Indices, fields, marks: how to read a Qualifelec certificate

A logo on a quote tells you almost nothing. The certificate does — provided you know how to read it. On a Qualifelec document four pieces of information sit on top of one another, and each answers a different question: what type of works, at what level of involvement, with what extra requirements, at what company scale. Here is the decoding, useful both for calibrating your own application and for checking what a competitor or a subcontractor advertises.

The field: which works

That is the first useful line. Qualifelec qualifications cover the whole span of electrical, energy and digital engineering trades, split into fields: high-voltage electrical installations, electric HVAC (heating, ventilation, air conditioning), connections and networks, connected buildings, public lighting, low-voltage systems, maintenance of electrical installations, aerials. Specialised qualifications sit alongside these, including the one covering electric-vehicle charging infrastructure.

Several fields are themselves split according to the scale of the building served — housing, retail and small commercial premises on one side; medium and large commercial premises and industry on the other. This split is not decorative: the constraints of a detached house and those of an industrial site have little in common, and a qualification obtained for one says nothing about capability on the other.

On the certificate, qualifications appear both in abbreviated form and written out in full. That is a convenience with real consequences: a buyer who is not from the trade reads the long wording, not the code.

The index: how early you intervene

The index is the most misunderstood item. Three levels structure the reading:

Level	What the company does	What it implies
Execution	Carries out works from a supplied design package	Execution skills, site supervision
Design and execution	Produces the execution drawings, then builds	In-house calculation and sizing capability
Conception, design and execution	Devises the solution, designs it and implements it	Full engineering, responsibility for the concept

The classic mistake is to read this as a value scale and aim for the top. That is a bad calculation in both directions. Claiming conception without producing conception references leads to a downgraded award or a refusal. Conversely, settling for an execution level when your in-house design office genuinely sizes the installations shuts you out of tenders for four years.

One special case: the probationary index. Companies starting out — and therefore with no references to produce — can enter the scheme this way, on a shorter cycle than the standard four years. This is the mechanism that keeps a new firm, often set up by an experienced professional, from spending two years locked out of qualified tenders while it builds a track record. Some fields, such as maintenance, also have their own index scales.

Marks: the extra requirements

A mark never exists on its own: it attaches to a qualification already held. The best known is the RGE mark — « Reconnu Garant de l’Environnement », the French quality sign for energy-renovation work — which attests compliance with additional requirements covering energy-saving and renewable-energy works: a trained technical referent, and audits of completed projects.

This is where most commercial misunderstandings arise. “Being RGE” is not a qualification in itself: it is an extra tier placed on a specific qualification, for a specific field of works. A company can therefore be RGE for one type of works and not for another it also carries out. When a customer asks whether you are RGE, the right answer is always “RGE for which works?”.

The qualification covering electric-vehicle charging infrastructure follows yet another logic: above a certain power threshold it is a regulatory obligation. We cover it in our article on the IRVE qualification.

Classification: at what scale

Last item: the classification situates the company in terms of size and capacity, based on elements such as headcount and completed projects. It answers a question buyers ask themselves without always spelling it out: does this company have the standing for a project of this size?

It is the line that prevents misunderstandings in both directions — an undersized firm committed to too heavy a project, or a solid SME left out of a tender for want of being able to prove its scale.

What a certificate does not tell you

Three limits are worth knowing.

A certificate has a date. During the four-year cycle a certificate is issued each year, once the body has checked the company still meets the conditions. A three-year-old certificate therefore does not prove the qualification is still in force: ask for the current year’s certificate.

A certificate no longer mentions Cofrac. Accreditation of qualification bodies based on the NF X50-091 standard lapsed on 30 June 2024 for regulatory qualifications. Certificates issued since then no longer carry that reference, and the recognition framework for these bodies is evolving. A recent certificate without an accreditation logo is nothing to worry about.

A certificate is not an audit of your projects. A qualification is granted on file: resources, references, administrative compliance. It attests capability, not the quality of any particular project. The RGE mark is the only element that introduces a check in the field, through completed-works audits.

Why these signals work anyway

Quality-management research has long asked whether a quality sign issued by a third party changes anything measurable. A meta-analysis by Basak Manders, Henk J. de Vries and Knut Blind, presented in 2013 in the Academy of Management Proceedings, aggregates 92 studies on ISO 9001 certification and concludes that the overall effect on certified firms’ financial performance is positive, with substantial variation by sector and company size (reference).

Company qualification does not work through the same mechanism as system certification, but the transferable lesson is the same: the value of a sign lies in the credibility of what it attests, not in its presence on a letterhead. Hence the point of reading the four lines of a certificate rather than remembering the logo.

Take action

Pull out your company’s latest Qualifelec certificate — or that of a subcontractor you engage — and read it line by line: field, index, marks, classification, date. In five minutes you will know what it actually covers and what to request at the next cycle. The full scheme sheet, with the steps and the follow-up calendar, is here: the Qualifelec qualification.
