Gram Énergie Areas We Cover in France
Gram Énergie carries out energy renovation projects in 23 departments across Île-de-France, Hauts-de-France and Grand Est. From its head office at 95 rue de Paris in Charenton-le-Pont, the company supports homeowners and co-ownership properties in identifying work suited to the home, the building and the aims of the renovation project.
Work may include an energy audit, loft, wall or floor insulation, an air-to-water or air-to-air heat pump, a thermodynamic water heater or a whole-home renovation. Depending on your project, certain forms of support may be considered, including MaPrimeRénov’, CEE (energy saving certificates), TVA réduite (reduced VAT) and Éco-PTZ (zero-interest eco-loan). Select your region, then your department, to access local information.

Tip: have your energy performance certificate (DPE) and energy bills to hand for a more accurate estimate.
