Germany rethinks the gas boiler ban

For several years, the potential phase-out of gas boilers has been one of the most debated elements of Europe’s climate policy. Many expected Germany to become a pioneer in restricting fossil-fuel heating systems, potentially setting a precedent for the entire European Union. However, a recent political agreement in Berlin suggests a different direction. Instead of introducing strict bans on gas and oil boilers, the German government is moving toward a more flexible regulatory framework that preserves consumer choice while encouraging cleaner energy sources.

The shift follows an agreement between Germany’s governing parties to reform the country’s building energy legislation. The responsible ministries are expected to prepare the draft law by Easter, and the regulation could enter into force by mid-2026. The legislation will also receive a new name: rather than the previous “Heating Law,” it will likely be referred to as the Building Modernization Act, reflecting a broader focus on improving energy efficiency in buildings.

One of the most significant changes is the removal of a controversial requirement introduced under the previous government. According to that rule, newly installed heating systems had to rely on at least 65 percent renewable energy. Critics argued that the measure effectively favored electric heat pumps and limited technological neutrality. By abolishing the requirement, lawmakers aim to restore freedom of choice for homeowners.

Under the proposed framework, households will once again be able to choose from a wide range of heating solutions, including heat pumps, hybrid systems, biomass heating, as well as traditional gas or oil boilers. While fossil-fuel systems will remain available, policymakers emphasize that the long-term objective remains the decarbonization of the heating sector. Instead of restricting consumer decisions directly, the reform shifts responsibility for reducing emissions toward energy suppliers.

To support this approach, Germany plans to introduce a “green gas” and “green oil” quota system. Suppliers will have to gradually blend climate-friendly components into conventional fuels. For natural gas, this may include biomethane, while heating oil could incorporate synthetic fuels produced from green hydrogen. The quota is set to begin at 10 percent in 2029 and increase in stages until 2040.

At the same time, the reform relies strongly on financial incentives to accelerate the transition to low-carbon heating technologies. Germany’s multi-billion-euro subsidy scheme for climate-friendly heating systems will remain in place, with funding secured until at least 2029. Homeowners replacing their heating systems may receive support covering up to 70 percent of investment costs, with additional bonuses available for early adopters and lower-income households. Overall, subsidies for heating replacement can reach up to €21,000.

The reform also aims to simplify administrative requirements related to municipal heat planning, particularly for smaller municipalities. Another important change is that existing heating systems can continue operating without mandatory replacement, easing concerns about costly upgrades. The government plans to review the effects of the reform in 2030.

Beyond Germany, the reform has broader implications for European energy policy. Berlin had previously supported the idea of gradually phasing out fossil-fuel boilers, a concept that could have influenced EU-wide legislation. Germany’s revised approach now highlights the challenge of balancing climate ambitions with economic and social considerations as Europe continues its energy transition.
