In its regular package of infringement decisions, the European Commission pursues legal action against Member States for failing to comply with their obligations under EU law. These decisions, covering various sectors and EU policy areas, aim to ensure the proper application of EU law for the benefit of citizens and businesses.

The European Commission decided to open infringement procedures by sending letters of formal notice to Estonia (INFR(2025)2184), Italy (INFR(2025)2186) and Hungary (INFR(2025)2185) for failing to fully transpose into national law Article 17(15) of the recast Energy Performance of Buildings Directive (EPBD), Directive (EU) 2024/1275. The 2024 recast EPBD sets out how the EU can achieve a fully decarbonised building stock by 2050 via a range of measures and thereby reduce energy bills for European citizens by structurally boosting the energy performance of buildings. The Directive has two transposition deadlines. While the main deadline is 29 May 2026, provisions for the Member States to stop providing any financial incentives for the installation of stand-alone fossil fuel boilers, in accordance with Article 17(15) had to be transposed into national legislation by 1 January 2025.
