A conform electrical certificate is the official inspection report proving your electrical installation meets Belgium’s RGIE/AREI safety rules. Only an accredited inspection body can issue it, not your electrician or yourself.
Three facts worth knowing straight away:
Who issues it: an approved inspection body accredited by FPS Economy and BELAC, never the installer.
How long it lasts: a compliant domestic installation is generally valid for up to 25 years under RGIE / AREI, unless major works reset the clock.
Why you’ll need one: grid connection, selling your home, or adding high-power equipment like an EV charger or heat pump.
If any of those apply to you right now, your next move is simple: call an English-speaking electrician or an accredited inspection body and get the previous certificate and wiring diagram ready before anyone shows up. Having those two documents to hand on day one shaves real time off the whole process.

What does conform mean in electrical terms?
“Conform” here means your installation has been checked against RGIE (Règlement Général sur les Installations Électriques) or AREI (Algemeen Reglement op de Elektrische Installaties), Belgium’s binding electrical safety standard. An inspector doesn’t just glance at your fuse box and nod. They test earthing continuity, check differential protection, verify labelling, and compare what’s actually in the wall against what should be there under the regulation.
The report that comes out the other end lists exactly what was checked, flags any non-compliances found, states the inspector’s accreditation number, and carries a signature and date. That’s the legal document. A tidy wiring diagram from your installer, however professional it looks, is not the same thing.
Here’s the distinction that trips people up most often: your electrician builds the installation, but they cannot legally sign off on it themselves. Only the accredited inspection body can issue the certificate, because the whole point of the system is an independent check, not a self-assessment. A plan drawn up during renovation is genuinely useful for briefing your electrician, but it’s a planning aid, not a substitute for the actual certificate.
What separates a compliant report from a non-compliant one:
A compliant report confirms the installation meets RGIE/AREI with no outstanding issues, and it becomes your reference document for up to 25 years.
A non-compliant report lists specific defects, with a deadline attached for fixing them, and typically requires a follow-up visit to confirm the repairs.
Either way, the report itself, not the electrician’s invoice or your own notes, is what a grid operator or notary will ask to see.
When do you actually need one?
Most homeowners only think about certification when something forces the issue, usually a connection, a sale, or a big renovation. Recognising the trigger early saves you from a last-minute scramble.
You’ll need an inspection and certificate in these situations that involve adding circuits and high-power equipment:
New installation before the network operator connects electricity to the property.
Major modification, including new circuits or a new distribution board.
High-power equipment, such as an EV charger, heat pump, battery storage, or solar inverter. Adding any of these materially changes the installation and grid operators will not sign off without an updated certificate.
Selling a property, in most residential transactions.
Re-energisation after an emergency, such as a fire or major fault repair, or a significant power upgrade.
Grid operators like Sibelga, Fluvius, ORES, and RESA will not connect or upgrade a supply without a valid certificate in hand, and notaries check for one before completing a sale. If you’re simply swapping a broken socket or replacing a light fitting without touching fixed wiring, you’re generally in the clear. It’s the structural changes, new circuits, new boards, new high-draw appliances, that pull you back into inspection territory.
Who can issue the certificate, and how do you check it’s genuine?
Only an “organisme agréé” (approved body), authorised by FPS Economy and accredited under ISO/IEC 17020, can legally issue a conformity certificate. This isn’t a badge any inspection firm can print on their own letterhead. Accreditation is monitored, audited, and revocable, which is exactly why grid operators and notaries trust the paperwork without re-checking the wiring themselves.
Verifying a report is genuine takes two minutes if you know what to look for:
Check the accreditation number printed on the report, something formatted like “663-INSP”, and cross-reference it against the official FPS Economy list of accredited inspection bodies.
Look for the individual inspector’s ID number, separate from the body’s accreditation number.
Confirm there’s a clear issuer contact, a registered office and phone line, not just a mobile number scrawled at the bottom.
If in doubt, ring the accredited body directly and ask them to confirm they issued the report you’re holding.
Pro Tip: Never accept a certificate that only shows a company logo with no accreditation number. Genuine reports always carry a traceable number you can look up independently, and any inspector worth hiring will expect you to check it.
How do you get a conform electrical certificate?
The process is more predictable than most homeowners expect, once you know the order of operations.
Decide whether the work needs inspection. New circuits, a new board, an EV charger, or a sale all qualify. A single socket swap usually doesn’t.
Contact an approved inspection body directly, or ask your electrician to arrange it. Most electricians who do compliance work regularly already have a relationship with a local accredited body and can book the visit for you.
Prepare your documents. Have the previous certificate, the wiring diagram, and any renovation plans ready before the inspector arrives.
On-site inspection. The inspector tests the installation against RGIE/AREI and records findings on the spot.
Receive the report. If it’s compliant, you’re done for up to 25 years. If not, you’ll get a list of defects and a deadline.
Re-inspection if required. Once remedial work is finished, the same body checks again and issues the final certificate.
What to have ready before the inspector shows up:
Previous compliance certificate (if one exists)
Wiring diagram or as-built plans
Clear, unobstructed access to the distribution board
Contact details for the electrician who did any recent work
A note of anything new added recently, EV charger, solar inverter, extra circuits
On timing, expect a booking lead time of roughly one to three weeks depending on the region and body’s schedule, an inspection visit itself lasting under an hour for a typical home, and the written report following within a few days. Reinspections after remedial work usually slot back in faster, since it’s a narrower, targeted check rather than a full audit.
What do inspectors actually check on site?
Inspectors work through a defined list rather than eyeballing your fuse box and guessing. Knowing what’s on that list means you can catch obvious problems before the visit and avoid an easily preventable fail.
Inspection Item | What The Inspector Verifies |
Main distribution board | Correct sizing, secure connections, clear circuit identification |
Differential protection | Residual current devices trip correctly and are appropriately rated |
Circuit labelling | Every circuit is clearly and accurately marked at the board |
Earthing and grounding | Continuity throughout the installation, correct resistance values |
Protective devices | Circuit breakers match the cable ratings they protect |
Accessible cables and connections | No exposed wiring, safe junctions, proper enclosure |
Recent modifications | New circuits or equipment match approved standards |
When an inspector finds something wrong, it goes into the report as a documented non-compliance with a deadline attached for the fix, rather than a vague verbal warning. That deadline matters. Miss it and you may need to rebook the whole visit rather than just the reinspection.
A few habits make life easier on inspection day. Keep the previous report taped or stored near the main panel so it’s not buried in a drawer somewhere. Label your circuits clearly if they aren’t already. Clear physical access to the board, boxes stacked in front of it is a genuinely common and entirely avoidable delay. And note down anything you’ve added recently, an EV charger or solar inverter, so the inspector knows exactly what’s changed since the last visit.
What does it cost and how long does it take?
Costs vary by region, the size of the installation, and how much remedial work, if any, is needed. A small flat with a modern board costs less to inspect than a large house with an older, more complex distribution system.
The main factors that push the price up or down:
Size of the distribution board and number of circuits. More circuits mean a longer inspection.
Remedial work required. A failed inspection with several defects costs more overall once you factor in the electrician’s repair time plus the reinspection fee.
Travel and fast-track fees. Rural or less accessible properties, or urgent bookings, sometimes carry a premium.
Type of property. New builds tend to be more straightforward than older installations with a longer, more tangled history of modifications.
On timing, budget for a booking window of one to three weeks, an inspection visit of thirty to sixty minutes, report issuance within a few working days, and, if repairs are needed, however long your electrician needs plus a further reinspection slot.
Statistic Callout: Once you pass, a compliant domestic installation is typically considered valid for up to 25 years under RGIE/AREI. That single figure is the anchor for almost everything else in this article. Urgent re-inspections outside that cycle are possible, but they tend to cost more and get booked at a premium.
What happens if your installation fails inspection?
A failed inspection isn’t the end of the process, it’s simply the next stage of it. Here’s how it plays out in practice.
You receive the non-compliance list and a deadline. The report specifies exactly what needs fixing and by when.
You arrange a qualified electrician to carry out the remedial work. This is where a team like Eutradesmen’s electricians can step in to handle everything from a board upgrade to rewiring a single non-compliant circuit.
The electrician documents what was fixed. Keep this paperwork; the reinspection body will want to see it.
You schedule a reinspection with the same accredited body. They check specifically the items previously flagged, not the whole installation again from scratch.
Selling a property with a non-compliant report doesn’t automatically kill the sale. The notary records the non-compliance in the deed, and the buyer typically has 18 months to bring the installation up to standard. That said, expect it to affect price negotiations, buyers factor in the cost of fixing what’s flagged.
One more thing worth flagging: some insurers require a valid conformity certificate to honour a claim after a major electrical incident, such as a fire linked to faulty wiring. If your certificate has lapsed and something goes wrong, that gap can complicate a claim at exactly the moment you need it to go smoothly.
How long is a certificate valid?
For most domestic installations, a compliant report holds its validity for up to 25 years from the date of the last positive inspection under RGIE/AREI. That’s a genuinely long window compared with many other safety certifications homeowners deal with, and it’s easy to forget the certificate exists until you need it again.
A few things shorten that interval:
Non-compliance requiring faster follow-up. A report with defects doesn’t reset to a fresh 25-year clock until those issues are fixed and reinspected.
Frequent changes to the installation. Adding circuits, boards, or high-power equipment triggers a new inspection regardless of where you are in the 25-year cycle.
Grid-operator-specific requirements. Some connection upgrades trigger their own inspection regardless of your certificate’s remaining validity.
Store the certificate near your main panel, not in a filing cabinet three rooms away. Notaries, inspectors, and grid operators will all ask for it at some point, usually with limited notice, and digging through old paperwork under time pressure is exactly the kind of stress this whole system is meant to avoid.
How do you make the inspection go smoothly?
A few practitioner habits separate an inspection that finishes in twenty minutes from one that drags on with follow-up visits.
Pro Tip: Keep an up-to-date wiring diagram and grounding plan taped inside or near the distribution board. Inspectors move faster when they can see the intended layout rather than reverse-engineering it from the wiring itself, and that speed often means fewer questions and fewer chances for something to get missed.
Bring your electrician into the conversation early if you’re planning major works, before the walls go back up, not after. An installation built to RGIE/AREI standards from the outset avoids the far more expensive scenario of ripping out plasterboard to fix something that should have been right the first time.
Before accepting any certificate, whether from a new inspection or one handed to you during a property purchase, confirm the issuing body’s BELAC accreditation and the individual inspector’s ID number printed on the report. It takes minutes and it’s the single best defence against an invalid or fraudulent document.
A practical note from Eutradesmen
Electrical compliance sounds intimidating until you break it into the steps above, and most of the anxiety we see from clients comes from not knowing what to expect on the day, not from the inspection itself. Our approach has always been safety first: if a report comes back with defects, we’d rather do the remedial work properly, including a full rewiring where the installation genuinely needs it, than patch something that fails again in six months.
If you’re facing an inspection soon, the single most useful thing you can do today is book an English-speaking electrician who can prepare the installation properly and liaise directly with the accredited inspection body on your behalf. And if you’re preparing a property for sale or reoccupation, it’s rarely just the wiring that needs attention. A handyman for the small remedial jobs and a decorator to freshen up walls after panel work often go hand in hand with the electrical side of getting a home sale-ready.
Get your installation certificate-ready with Eutradesmen
Eutradesmen is the alternative to juggling separate contractors for every stage of getting compliant: our English-speaking electricians handle the remedial work, the panel upgrades, and the circuit labelling, then liaise directly with the accredited inspection body so you’re not the one chasing paperwork between two organisations.
With over 20 years’ experience across Brussels (including Ixelles, Uccle, and Schaerbeek), Waterloo, Tervuren, and Leuven, we’ve handled everything from a straightforward board swap to a full rewiring job ahead of a sale completion date. We’ve also fixed the small things that come with any inspection prep, a flat-pack wardrobe that needed assembling before the buyer’s viewing, a leaking WC repaired the same afternoon, a garden tidied up before photos went online. If your property needs a fresh coat of paint after electrical work opens up a wall, our decoration and painting team can finish the job so the room looks sale-ready, not mid-renovation.
If you’ve had a failed inspection, or you’re planning works that will trigger one, get in touch now for a free quote. WhatsApp us your situation, previous report, deadline, and photos of the panel if you have them, and we’ll tell you honestly what’s involved and what it will cost.

FAQ
What is a conformity certificate?
A conformity certificate is the official report from an accredited inspection body confirming an electrical installation meets RGIE/AREI safety standards, required before grid connection, after major works, or when selling a property.
Where can I get a CoC certificate?
You get a Certificate of Conformity from an FPS Economy approved, BELAC accredited inspection body. Your electrician can usually arrange the booking, or Eutradesmen’s electricians can coordinate the whole process for you.
Who provides a Certificate of Conformity?
Only an accredited inspection body authorised by FPS Economy and accredited under ISO/IEC 17020 can legally issue the certificate, never the installer or homeowner directly.
Can I make my own Certificate of Conformity?
No. The certificate is a legally auditable document that must come from an independent, accredited inspection body; a self-drafted report or an installer’s checklist has no legal standing with grid operators or notaries.
