The latter has a very important role in detecting any unfortunate leakage of current to earth and also in stopping the power supply as soon as the leakage current reaches the differential value corresponding to the leakage, for example: 500 milliamperes (500 mA).
  3. The real estate diagnostician checks for the presence of a device electrical overcurrent protection which will be necessary to avoid overheating and fires.
  4. The property diagnostician checks the presence of an electrical installation adapted to wet rooms. He measures the equipotential bonding between the various elements that could cause electrification in the event of direct contact.
  5. The property diagnostician Checks the condition of cables, connectors, electrical switches...to summarise all the electrical equipment and points out if they are old, unsuitable for use and could be a danger to the inhabitants.

He usually takes between 30 minutes and 2 hours depending on the size of your home.

How long is the electricity diagnosis valid?


  • RentalThe diagnosis has a validity of 6 years from the date of its completion, so if your tenant leaves the premises after this 6-year period, you will have to carry out a new electricity diagnosis before re-letting your property.
    However, if your tenant leaves the premises before the 6 year period, you can re-let your property without having to carry out a new electricity diagnosis.
  • SaleThe diagnosis has a validity of 3 years from the date of its completion.

  • The amount of the rent or the sale price of the property may be reduced.

Sale of property and non-compliant electricity diagnosis: who should pay for the work to bring it up to standard?


Bringing the electrical installation up to standard

In the event of anomalies or malfunctions found in the electrical system, the law requires that the work be brought into conformity. This work can be carried out either by the seller, who will have the work done at his expense before the sale, or by the buyer, who will have the work done at his expense.

This is an agreement that will be specified on the promise to sell the property concerned.

If the seller does not wish to carry out this work, the potential buyer will be able to request a reduction in the sale price.
