Planning an energy retrofit
Upgrade in the right order with a renovation roadmap and expert advice.
Key points
- Define the required outcome before approaching providers
- Verify qualifications and relevant experience
- Compare written scope, responsibilities and extra costs
- Keep decisions and key evidence documented
Advice first, then build
Energy advice shows which measures complement each other. Insulating before replacing the heating can reduce the required heating capacity.
The renovation roadmap
The individual renovation roadmap (iSFP) arranges measures in sensible steps and can improve subsidies for individual measures.
Check subsidies
Current programmes and rates are published by BAFA and KfW. Applications usually have to be made before work starts.

Frequently asked questions
How many proposals should I compare?
Two or three genuinely comparable proposals are often more useful than many offers with different assumptions.
Are references proof of quality?
They show experience but do not replace checks of qualifications, contract and suitability for your project.
