German energy cost pressures and heating law reforms

Overview

Following a late-June heat wave that drove wholesale electricity prices to €566/MWh, Germany’s energy landscape is being reshaped by new heating and carbon pricing legislation.

Under the Schwarz-Rot coalition’s heating law and the accompanying Building Modernisation Act, the requirements for renewable energy in new heating systems have been eased, repealing the previous mandate for 65% renewable energy. However, new cost-sharing rules will take effect on 1 January 2028, requiring landlords and tenants to split CO₂ charges and gas-network fees 50/50 for newly installed fossil-fuel boilers. From 2029, landlords must also cover half of the extra costs for blending climate-friendly fuels. For a typical 80 m² apartment, the annual burden for landlords could rise from €330 in 2029 to between €761 and €1,194 by 2045.

An Institute of the German Economy (IW) study notes that operating a gas system in a typical 10,000 kWh-per-year Altbau apartment could cost up to €2,000 annually, rising to €2,366 by 2045. This is driven largely by the “Biotreppe” green-gas quota, which mandates renewable gas levels of at least 10% by 2029 and 60% by 2040.

To mitigate these costs, KfW launched a subsidy programme on 21 July 2026, offering up to €28,000 (covering up to 80% of eligible costs) for households replacing fossil-fuel boilers with renewable systems. Additionally, the government approved a CO₂ price reform for fuels, maintaining a price corridor of €55 to €65 per tonne of CO₂ for 2027 to stabilize costs for gasoline, diesel, heating oil, and natural gas ahead of the EU’s ETS 2 expansion in 2028.

Claims

What the coverage asserts, and how well corroborated each claim is across sources.

Coverage disagrees

Sources make claims that cannot both be true. CLSTR reports the disagreement; it does not decide who is right.

"The Institute of the German Economy (IW) calculates that operating costs of a gas heating system can reach up to €2,000 per year."

vs

"Annual gas heating costs for a typical Altbau apartment are projected to rise from €1,080 in 2026 to €1,952 in 2040 and €2,366 in 2045."

Claim 2 limits operating costs of a gas heating system to a maximum of €2,000 per year, while Claim 3 projects costs of €2,366 in 2045, exceeding that limit; both cannot be true simultaneously.

[DISPUTED] The Institute of the German Economy (IW) calculates that operating costs of a gas heating system can reach up to €2,000 per year.
[DISPUTED] Annual gas heating costs for a typical Altbau apartment are projected to rise from €1,080 in 2026 to €1,952 in 2040 and €2,366 in 2045.
[● 2 SOURCES] The green‑gas quota (Biotreppe) requiring 10 % renewable gases by 2029 and 60 % by 2040 adds about €643 per year in extra costs by 2040.
[○ 1 SOURCE] The Building Modernisation Act introduces a 50/50 cost split for CO₂ charges and gas‑network fees on newly installed gas, oil, or liquid‑gas heating systems, effective 1 January 2028.
[○ 1 SOURCE] The previous requirement that new heating systems must use at least 65 % renewable energy has been removed under the new law.
[○ 1 SOURCE] The 50/50 rule does not apply to existing fossil‑fuel heating systems that continue operating.
