EPC certificate: how long is it valid when you sell?

The validity period of an EPC certificate is ten years from the date it was drawn up, in Wallonia, Brussels and Flanders alike. That sounds simple enough. In practice, many sellers discover at the point of signing that their document no longer covers the sale, or that it describes a home which has since changed. Here is what the ten-year rule really covers when you put a property on the market.

Ten years, counted from the date it was drawn up

The clock starts on the date the accredited certifier drew up the document, not the date you received it and not the date you put the property on the market. That date appears on the first page of the certificate, next to the identification number. If your certificate dates from March 2017, it stops having effect in March 2027, however far along your file happens to be.

The rule is the same in all three regions, even though the document does not go by the same name everywhere. In Wallonia and Brussels it is the PEB certificate, drawn up by an accredited certifier. In Flanders it is the EPC, produced by a type A energy expert. Calculation methods differ from one region to the next, which is why the same home can end up with a slightly different label depending on the framework used. The validity period, however, does not change.

An expired certificate has no value. It cannot appear in a listing, it cannot be handed to the buyer, and it cannot serve as a basis for the notary.

When exactly does the certificate need to be valid?

Three moments matter. First, publication of the listing: the energy label and the specific consumption figure have to appear there, which means the certificate must exist before the first photo goes online. Then the viewings, during which you need to be able to show the document to any prospective buyer who asks. And finally the signing, at the compromis and then at the notarial deed, where the certificate joins the file.

The notary checks this as a matter of course. Without a valid certificate they will not pass the deed, and the signing date slips while a certifier is brought in. That delay is counted in weeks rather than days, particularly in spring and in September when requests pile up.

That is why it is better to deal with the certificate at the very start of the process rather than when you are fixing a date at the notary's office. A good agent will remind you of this at the first appointment. If you are still weighing up which professional to entrust your property to, you can compare several agents active in your municipality before committing. Our other articles set out the EPC obligations that apply to a sale.

What cuts the validity short before the ten years are up

Three situations bring an otherwise young certificate to an end.

The first: a new certificate being drawn up for the same home. As soon as a certifier produces one, it replaces the previous document. So you cannot choose to present the older one because it showed a better label.

The second: a change to the unit itself. If you split a house into two apartments, or combine two studios, the resulting units no longer match the ones described in the certificate. You have to start again, unit by unit.

The third: demolition followed by reconstruction, or a renovation so extensive that the building is treated as new construction. The certification procedure for building works then takes over.

Conversely, ordinary works do not void your certificate. Replacing a boiler, insulating a loft or fitting double glazing does not make the document invalid. The certificate stays valid until its expiry date, but it goes on describing the home as it was before the works.

After renovation works, should you have the certificate redone?

Nothing obliges you to, as long as the ten-year period is still running. So the question is not a legal one, it is a commercial one.

A buyer reading a listing compares labels. If you have insulated your roof and replaced your heating system, but your listing still shows an F label drawn up six years ago, you pay twice: once for the works, and once in the negotiation. Price gaps between labels are real, and a poor label serves as a bargaining argument even when the property has been improved.

Having a certificate redrawn costs a few hundred euro, an amount worth weighing against the negotiating room an out-of-date label hands the buyer. We have set out the cost of an EPC certificate after works as well as what each label means. To find out what your property is worth today, with its current label, request a free valuation of your home.

A certificate that expires during the sale

A Belgian property sale rarely takes less than four months between going online and the notarial deed. Between the compromis and the deed, allow several more months in most files, while the buyer finalises their mortgage and the notary gathers the documents.

So do the arithmetic before you publish. If your certificate expires in less than six months, assume it will not last to the end of the sale. Redoing it straight away costs less than a postponed deed, and it spares you having to explain to an already committed buyer why the signing is being pushed back.

The check takes a minute: take out the document, look at the date it was drawn up, add ten years. If the expiry falls within the next two years, deal with it now. An experienced agent runs this check automatically at the valuation stage, at the same time as verifying the planning position, the post-intervention file and the soil attestation. This is precisely the kind of detail that separates a well-prepared mandate from a file that springs a leak three months later.

What to remember before putting your home on the market

Ten years, counted from the date it was drawn up, in all three regions. The certificate has to be valid at the time of the listing, the viewings and the signing. A new certificate cancels the old one, and a change to the unit means starting over, but improvement works do not make the document invalid.

The real risk is not a fine, it is the calendar: a certificate that expires mid-file delays the deed, and a certificate that is still valid but overtaken by your works costs you money in the negotiation.

If you are preparing a sale, have this point checked by a local professional before you publish anything. You can compare up to three IPI-accredited agents in your region free of charge and with no obligation, then choose the one whose approach suits you. Each knows their market, their buyers and the certifiers who turn up quickly in your municipality.
