The ECO4 grant scheme offers significant help to low-income and vulnerable households, aiming to make their homes more energy efficient, reducing heating costs and contributing to environmental sustainability.
So far:
Over 3.1 million energy-saving measures have been installed.
More than 2.3 million homes across the UK have benefited.
However, nearly 13% of English households still struggle with fuel poverty.
There’s more work to do. Read on to discover how ECO4 support can help get your household out of fuel poverty; here’s everything you need to know about the ECO4 scheme.
What is the ECO4 Scheme?
ECO4 is the fourth phase of the ECO scheme, designed to assist low-income and vulnerable households in enhancing their home’s energy efficiency. This initiative not only makes homes warmer and more comfortable but also supports eco-friendly practices like reducing carbon emissions and improving energy use.
Funded by energy providers, ECO4 provides a comprehensive retrofit to eligible homes, covering various energy-saving upgrades. In many cases, it comes without any cost to the householder or tenant.
What is Included in the Scheme?
The scheme embraces a “whole house retrofit” approach, aiming for a thorough enhancement of a home’s energy efficiency. This includes the installation of:
Loft and wall insulation
Heat pumps
Solar energy panels
Electric storage heaters
Double glazing
Boiler upgrades
By addressing these key areas of the building’s fabric and technologies, ECO4 ensures that the houses not only meet current energy efficiency standards but are also prepared for a sustainable future, improving living conditions and reducing the household’s carbon footprint.
