Do you want to do energy renovation works in your home? You can get a loan without interest called eco-PTZ. We tell you the conditions and the approach to be followed in order to benefit from it.

It exists 3 main categories of works concerned by the eco-PTZ:

  • Renovation works global allowing your home to reach a minimum energy performance
  • The works of rehabilitation of your non-collective sanitation facility by a device that does not consume energy.

Please note

It is possible to combine eco-PTZ and MaPrimeRénov' for finance the remainder of your works having been granted the right to MaPrimeRénov'. In addition, there is also eco-PTZ Condominium to finance energy renovation works for common parts and equipment or for private parts in the case of works of collective interest.
