The funding landscape is constantly changing. We show you which programmes are truly relevant in 2026 and how not to leave a single cent on the table.

Anyone wanting to renovate their home often faces a mountain of abbreviations: BEG, KfW, BAFA, iSFP. We shed light on the matter.
For individual measures such as window replacement or insulation, BAFA offers grants. Funding levels vary depending on the measure. With the iSFP bonus, the grant increases.
Special rules apply here. Those switching to a heat pump can receive attractive funding rates when all bonuses (base funding, climate bonus, income bonus) are combined.
Those converting their home to an efficiency house are rewarded by KfW with low-interest loans and repayment grants.
