An electrical compliance certificate (CE) for a home in Wallonia usually costs between 100 and 170 euros for the inspection. It is carried out by an accredited inspection body, and a favourable report on a domestic installation is valid for 25 years (Belgian inspection bodies, 2026).
Before a home changes hands, its fixed electrical installation must be inspected against the RGIE (the Belgian general regulation on electrical installations). The inspection is performed by an accredited body, and the fee is modest: expect roughly 100 to 170 euros for a standard dwelling (Belgian inspection bodies, 2026). The inspector checks earthing, the differential protection, circuit ratings, the fuse board and the presence of a compliant installation schedule.
The result is a report, and it comes in one of two flavours. A favourable (compliant) report is valid for 25 years, an unusually long shelf life, which means a home inspected and passed years ago may still hold a valid certificate today (Belgian inspection bodies, 2026). An unfavourable (non-compliant) report is still perfectly legal to sell with, but it starts a clock: the buyer must bring the installation up to standard, and have it re-inspected, within 18 months of the deed.
The counter-intuitive point sellers often miss is that a negative certificate does not block the sale. You are not obliged to rewire the house before selling; you simply must hand over the inspection report, favourable or not, so the buyer knows what they are taking on (Belgian inspection bodies, 2026). Many older Walloon homes sell every year with a non-compliant report and a price that reflects the works to come.
Costs to keep in mind beyond the inspection are the works themselves if the installation fails, which vary widely from a few minor fixes to a full rewire, and the re-inspection fee once the works are done. Ordering the inspection early in your sale preparation lets you decide, with clear eyes, whether to remedy defects yourself or let the price and the 18-month buyer deadline do the work.
