Overview of Heating Law Changes for 2026
Germany is introducing significant changes to its heating regulations starting mid-2026 under the new Gebäudemodernisierungsgesetz (GMG), which replaces the current Gebäudeenergiegesetz (GEG). One key change is the removal of the previous mandate that new heating systems must run on at least 65 percent renewable energy. Additionally, the installation of natural gas heating systems in new buildings will be allowed again, though experts warn of potentially high costs. Furthermore, government subsidies for switching to heat pumps (Wärmepumpe) will be reduced compared to current levels [Source 1][Source 4][Seed Article].
Details on Wärmepumpe and Gas Heating Regulations
The GMG seeks to advance Germany’s climate goals by encouraging renewable and energy-efficient heating technologies, but with increased flexibility. Unlike the GEG, which strictly required new heating systems to be 65% powered by renewable energy, this obligation will be lifted. Instead, funding schemes will continue to support low-carbon options until at least 2029, but with lower subsidies for heat pumps than expected earlier. Simultaneously, the previous ban on natural gas heating in new constructions will be lifted, permitting these systems again, though the economic viability is debated due to rising CO2 costs and potential long-term expenses [Source 2][Source 5][Seed Article].
Implications for Expats and Foreign Residents
For expats, international students, and foreign workers living in Germany, these heating law changes may impact housing costs and choices significantly. Rental properties with gas heating might become available again, but tenants could face higher heating bills as landlords may pass on increasing fossil fuel costs via utility surcharges. Those planning to buy or retrofit homes should anticipate stricter but more technology-neutral rules and must consider the reduced funding for heat pump installation when making energy-saving investments. It’s advisable for tenants and homeowners to stay informed about local municipal regulations, especially in cities with over 100,000 residents where heat planning and regulations may vary [Source 3][Source 4][Seed Article].
Practical steps include verifying heating types before signing rental contracts, factoring in potential higher energy costs due to fossil fuel use, and exploring eligibility for government incentives if considering installing renewable heating technologies. Awareness of deadline changes—such as the formal law enactment by May 2026 and the transitional periods for building renovations—will help residents comply with evolving regulations [Source 1][Source 4].
Conclusion
The new Gebäudemodernisierungsgesetz marks a shift towards technology openness in Germany’s heating sector, allowing a temporary easing in renewable energy mandates for heating systems while maintaining financial support for climate-friendly installations. Expats and foreigners in Germany should understand how these changes affect their housing options and potential costs, keeping in mind that natural gas heating will be re-permitted in new buildings, subsidies for heat pumps will decline, and the 65 percent renewable energy mandate will be suspended after 2026.
