If you live in a home that’s hard to heat, poorly insulated, or reliant on expensive electric heaters or solid fuel, you may qualify for the ECO4 grant in Wales, with many upgrades delivered at no cost to you.
The scheme is part of the broader UK Government Energy Company Obligation (ECO), but has unique local delivery routes in Wales. It’s specifically designed to help reduce fuel poverty, cut carbon emissions, and futureproof homes across all areas of Wales, urban and rural alike. Whether you’re a homeowner, tenant, or landlord, the Wales ECO4 scheme can provide the funding needed to install central heating for the first time, insulate your property, or switch to more efficient or renewable heating systems.
What Is the ECO4 Scheme Wales?
The ECO4 Wales programme runs from 2022 to 2026 and focuses on improving the least energy-efficient homes in the UK. In Wales, many homes still rely on old heating methods like storage heaters, bottled gas, coal, or wood. These systems are not only costly to run but also contribute significantly to carbon emissions and health issues.
The ECO4 grant for Wales aims to:
- Upgrade homes with insulation (loft, cavity, internal wall, underfloor, etc.)
- Replace or install energy-efficient heating systems (such as A-rated boilers, air source heat pumps, or first-time central heating)
- Improve indoor air quality and thermal comfort
- Increase the EPC rating of homes to C or above, where possible
- Reduce long-term energy costs for low-income or vulnerable households
In Wales, local authorities such as Ceredigion, Rhondda Cynon Taf, Gwynedd, and others have implemented ECO Flex pathways, an alternative eligibility route that widens access to households that don’t receive benefits but still struggle with high energy bills.

Why the ECO4 Scheme Is So Important for Wales
- Older housing stock – Many homes in rural Wales are poorly insulated and hard to heat.
- Fuel poverty – A higher-than-average percentage of Welsh households spend over 10% of their income on energy.
- Health benefits – Cold homes increase the risk of cardiovascular and respiratory illness, especially in older adults.
- Net Zero targets – Wales aims to become net zero by 2050, and improving homes is a key part of that journey.
The ECO4 scheme in Wales helps reduce pressure on the NHS, cut household emissions, and bring long-term energy security to communities across the nation.

The scheme operates across all Welsh local authorities, although each may have slightly different ECO Flex criteria.
As long as you have your landlord’s permission and the property qualifies, private tenants are eligible.
In most cases, the scheme covers 100% of the costs. If any minor top-ups are required, these are discussed upfront and only apply in exceptional circumstances.
This depends on the type of measures being installed. Insulation can take 1–2 days; heating systems may take longer.
We may still be able to help you access other support schemes. There are also options for private funding if needed.
