Home Battery and Energy Label: Does It Increase Your Property Value?

Energy labels and property value: a strong connection

A better energy label is good for your wallet, both through lower energy costs and a higher sale value of your property. Research by CBS and NVM shows that a property with energy label A is on average €14,000 – €23,000 more valuable than a comparable property with label C. Properties with label G can even fetch 10-15% less than the average.

But does a home battery contribute to a better label? And thereby to a higher property value? The answer is nuanced — but for those who understand the complete picture, a home battery in combination with the right measures certainly offers a financial advantage.

How is the energy label determined in the Netherlands?

The Dutch energy label is determined using the NTA 8800 calculation method, which calculates the energy performance of a building based on a series of fixed parameters:

Factors that determine the label

The NTA 8800 calculates the primary fossil energy consumption (in kWh/m² per year) based on: heat loss through the building envelope (insulation, windows, doors), the heating system (gas boiler vs. heat pump), hot water preparation, ventilation, cooling, and own generation by solar panels. These are the factors that literally determine the label.

What is NOT included in the calculation

A home battery alone has no direct influence on the NTA 8800-calculated energy label. The standard calculates the theoretical energy performance of a building, not the actual consumption behaviour or the self-consumption ratio. What the battery does — buffering solar power for evening use — is not relevant for the label calculation.

What DOES a home battery contribute to?

Although a home battery does not directly improve the label, it makes three indirect contributions to property value:

• Increased self-consumption makes solar panels more attractive: solar panels DO improve the label (NTA 8800 counts renewable generation). A battery makes your solar panel investment more visible and attractive to buyers
• Lower energy bill = more attractive to buyers: although the energy bill is not included in the label, buyers increasingly look at actual monthly costs. A demonstrable saving of €400/year is a concrete selling point
• Future-proofing: with the net metering scheme ending in 2027, a home battery is increasingly seen by buyers as a must-have, not a luxury
• Smart Readiness Indicator (SRI): the EPBD introduces an SRI score in which a home battery carries significant weight. This is expected to become a selling point comparable to the energy label
• Complete renovation concept: those who install a battery as part of a broader renovation (heat pump + additional insulation + solar panels) CAN achieve a substantial label improvement

What does the science say about property value and sustainability upgrades?

Multiple studies show that sustainability measures leading to demonstrably lower consumption are valued by buyers. A joint study by Rabobank and NVM (2024) concludes:

Properties with a combined package of solar panels + home battery + energy label A or B sell on average 8-12% faster than comparable properties without this combination. The added value of a home battery alone is estimated by valuers at €1,500 – €4,000, depending on the system and market conditions.

Strategy: how to maximise the impact on property value

Want to install a home battery with property value in mind? Here is the smartest approach:

Do not invest solely in a battery but in a comprehensive sustainability package: additional insulation (a label step from D to B delivers more than any technical installation), a heat pump in combination with the battery (heat pumps DO have label impact), and solar panels (counted in NTA 8800). The battery then becomes the keystone that makes the system work optimally — and for buyers, the visible proof that the property is ready for the energy future.

Conclusion: the battery strengthens the overall picture

A home battery does not directly improve your energy label, but it is a powerful component of a complete sustainability package that DOES have label impact. Moreover, market appreciation for home batteries is growing rapidly as the end of the net metering scheme approaches.
