OPQIBI qualification (engineering) and RGE Études recognition
Voluntary in principle: no law requires an engineering firm to be qualified in order to trade. Several schemes make it unavoidable in the energy field, though. The mandatory energy audit for large companies requires, when outsourced, a qualification issued by an accredited body, under decree no. 2014-1393 and the order of 24 November 2014. The energy audit required when selling the least efficient dwellings, provided for by article L. 126-28-1 of the French construction and housing code, may only be carried out by a professional meeting qualification conditions — for a consulting engineer, OPQIBI qualifications 1905 or 1911. And since 1 January 2015, public energy-performance subsidies only fund studies and audits entrusted to providers holding "RGE Études" recognition.
Issued by: OPQIBI, the French engineering qualification body, a non-profit association founded in 1969 by the sector's professional organisations
Engineering organisations practising engineering as their main or secondary activity — technical design offices, engineering companies, consulting engineers, project managers, thermal engineers, acousticians, ecological engineers — in building, infrastructure, environment and energy performance. The qualification applies to the organisation, not to individuals.
What this scheme covers
- C.1A nomenclature of nearly two hundred numbered qualifications, organised by field (building, infrastructure, environment, energy), each described in a sheet setting out the service covered and the criteria to be met.
- C.2An award decided on a file reviewed by a qualification body, against three families of criteria: identification of the organisation (legal existence, tax and social-security compliance, insurance, financials), its human, material and methodological resources, and its references attested by clients.
- C.3"RGE Études" recognition attached to certain qualifications under the charter signed on 4 November 2013 with ADEME and the relevant ministries, a new version of which was signed on 27 May 2016. It adds specific requirements to the usual criteria: training and experience of technical referents, material and methodological resources, and a minimum number of references reviewed in detail.
- C.4A four-year cycle with annual checks: the qualification is granted for four years, but the certificate is reissued each year once the body has verified the organisation still meets the conditions. Organisations that cannot yet produce references enter through a probationary qualification, valid for one year and renewable once, to be converted into a full qualification thereafter.
The link with Qualiopi
Outside the scope of Qualiopi: OPQIBI qualifies engineering organisations, not training providers. The bridge runs both ways. Many design offices also sell training — building thermal performance, environmental regulations, audit methodology — and as soon as they want it funded from public or pooled funds, Qualiopi certification applies, regardless of their OPQIBI qualifications. Conversely, RGE Études recognition requires trained technical referents, hence training providers whose courses are recognised and which themselves need Qualiopi certification to be funded.
The process, summarised
- 1.Start from the services you actually deliver to select qualifications in the nomenclature, reading each sheet: service covered, resource criteria, expected references. A qualification requested without matching references weakens the whole file.
- 2.Submit the first-time application through the OPQIBI extranet, with its letter of undertaking and its sub-files: identification, resources, references.
- 3.Clear the admissibility check then the review: administrative, legal and financial verifications, checks with clients to validate the references, detailed analysis of at least one reference, then examination by the qualification body.
- 4.For RGE Études recognition, additionally evidence the initial and/or continuing training and experience of the technical referents, the material and methodological resources used, and a minimum number of references attested by the project owners.
- 5.Maintain the qualification through the cycle: annual check with updated documents and reissue of the certificate, then a renewal file at the four-year mark, backed by references from the period just ended.
FAQ — OPQIBI
+Is the OPQIBI qualification mandatory for a design office?
No: practising engineering requires no prior qualification. It does become decisive for certain specific assignments, though. The external provider of a mandatory energy audit must hold a qualification issued by an accredited body, and the energy audit required when selling the least efficient dwellings can only be performed, on the consulting-engineer side, by a qualified organisation. Add to that the eco-conditionality of subsidies: without RGE Études recognition, your clients lose access to public funding for your services.
+Which qualification should I apply for to carry out energy audits?
Two qualifications in the nomenclature cover building energy audits: 1905 covers energy audits of commercial buildings and/or multi-dwelling residential buildings, referenced against the requirements of the amended order of 24 November 2014; 1911 covers energy audits of single-family houses under article L. 126-28-1 of the construction and housing code. The choice depends on your target market, and the two can be held together.
+Why do recent certificates no longer mention Cofrac?
Company qualification bodies used to be accredited by Cofrac against the NF X50-091 standard. That accreditation lapsed on 30 June 2024 for regulatory qualifications, accreditation being reserved for bodies operating to European or international standards. Certificates issued since then no longer reference Cofrac, and an association, QUALICONFORM, was set up to assess qualification bodies' conformity with the NF X50-091 requirements. A recent certificate without a Cofrac reference is therefore normal.
