Frequently asked questions
Is it really all free?
Yes. The score, the full report, the dashboard, the per-system plans, My Plan and the MOOC are free, with no card required.
What does full access include?
The works costed and ranked by priority for your home, grants estimated on the public scales, the EPC trajectory — plus the dashboard, per-system plans (energy, water, food, heating, garden), local risk exposure, My Plan and its 3D projection, and the MOOC.
Do I need an account?
The 2-minute diagnostic works without an account. A free account keeps your simulations, your plan and your MOOC progress.
Are the grant amounts guaranteed?
No, they are indicative estimates computed on the public scales in force. Only quotes from certified (RGE) companies and the funding bodies' decisions are binding.
