CD Engineering - Electrical installation control Brussels

The compulsory electrical inspection consists of checking the conformity of the electrical network according to the rules described in the RGIE (Règlement général des installations électriques). The latter defines the rules of the electrical installation. As regards the inspection procedure, the crucial elements of the existing electrical installation are examined:

• The correct operation of the differential circuit breakers and the resistance of the earth connections;
• The insulation resistance;
• The presence of residual differential devices;
• The distribution boards;
• The dispersion resistance of the earth connection;
• Etc.

Do you still have questions about the process of an electrical inspection? Contact CD Engineering and its team of professional electricians to find out more.

The inspection of your electrical installations is mandatory in various situations:

• For a new construction: an electrical inspection is mandatory before the first use of an electrical network and the connection of the meter to the electrical installation;
• When work is carried out or any major modification is made to an existing electrical installation: addition of an extra circuit, non-identical replacement of an electrical distribution board, etc;
• When selling your home or any property: the electrical inspection is required if the electrical installation dates from before 1 October 1981.

In other circumstances, you are not required to carry out a specific electrical inspection. However, it is important to remember that an electrical installation up to standard is essential to avoid the risk of fire and electrocution. Therefore, a regular electrical inspection will ensure the electrical safety of the home or industrial building.

During an electrical inspection in Brussels, here are the documents you can provide to your approved electrician:

• The EAN code (European Article Numbering) of the electricity meter. This code identifies the connection to the network and is shown on your electricity supplier’s bill;
• If there has been a previous negative inspection, the report of the previous electrical inspection;
  The single-line diagram of the electrical installation: this is a schematic representation of an electrical installation showing the composition of each elementary circuit. This diagram also indicates the interconnection of the elementary circuits to form the electrical installation;
• The positional drawings of your electrical installation. This plan indicates the position of the electrical panels, the connection boxes and junction boxes or the socket outlets. The position plan also shows the location of switches and appliances used on the electrical network.

The electrical inspection carried out when selling a house or flat is subject to a few specific conditions. If you want to sell a house whose electrical installation was put into service before 01 October 1981, you must have a compliance report. You must provide the new owner with the following documents

• The electrical inspection report, i.e. the electrical compliance certificate;
• The one-line diagram;
• The positional diagram;
• The EAN code.

If your property is not compliant, you can still proceed with the sale. However, the new owner will have to bring the installations up to standard and will have to carry out a compliance inspection. The selling owner is therefore obliged to provide an inspection certificate with the deed of sale. For this particular type of inspection, the seller must provide the date of sale to the authorised inspection body. Thus, the buyer will be obliged to bring the installation into compliance within one year.

The price of an electrical inspection in Brussels varies greatly because it depends on various factors. Indeed, the course of the electrical inspection and its price depend on the type of installation and the size of your electrical network. In addition, the cost of an electrical inspection also includes the payment and the intervention time of the electrician. On average, the inspection takes between 30 minutes and 1 hour. Thus, an electrical inspection generally costs between €150 and €200, not including any additional charges that may be applied by the electrician carrying out the inspection.

To be considered valid, your electrical certificate of conformity must be issued by a certified electrician. Only this specialist is able to assess whether your installation complies with current standards. If your electrical installation does not comply, they will not be able to issue your compliance report. In this case, you will have to take the necessary steps to put it back in order within a year of the inspection. You can then call your approved electrician again to obtain an electrical compliance certificate.

The period of validity of an electrical inspection in Brussels varies according to the type of installation:

• For installations for domestic use (flat, house): the report of the compulsory electrical inspection and the certificate of validity are valid for 25 years.
• For non-domestic installations: every 5 years for low-voltage electrical installations and every year for high-voltage installations.

In both cases, only an accredited body can validate the certificate of conformity issued by your electrician after his intervention.

The cost of a new electrical installation depends on several parameters that must be assessed at the start of the project.

The floor area is the first estimation criterion: a 45 m² studio requires fewer components and less working time than a 160 m² house, and the number of rooms, ceiling height and architectural features also influence the budget.

The level of specification you want plays a major role: an installation that only meets minimum legal requirements does not cost the same as one that includes home automation, custom LED lighting or built‑in USB sockets.

The initial condition of the property is another factor, since fully rewiring an old home where everything has to be redone is more expensive than working in a recent building, and constraints such as stone walls, vaulted ceilings or the absence of false ceilings make cable routing more complex and can increase the price.

You are not sure when to replace your electrical installation in Brussels? Be aware that postponing this decision can be dangerous. If you notice one or more of the following signs, you should act quickly and plan a full upgrade with CD Engineering, the Belgian reference for electrical interventions. Here are the key points to watch :

• The first is the age of your installation. Once it is more than 25 years old, the RGIE (General Regulations on Electrical Installations) requires that it be brought into compliance. Beyond this legal obligation, the system ages like any other equipment: cable insulation deteriorates, oxidation increases and traditional wire fuses are no longer up to modern standards.
• You should also be concerned if you still have two‑pin sockets without an earth connection in your home (no protective conductor).
• Another warning sign is circuit breakers that trip repeatedly, indicating that your installation is overloaded and can no longer power several devices at the same time.
• Certain situations call for an immediate full replacement of your electrical system. For example, you buy an older property and find an outdated electrical panel, you plan to add high‑consumption devices such as a heat pump or an electric vehicle charging station that exceed the capacity of your current installation, or you are completely renovating your interior with all walls open. All these scenarios mean a new electrical installation by CD Engineering is necessary.
