Overview
- Germany’s coalition, which sealed the deal Thursday, set a 50/50 split on the carbon price on heating fuels and gas network fees for any new oil, gas or LPG boilers installed in existing rental buildings starting January 2028.
- From January 2029, a staged “Biotreppe” will require growing shares of biogenic or synthetic fuels in those boilers, and the bio-fuel price components will also be shared equally in the first three steps.
- Tenant groups praised the shift of running-cost risk to owners, while landlord associations warned of heavy burdens on small landlords and experts cautioned that some owners may try to raise rents or pass costs through by other means.
- A new NRW study by Öko‑Zentrum NRW and co2online found heat pumps already cheaper to run, with oil‑heated homes paying about €945 more and gas‑heated homes about €505 more in 2024 than comparable households with heat pumps.
- The Gebäudemodernisierungsgesetz heads to cabinet in mid‑May, with the exact bio‑quota design, supplier reporting rules, subsidy details and hardship exceptions still unsettled and an evaluation of distributional effects planned for 2036.
