How your enquiry is handled
Your enquiry is passed to one suitable installer who can price the work — never sold to a panel of installers or a lead broker — and this site may receive an introduction fee for that. No marketing list, no cold calls. If your barn doesn't suit solar, the summary says so plainly and says why.
