Important: NI Schemes Are Separate
Northern Ireland does not participate in ECO4, GBIS, or the Boiler Upgrade Scheme — these cover England, Scotland, and Wales only. NI has its own devolved energy efficiency programmes. This guide covers what's available specifically in Northern Ireland, sourced from NI Direct and the Department for Communities.
