate: mandatory when selling any building constructed before 2001.
• Soil certificate: to be requested from OVAM, the Flemish soil agency, and mandatory for every transfer of land or a home.
• Inspection report of the electrical installation: needed when the installation is more than 25 years old, which in practice is the case for most existing homes.
• Town planning information: requested from the municipality, with information on permits, zoning and any infringements.
• Post-intervention file: mandatory for works carried out after 1 May 2001.
• Inspection of the heating oil tank: only if a fuel oil tank is still present, even when it is out of use.
• Documents from the building manager: for an apartment, including the state of the reserve fund and the works under way.

If you sell in Brussels or Wallonia, different rules apply. The asbestos certificate, for instance, is a Flemish obligation, as is the EPC label: in Wallonia and Brussels the PEB certificate applies instead, and the soil certificate is issued there by bodies other than OVAM. The amounts below therefore apply to Flanders. In that case, ask your notary which list applies to your region.

What does each certificate cost in 2026?

Rates differ per inspector, per municipality and per property type. The amounts below are indicative prices for an ordinary single-family home in Flanders.

Certificate	Indicative price	Validity
EPC	150 to 350 euros	10 years
Asbestos certificate	400 to 800 euros	10 years, shorter with certain findings
Soil certificate (OVAM)	about 60 to 70 euros	limited, requested shortly before the deed
Inspection of electrical installation	120 to 200 euros	25 years with a compliant report
Town planning information	50 to 150 euros	differs per municipality
Inspection of heating oil tank	100 to 250 euros	depends on the type of tank
Post-intervention file	0 to 400 euros	stays with the home

A home built before 2001 with an old electrical installation and a fuel oil tank quickly comes to 900 to 1,500 euros. A more recent home without asbestos risk often stays under 500 euros, because the asbestos certificate falls away there. Always ask for a price in advance and, where possible, have several inspections carried out by the same firm.

When do you request the certificates?

The order determines whether you sell smoothly or lose weeks. You need the EPC and the asbestos certificate before you publish. An asbestos expert often has to have samples analysed in a laboratory, and that takes two to three weeks. Anyone who only calls an expert after a bid has been made holds up the preliminary sales agreement.

The soil certificate and the town planning information usually go through the notary. He requests them as soon as there is an agreement, but some municipalities apply lead times of four to six weeks. So report it immediately once you know you are going to sell.

The electrical inspection is best planned together with the EPC. Both inspectors need access to the same rooms, and a combined appointment saves a call-out cost. Bear in mind that a non-compliant report is not a barrier to the sale: the buyer then has eighteen months to bring the installation into order. You do have to be able to present the report.

Where sellers lose money on certificates

The biggest cost is rarely the certificate itself, but what goes wrong around it. Three situations come up often.

First: having an EPC drawn up without supporting documents. If you have installed roof insulation, replaced windows or had solar panels fitted, the expert only counts these if you can show invoices, technical sheets or photos of the work. Without proof your label comes out one or two levels lower, and that translates directly into the bid you receive.

Second: ordering each certificate separately from a different party. Call-out costs pile up and you lose time following up five files.

Third: having certificates charged on top of an agent's fee you have not compared. Some offices include the entire administrative package in their rate, others pass everything on. That difference easily runs to more than a thousand euros. Anyone who compares several estate agents sees that difference immediately and can negotiate about it before anything is signed.

What the certificates mean for your sale price

A certificate is not just an administrative obligation. In Flanders the EPC label helps steer what a buyer is willing to pay. Since 2023 a renovation obligation applies there: anyone who buys a home with label E or F must bring it up to at least label D within five years. Buyers deduct that renovation cost from their bid, and usually more generously than the works actually cost.

The same goes for an asbestos certificate listing many materials found, or an electrical installation that is not compliant. Every open point gives the buyer an argument to go lower. Knowing what your home is worth with and without those points therefore helps you decide whether to tackle anything before the sale. A free valuation of your home gives you that starting point.

An estate agent who knows your street also knows how buyers in your municipality react to a given label. That judgement differs strongly between a terraced house in Antwerp and a detached home in the Kempen. So have no more than three estate agents look at your home and compare their assessments side by side.

Frequently asked questions

Who pays for the certificates when selling a house?

The seller pays for the certificates. The EPC, the asbestos certificate, the electrical inspection and the soil certificate are all on your account, even when the sale ultimately falls through. The buyer in turn bears the registration duties and the deed costs.

How much do all the certificates cost together in a sale?

For an ordinary Flemish home built before 2001 the total lies between 700 and 1,500 euros. Homes built in 2001 or later do not need an asbestos certificate and therefore often stay under 500 euros.

Is an asbestos certificate always mandatory?

For a sale in Flanders, an asbestos certificate is mandatory for every building constructed before 2001. Homes from 2001 or later fall outside that obligation. From 2032, every owner of such a building must hold a valid certificate, even without a sale.

Can an estate agent arrange the certificates for me?

Yes, many offices take on the entire administration and work with fixed inspectors. Do ask explicitly whether those costs are included in the fee or invoiced separately. You can raise that point straight away when comparing agents.

In short

When selling a Flemish home, count on 700 to 1,500 euros in certificates, and start with the EPC and the asbestos certificate before you advertise. Gather your renovation invoices, because they help determine your label and therefore your price. If you want to know where your home stands today first, request a free valuation.
