The rule is clearer than many sellers expect: the person who instructs the agency is the person who pays it. Because it is the seller who signs the mandate authorising the agency to sell, it is the seller who owes the commission when the sale completes. The buyer's side of the transaction has its own separate costs, but the agency fee is not among them.
Keeping the two sides distinct avoids a common confusion. A buyer in Wallonia pays registration duties, now 3% for an own and sole home since 1 January 2025 (source: Wallonia government/Lydian, 2025), together with the notary's fees, but not the selling agent's commission. The seller's agency fee sits on the seller's side of the ledger and is settled through the sale.
The counter-intuitive comfort in Easyhome's model is that the fee follows the result. Although the seller is the party who pays, that liability only arises if the agency delivers. The commission is, in principle, only due on a completed sale, so a seller whose property does not sell pays no commission. In effect, the fee is tied to performance rather than simply charged for listing the property.
For your own numbers, both the fee and how it is settled at completion are set out in the mandate, so ask your adviser to walk you through them.
