The EU Green Homes Directive introduces phased minimum energy performance standards for existing buildings based on nationally defined benchmarks. Italy missed the 31 December 2025 deadline to submit its implementation plan to Brussels and has previously sought to water down the directive’s energy efficiency requirements to protect local firms. In our experience advising international buyers, the regulatory uncertainty creates complexity for property transactions, particularly in historic buildings where retrofitting is challenging. We work with advisors who can assess both current energy ratings and potential compliance costs before finalizing any purchase.
