Linky smart meter reading or bill: this figure takes precedence, and the section-by-section estimate is calibrated to it.
Entering these readings lets us measure your heating share instead of estimating it from your DPE.
⚠️ Enter metered kWh, not euros, unless your bill is based on your actual consumption rather than a fixed monthly instalment for the year. Your actual kWh are shown in your customer account, under consumption monitoring. Two months are often enough to refine the simulation: one in winter, one in summer.
