What the scheme was

GBIS was a government scheme delivered by energy suppliers, focused primarily on a single insulation measure per home in lower Council Tax bands with EPC D-G.

How it differed from ECO4

ECO4 focuses on lower-income and vulnerable households and supports multiple measures including heating. GBIS was broader on income but typically funded only one main measure per home.
