What is RGE certification and why does it matter?

If you've been looking into energy grants in France (whether for a heat pump, insulation, or solar panels), you'll have encountered the letters RGE. It comes up on contractor websites, in grant application forms, and in the small print of MaPrimeRenov' guidance. This guide explains what it is, why it was created, what it actually certifies, and what it doesn't.

What RGE stands for

RGE stands for Reconnu Garant de l'Environnement, which translates as Recognised Guarantor of the Environment. It's a label applied to contractors who have obtained specific certifications covering energy-efficiency work. The scheme was created by the French government to address a problem: subsidy programmes were funding work that wasn't being done properly, and there was no reliable way to distinguish competent contractors from incompetent ones.

RGE was introduced as a baseline requirement. To access grants, homeowners must use certified contractors. To become certified, contractors must complete training, pass assessments, and submit to audits. The theory was that this would raise the standard of work and reduce fraud.

In practice, RGE has improved the situation. It's not perfect (we'll come to what it doesn't guarantee), but it created a register you can actually check, and it gave homeowners a lever: if a contractor isn't on the register, you can walk away.

Why France created it

Before RGE, France's energy subsidy programmes had a fraud problem. Some contractors were submitting grant applications for work that was never done, or done to a poor standard. Others were using unqualified subcontractors. The subsidy money was flowing without any quality control. RGE was the government's response: tie the subsidy to a contractor qualification, and create a public register so that anyone could verify before committing.

The scheme is managed by accreditation bodies approved by the state: Qualit'EnR, Qualifelec, Qualibat, and others. They carry out the assessments and maintain the records.

The different RGE qualifications

RGE is not one single certification. It's an umbrella covering a range of trade-specific qualifications. The most relevant ones for residential energy work are:

• QualiPAC: heat pump installation, both air-source and ground-source
• QualiPV: photovoltaic solar panel installation
• QualiSOL: solar thermal installation (water heaters)
• Qualisol+PAC: combined qualification for solar thermal and heat pumps
• QUALIFELEC: electrical works, including heating systems, EV charging, and certain renewable installations
• Qualibat RGE: building fabric work, primarily insulation
• Eco-Artisan: a broader certification that can cover multiple trades for smaller contractors

Each qualification applies to a specific type of work. A contractor certified under QualiPAC is qualified to install heat pumps but is not automatically certified for insulation work. If you want both a heat pump and wall insulation done as part of the same renovation, you need to check that the contractor holds the relevant qualification for each type of work, or that you have separate contractors for each.

This matters when you are planning a grant application. If you submit a MaPrimeRenov' claim for insulation carried out by a contractor who only holds QualiPAC, the application will be rejected.

How to verify a contractor's RGE status

The official register is at qualirenovation.fr. You can search by contractor name, their SIRET number (French company registration number), postcode, or certification type. The search is free and public.

When you find a contractor in the register, check two things:

1. That the certification is currently valid (look at the expiry date)
2. That the specific qualification matches the type of work on the quote you've received

Don't rely on the certification printed on the contractor's letterhead, their website badge, or what they tell you in conversation. Certifications expire, and not all contractors update their marketing materials when they do. The register is the authoritative source.

What RGE actually certifies, and what it doesn't

This is the part that catches people out. RGE is a compliance certification, not a quality endorsement.

To obtain RGE, a contractor must: complete the required training for their qualification category; pass a theoretical assessment; demonstrate that they have experience in the relevant type of work; and submit to a periodic audit by the certifying body. The audit typically involves reviewing documentation, not inspecting actual job sites in detail.

What RGE does not mean: that someone has reviewed this contractor's specific work and judged it to be excellent. There is no inspector visiting installations and grading the quality. The certification establishes that the contractor has the knowledge and has met the administrative requirements of the scheme.

In short: RGE tells you the contractor meets a minimum standard. It does not tell you they are the best at what they do, or that they won't cut corners. For that, you need to do your own due diligence: ask for references from previous clients, check that they carry the required decennale liability insurance, and get multiple quotes so you can compare what's being proposed.

Renewal and what happens when it lapses

RGE certifications must be renewed periodically. Most qualifications run for four years, with a mid-term audit carried out around the two-year mark. If a contractor fails to renew, or fails the mid-term audit, their certification lapses and they are removed from the active register.

Some databases and listing sites show contractors even after their certification has expired. The qualirenovation.fr register is the one that matters: if a contractor is not listed there with a current certification, they are not RGE for grant purposes, whatever their own materials say.

What happens if you use a non-RGE contractor

If you hire a contractor without the relevant RGE certification and then try to claim MaPrimeRenov' or CEE, the application will be rejected. The work itself is not illegal. No fine applies to you as the homeowner. But you will lose the subsidy entitlement for that project, and you cannot redo the work to claim it retrospectively.

For higher-income households where the grants are smaller, this might be a minor financial consequence. For lower-income band households where grants can cover a substantial portion of costs, losing eligibility on a significant installation could mean forgoing several thousand euros. That's the practical cost of not checking before signing the devis.

Practical advice for English speakers

Before you sign any devis for energy work, go to qualirenovation.fr and search for the contractor. It takes two minutes. If they're not listed, ask them to explain. Sometimes contractors work under a parent company or group that holds the certification: this is legitimate, but you need to verify it on the register, not take their word for it.

When collecting multiple quotes, note each contractor's RGE number and check them all. It's a straightforward comparison point: all things being equal, a currently certified contractor is preferable to one who says certification is "in progress" or "being renewed."
