The ECO4 Scheme

Grants & Funding

Could you be eligible for government funding to improve the efficiency of your home?

Running until March 2026, the government-funded ECO4 scheme is the fourth phase of The Energy Company Obligation (ECO), which aims to help low-income households to cut down on their monthly bills by upgrading their homes and heating systems. And it’s not just about saving money – it’s about helping vulnerable people stay warm and safe in the cold winter months, whilst also helping the UK to reach its goal of reducing emissions to net zero by 2050.

Under the ECO4 scheme, qualifying homeowners can access a grant for a wide range of efficiency improvements for their home. From solid wall insulation (internal and external), cavity wall insulation, loft insulation, and pitched roof & roof room insulation, to solar PV panels, heating systems & controls, and more.

At NCS, our fully qualified and certified engineers have helped homeowners to save money and improve the efficiency of their homes through each phase of the ECO scheme, arranging everything from the initial survey to completing the work safely, efficiently and to an exceptional standard of workmanship.

Please complete the application form below if you believe you may be eligible for government funding through the ECO4 Scheme. In some circumstances, it can cover the entire cost of your home’s efficiency improvements. The amount of funding available is also subject to a site survey to be carried out at your convenience by NCS.

Who is eligible?

Although the scheme is primarily focused on owner-occupied homes, ECO4 is available for private tenants (with the landlord’s permission), those on income-related benefits, and for properties with low EPC ratings and/or inefficient heating systems.

You can qualify for ECO4 if you receive certain benefits, such as:

  • Income based Jobseekers Allowance (JSA),
  • Income related Employment and Support Allowance (ESA)
  • Income Support (IS)
  • Pension Credit Guarantee Credit (PCGC)
  • Working Tax Credit (WTC)
  • Child Tax Credit (CTC)
  • Universal Credit (UC)
  • Housing Benefit
  • Pension Credit Savings Credit (PCSC)
  • Child Benefit (with specific income requirements)
  • Recipients of funding through the Warm Home Discount scheme

In addition, you may be eligible for the ECO4 scheme through the Local Authority Flex initiative, where your local authority can nominate properties to receive assistance. This is typically allocated to households with a total income of less than £31,000, and an EPC rating of D, E, F or G, but can be different for each local authority.
