Oktave Single‑Property Owner Service

The Oktave Single‑Property Owner Service helps landlords secure and optimize the energy renovation of their rental properties.

We provide a complete preliminary project, including an energy audit, subsidy simulations, consultation with qualified contractors, and full administrative assistance for preparing grant applications.

Thanks to independent expertise, Oktave supports each property owner with:

• Technical analysis of the building and definition of a coherent long‑term asset strategy
• Technical and financial optimization of the renovation plan
• Selection of reliable and qualified contractors
• Preparation and administrative follow‑up of all aid applications
• Implementation of appropriate financing solutions when needed

With Oktave, landlords can improve energy performance, increase the value of their property portfolio, and ensure regulatory compliance — all while reducing project costs and complexity.
