The Energy Company Obligation (ECO) Scheme was established by the government to help households reduce carbon emissions and achieve the goal of becoming 100% carbon neutral by 2050.  

The latest ECO4 scheme provides grants to fund energy efficiency upgrades to homes reducing emissions, electricity and energy bills and targets low-income or vulnerable households. These grants can contribute towards new heating systems, loft or cavity wall insulation and other measures designed primarily to increase energy efficiency and reduce fuel poverty and energy costs (source: Home: ECO4).

The next revision launched was The Great British Insulation Scheme (GBIS). Announced in late March 2023 and launched in April 2023, GBIS (previously known as ECO Plus) is a £1 Billion energy efficiency scheme aimed at households with an EE rating of D or below. The measures are more streamlined than ECO4, and there is a key focus towards delivering cavity and loft insulation, as well as at least 20% of the funding being allocated to support low-income and vulnerable households.


Main Features of ECO4
