Heating cost statistics 2025: Costs continue to rise – heat pump by far the cheapest heat generator

German households continue to use heating energy sparingly overall, while costs are rising at varying rates depending on the energy source. This is shown in the current 2025 heating cost statistics from the real estate service provider Minol, which analyzes consumption and expenditure for heating and hot water in 2025 based on heating bills from hundreds of thousands of households.

Leinfelden-Echterdingen, April 2026The trend of recent years continues. Overall energy consumption remains at a moderate level, but shows a slight increase for several energy sources in the current billing year. For natural gas, average consumption for heating and hot water rose from 119 kWh to 123 kWh per square meter of living space in the current billing period. At the same time, costs increased from €16,03 to €18,08 per square meter, representing a rise of 12,8 percent. For heating oil, consumption for heating and hot water increased from 119 kWh (11,9 liters) in 2024 to 124 kWh (12,4 liters) in 2025 per square meter. Costs decreased slightly from €15,87 to €15,43 per square meter.

District heating costs are rising significantly

District heating consumption remained almost identical at 106 kWh per square meter in 2024 and 107 kWh per square meter in 2025. However, costs increased significantly by 27,2 percent to €17,94 per square meter. This is due to the way the district heating market operates: price adjustments follow contractually agreed formulas that reflect energy price indices with a time lag of up to 15 months. As a result, the price spikes of the energy crisis are only now partially impacting end-customer prices.

Heat pump performs best

With an average consumption of 86 kWh and costs of €9,33 per square meter for heating and hot water, it is significantly cheaper than all fossil fuel alternatives. Since heat pumps are not subject to CO₂ pricing for fossil fuels and the increasing share of renewable energies will have a dampening effect on electricity prices in the long term, this cost advantage could increase further in the coming years.

Residents of large buildings have an advantage.

A consistent trend continues to emerge regarding building size: the larger a building, the lower the consumption and costs per square meter. Larger apartment buildings benefit from more efficient heating systems, more even heat distribution, and lower heat losses per unit. Heating-related ancillary costs such as maintenance, operating electricity, and meter reading are also significantly lower in these buildings.

Moderate consumption, rising costs

“The figures confirm what we have been observing for years: Consumption remains moderate, partly due to greater transparency in consumption recording and the requirements of the current Heating Costs Ordinance. Nevertheless, costs are rising because energy prices, infrastructure costs, and network charges are increasing. The district heating increase of over 27 percent is a particular warning sign,” explains Oliver Bartsch, Head of Billing at Minol Messtechnik W. Lehmann GmbH & Co. KG. According to the Heating Costs Ordinance, landlords must convert their buildings to remotely readable metering technology by the end of 2026 at the latest and provide their tenants with monthly consumption information. This allows residents to better understand and manage their energy consumption, which is all the more important given the high energy prices.

Improving the energy efficiency of buildings

In addition to digital measurement technology, holistic energy solutions for existing buildings are gaining in importance. With the B.One Guide Minol supports owners and property managers in planning renovation measures in a structured manner and implementing them economically. The goal is to improve the energy efficiency of buildings in the long term. B.One tenant electricity It also enables the direct use of locally generated solar power in the building. "The energy transition in the building sector is not a question of if, but when. Those who invest in efficient heating technology and renovations today protect themselves against the foreseeable further increases in the costs of fossil fuels. Minol supports owners and landlords with intelligent solutions for metering technology, billing, and digital consumption control," adds [name/title of person].
