Electricity inspection

Electricity inspection

In Belgium, an electricity inspection is compulsory:

  • When commissioning a new installation
  • Whe extending or modifying an installation
  • Every 25 years for existing installations.

You must be able to hand over a valid inspection certificate when selling or renting out a property.

The instructions given below are only intended for electrical household installation.

Electrical household installations are low-voltage installations (230-400V) in buildings for residential use, such as houses, flats, studio, appartments, assisted-living flat and small businesses (under certain conditions).

When is an inspection compulsory ?

  • When commissioning a new installation and/or after major changes to an existing installation (for example, adding a new circuit): an investigation of conformity is compulsory before commissioning (AREI art. 270).
  • When selling residential accommodation: installations from before 01/10/1981 (AREI art. 276bis) and installations after 01/10/1981 (AREI art. 271).
  • Periodic inspections every 25 years (AREI art. 271).
  • When the connected grid load is increased: installations before 01/10/1981 (AREI art.276) and installations after 01/10/1981 (AREI art. 271).

Which documents do you have to hand over during the inspection ? ?

In order to avoid us having to return at a later time, you must hand over to us the single-line diagram and the electrical arrangement drawing (which must show the exact location of the switch panels, junction boxes, distribution boxes, plug sockets, switches and lights, washing machine, cooker, etc.).

  • If you do not have these diagrams at your disposal, the expert must specify a violation on his report. This has no consequences for the sale of your property. It only has consequences for the provision of information. If the report does not meet the requirements, you are responsible for ensuring the necessary adjustments are made within the legally set time period.
  • For electrical installations commissioned after 1st October 1981, we recommend that you have these diagrams drawn up by an electrician.
  • For electricity installations commissioned before 1st October 1981, our inspection expert has the responsibility to draw up a simplified electrical arrangement drawing and produce a concise description of the switch panel. That will be done free of charge! Although they are compulsory, these drawings do not replace the diagrams mentioned above.

What happens during an electricity inspection ?

  • Our inspection expert first asks for your electricity file (the previous report, if you have one, the single-line diagram and the electrical arrangement drawing). Next, he gathers information about the owner, the manager or the user of the installation, and the engineer who is responsible for maintaining the installation.
  • The meter readings are also recorded. Please have the name of your grid operator and the EAN code (starts with 54) available. This information can be found on your annual energy bill or on any of the intermediate invoices.
  • The inspection expert then checks whether the diagrams are in order and whether they correctly represent the actual situation. He also checks the switch panel (which must be easily accessible) and the entire electrical installation, part by part. To do this, he requires access to the whole property, including the basement (also when inspecting a flat).
  • After this inspection, it is determined whether your electrical installation meets the General Regulations for Electrical Installations (AREI).

What do we check ?

  • The single-line diagram and the electrical arrangement drawing of the electrical installation. The diagrams must be available on site.
  • The earth resistance.
  • The general level of insulation.
  • The presence of differential current devices (earth leakage circuit breakers).
  • The distribution panels, the electric cables, the plug sockets and the switches.
  • Whether the installation meets the AREI regulations.
  • The continuity of the protective conductors for the plug sockets.
  • The protective measures against touching live components, either directly or indirectly.
  • The protective measures against current surges and short-circuiting.
  • ...etc etc
