An installer's proposal is built to win the job. We don't sell or fit anything — we read your half-hourly demand data and show you exactly where the money is, and whether solar, a battery or a tariff change actually pays for your site.
Installers and EPCs earn when you buy their solution, so their "free feasibility" points one way. We earn a flat £300 whatever the answer — sometimes it's "yes, this array pays in four years", sometimes "fix your tariff and demand profile first". You get the honest, engineered version, in writing, that you can put in front of any supplier — or your board.
