Overview
- The non‑profit co2online published its Heizspiegel 2026 on Monday and warned that millions of German households can expect materially higher heating bills.
- For 2026 the report projects large near‑term increases for oil and wood pellets, with heating oil costs up about 24 percent to €1,275 and pellets up about 17 percent to €870 for a representative 70 m² apartment.
- co2online forecasts a small average relief for natural‑gas heating in 2026 because of low early‑year procurement costs and the removal of the gas storage levy, but it says wholesale price rises could reverse that easing late in 2026 or in 2027.
- The study links long‑term cost pressure to rising CO2 prices, higher gas network fees from shrinking customer numbers, and the GModG 'Biotreppe' requirement to blend pricier green gases into supplies.
- co2online notes the renovation rate fell to 0.67 percent in 2025 and urges targeted funding, serial renovation programs and stronger advisory services while saying heat pumps remain the lowest‑cost long‑term option.
