Batteria Domestica and Energy Label: Does It Increase Your Property Value?

Energy labels and property value: a strong connection

A better etichetta energetica is good for your wallet, both through lower costi energetici and a higher sale value of your property. Research by CBS and NVM shows that a property with etichetta energetica A is in media €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 batteria domestica 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 batteria domestica in combination with the right measures certainly offers a financial advantage.

How is the etichetta energetica determined nei Paesi Bassi?

The Dutch etichetta energetica 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 consumo energetico (in kWh/m² all'anno) based on: heat loss through the building envelope (insulation, windows, doors), the heating system (gas boiler vs. pompa di calore), hot water preparation, ventilation, cooling, and own generation by pannelli solari. These are the factors that literally determine the label.

What is NOT included in the calculation

A batteria domestica alone has no direct influence on the NTA 8800-calculated etichetta energetica. The standard calculates the theoretical energy performance of a building, not the actual consumption behaviour or the autoconsumo ratio. What the batteria does — buffering energia solare for evening use — is not relevant for the label calculation.

What DOES a batteria domestica contribute to?

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

• Increased autoconsumo makes pannelli solari more attractive: pannelli solari DO improve the label (NTA 8800 counts rinnovabile generation). A batteria makes your pannello solare investment more visible and attractive to buyers
• Lower bolletta energetica = more attractive to buyers: although the bolletta energetica 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 regime di scambio sul posto ending in 2027, a batteria domestica 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 batteria domestica carries significant weight. This is expected to become a selling point comparable to the etichetta energetica
• Complete renovation concept: those who install a batteria as part of a broader renovation (pompa di calore + additional insulation + pannelli solari) CAN achieve a substantial label improvement

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

Multiple studies show that sostenibilità 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 pannelli solari + batteria domestica + etichetta energetica A or B sell in media 8-12% faster than comparable properties without this combination. The added value of a batteria domestica 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 batteria domestica with property value in mind? Here is the smartest approach:

Do not invest solely in a batteria but in a comprehensive sostenibilità package: additional insulation (a label step from D to B delivers more than any technical installazione), a pompa di calore in combination with the batteria (pompa di calores DO have label impact), and pannelli solari (counted in NTA 8800). The batteria 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 batteria strengthens the overall picture

A batteria domestica does not directly improve your etichetta energetica, but it is a powerful component of a complete sostenibilità package that DOES have label impact. Inoltre, market appreciation for batterie domestiche is growing rapidly as the end of the regime di scambio sul posto approaches.
