Answer: at the time of the sale of a property for an electrical installation of more than 15 years.
For several years, the electrical diagnosis has been compulsory at the time of the sale of a property, provided that the electrical installation has more than 15 years of seniority. This legal obligation does not apply during a simple change of tenant. The electrical diagnosis must imperatively be carried out by a professional of the sector, approved and independent. Be aware that other diagnostics are also mandatory when selling a home, by doing them all at the same time by the same company, you will save a lot of money. The electrical diagnosis alone costs around 100 to 250 € depending on the configuration of the accommodation: the larger it is, the more the price increases. The electrical diagnosis is valid for 3 years.Changing an electrical outlet Our practical DIY videos
