What the program was and which problem it solved
The Sanierungsoffensive des Bundes was Austria's federal funding push for climate-friendly homes, combining two tracks: the Sanierungsbonus for thermal-energetic renovation (insulation, windows, comprehensive refurbishment) and the Kesseltausch for swapping fossil-fuel boilers for heat pumps, biomass or district-heating connections. With €360 million earmarked for 2026, it was one of Europe's most generous per-project renovation programs, aimed at cutting heating emissions from Austria's older building stock.
Eligibility and geographic coverage
The program was federal, covering all of Austria. Private individuals could apply for single- and two-family homes, terraced houses and apartments in multi-storey residential buildings. The renovation bonus generally required buildings at least 15 years old. Applications worked through an online registration while budget lasted, followed by a formal application — a structure that made the program's remaining budget the real eligibility criterion in its final months.
Amount and funding structure
The 2026 round disposed of a maximum €360 million in federal funding. UNVERIFIED: the exact 2026 lump sums per renovation depth and heating type were published in the program's official onepagers (January 2026) but were not rendered in text form on the portal's current page — and with the round closed, they matter only to existing applicants checking their approved amounts in KPC-Online. Earlier program documentation described lump sums scaled to renovation depth (partial vs. comprehensive renovation) and capped as a percentage of eligible costs, plus dedicated boiler-replacement amounts.
How to apply and timelines
Projects under the 2026 round were funded from 24 November 2025. On 2 February 2026 the Sanierungsbonus track was stopped to keep the Kesseltausch running; then, on 10 July 2026, the ministry announced the entire 2026 round closed because the budget was exhausted. New registrations are no longer possible. Existing registrations and applications are unaffected and continue to be processed — applicants can track their status at any time through KPC-Online, the KPC's information portal.
Cautions and program gotchas
The program's first-come, first-served budget model meant late registrants got nothing — a structural risk in any capped Austrian federal program. Anyone encountering websites or consultants still "accepting applications" for the 2026 Sanierungsoffensive is dealing with outdated or misleading offers; the official portal confirms closure. Existing applicants should keep their registration documents and respond promptly to KPC requests, as incomplete files can stall payment. Whether a 2027 round follows has not been announced on the official portal.
