Overview
- A coalition agreement announced Monday between CDU/CSU and SPD introduces a cost brake that splits certain heating surcharges 50/50.
- The split covers the CO2 price, gas network charges and biogas markups, with tenants still paying the fuel itself and the change starting in 2028 and 2029.
- The reform drops the 65% renewables requirement for new heaters and allows new gas and oil boilers under a staged bio-step that raises green shares from 2029 to 2040.
- Ministers plan to bring the new Building Modernization Act to the cabinet in mid-May before debate in the Bundestag.
- Tenant and environmental groups warn the safeguard may be limited because rising carbon prices, network fees and scarce biogas could still push household heating costs higher.
