French home energy terms explained in plain English
Contractors write their quotes in French. Official subsidy forms use abbreviations. Inspectors quote regulations by number. If you're an English speaker trying to understand what's actually being proposed, this glossary is a reference you can come back to. Each entry explains what the term means, why it matters, and what to do about it.
A
- ABF: Architecte des Bâtiments de France, the state architect who reviews building work near listed monuments and can make planning approval binding on the mairie (town hall)
- ADVENIR: the EV charging subsidy programme for collective housing and public locations; does not apply to individual houses
- ANAH: Agence Nationale de l'Habitat; the public body that administers MaPrimeRénov' (the state renovation grant) and other housing improvement programmes
- Audit énergétique: a detailed energy assessment, deeper than a DPE (energy performance certificate); required when selling an E, F or G-rated house and for MaPrimeRénov' rénovation d'ampleur
- Auto-consommation: self-consumption of solar electricity; what it means and how the French system works
C
- CEE: Certificats d'Économies d'Énergie; the energy supplier subsidy scheme, open to second homes, that runs alongside MaPrimeRénov'
- CESI: chauffe-eau solaire individuel, a solar water heater; the Côte d'Azur gets the highest CEE band for it, and MaPrimeRénov' now funds it only inside a whole-house renovation
- CONSUEL: the body that inspects electrical installations in France; its attestation is required for a new installation, a full rewire or solar panels before Enedis (the grid operator) connects them
- COP / SCOP: heat pump efficiency ratings; COP is the instantaneous ratio of heat output to electricity input, SCOP is the seasonal average used to estimate annual running costs
- Copropriété: shared ownership of a building or estate; what the syndic (the building's managing agent) and the yearly AG (the owners' general meeting) decide, and which work needs an owners' vote
D
- Déclaration préalable de travaux: the planning declaration for visible exterior work: facade colours, windows, pools, small extensions, and AC, heat pump or solar units
- Devis: the written quote that is legally binding once you sign it
- Dommage-ouvrage insurance: the policy an owner must take out before a structural renovation or new build starts, so décennale-type (ten-year insurance) damage gets repaired without waiting for a liability ruling
- DPE: Diagnostic de Performance Énergétique; France's A to G energy rating, needed for every sale and rental
E
- Éco-PTZ: the zero-interest loan for energy renovation; no income conditions, up to 50,000 EUR, principal residence only
- EDF OA: the 20-year contract under which EDF buys the solar electricity you don't use; the rate for new contracts fell to 1.1 c EUR/kWh in June 2026
- Enedis: France's electricity distribution network operator; handles grid connections for solar installations, new meters, and EV charging activation
F
- Fluide frigorigène: the refrigerant in heat pumps and AC systems; the type (R32, R410A, R290) appears on every quote and matters for environmental impact and long-term repairability
- France Rénov': the free public renovation advice service, and the website where MaPrimeRénov' applications are now made
G
- Garantie décennale: the 10-year builders liability insurance every French contractor must hold; what it covers and how to check a quote
I
- IRVE: Infrastructure de Recharge pour Véhicules Électriques; the qualification an installer legally needs for a home charger over 3.7 kW, and the key to 5.5% TVA (French VAT)
M
- Maître d'oeuvre: the person or firm who designs, tenders and supervises a renovation on the owner's behalf; distinct from the maître d'ouvrage (the owner), and must be an architect above 150 m²
- MaPrimeRénov': the French government's main grant for energy-efficiency renovations, for principal residences only
- Mon Accompagnateur Rénov': the approved adviser you must use for a MaPrimeRénov' whole-house grant; the grant pays 20% to 100% of the fee
N
- NF C 15-100: the French standard governing residential electrical installations; referenced on all CONSUEL certificates and relevant to any new circuit for heat pumps, EV chargers, or solar
O
- Onduleur: the solar inverter that turns panel output into power the house can use; string, micro or hybrid; usually the first part of a solar system to need replacing
P
- PAC (pompe à chaleur, heat pump): the French term for heat pump; air-air vs air-eau, and what a PAC quote should show
- PAC hybride: a heat pump paired with a gas boiler under one controller; 20% TVA and no MaPrimeRénov'
- Permis de construire: the full building permit for larger extensions and new builds; above 150 m² an architect must sign the plans
- PLU: Plan Local d'Urbanisme, your commune's planning rulebook for colours, roofs, pools and outdoor units; how to read it
R
- Réception des travaux: the signed handover that starts the 1-year, 2-year and 10-year guarantees; what to list and test before you sign
- Rénovation d'ampleur: the whole-house MaPrimeRénov' route for E, F and G-rated homes that gain at least two energy classes; principal residence only
- RGE certification: the label a contractor needs for MaPrimeRénov' and most CEE grants; not needed for CEE on an air-air split
S
- SIRET: the 14-digit number every French business has, and the quickest way to check that a contractor exists and is still trading
