Germany’s government has struck a deal on its controversial heating law—but for millions of households, the reality may feel all too familiar: higher costs and fewer real choices.
After months of wrangling, the CDU/CSU–SPD coalition on Wednesday unveiled what it presented as a reset of the policy first pushed through under former economy minister Robert Habeck. Voters were promised a rollback. Instead, the system remains largely intact—just with the bill now more widely shared.
Under the new rules, tenants and landlords will split the costs of CO₂ charges, network fees, and so-called green gas. SPD parliamentary leader Matthias Miersch insisted the aim is to keep “climate protection affordable.” But for many, that will mean paying more—just in a different way.
The headline concession is that homeowners can still install gas and oil heating systems. But that freedom comes with strings attached. From 2029, these systems must gradually incorporate alternative fuels under a staged plan running through to 2040. From 2028, even existing systems will be hit with a green gas quota.
In practice, that means sticking with traditional heating is set to become steadily more expensive. Critics say the message is clear: you can keep your gas boiler—for now—but you’ll pay for it.
The government’s answer is to spread the burden. When heating systems are replaced, tenants and landlords will split the added costs linked to biogenic fuels during the early phases of the transition. But that doesn’t remove the pressure—it simply shares it.
And for homeowners, the stakes can be far higher. Switching to low-emission systems often requires major upgrades: new insulation, new piping, sometimes entirely new heating infrastructure. The price tag can run into tens of thousands of euros—or more—depending on the property.
That leaves many families facing a difficult calculation: absorb rising running costs, or take on major upfront investment to comply with the new direction of travel.
Ministers have rebranded the policy as the “Building Modernization Act,” distancing it from Habeck’s deeply unpopular original law. But beyond the new name, the core approach remains the same: make fossil fuel heating progressively less viable, and steer households towards alternatives.
For a government that promised to scrap the law, the outcome looks more like a relaunch. And for ordinary Germans, the question is not what the policy is called—but how much it will cost to keep their homes warm in the years ahead.
