The money you're leaving on the table
45% of tertiary building directors don't leverage their CEE.* The system is perceived as complex — technical files, evolving sheets, processing timelines. Here's how to master it effectively.
Result: while your competitors finance 30-40% of their energy work through CEE, you pay 100% out of pocket.
Depuis janvier 2026, la période P6 des Certificats d'savings d'Énergie a bouleversé la donne : nouvelles fiches, montants renforcés, requirements tertiaires renforcées. C'est le moment de bouger.
Voici comment mobiliser vos CEE efficacement en 2026.
What exactly is P6? And why does it change the rules
CEE works by 5-year periods. P5 (2021-2025) is finished. P6 (2026-2030) begins with significant changes.
- Strengthened obligation for tertiary: Large tertiary surfaces must achieve 3.5% annual reduction (vs 2.5% in P5). This requires owners to undertake works.
- New standard operating forms: 12 forms were removed, 15 modified, 8 added. Amounts also change.
- Unit amounts noted for tertiary: La fiche LED BAT-EQ-127 passe de 0.80€ à 0.95€ par m² de lighting LED. La PAC passe de 80€ à 120€ par kWh.
- Strengthened controls: Non-compliant RGE files are rejected more strictly. No second chance.
Traduction : si vous aviez un project borderline en P5, il devient profitable en P6. Et si vous traîniez, c'est maintenant ou jamais.
Most cost-effective solutions for the tertiary sector in 2026
At Solyance, we sort the forms by net profitability added. Here are the most profitable:
Current CEE amount P6: 0.95€ per eligible m²
It's the simplest and most common project. Replacing old fluorescents with LED saves 10-20 kWh/m²/year. At 0.95€, a 5,000 m² LED project generates:
- Volume CEE : 5 000 m² × 0.95€ = 4 750€
- Investissement typique : 40 000€ TTC
- ROI direct : 12%
Common case: 10,000 m² building generates €9,500 CEE.
Montant CEE actuel P6 : variable selon surface et technologie
Installer une BMS (Gestion Technique du building) pour piloter heating/clim/lighting, c'est un économe de 10-15% sur la consumption énergétique globale. Les CEE valuent cela entre 1 500€ et 8 000€ selon votre système.
- Typical investment: 20,000 to 60,000€ all-in
- Estimated CEE bonus: 3,000 to 15,000€
- ROI: 15-30% over 5 years of operation
Typical case: 5,000 m² building with simple BMS = 6,000€ in CEE.
Current CEE amount P6: 25€ to 35€ per m² depending on thermal resistance
Isoler une roof tertiary, c'est 30-50 kWh/m² économisés par an. Coûteux mais très éligible CEE.
- Investment: 100 to 200€ ex-tax per m²
- Energy Savings Cert.: €25-35/m² (12-35% project financing)
- For 1,000 m²: 25,000 to 35,000€ CEE
Typical case: insulating 2,000 m² of roof = 50,000€ in CEE grants.
Current CEE amount P6: €120 per kWh cooling capacity
Installer une PAC pour remplacer un vieux climatiseur ou heating, c'est 40-60% de consumption heating/clim en moins.
- Investment: 500 to 1,500€ per kWh
- CEE bonus: 120€ per kWh
- For a 50 kWh heat pump: 6,000€ CEE
Typical case: 100 kWh heat pump for 3,000 m² building = 12,000€ in CEE.
Concrete figures: real multi-solution project example
To show you the cumulative impact, here's a real file we built in Q1 2026:
Works committed:
- Complete LED lighting: 8,500 m² — Form BAT-EQ-127
- New BMS (heating + controlled AC) — Form BAT-TH-116
- 75 kWh air-to-air heat pump for climate zone — Form PAC
- Isolation toiture 1 200 m² — Fiche BAT-EN-080
CEE amounts generated:
| Lever | Unit | P6 Tariff | Volume | CEE Grant |
|---|---|---|---|---|
| LED (BAT-EQ-127) | m² | 0.95€ | 8 500 | 8 075€ |
| GTB (BAT-TH-116) | flat-rate | 7 500€ | 1 | 7 500€ |
| PAC air-air | kWh | 120€ | 75 | 9 000€ |
| Isolation toiture | m² | 30€ | 1 200 | 36 000€ |
| TOTAL PRIME CEE | 60 575€ |
Impact financier :
- Investissement travaux total : 185 000€ TTC
- CEE Grant obtenue : 60 575€
- Remaining payment: 124,425€ (67% financing by the project owner)
- Net energy gain: 45% reduction in energy (heating + cooling + lighting)
This file was submitted at end of February 2026, validated by the certifying body mid-March. Grant paid in April.
The 3 essential vigilance points
Many project owners start work thinking CEE will come afterward. Major mistake. Mandatory rule : the CEE commitment must be signed BEFORE work starts. Past this stage: guaranteed rejection.
The rule: sign the CEE commitment first, works after. This is a 4-8 week delay between request and validation.
RGE = Reconnu Garant de l'Environnement. Les fiches CEE exigent que les travaux soient réalisés par une company certifiée RGE. Pas de RGE = pas de CEE, même si le travail est technique.
To do: before signer un quote, vérifier que l'company a le label RGE pour le domaine concerné (RGE-Efficacité énergétique, RGE-Énergies renouvelables, etc.).
P6 removed 12 sheets. If your file uses an outdated sheet, rejection. Also, the sheet must match precisely to your work. Relight part of the building and not all? The form only applies to the relit area.
To do: have your forms validated by an independent CEE expert before signing the quote.
Who can really handle your CEE file?
You have 3 options:
RGE companies often manage their own CEE files. It's quick — but biased : they optimize for their gain, not yours. They can inflate volumes or use sub-optimal forms to get you to sign quickly.
A CEE-specialized engineering firm prepares the file as agent. It's neutral, CEE gains go entirely to you. Costs €2,000-5,000 in setup fees but worth it for €40K+ in incentives.
That's what Solyance offers. We are certified CEE representatives. No conflicts.
If you have a dedicated person trained in CEE sheets and P6 regulations: possible. But rare and time-consuming. One mistake = loss of €30-60K.
Our advice: if CEE > €20,000, use independent third party. It's a profitability guarantee.
Foire aux questions
Yes, but with a cap: total grants cannot exceed 90% of investment. Example: if you have 30K€ in CEE, 10K€ in MaPrimeRénov' and 20K€ in regional subsidy, total (60K€) can't exceed 90% of 70K€ investment (= 63K€ max). Beyond that, aids reduce proportionally.
Non, la fiche PV n'existe qu'en entreprises agricoles (filière spéciale). Pour du PV tertiary, pas de CEE. Par contre, les gains d'autoconsommation PV + LED et BMS couplées peuvent générer des CEE. C'est un arbitrage : si vous faites PV + LED, les CEE viennent du LED, pas du PV.
Count 6 to 12 weeks Total: 4-6 weeks to validate commitment, 2-4 weeks for post-work follow-up (inspection visit), 2 weeks for payment. In P6, timelines are stricter but decisions faster. Plan: file in February = money in April/May.
The certifying body (ATEE, Ecocert, etc.), based on the sheets and actual volumes. You submit an estimated request, the inspector verifies on-site and adjusts. Most of the time, final amount = estimated amount ±5%. Gaps >10% are rare unless the work doesn't match the sheet.
Your 2026 CEE file awaits
Depuis janvier, la période P6 a augmenté les montants et resserré les contrôles. C'est le moment de capitaliser sur les nouvelles fiches before que la concurrence ne le fasse. Nous auditions vos bâtiments, identifions every solution d'saving, et montez votre dossier de A à Z.
