Apply for an investment grant for the energy-efficient refurbishment of residential buildings

You can receive a grant of up to EUR 30,000 per housing unit for an energy-efficient renovation. A housing unit is an apartment or a house in which people live together.

You can receive a grant for the following measures:

• Complete refurbishment of a building into a so-called KfW Efficiency House.
• Thermal insulation of
  • walls,
  • roof surfaces and
  • storey ceilings,
• new windows and exterior doors,
• renewal and installation of a ventilation system,
• renewal and optimisation of heating systems older than two years.

The amount of the subsidy depends on the type and cost of the renovation. For example, 10 percent of the costs for individual measures will be subsidised, up to a maximum of EUR 5,000. If you renovate your entire residential unit in accordance with the so-called KfW Efficiency House 55 standard, you will receive 30 percent of the costs, up to a maximum of EUR 30,000. The KfW Efficiency House standard evaluates a renovation according to the energy savings that can be achieved through it.

If the subsidy amount is less than EUR 300.00, you will not receive any subsidy.

You can receive a subsidy for your housing unit if the building application or building notification for it was submitted before 1 February 2002. You cannot receive a subsidy for boarding houses as accommodation facilities with hotel-like services and for holiday houses and apartments as well as weekend houses.
The subsidy amount is based on the number of residential units after the renovation. Therefore, if you combine two dwellings into one in the course of the refurbishment, you will only receive the subsidy for one dwelling. If you split a large apartment, you can receive two grant amounts. You can also get a grant for converting space, for example, for converting an attic.

Before starting the measures, an energy efficiency expert must assess your planned measures. After completion of the refurbishment, he confirms the implementation.
Your refurbishment must meet minimum technical requirements in order for KfW to fund it. You must commission a specialist company to carry out the refurbishment.
