The ECO4 Scheme: A Comprehensive Guide

Check Your Eligibility Here.

The Energy Company Obligation (ECO) scheme, now in its fourth iteration as ECO4, represents the UK Government’s ambitious plan to tackle fuel poverty and reduce carbon emissions across the country. This latest phase, which began in April 2022, aims to provide significant improvements in the energy efficiency of low-income and vulnerable households. This article delves into the nuances of the ECO4 scheme, outlining its objectives, eligibility criteria, and the types of improvements it encompasses.

Objectives of ECO4

The ECO4 scheme is designed with dual goals: to reduce the UK’s carbon footprint by improving the energy efficiency of homes and to assist those in fuel poverty in heating their homes more affordably. By focusing on low-income and vulnerable households, ECO4 not only seeks to bring about a reduction in energy bills but also aims to contribute to the broader national targets for carbon reduction. This initiative is part of the UK’s commitment to achieving net-zero carbon emissions by 2050.

Eligibility Criteria

The eligibility criteria for the ECO4 scheme have been refined from previous iterations to ensure that support is directed towards those who need it most. Households can qualify for the scheme based on income, receipt of certain benefits, or the presence of vulnerabilities to cold-related illnesses. Importantly, the scheme is accessible to both homeowners and those renting privately, provided they have the consent of their landlord. This broad eligibility is crucial for reaching a wide range of individuals and families who can benefit from improved energy efficiency.

Types of Improvements

ECO4 brings a variety of improvements aimed at increasing the energy efficiency of eligible homes. These improvements are carefully chosen to have a significant impact on reducing energy consumption and improving living conditions. They include, but are not limited to, the installation of loft and wall insulation, the upgrading of inefficient heating systems, and in certain cases, the replacement of single-glazed windows with more energy-efficient alternatives.

One of the most significant changes in ECO4 is the increased emphasis on “deeper” retrofits, which may include more comprehensive measures such as solid wall insulation and renewable energy technologies like solar panels. This shift acknowledges the need for more substantial upgrades to achieve long-term energy savings and carbon reductions.

The Application Process

Applying for assistance under the ECO4 scheme is designed to be straightforward, allowing eligible households to access the necessary improvements with minimal hassle. Interested individuals should contact energy suppliers participating in the scheme to express their interest and determine their eligibility. The supplier will then guide applicants through the process, which typically involves an assessment of the property to identify the most effective energy-saving measures.


The ECO4 scheme represents a critical step forward in the UK’s efforts to combat fuel poverty and reduce carbon emissions. By focusing on improving the energy efficiency of homes belonging to low-income and vulnerable households, the scheme not only aims to reduce energy bills but also to contribute to the broader environmental goals of the nation. As the scheme unfolds, it holds the promise of warmer, more sustainable homes for thousands across the UK, marking a positive stride towards a greener future.
