Electrical checklist for expats in Mons: what to prepare

Before any electrical work begins in your Mons home, have two documents ready on site: the single-line diagram (schéma unifilaire) and the layout plan (plan de position), both drawn using RGIE-compliant symbols. Confirm earthing continuity and RCD function, and hire an electrician who knows Walloon inspection requirements. That is the short version. Everything below tells you exactly how to do it.
Quick pre-job checklist:
Locate your electrical panel and confirm it is accessible
Find your EAN number (on your electricity bill or meter)
Gather any previous inspection report (procès-verbal or PV)
Check whether single-line and layout diagrams exist and are on site
Confirm your electrician carries public liability insurance and RGIE experience
Note any recent changes (solar panels, EV charger) that need updating on diagrams
Pro Tip: WhatsApp Eutradesmen on +32 466 900 281 before work starts. An English-speaking electrician can check your dossier and tell you what is missing in minutes.

Your step-by-step electrical work checklist for Mons expats
Before the work
Share your EAN number, floor plans, and any previous PV with your electrician
Agree in writing on the scope: new circuits, socket additions, panel upgrades
Shut off the relevant circuits at the panel and confirm isolation with a voltage tester
Remove furniture or obstructions blocking panel or cable routes
During the work
Ask the electrician to label every new circuit clearly at the panel
Confirm continuity tests and RCD checks are carried out as work progresses
Take photos of cable routes before walls are closed — you will need these later
After the work
Collect the updated single-line diagram, updated layout plan, and a detailed invoice
Request the test certificate showing earth resistance and RCD results
Store the full dossier near the panel and keep a digital copy
Pro Tip: Ask your electrician to hand you the updated diagrams before they leave. Chasing paperwork weeks later is far harder than asking on the day.
What documents does the Walloon inspector expect?
Two documents are mandatory at inspection: the single-line diagram and the layout plan. Both must use the official RGIE graphic symbols. Since the Royal Decree of 5 March 2023, the symbols list was updated to include EV chargers, photovoltaic sources, and home batteries, so older diagrams may need revising.
What the inspector expects to see:
Single-line diagram showing every circuit, breaker rating, and RCD
Layout plan (one per floor) showing socket, light, and appliance positions
Both documents using current RGIE graphic symbols
Paper copies physically on site, not just on a phone or laptop
If diagrams are missing, some inspection bodies can draft them on site for an additional fee, but this lengthens the visit and costs more than preparing them in advance. The electrical dossier guidance from Bativolt confirms that clear, up-to-date schematics are a core compliance obligation under RGIE Book 1.
Pro Tip: Keep the full dossier in a plastic wallet taped inside the panel door. Inspectors appreciate it, and it saves everyone time.
How does a Walloon electrical inspection actually work?
Inspectors treat the visit as a safety verification, not a paperwork exercise. They need accurate documentation to test safely and to accept liability for their findings.
Aspect | Typical figure |
Inspection duration | typically 30–90 minutes |
Report turnaround | usually 24–48 hours |
Booking lead time | generally 24–48 hours |
Residential periodicity | Regularly scheduled periodic inspections |
Short-term rental periodicity | Periodic inspections scheduled more frequently for rental properties. |
The core checks inspectors perform include earth resistance and continuity, RCD functional tests, insulation checks, distribution board condition, and verification that the single-line diagram matches the live installation. The official PV is issued in French or Dutch. If you need an English summary, request one when booking.
After a non-conformity finding, you have 18 months to carry out corrective work before re-inspection in a property sale situation.
Common inspection failures and how to avoid them
Missing or out-of-date diagrams are the single most frequent reason inspections stall. Beyond paperwork, inspectors regularly flag poor earthing continuity, non-functioning RCDs, and sockets placed too close to baths or showers.
Typical failures and fixes:
Missing diagrams: Have an electrician produce or update them before booking
Poor earthing: Ask for an earth resistance test and remedial bonding if values are high
RCDs not tripping correctly: Replace faulty units; a 30 mA RCD is required for bathrooms
Sockets near baths or showers: Regulations set minimum safety distances from bath and shower edges; non-compliant sockets must be relocated or removed
Inaccessible panel: Clear the area before the inspector arrives
Bathrooms deserve particular attention. Belgian rules divide the room into protection volumes (0, 1, 2, and 3), each with strict limits on what electrical equipment is permitted. A socket in the wrong volume is an automatic non-conformity. For detailed socket placement rules, the 2026 socket compliance guide covers the specifics clearly.
Pro Tip: After corrective work, ask your electrician to document every fix with a photo and a brief note. Bring that record to the re-inspection — it speeds the process considerably.
How do you find a qualified English-speaking electrician in Mons?
Start with verification, not price. A qualified electrician in Wallonia should be able to show Belgian registration, public liability insurance, and demonstrable RGIE experience, including producing inspection-ready diagrams.
Verification checklist:
Belgian professional registration or accreditation
Public liability insurance (ask for a certificate)
Experience with Walloon inspections and PV dossiers
References for diagram production and inspection-ready delivery
Questions worth asking:
Can you produce or update the single-line and layout diagrams?
What test equipment do you use for earth resistance and RCD checks?
How long after the work will updated diagrams be ready?
What is your written guarantee on the work?
Red flags: vague invoices with no scope detail, refusal to provide diagrams, no written guarantee, and reluctance to show proof of accreditation. For a broader overview of electrician compliance services in Belgium, that guide covers what to expect from a qualified contractor.
What do inspections and small jobs cost in Mons?
Inspection bodies charge per project rather than per hour. Booking lead time is typically 24–48 hours, the inspection itself runs 30–90 minutes, and the report arrives within 24–48 hours. If diagrams are missing and the inspector drafts them on site, expect an extra charge of around €50 on top of the standard fee.
What affects the total cost:
Whether diagrams need producing or updating
Earthing remedial work (bonding, new earth rod)
RCD replacement or panel upgrades
Number of circuits and property size
Re-inspection fee if non-conformities are found
Small remedial jobs (replacing an RCD, relocating a socket) are typically charged per task. Panel upgrades or full rewires are quoted per project. Getting a written quote before work starts protects you from surprises.
Who is responsible — tenant or landlord?
Major compliance issues and statutory inspection obligations fall to the property owner. Minor wear-and-tear repairs (a broken socket cover, a blown fuse) may be the tenant’s responsibility depending on the lease.
Before signing a rental agreement:
Request the most recent electrical inspection PV from the landlord
Check the PV date and whether any non-conformities remain open
Confirm in writing who arranges and pays for any remedial work flagged in the PV
Pro Tip: Keep copies of all inspection reports, invoices, and written requests to your landlord. If a dispute arises, that paper trail is your strongest protection.

Our perspective on electrical safety for expats in Mons
Expats often arrive in Mons with a long to-do list and electrical compliance somewhere near the bottom of it. That is understandable. But the paperwork side — diagrams, test certificates, a clear PV — is what protects you when you sell, rent, or simply need a repair done quickly. We have seen how a missing single-line diagram can turn a 45-minute inspection into a half-day event with extra costs. Getting the dossier right first time means fewer re-inspections, faster meter activation, and a smoother handover if you ever sell or sublet. We also know that reading a French-language PV when you are not fluent is genuinely confusing. That is why we always explain findings in plain English and follow up on any warranty or liability questions after the work is done. The checklist in this article is the same one we run through with every client before we book their inspection.

FAQ
What documents must I have ready for a Walloon electrical inspection?
You need a single-line diagram (schéma unifilaire) and a layout plan (plan de position), both using current RGIE graphic symbols, physically present on site. Missing either document is a primary reason inspections fail.
How long does an electrical inspection take in Mons?
Residential inspections typically last 30–90 minutes, with the official report delivered within 24–48 hours. Most accredited bodies can book an appointment within 24–48 hours of your request.
Who pays for electrical repairs in a Belgian rental property?
Major compliance and safety issues are the landlord’s responsibility. Minor wear-and-tear repairs may fall to the tenant depending on the lease terms. Always request the current PV from your landlord before signing.
What happens if my installation fails the inspection?
You receive a non-conformity PV. In a property sale situation, you have 18 months to carry out corrective work before re-inspection. Minor remarks require remediation but carry no immediate penalty.
