Sales of home batteries have increased following a recent change allowing them to be factored into a home’s energy label rating. Sellers are promoting this as a way to increase property value, as higher energy labels are associated with greater home worth. However, energy advisors and Milieu Centraal (a Dutch environmental organization) caution that the impact of a home battery on the energy label is minimal, if it exists at all. The inclusion of batteries in the label calculation is relatively new, leading to potential misrepresentation in sales tactics. Experts suggest the effect on the overall energy performance of a home is often negligible. Consumers are advised to be cautious about claims linking battery purchases directly to significant improvements in energy label ratings and property value. The debate centers on the actual contribution of these batteries to a home’s overall energy efficiency.
