Home batteries now count toward your energy label
By Stefan Douw · Maker of Stekkerkompas
Since 29 May 2026 a home battery counts in the official energy-label calculation method for homes, the NTA 8800. The change follows from the European EPBD IV directive.
The conditions
A battery only counts if it meets three requirements: at least 5 kWh of storage, permanently connected in the meter cabinet per NEN 1010, and combined with solar panels. A loose plug-in battery does not count.
What it gains you
In the calculation a correction factor lowers the so-called EP2 value when there is demonstrably enough storage, and a lower EP2 value means a better label. The effect is limited: solar panels already weigh heavily, and a battery only stores, it generates nothing itself. For a home that already performs well, a battery can be the nudge into a higher label class.
What this means for you
The return on a home battery still sits mainly in more self-consumption and trading, not in the label. But if you are considering a battery anyway and sit close to a higher label class, this can weigh in, for example when selling or renting out.
Run the return on a battery for your situation in the calculator.
