Fee-paid, commission-free energy advice across solar, storage, heat pumps, ventilation, and hot water — structured around your home and your goals, not around a product sale.
The process starts with your real data. Analysis of your past 12 months of EDF/Enedis consumption to understand your base-load, peak usage, seasonal variation, and opportunities for load-shifting. This ensures any system is sized around your lifestyle and your property, not generic assumptions or an installer's preferred range.
The service now covers the full thermal and electrical picture: heat pump sizing and MaPrimeRénov' grant navigation, MVHR ventilation compliance, thermodynamic hot water specification, solar and battery concept design, and independent quote review. Each service is scoped and fee-paid. None carries a commission, referral fee, or financial tie to any installer or supplier.
The result is a requirements-led specification, not a sales quote. You receive a clear, engineering-driven recommendation and a detailed technical specification that any RGE-certified installer can price against — ensuring like-for-like quotes, fair comparisons, and a system that genuinely meets your needs.
My only priority is that you make an informed, confident decision based on accurate analysis, transparent modelling, and independent advice.
The Home Energy Autonomy Assessment is the umbrella service — a whole-home strategy that draws on one or more of the four technical assessments below depending on your property's needs. Each technical assessment can be commissioned as part of a full HEAA, or as a standalone service where the scope is already clear.
Before any conversation about heat pumps, solar, or grants, it helps to know exactly where your electricity is going — and whether that matches what you'd expect. Every on-site visit starts with a full appliance-by-appliance audit of your property, cross-checked against a full year of your actual EDF billing data, so the figures aren't guesswork.
Included with every on-site visit — no separate feeThe starting point for most clients. A structured review of your property's energy position — consumption, heating sources, solar yield, battery sizing, and grant eligibility — producing a full written report you keep and use independently.
On-site (Dordogne & Nouvelle Aquitaine) or remote desktopIndependent heat load study and MaPrimeRénov' grant navigation for ASHP and GSHP — the highest-value grant available in 2026, correctly sized before you approach any installer. EN 12831-compliant methodology.
Independent specification for chauffe-eau thermodynamique systems — correctly sized for your household, positioned for maximum efficiency, and grant-optimised before you approach any supplier. One of the simplest standalone MaPrimeRénov' measures.
RE2020 and NF DTU 68.3 compliant ventilation assessment — producing the airflow schedule, unit specification, and MaPrimeRénov' dossier your contractor needs. Essential for any renovation requiring a compliant ventilation strategy.
A technical concept brief — string layout, inverter sizing, battery chemistry, and Enedis guidance — sized for your actual consumption, not a standard template. Funded via the prime à l'autoconsommation, separately from MaPrimeRénov'.
Already have installer quotes? An independent line-by-line review — checking specs, RGE certification, grant compliance, and contract terms — before you sign anything. Owner-side project support through to Consuel also available.
An independent eye on your installed system every month — translating monitoring data into plain English, flagging underperformance, and confirming your system is delivering what it promised. Available to existing clients in a future phase.
All fees are time-based and quoted HT. The initial conversation is always free. No commissions, no installer relationships — the fee paid by you is the only remuneration.
