Introduction
Energy bills are a major concern for many families across Wales. With rising costs and older homes losing heat quickly, thousands of households are left paying more than they should for heating. To tackle this problem, the UK Government introduced the ECO4 Scheme, which is available throughout Wales.
The ECO4 Scheme Wales provides free energy-saving upgrades such as insulation, new heating systems, and renewable energy solutions for households that qualify. The scheme focuses on supporting low-income families, pensioners, and people living in cold or inefficient homes.
This guide explains everything you need to know about the ECO4 Scheme in Wales, including eligibility rules, the areas covered, what improvements are available, and how to apply.
What is the ECO4 Scheme?
The ECO4 Scheme is the fourth phase of the UK’s Energy Company Obligation, running from April 2022 to March 2026. Its purpose is to:
- Reduce fuel poverty.
- Improve energy efficiency of homes.
- Support the government’s net-zero carbon goals.
Energy suppliers and approved installers deliver the scheme by providing free or heavily subsidised energy improvements. For Welsh households, this means a chance to live in warmer, more energy-efficient homes without paying for costly upgrades.
