Every installer's quote is a sales document. We don't sell or fit anything — for £100 we read your whole bill and show you what's actually worth it: solar, a battery, a heat pump, the £7,500 grant, and the smart tariff most people are missing.
Installers earn when you buy a system, so their "free survey" points one way. Even the comparison sites get paid by the installer they send you to. We don't — you pay us a flat £100, we take nothing from any installer, and we've no reason to point you anywhere. Sometimes the honest answer is "fix your tariff first and hold off." You get that version, in writing, to take to any installer.
