Energy renovation can be very expensive. Incentives and funding to renovate underperforming buildings are crucial for achieving a decarbonised building stock in all EU countries. 

These incentives can take the form of obligations, such as phasing out fossil-fueled boilers, or financial support in the form of funding programs, tax reductions, subsidies for individual renovation roadmaps, or mandatory and subsidised energy efficiency advice. These funding schemes can influence investment decisions and motivate people to invest in the energy efficiency of their buildings.

The revision of the Energy Performance of Buildings Directive emphasizes the importance of Energy Performance Certificates (EPCs) as tools not only to express the measured energy efficiency grade of a building but also as a marketing tool for citizens to demonstrate the value of their properties.
