Energy

What does a home's EPC or energy label tell me?

Short answer

The label estimates energy use per m² under standard use. In the Netherlands the scale runs from A++++ to G and a label is valid for 10 years; in Flanders it is called the EPC label (A+ to F).

Explanation

A label is a calculation model, not a measurement of your use. It makes homes comparable. In the Netherlands, since 2021 the NTA 8800 method is used, with primary fossil energy use in kWh/m² per year.

Rules of thumb

  • NL: A++++ (best) to G; valid for 10 years; mandatory on sale and rental. [SW-S51]
  • Flanders new builds: at most E30 and at least 25 kWh/m² renewable energy. [SW-S50]
  • Flanders existing homes: labels E and F trigger a renovation obligation on purchase. [SW-S77]

Pitfalls

  • Your actual bill depends on household size, behaviour and tariff; the label is a standard estimate. [SW-S51]
