Background
Practical guidance on Belgium’s AREI regulations, checked on 19 September 2026. The required inspection depends on the installation, its history and the specific work involved.
In this article
Make it clear what you did and what's still open.
Describe which parts you built or modified, what happened by other performers and which parts were preserved. That's not an exam for the application. However, it does prevent an accompaniment for one new part from being understood as an assessment of the entire home. Also mention if you still have doubts about an existing version.
Ask for help before continuing or finishing your insecure work. This article does not provide any wiring instructions or a list with which you can prove safety. Do not open a cabinet or take electrical measurements to add information to your enquiry. An inspection appointment is not a permit to use an unrated installation in advance.
What's in the household file?
The FOD asks for at least single-line diagrams, installation layout plans and, if available, the EAN code. The single-line diagram describes the electrical structure; the installation layout plan shows where the components are located. The dossier shall also contain previous control reports and technical documentation.
Make sure that the documents belong to the same address and execution. A schedule prior to the renovation can be useful history, but does not automatically tell what changed later. Updating a document therefore requires more than a new date field or a signature. Ask which recording is needed to describe reality correctly.

A scheme is not an independent approval
In the case of new domestic installations and major operations, the manager shall draw up the plans. In compliance, that person and the approved organism shall date and sign the documents. The AREI therefore does not reserve formatting exclusively for electricians. A drawing does not prove compliance in itself.
In the case of shared execution, agree on which parts are being examined and on what data the documents are supported. Do not ask to sign an unseen schedule as if implementation has already been established. We can discuss support for your existing situation; this does not take over or guarantee previous work without research.

What if the first check shows non-compliance?
In the event of an unfavourable conformity inspection before commissioning, the relevant part shall not be put into service. The non-compliances need to be remedied and a new check is needed. The rules after a sales check or periodic visit are not identical; therefore do not rely on one general recovery period for each report.
Ask for a proposal in which the points identified and the necessary follow-up can be identified. Repair, modification of documents and rechecking may be separate items. Keep the full report. Only the conclusion can be transmitted without important information on the demarcation and follow-up.

This is how you make the assignment concrete with Wattra
Specify your municipality, why the control is necessary and why you carried out your own work. Please indicate which documents already exist and what help you are looking for. Wattra can organise an inspection for its own installations, installations of other performers and DIY projects. Acceptance of additional recordings, schedules or recovery shall be discussed in advance for each assignment.
Ask for some coordination, external control and any preparatory work costs. A quote visit is not an inspection and an application is not yet a confirmed appointment. We help customers throughout Flanders, from Sint-Niklaas and the Waasland. The inspection body remains responsible for the official assessment and inspection report.
What you can prepare now
- Name your own work, work of others and keep sharing.
- Gather diagrams, plans, equipment details and previous reports.
- Report uncertainties before further implementation.
- Arrange organization, professional recording and recovery separately.
Frequently asked questions
Can Wattra only arrange the inspection?
You can ask that particular question. List the building type, the cause and your available file. Any additional support is not implied as included.
Does counseling guarantee that I'll pass at first checkup?
No. The independent assessment remains with the recognized inspection body. A prior recording or document assignment is not a pre-issued positive report.
