Germany Cuts Heating Subsidies: What Homeowners Need to Know

Introduction

Germany's coalition government has announced significant changes to its heating support programme. Subsidies for climate-friendly heating systems — such as heat pumps — are being reduced, with higher-income households bearing the largest cuts. At the same time, the government is lifting a previous restriction and once again permitting the installation of new oil and gas heating systems in homes. For expats living in Germany, whether you own a property or rent one, these changes could affect your renovation plans, your heating costs, and the decisions your landlord makes about your building. Understanding what is changing — and when — is essential before you commit to any home upgrade.

What Is Being Cut and Why

The current coalition is under pressure to reduce public spending, and heating grants are one of the areas on the chopping block. The main programme affected is the federal subsidy scheme for replacing old heating systems with greener alternatives, known as the Bundesförderung für effiziente Gebäude (BEG). Under the new plans, households with higher incomes will receive noticeably lower subsidy rates than before.

Previously, the programme offered tiered bonuses: all applicants received a base grant, with additional top-ups for low-income households and those replacing an old oil or gas boiler on an urgent basis. The new approach tightens eligibility for the higher bonus tiers and reduces the overall funding envelope available. The government argues that wealthy households do not need public support to make the switch to greener heating and that savings must be found somewhere in the budget.

For expats who own their home and were planning to install a heat pump or pellet boiler in the coming months, this means the financial calculation has changed. If you have not yet applied for a grant, it is worth checking the current rates on the official KfW or BAFA websites before assuming the figures you saw six months ago still apply.

Oil and Gas Boilers: The Ban Is Lifted

One of the most debated parts of Germany's climate policy in recent years was the plan to phase out new oil and gas heating installations in residential buildings. Under the previous government's rules, the installation of new fossil-fuel boilers was heavily restricted and, in many scenarios, effectively banned for new installations from a certain date onward.

The new coalition is reversing course. Installing a brand-new oil or gas heating system is once again permitted. Proponents of the change argue that this gives homeowners more flexibility, especially in rural areas where heat pump installation is technically difficult or where district heating networks are not yet available. Critics warn that it locks households into fossil-fuel dependency for another 15 to 20 years and undermines Germany's climate targets.

For expats, the practical consequence is straightforward: if your landlord or your own property needs a new heating system, oil and gas are back on the table as legal options. This may keep upfront installation costs lower in the short term, but it also means potentially higher running costs if energy prices rise again, as they did sharply in 2022.

What This Means for Renters

Most expats in Germany rent rather than own their homes, which means the heating decisions are made by the landlord (Vermieter), not by the tenant. However, the consequences can still reach you:

• Modernisation costs passed on as rent increases: Under German tenancy law, landlords can pass on a portion of renovation costs to tenants through a rent increase (Modernisierungsumlage). If your landlord upgrades the heating system — whether to a heat pump or a new gas boiler — they may be entitled to raise your rent by up to 8% of the net renovation cost per year.
• Your heating bills (Nebenkosten): The type of heating system in your building directly affects your monthly utility bills. A heat pump running on electricity may be cheaper or more expensive than gas, depending on current energy prices and the efficiency of the system.
• No action required from most renters now: Unless your landlord formally notifies you of a planned renovation, there is nothing immediate you need to do. But it is worth being aware of your rights if a rent increase notice arrives.

Frequently Asked Questions

Can my landlord raise my rent because of a new heating system?

Yes, under certain conditions. German law allows landlords to pass on 8% of the net cost of a qualifying modernisation measure per year as a rent increase. However, the total rent increase from all modernisation measures combined cannot exceed €3 per square metre per month over a six-year period for tenants paying less than €7 per square metre. Your landlord must notify you in writing at least three months before work begins. If you receive such a notice, consider consulting a tenant advice centre (Mieterverein) for a free check of whether the increase is legally valid.

Should I still apply for a heating grant if I own my property?

The subsidy programme still exists and still offers meaningful financial support, but rates have changed. Before making any decision, visit the official BAFA website (bafa.de) or the KfW website (kfw.de) for the current figures. Do not rely on older calculations. If your annual household income is above a certain threshold, expect a lower grant percentage than what was available in 2023 or 2024. An energy consultant (Energieberater) accredited under the federal programme can help you calculate whether the investment still makes financial sense for your specific situation.

Is a heat pump still worth it without the full subsidy?

This depends on several factors: the size and insulation quality of your home, local electricity prices, and how long you plan to stay in the property. In a well-insulated home, a heat pump typically delivers three to four units of heat for every one unit of electricity consumed, making running costs competitive with gas even at current prices. However, installation costs remain high. Getting at least two quotes from certified installers and running the numbers with current subsidy levels is the right first step.

Conclusion and Next Steps

Germany's heating policy is shifting again, and the changes are real and practical. If you own property in Germany, review your renovation plans and check current subsidy rates on the BAFA or KfW websites before signing any contracts. If you rent, be aware that your landlord's heating decisions may eventually affect your Nebenkosten bill or trigger a rent increase notice. The lifting of the oil and gas boiler ban does not mean eco-friendly heating has become less relevant — energy prices remain unpredictable — but it does mean more options are now legally available. Stay informed and, if in doubt, seek advice from a certified energy consultant or a tenant rights association.
