What is a CEE mandate?
Energy-Savings Certificates (Certificats d'Économie d'Énergie, CEE), created by the POPE Act n° 2005-781 of 13 July 2005 and codified at articles L221-1 and following of the French Energy Code, are a scheme requiring energy suppliers (the "obligated parties": TotalEnergies, EDF, Engie, fuel sellers, fuel oil / LPG sellers) to promote and finance energy-saving works for households and businesses. A homeowner carrying out an eligible action (insulation, heat pump, biomass boiler, energy audit) can assign their CEE right to an obligated party or to a delegate (Hellio, Effy, Sonergia, etc.) in exchange for a CEE bonus ("coup de pouce") paid before or after the works. The CEE mandate is the legal act formalising this assignment and the authorisation given to the delegate to prepare the file and collect the CEEs.
Why sign the CEE mandate electronically?
Accepted by all obligated parties since 2020
The main CEE obligated parties and delegates (TotalEnergies, EDF, Engie, Hellio, Effy, Sonergia, ENI, etc.) explicitly accept mandates signed with eIDAS advanced signature (AES) since 2020. The French Directorate-General for Energy and Climate (DGEC) confirmed in 2022 the full validity of CEEs filed with electronic mandates.
Multi-signer obligated party + beneficiary + contractor
The CEE flow involves at minimum the beneficiary and the delegate (obligated party or delegate). In practice, the RGE contractor must also co-sign to take responsibility for the action's compliance. Our multi-signer flow handles 3+ signers with individual SMS-OTP.
6-year archiving + national CEE audit
CEEs are auditable 6 years after filing (art. R221-1 Energy Code). The national CEE office (Lyon) can demand the signed mandate, the quote, the invoice, the sworn statement and the works-acceptance report. Certyneo archives the mandate for 10 years (beyond the CEE audit window) with eIDAS audit trail.
eIDAS audit trail, court-admissible
Every mandate is delivered with a proof PDF: beneficiary + delegate + contractor identities, qualified timestamp, SHA-256 hash, SMS-OTP. Admissible in CEE-office disputes (fraud, ineligible action, non-RGE subcontracting, illegal canvassing banned by the 24 July 2020 Act).
Sign a CEE mandate in 4 steps
From the RGE quote to CEE valuation at the obligated party, in under 5 minutes for signing.
1. Prepare the mandate
Upload your template or start from a compliant one: identity of beneficiary + CEE obligated party/delegate + RGE contractor, eligible action (standardised operation fiche, e.g. BAR-EN-101 attic insulation), forecast CEE bonus amount in €/MWh cumac.
2. Add signers
Beneficiary + CEE delegate (obligated party or delegate) + RGE contractor. For a co-ownership, add the property manager. Each receives a secure personalised link by email.
3. Choose the eIDAS level
Advanced signature (AES) accepted by all CEE obligated parties: identity verification by SMS-OTP, unique per-signer certificate, qualified timestamp. Compliant with article 26 of the eIDAS Regulation.
4. Sign and file at the CEE office
Each signer signs from their phone. The mandate attaches to the CEE filing made by the obligated party/delegate on the Emmy registry, and is archived 10 years with its proof PDF.
Frequently asked questions
- Can a CEE mandate be signed electronically?
- Yes — all CEE obligated parties (TotalEnergies, EDF, Engie, ENI) and main delegates (Hellio, Effy, Sonergia, GEO PLC) accept mandates signed with eIDAS advanced signature (AES) since 2020. Article 1366 of the French Civil Code grants full probative force. The national CEE office accepts AES mandates on audit.
- What is a MWh cumac?
- MWh cumac (cumulated + discounted) is the CEE unit of measure. Insulating 100 m² of attic, for example, generates 60,000 kWh cumac (value of fiche BAR-EN-101). The CEE bonus paid to the beneficiary depends on the market price of the MWh cumac (~€7-9 per MWh cumac in 2026, varying by obligated party and government boost schemes).
- Who can be a CEE delegate?
- Two categories: (1) direct obligated parties (TotalEnergies, EDF, Engie, ENI, fuel sellers > 7 GWh/year); (2) CEE delegates agreed by obligated parties (Hellio, Effy, Sonergia, Capital Énergy, GEO PLC, etc.). Since the 24 July 2020 Act, cold-calling is banned for CEEs — the mandate must be signed without unsolicited canvassing.
- Is the beneficiary paid before or after the works?
- It depends on the scheme and the obligated party. CEE "boosts" (heating, insulation) often include a quote-stage advance (bonus directly deducted from the quote by the contractor, reducing the balance). Classic CEEs are paid after works completion, on production of the paid invoice and the signed sworn statement.
- Which actions are CEE-eligible?
- Over 200 standardised operation fiches (FOST) covering insulation (BAR-EN-101 to 109), heating (BAR-TH-104+: heat pumps, biomass boilers), ventilation (BAR-TH-127: dual-flow VMC), energy audit (BAR-TH-164), co-ownership works, industry, tertiary and transport. Fiches are published in the BOAMP and on calculateur.ademe.fr.
- Can CEE be combined with MaPrimeRénov'?
- Yes — CEE + MaPrimeRénov' combination is encouraged by the state on most actions (insulation, low-carbon heating, audit). Watch out for capping: MPR + CEE cannot exceed 90% of works TTC for modest households (100% for very modest). A tri-aid mandate (MPR + ANAH + CEE) bundles these efficiently.
- What happens in case of CEE fraud?
- The national CEE office (Lyon) can, after audit, cancel issued CEEs and demand their return to the obligated party. Sanctions can include full bonus reimbursement, administrative fines (up to €10,000) and criminal proceedings for fraud (art. 313-1 French Penal Code). The eIDAS audit trail produced by Certyneo identifies the at-fault signer.
- Is the CEE mandate admissible to the national CEE office on audit?
- Yes — advanced signature (AES) benefits from the reliability presumption of article 1367 of the French Civil Code. The national CEE office accepts the AES mandate + audit trail (eIDAS proof PDF) on the same footing as a paper mandate, provided signers are identifiable and the document is intact.
