Germany faces an 82% increase in heating costs since 2021 due to the shift from Russian gas following the Ukraine invasion. Predictions indicate that by 2025, heating a 70 square metre flat will cost 1,180 euros annually, a 15% increase from the previous year. Many tenants are surprised by high adjustment bills, with 13% of households spending over 40% of their income on housing. The transition to Norwegian gas has increased costs, and experts do not foresee a decrease in heating prices soon.
