ImmoScout24 actively promotes sustainable living by ensuring transparency regarding energy efficiency and providing concrete solutions for climate-friendly properties. Since 2025, energy efficiency ratings have been displayed directly in the search results list for all properties with an existing energy performance certificate. This allows users to compare the energy performance of properties at a glance and make informed decisions.

A key feature is the modernisation calculator, which is fully integrated into the ImmoScout24 apps. It enables prospective buyers to realistically assess the scope and costs of energy-efficiency renovations. The high usage – with over 2.1 million enquiries in 2025 – demonstrates the great relevance of this service. In addition, ImmoScout24 connects users with suitable energy consultants and providers of solutions such as photovoltaic systems and heat pumps, thereby supporting the practical implementation of modernisation measures.

Furthermore, ImmoScout24 is continuously expanding its range of services relating to energy performance certificates. In addition to the sale of legally required energy performance certificates, new products have been developed that offer additional guidance – for example, by combining an energy performance certificate with a modernisation roadmap. This gives prospective buyers greater planning certainty and provides them with targeted support on their journey towards energy-efficient living.
