How it works

Three steps. No surprises in between.

You stay in control the whole way. We only send an engineer once you've said yes to a fixed quote.

  1. 01 — Roof scan

    We scan your roof

    Type your address and our software scans your roof, checked by a member of our team: panel count, sunshine hours and savings in seconds.

  2. 02 — Home check

    Five minutes with your phone

    A short mobile form with a few photos of your roof, fuse box and meter. No home visit. Usually enough to firm up the quote to the pound.

  3. 03 — Quote

    Engineer-confirmed quote

    A qualified engineer confirms the design, then you get a fixed price, dates, hardware spec, warranties and SEG registration.

No salesperson visit until you want one.

Sized to your roof, not to our order book.

We will size it to what your house actually uses.

Amber is what the panels made. Teal is what the battery kept for the evening. The gap is what you still bought from the grid.

What people say afterwards

“The desktop survey flagged that our chimney would shade half the array. They talked us out of the wrong install. We eventually went ahead with a smaller system and it's spot on.”

FAQ
