How efficient is YOUR home?


With the ECO4 energy-saving grants, we're taking a significant step towards making homes in Great Britain not just more energy-efficient, but also addressing the urgent issue of fuel poverty. This government-backed initiative, part of the broader effort to curtail carbon emissions and combat fuel poverty, has been in action since the 1st of April 2022 and will continue until the 31st of March 2026 1. It represents the fourth and final stage of the Energy Company Obligation (ECO) program, aimed at improving the energy performance of domestic buildings, thereby making electricity and heat more affordable for homeowners 2.

Our focus with the ECO4 scheme is on those who need it most. The UK government's commitment of £12 billion in Help to Heat schemes—including the ECO4 grants—illustrates our dedication to creating warmer, more cost-effective homes across the country. This investment, along with schemes like the Boiler Upgrade Scheme and the Home Upgrade Grant Phase 2, underscores our comprehensive approach to enhancing energy efficiency, reducing energy bills, and ensuring eligibility for those in the most need 3. By applying for these grants, homeowners can significantly improve their energy performance certificate ratings, contributing to a greener, more sustainable future.

Understanding the ECO4 Upgrade

Understanding the ECO4 Upgrade is pivotal in recognizing its potential to transform homes into energy-efficient sanctuaries. Here's a breakdown of the core components of the scheme:

Minimum Requirements for Energy Efficiency:

  • The scheme sets forth new benchmarks, mandating upgrades for homes rated in bands D and E to achieve at least a band C, and homes in bands F and G to reach at least a band D 1.

Energy-Efficient Measures and Installations:

  • A variety of measures are encouraged under ECO4, including:
    • Insulation (cavity wall, loft, solid wall, underfloor)
    • First-time central heating
    • Renewable heating solutions
    • District heating connections
  • These interventions are designed to address the needs of the least energy-efficient homes and those in fuel poverty, with a focus on private tenure homes in energy efficiency rating bands E, F, and G 1.

Funding and Eligibility:

  • ECO4 measures can be co-funded with other grants or schemes, although blending funds from different government schemes with ECO4 is not permitted 1.
  • The scheme is open to homeowners or private tenants with properties that have low EPC scores or inefficient heating systems, offering various measures like heating improvements and smart controls free of charge 2.

By embracing a whole-house retrofit approach, ECO4 aims for a comprehensive upgrade, significantly enhancing the living conditions and energy efficiency of homes across the UK 1.

Financial Benefits

The financial benefits of the ECO4 scheme are designed to alleviate the burden of energy costs for eligible households, making it a cornerstone in our mission towards energy efficiency and sustainability. Here's a breakdown of the financial advantages:

Up to £10,000 in Funding: Homeowners and tenants can access up to £10,000 for implementing eco-friendly measures through the ECO4 scheme, covering a wide range of energy-saving installations from insulation to solar PV 11.

100% Cost Coverage for Eligible Measures: For many, the ECO4 scheme can cover up to 100% of the costs associated with energy efficiency improvements. This includes a broad spectrum of measures such as boiler replacement, draught-proofing, and electric heating 10.

Significant Savings on Energy Bills: By taking advantage of the ECO4 scheme, households can see a substantial reduction in their energy bills, with savings amounting to hundreds of pounds annually. This not only aids in managing household budgets more effectively but also contributes to the broader goal of reducing carbon emissions and fuel poverty 5.

Eligibility for these benefits hinges on various factors, including income and existing benefits, with provisions for households not directly claiming benefits through council ECO4 Flex rules. This inclusive approach ensures that more households can benefit from the scheme, fostering a warmer, more sustainable living environment for all 12 5.

Eligibility Criteria for ECO4 Upgrade

Determining eligibility for the ECO4 energy-saving grants is straightforward, focusing on both the financial and residential status of applicants. Here's a closer look at the key eligibility criteria:

Household and Property Criteria:

  • Homeownership or rental with an EPC rating of D or below is essential 10.
  • Properties must have an EPC rating of D, E, F, or G, with priority given to those rated E, F, or G due to limited funding for Band D properties 5 12.

Financial and Benefit Criteria:

  • Receipt of specific benefits within 18 months of installation, including but not limited to Child Benefit, Universal Credit, and Pension Credit 10.
  • For those not on benefits, meeting the LA Flex criteria with a household income of less than £35,000 and vulnerability due to health conditions qualifies applicants 10.

Additional Pathways for Eligibility:

  • ECO4 Flex allows local authorities and governments to identify eligible households not covered under the standard criteria, ensuring a broader reach 1.
  • In-fill eligibility may apply to households in close proximity to qualifying properties, expanding the scheme's impact within communities 1.

This multi-pathway approach ensures that the ECO4 scheme is accessible to a wide range of households, focusing on those in greatest need of energy efficiency improvements.

How does the ECO4 grant function?

The ECO4 grant is designed to enhance energy efficiency in the least efficient homes, specifically targeting properties rated in energy bands D-G which are often occupied by households experiencing fuel poverty. The initiative emphasizes a comprehensive renovation through a whole-house retrofit approach, aiming to significantly improve the energy performance of these homes.

What is the ECO grant for improving energy efficiency?

The Energy Company Obligation (ECO) is a government-backed scheme aimed at improving energy efficiency in homes. Its two primary goals are to reduce carbon emissions and alleviate fuel poverty. Eligible recipients can receive grants to make their homes more energy-efficient, which in turn can lead to lower energy bills.

What amount can one receive from the ECO4 grant?

The value of the ECO4 grant varies depending on the type of improvements being made. For instance, grants for first-time central heating can reach up to £7,000, while those for external wall insulation can be as much as £14,000. If multiple energy-saving measures are installed simultaneously, the grant amount may increase, potentially covering thousands of pounds in home improvements.

What is the timeframe for obtaining the ECO4 grant?

After you reach out for the ECO4 grant, contact is usually made within 1-3 business days to determine your eligibility. On average, the ECO4 funding process is completed within 30 days. However, this timeframe can change based on the specific insulation and heating improvements you are eligible for.
