The real estate renovation market is undergoing a phase of regulatory restructuring that directly alters the criteria for selecting a renovation company. Public aid is refocusing on comprehensive renovations, the RGE certification is evolving, and the failures of construction companies remain at a high level. In this context, choosing a reliable provider requires verifying elements that most guides overlook.
Comprehensive renovation and CEE aids: what the regulatory refocus changes for provider selection
Since 2026, a decree has refocused the Energy Savings Certificates (CEE) on coherent comprehensive renovations rather than isolated works. Gone is the single action (sole insulation or sole boiler replacement) as the main lever for aid: projects must now rely on a mandatory energy audit with a work scenario and post-work performance verification.
This shift has a direct consequence on the type of company to prioritize. A structure capable of managing a bundle of works (combined envelope and systems) has a concrete advantage over a craftsman specialized in a single lot. The ability to produce or coordinate a serious energy audit becomes a sorting criterion, not a bonus.
Field feedback diverges on this point: some companies claim expertise in comprehensive renovation without having the teams to carry it out. Verifying completed projects, requesting completion certificates, and post-work audit results allows for distinguishing between rhetoric and practice. Among the tools that facilitate this comparison work, the agorenovation comparison on Maisonisor lists companies according to their actual intervention scope.
RGE obligation and subcontracting: the rule coming into effect in 2027
Starting January 1, 2027, the company invoicing the work must itself hold the RGE certification. Until now, a common setup involved having the invoicing done by an RGE-certified company that subcontracted the execution to non-certified artisans. This scheme has fueled fraudulent practices documented by several organizations.
The decree published in August 2026 aims to put an end to this gray area. For individuals comparing quotes, verification is theoretically simplified: the company signing the quote must appear in the official RGE directory for the type of work concerned.
Points of vigilance regarding RGE certification
The RGE certification is not a universal quality label. It covers specific areas (insulation, heating, ventilation, renewable energies). An RGE-certified company in insulation is not necessarily qualified to install a heat pump.
- Check the exact area of RGE certification in the official directory, not just the mention “RGE company” on the provider’s website.
- Ask for the validity date of the certification: it is renewed periodically and may expire between the signing of the quote and the start of the work.
- Confirm that the company will directly invoice the work, without the interposition of a non-certified third-party structure.
Financial health and construction company failures: an underestimated risk
The available data on company failures in the renovation sector shows that the risk of business cessation during the project remains significant. A project interrupted due to the provider’s judicial liquidation leads to additional costs and delays that are difficult to absorb, especially when deposits have already been paid.
Consulting a company’s financial statements before signing a quote is not a common reflex among individuals. However, the data is accessible on legal publication sites and commercial court registries.
Warning signs to spot before signing
Beyond the financial statement, certain concrete indicators deserve attention during the consultation phase.
- An abnormally low quote compared to other proposals received may signal a struggling company trying to fill its order book at any cost.
- Very short start times (a few days) where established companies show several weeks of waiting.
- The absence of verifiable ten-year insurance or an insurance policy number that does not correspond to the company signing the quote.
- A recent registered office (less than two years) combined with the absence of documented reference projects.
Reading a renovation quote: the lines that protect the project owner
A renovation quote that fits on one page is rarely a good sign. An actionable quote details each lot with supplies, labor, and payment conditions. The mention “renovation works – global package” does not allow for comparison with a competitor, nor for contesting a subsequent defect.
The items to watch vary according to the nature of the project. In energy renovation, the quote must specify the targeted thermal performance (thermal resistance for insulation, performance coefficient for heating). This data conditions eligibility for aid and serves as a reference in case of disputes.
Payment conditions and deposits
The payment schedule is a protective lever often overlooked. A deposit exceeding one-third of the total amount before any work starts exposes the project owner in case of failure. The conditions for retaining guarantees (generally a few percent of the total amount, kept until the lifting of reservations) must be clearly stated.
The acceptance of the work, formalized by a contradictory report, triggers legal guarantees. Without a signed acceptance report, asserting the ten-year guarantee becomes legally complex. This document, often omitted on small projects, remains the key piece in case of defects found after delivery.
The choice of a renovation company relies less on commercial promises than on precise documentary verifications: RGE certification in the correct area, active ten-year insurance, consultable financial statements, detailed quotes lot by lot. The regulation coming into effect in 2027 regarding RGE subcontracting will simplify part of this work, but until then, the burden of verification rests on the project owner.
