The federal grant for heating replacement has been exhausted since 10 July 2026, new applications are currently not possible. The public grants of the nine federal states continue, and 360 million euros in federal funds are budgeted for 2027. What this means for your planning in concrete terms.
Federal grant: currently no new applications possible
The federal budget of the Sanierungsoffensive (renovation initiative) for 2026 has been exhausted since 10 July 2026. New registrations and applications for boiler replacement („Sauber Heizen für Alle" - clean heating for everyone) are currently not possible. The Sanierungsbonus (renovation bonus) was already closed for new applications on 2 February 2026 to concentrate funds on heating replacement.
Applications already submitted remain valid and will continue to be processed. For 2027, the funding framework is budgeted again with 360 million euros, for the first time separated into thermal renovation and boiler replacement.
Which public grant will you get? The installers will calculate it into your quote.
Free and non-binding, at most 3 checked installers from your region. Takes about 1 minute.
We are deliberately writing this so clearly here because many portals continue to advertise with "up to 7.500 euros federal grant". That was correct until July 2026 — today it is misleading. If you are planning now, you should know the situation instead of relying on money that is currently not available.
Which programmes apply in your federal state, how much is available and when to submit the application is shown in the Förder-Check (grant check) — or directly on the page of your federal state in the table below.
What is still possible now
Federal state grants continue. All nine federal states have their own programmes with their own budgets. Depending on the state and project, four-figure amounts are possible here — in some states significantly more.
Municipality grants are added on top in many regions and are regularly overlooked because they are hard to find.
Tax deductibility via the Öko-Sonderausgabenpauschbetrag (eco special expenses lump sum) if a federal grant has been paid out.
Plan now, submit later. Quote, heating load calculation and proofs need lead time. Those who have the documents ready in the drawer can submit them on the first day of the next tranche — and that is exactly what matters when a pot is empty within a few months.
Federal state grants at a glance
The conditions change constantly and depend on the building type, old system and partly on income. That is why you will not find any amounts here that might be wrong next week, but only where you need to start:
"Last checked" means: On this day we read the guidelines of the respective funding authority and compared them with our information. It does not mean that nothing has changed since then — the funding authority itself is always legally binding.
The installers in our network know the programmes of their federal state and usually handle the applications for you. Ask about this explicitly during the quote discussion — the effort required from you differs significantly depending on the company.
Your public subsidy by place of residence
Some municipalities add their own grant to the federal state's public subsidy, usually a few hundred euros. Select your federal state and municipality, and you will see the federal state and municipality with all conditions in one overview.

Only then place the order and have it installed.
If you install first and then submit the application, you will miss out on most programmes. This is the most expensive avoidable mistake when replacing your heating system.
What has recently changed
Public subsidy programmes often change without notice — and you usually only notice when an application is rejected. That is why we keep track of what we have noticed:
Lower Austria — Sauber Heizen für Alle
With the federal freeze, new registrations for „Sauber Heizen für Alle" (Clean Heating for Everyone) with the Lower Austria top-up have also been suspended; existing registrations remain reserved.
Federal Government — Sanierungsoffensive (Refurbishment Offensive)
The 2026 federal budget for „Kesseltausch" (boiler replacement) and „Sauber Heizen für Alle" (Clean Heating for Everyone) has been exhausted; new registrations have not been possible since then.
