What is a French energy-renovation quote?
An energy-renovation quote is a pre-contractual act detailing all energy-efficiency works to perform, their price, duration and mobilisable aid. It is framed by several bodies of rules: (1) mandatory mentions for construction quotes (company identity, SIRET, RGE, decennial warranty, TTC price, works duration); (2) the French Consumer Code (art. L221-1+) requiring mention of the 14-day withdrawal right for off-premises sales (quote signed at the customer's home); (3) aid regulations (MaPrimeRénov', éco-PTZ, CEE) requiring specific information on action eligibility, contractor's RGE qualification and forecast bonus amount. The signed quote acts as a contractual commitment to perform the works under the agreed terms, and starts the withdrawal period.
Why sign the renovation quote electronically?
Identical legal force
Article 1366 of the French Civil Code recognises that electronic writing has the same probative force as paper writing. Nothing in the French Consumer Code or ANAH/CEE orders requires a handwritten signature — advanced signature (AES eIDAS) is explicitly accepted by financing bodies and civil courts.
14-day withdrawal timestamping
The 14-day withdrawal period (art. L221-18 French Consumer Code) runs from the day after signature for off-premises sales. Advanced signature precisely timestamps this moment, securing period computation and admitting procedure regularity against the customer.
10-year archiving + decennial warranty
The quote and paid invoice must be kept 10 years (decennial-warranty term, art. 1792 French Civil Code). Certyneo archives the signed quote + eIDAS audit trail for 10 years, accessible anytime for customer disputes or ANAH/DGCCRF audits.
eIDAS audit trail, court-admissible
Contractor + customer(s) identities, qualified timestamp, SHA-256 hash, SMS-OTP, IP geolocation. Admissible in customer disputes (unauthorised quote modification, exceeding announced price, RGE qualification defect), or in ANAH disputes (MaPrimeRénov' file regularity).

Frequently asked questions
- Can an energy-renovation quote be signed electronically?
- Yes, without restriction. Article 1366 of the French Civil Code grants electronic signatures the same value as handwritten ones. The DGCCRF, ANAH, CEE obligated parties and éco-PTZ partner banks accept quotes signed at advanced level (AES eIDAS) since 2021. Electronic signing is even recommended for its precise timestamping (withdrawal period).
- Does the 14-day withdrawal period apply?
- Yes for off-premises sales (signature at the customer's home) or distance sales (electronic remote signature) — articles L221-1+ French Consumer Code. The period runs from the day after signature. Advanced signature timestamps this date admissibly. For quotes signed at the contractor's office, the period does not apply (sale on premises).
- What are the mandatory mentions of a renovation quote?
- Full company identity (company name, SIRET, address, phone), RGE qualification (Qualibat, Qualit'EnR, Cequami number), decennial insurance (company, policy number), detailed works description (materials, brands, performance), HT and TTC prices per item, total HT/TTC amount, forecast duration, withdrawal-right mention, payment terms, warranties.
- What happens if the customer asks for modifications after signature?
- Any modification to the signed quote is subject to an amendment, itself signed by both parties. The amendment can be signed electronically with the same flow as the original quote. It restarts a 14-day withdrawal period if the modification is substantial. The eIDAS audit trail precisely traces each version of the quote and each amendment.
- Can the contractor charge for extra works not provided in the quote?
- No, except by express customer agreement materialised by an amendment signed before performance. Extra works billed without a signed amendment expose the contractor to a civil dispute (payment refusal) and a DGCCRF sanction (misleading commercial practice). Electronic signature lets an amendment be signed in minutes, even remotely.
- Does the signed quote constitute a firm commitment?
- Yes — a quote signed by both parties is legally a contract (art. 1101+ French Civil Code). The contractor commits to performing the works under the agreed terms; the customer commits to paying the agreed price. The 14-day withdrawal period (Consumer Code) allows the customer unilateral renunciation without motive; beyond, breach engages the failing party's liability.
- Can a multi-signer quote be signed for an indivision?
- Yes — in indivision (art. 815+ French Civil Code) or community between spouses, all co-owners must sign the quote on pain of partial nullity for works affecting the common property. Certyneo's multi-signer flow handles these setups with individual SMS-OTP — each indivisaire signs with their own phone number.
- Is the electronically signed quote admissible in disputes?
- Yes — advanced signature (AES) benefits from the reliability presumption of article 1367 of the French Civil Code. In civil-court disputes (customer refusing to pay, contractor refusing to perform, ANAH contesting regularity), the eIDAS proof PDF (identity, qualified timestamp, SHA-256 hash, SMS-OTP) constitutes admissible and recognised evidence.
