New eligibility criteria for the Federal Scheme for Energy-Efficient Buildings (BEG)have been in force since 21 July 2026. The grant for the installation of a climate-friendly heating system remains, in principle, 30 per cent of the eligible costs. For owner-occupiers, additional grant contributions may apply depending on household income.
However, the funding amount will be gradually reduced in future: the maximum funding amount for the first residential unit is currently 28,000 euros. From 1 February 2027, this maximum amount will be reduced by 750 euros for the first time and will subsequently be further reduced every six months.
Further information is available in our grant check or directly from KfW.
