Customer reviews
What our homeowners remember
Feedback focused on clear guidance and transparent studies, before talking about figures.
We wanted to understand before committing. The simulation gave us a clear first idea, then the on-site survey confirmed what was possible on our roof.

The explanations stayed simple from start to finish, with no jargon and no exaggerated promises. We understood what we were buying and why.

How it works
Four steps, no account needed
I describe my home
Postcode, property type, roof area and consumption: a few simple questions.
I see an estimate
Recommended system size, yearly production and estimated savings, computed with a deterministic engine.
I request a study
You choose whether to be called back so an advisor can check your estimate.
An advisor gets in touch
Only with your explicit agreement, at the time slot you picked.
Estimate your solar potential, then decide with a verified study.
You get a useful first estimate before leaving any contact details. Asking for a call back is always a choice, never a required step.
