1. Introduction: A New Era for Solar Grants

Rising energy bills are a major burden on UK households, with average electricity prices climbing over 50% in recent years.Solar PV has long promised relief, but upfront costs of £5,000–£10,000 put it out of reach for many. The 2025 Warm Homes Plan changes the game by offering grants up to £30,000—making “zero‑cost” solar installation a reality for eligible homeowners.
