Construction sector: Essential steps for verifying building professionals

Selecting qualified construction professionals is a critical step in home renovation projects to ensure quality and avoid financial loss. Consumers are advised to clearly define their needs, create detailed work lists, and compare multiple quotes to ensure accuracy in materials, timelines, and methods.

In France, vigilance is increasingly necessary due to a rise in reported fraud. In 2024, the DGCCRF recorded over 44,000 reports via SignalConso regarding the real estate and construction sectors, with more than 26,000 specifically related to energy renovation. To mitigate risks, it is essential to independently verify a contractor's legal existence using their SIRET number through official registries like INSEE, and to demand up-to-date proof of civil liability and ten-year guarantee insurance before signing any contracts.
