Certification of French property diagnosticians (technical survey operators)
Mandatory: the surveys making up the technical diagnostic file handed over on a sale or a letting may only be produced by an individual whose competences have been certified by an accredited body. Certification is obtained domain by domain and is valid for seven years.
Issued by: Personnel certification bodies accredited by Cofrac, within the framework set by the French housing ministry (construction and housing code, article L. 271-6)
Self-employed and salaried property diagnosticians, building technicians retraining into the trade, and — on the other side — the organisations that train them, which face regulatory requirements of their own.
What this scheme covers
- C.1Six separate certification domains: energy performance (DPE), asbestos, lead (lead exposure risk report), termites, internal gas installation condition and internal electrical installation condition. Each domain is taken and renewed separately.
- C.2“With mention” certifications for asbestos and lead, which unlock the most technical assignments (pre-works or pre-demolition surveys, complex buildings) and involve heightened requirements.
- C.3A structured seven-year cycle: mandatory prior training, theory and practical entry exams, then monitoring by the certification body during the cycle (documentary checks, on-site inspection) and continuing training, before a recertification exam.
- C.4Personal obligations inseparable from certification: insurance covering liability arising from assignments, and no link liable to compromise impartiality and independence towards the owner, their agent or any firm that might carry out the works.
- C.5Public traceability: holders of a valid certification appear in the official register of certified diagnosticians maintained by the administration, with their domains and certification body.
The link with Qualiopi
Outside the scope of Qualiopi: this is a personnel certification grounded in the construction and housing code, not a training-provider certification. The bridge is direct on the training side — organisations preparing candidates for diagnostician certifications must meet the requirements set by the “competence” orders, and, if they want their courses funded from public or pooled funds, must be registered training providers holding Qualiopi.
The process, summarised
- 1.Check the prerequisites for the target domains with an accredited certification body: the orders in force condition access on a level of education or on professional experience in construction.
- 2.Complete the domain's mandatory prior training with a provider meeting the regulatory requirements — longer for “with mention” certifications.
- 3.Sit the theory exam then the practical exam with the certification body, domain by domain.
- 4.Before the first assignment: take out the required professional liability insurance and secure independence from clients and contracting firms.
- 5.Sustain the cycle: respond to the certification body's monitoring checks, follow the required continuing training, then sit the recertification exam before the seven-year deadline.
FAQ — Property diagnostician certification
+Can you produce a DPE without being certified?
No. The construction and housing code requires using an individual whose competences have been certified by an accredited body, or a company employing such professionals. A survey produced without valid certification does not carry the expected value and exposes both its author and the client.
+Is there one certification per survey type or a single one for everything?
One per domain. A diagnostician wanting to offer the full technical diagnostic file must hold certifications in all six domains, each with its own exams, monitoring and expiry date. That is why retraining paths are spread over time.
+Is the regulatory framework for this certification stable?
It has moved a great deal. The order of 24 December 2021 was annulled by the Conseil d'État, with effect deferred to 1 September 2024, and replaced for asbestos, electricity, gas, lead and termites by the order of 1 July 2024; the DPE falls under the order of 20 July 2023. The scheme is regularly litigated: before committing, check which texts are in force on the day you act.
