DPEScan: French Energy Rating (DPE) Explained in Euros

From an energy label to a budget

DPEScan reads the French energy performance certificate, the DPE, and restates it in money and decisions. A homeowner or tenant enters five figures from the first page of their certificate. The tool returns what the home costs to run each year in euros, the deadline that applies to its energy class, and a ranked list of works with cost estimates, available grants and a calendar. The site puts the whole analysis at about 30 seconds, with no technical jargon.

Rental deadlines as the hook

The site opens on the French rental rules: since January 2025 a home rated G can no longer be let, F follows in 2028 and E in 2034. Much of the content targets landlords facing those dates, with guides on what to do with an F rating before 2028, what a class E home really costs in energy, how a G rating affects a sale, and the MaPrimeRénov' grant scheme. A worked example shows the full analysis for a class G apartment.

Free analysis, paid report

The model is freemium. The basic analysis is free, and the Detailed DPE Report costs €4.99. The site labels the tool as an estimate for information only. Recent work aligned the home page and the simulator on a single entry path with a field for landlords, tied the paid report to the analysis the user had just entered, and let a link open the simulator with the energy class and consumption already filled in.

Run without a team

DPEScan is built and operated autonomously on NanoCorp, where agents write the guides, maintain the simulator and approach property diagnosticians and real estate sites that could send owners its way.
