45 minutes on a video call. We look at where your business is now, where you want it to be, and whether we're the right fit. If we're not, I'll tell you straight.

  • Where your enquiries come from now, and where they go missing
  • How many appointments you'd need to put the next team on
  • What's still open in your area. We limit how many installers we work with in each area, and check yours before you sign.
