March 2026. I am finishing a provisional reception in Mons, a 3-façade house, young first-time-buyer couple. Everything goes well until it is time to inspect the electrical panel. The RGIE certificate is missing. The contractor tells me, “It’s coming tomorrow.” Bad sign. Here is the full sequence of this case, which lasted six weeks and cost the contractor €8,400 in remedial works — step-by-step account, to use as a model if you face a similar situation.
The defect discovered
I ask to see the report from the approved body (Vinçotte, OCB or equivalent). Contractor’s reply: “Not been done yet, but we’ll handle it in the coming days.” The panel itself shows visible anomalies even before any official inspection:
- No 30 mA differential on the bathroom circuit (mandatory RGIE)
- Undersized cable on the electric oven (2.5 mm² instead of the 6 mm² required)
- No clear labelling of circuits
- Earthing not tested with a megohmmeter
Immediate refusal to sign reception without explicit reservations. Note in the minutes: “Electrical reception refused without production of a compliant RGIE certificate. Four visible anomalies established contradictorily, photographed in annex.” Copies to both parties, signatures of the owner and myself as third-party expert.
“Without a compliant RGIE certificate, the meter cannot be opened by ORES. You are living legally without electricity. It’s that simple.”
The legal situation
The RGIE (General Regulation on Electrical Installations) is a technical text enforceable since 1981, overhauled in 2020. Without a compliance certificate issued by one of the five approved bodies in Belgium (Vinçotte, OCB, BTV, ACEG, AIB-Vinçotte), ORES will never open the final meter. And without a final meter, your home is legally habitable but materially uninhabitable.
In case of documented non-compliance, the owner has several cumulative recourses:
- Reception refusal under Article 9 of the Breyne Law (defect affecting habitability)
- Formal notice to the contractor (Article 1184 of the old Civil Code, Articles 5.83 et seq. of the new Code)
- Activation of the retention guarantee (5% of the total price)
- Application to the urgent-procedure judge for remediation under penalty payment
The full text of the RGIE is available on economie.fgov.be — electrical technical rules.
The recourse engaged
D+5: registered formal notice sent to the contractor, citing Article 71 of the Breyne Law and setting a 15-day deadline to produce the certificate. The contractor had three options:
- Prove compliance by having an approved inspector pass within a fortnight
- Redo the deficient works and have an inspector pass again
- See the retention guarantee immediately called via bailiff
D+12: response from the contractor, registered: he agrees to have a Vinçotte inspector come. First positive sign. D+18: inspector passes, finds 4 non-compliances: bathroom differential absent, oven section insufficient, earthing not tested, circuit labelling incomplete.
The outcome
On D+22, the Vinçotte report is officially delivered to both parties. On D+38, after 16 days of additional work by the electrician (entirely at the contractor’s expense), the repairs are done: addition of a 30 mA differential, replacement of oven cable with 6 mm², megohmmeter test, labelling redone. On D+42, new Vinçotte check: compliant. The retention guarantee is released only on D+45, after receipt of the contradictorily signed reservation-lifting minutes.
Total cost borne by the contractor: about €8,400 (€4,200 of works + €2,800 of daily penalties provided in the contract + €1,400 of inspector and expert fees). Cost to the owner: €0 apart from the stress of the six weeks.
Pitfalls to avoid
- Do not sign on the basis that “the certificate is coming tomorrow”: demand it on the day
- Beware of unknown bodies: only 5 are officially approved in Belgium
- Systematically keep the ORES commissioning minutes with your owner’s file
- Photograph the electrical panel head-on with labels readable
- If you discover non-compliance after moving in, activate the two-year warranty within 2 years
What next?
If your electrical file is in doubt or the RGIE certificate is missing, have it validated by an independent expert before signing the minutes. My practice offers an electrical expertise with a partner approved inspector, or a broader construction audit including the other technical lots.
