Matthias Miersch, chairman of the SPD parliamentary group, has made tenant protection the central condition for the black‑red coalition’s reform of the heating law. “With him there will be no law that leaves tenants on the costs” he told the newspaper ”Stern”.
Tenant protection is, for him, an essential point. “We have presented the key points; now the detailed work begins” added the SPD politician.
Already in the current framework landlords must draw on subsidies if they want to roll over modernization costs. In addition, the CO₂ price contains a “clear social steering” so landlords cannot simply pass rising expenses on to tenants. “We will use that as a basis for parliamentary discussions on the new Building Modernisation Law” Miersch announced.
This approach specifically protects tenants while simultaneously encouraging investment in climate‑friendly technology. “The subsidy for climate‑friendly heating systems must remain reliable if we are to keep encouraging replacements” he said.
Miersch praised the agreement reached by the CDU, CSU and SPD on the cornerstones of the building‑modernisation law. “As a coalition, we have achieved something that was enormously important at this time: we have eliminated a societal split” he remarked. “The last heating fiasco cost a great deal of trust, and I am glad we now have something new, because that was exactly what was needed”.
He emphasized that climate protection works not through sensational headlines, but through reliability, subsidies and clear guidelines. “We combine ambitious goals with social security-this is exactly what creates acceptance” Miersch concluded.
