ECO4 Grants & Funding
Unlock ECO4 Grant Funding for Energy Efficiency Upgrades Across the UK
The ECO4 Grants scheme is a UK Government initiative designed to assist homeowners and landlords in Wales, England and Scotland in enhancing home energy efficiency.
If you’re grappling with high energy bills or residing in a poorly insulated property, ECO4 funding could cover upgrades such as insulation, heating systems and renewable technologies. At Cyd Innovation, we streamline the process. From assessing ECO4 eligibility to securing funding and coordinating installations, we’re with you every step of the way.
ECO4 Scheme Eligibility
Grant eligibility depends on the qualifying benefits below:
A home with an EPC rating of D, E, F or G
Ownership of the property, or permission from your landlord
A household income below £31,000, or receipt of a qualifying benefit
Qualifying Benefits Include:
Universal Credit (UC)
Child Tax Credit (CTC)
Working Tax Credit (WTC)
Income-Based Jobseekers Allowance (JSA)
Income-Related Employment and Support Allowance (ESA)
Income Support (IS)
Housing Benefit
Pension Credit (Guarantee or Savings Credit)
Child Benefit (subject to income caps)
For residents in Wales, ECO4 eligibility may also be determined through local authority-led routes, such as ECO4 Flex.
ECO4 Flex Scheme
The ECO4 flex scheme is a referral scheme within the wider ECO4 programme which widens the eligibility criteria, encouraging the improvement of home energy efficiency measures. Authorities identify, and refer certain households to these home energy improvements, going beyond meeting the expected ECO4 eligibility criteria referred to above.
Eligibility
Although eligibility may be widened, households are still expected to meet minimum requirements such as a low income (31,000 or less) or qualifying health benefits. The ECO4 Flex Scheme allows local authorities to target struggling households, otherwise missed by the standard ECO4 scheme eligibility in an attempt to tackle the wider issue of fuel poverty.
Households may qualify for ECO4 Flex Grants if any of the following are met:
- Less than £31,000 a year
- Vulnerability class (debt, health conditions, aged 65+)
- Health grounds (cardiovascular disease, mobility issues and respiratory conditions)
