Europe's buildings directive leaves investors waiting for the rules

The European Union's Energy Performance of Buildings Directive (EPBD) gave member states until 29 May 2026 to transpose its provisions into national law. That deadline has now passed. Not a single member state has met it.

The consequences reach far beyond a missed deadline. It has left property owners and investors across Europe in an increasingly uncomfortable position. Where things are headed is clear: Europe's building stock must be progressively decarbonised over the coming decades. Yet many of the national rules needed to translate that ambition into practical investment decisions remain unwritten, and for the property industry, uncertainty can be almost as damaging as regulation itself.

According to EY-Parthenon's latest EPBD Transposition Tracker, property companies are already postponing investments, refurbishment programmes and even new developments because they cannot reliably assess future obligations. Without national legislation defining specific thresholds, implementation timetables and potential penalties, investors are struggling to quantify capital expenditure requirements, assess stranded asset risk or compare regulatory exposure across cross-border portfolios. Dirk Rathlev, partner at EY-Parthenon and one of the report's authors, argues that binding national legislation has become a priority precisely because the current uncertainty is preventing the investment decisions that the Directive is intended to encourage.
