No. Joint ownership changes nothing about the EPC obligation. Any sale of a residential building in Wallonia needs a valid EPC (PEB) before advertising, whoever owns it. Co-owners simply commission one certificate together for the shared property (ImmoAnalyse, 2026).
The EPC requirement attaches to the property and the act of selling it, not to the number of owners. So whether a home is owned by one person, a couple, several heirs in indivision or legal cohabitants, the same rule applies: a valid EPC (PEB) must exist before the listing goes live and the energy label must appear in the advertisement (ImmoAnalyse, 2026). There is no joint-ownership exemption, because the buyer’s right to energy information does not depend on the sellers’ internal arrangements.
In practice joint ownership makes the EPC easier, not harder, because the certificate covers the building as a whole. Co-owners do not each order a separate EPC; they commission one certificate for the shared property, and its cost is typically shared in the same proportion as ownership, alongside the other sale expenses. One certifier visits, one document is issued, and it serves all the sellers. Its 10-year validity applies to the property regardless of who the owners are.
The counter-intuitive nuance is that the real complication in a joint sale is consent, not certificates. Belgian law holds that no co-owner can be forced to remain in indivision, but selling to a third party normally requires the agreement of all co-owners; if one refuses, the others may seek a court-ordered sale (licitation). The EPC, by contrast, is a straightforward shared task that any one of the owners can arrange on behalf of all. So the honest answer to selling difficulties in a jointly owned home is that they come from aligning the people, not from the energy paperwork.
For an apartment in a co-ownership building, note the distinction: the seller of a single unit needs an EPC for their own flat, while the building’s common parts have their own separate arrangements handled by the syndic. Either way, no owner, sole or joint, can lawfully skip the certificate.

- A valid EPC (PEB) is needed before advertising in every case.
- Co-owners commission a single certificate for the shared property.
- The cost is usually split in proportion to ownership shares.
- Validity is 10 years for the property, regardless of the owners.
- The genuine hurdle in a joint sale is unanimous consent, not the EPC.
- For a flat, the unit needs its own EPC; common parts are separate.
