What is EC04?

ECO4 is a UK government-backed energy efficiency “grant” that covers 100% of the costs for eligible households. that runs from 2022 to December 31, 2026.

Unlike a standard grant, it is a legal obligation placed on medium and large energy suppliers (like British Gas, Octopus, and E.ON) to fund energy-saving measures for low-income and vulnerable households.
