Why this guide exists

Commercial solar is a significant capital decision. The financial case is strong — but only when the numbers are calculated for your specific building, consumption profile and tax position. Generic claims and optimistic projections do not help you make a confident decision.

This guide covers the facts: what a commercial solar installation costs, how the tax treatment works, what the generation data shows for the South East of England, and what the end-to-end process looks like. Each chapter ends with a link to the Wattfinder calculator, where you can generate a personalised savings estimate for your own postcode.

SolarLeads prepares independent savings estimates for commercial properties across the South East. Our installation partner is GreenBulb Energy — MCS Certified, NAPIT Approved, RECC Member and IWA Approved Installer, based at Discovery Park, Sandwich.
