Understanding ECO4

The Energy Company Obligation (ECO) is a government initiative designed to help households lower their energy bills and reduce carbon emissions. Under the scheme, larger energy companies are obligated to provide support for energy-saving measures in domestic properties, with a particular focus on low-income and vulnerable households.

Eligibility Criteria

Before diving into the documentation, it’s essential to understand the eligibility criteria for the ECO4 scheme. Eligibility is typically based on household income, benefits received, and the property’s energy efficiency. Make sure to check the latest criteria as they can change with each phase of the scheme.

Required Documentation

Gathering the right documentation is crucial for a smooth application process. Here’s a list of what you’ll likely need:

1. Proof of Ownership or Tenancy

  • Homeowners: A copy of your deed or mortgage statement.
  • Tenants: Your rental agreement or a letter from your landlord giving permission for the energy-saving improvements.

2. Proof of Income or Benefits

  • Recent bank statements showing income.
  • Award letters for any benefits you receive (e.g., Universal Credit, Pension Credit).

3. Energy Bills

  • Recent energy bills to establish your current energy usage and costs.

4. Identification Documents

  • Valid photo ID such as a passport or driver’s license.
  • Proof of address, like a recent utility bill or council tax statement.

5. Property Information

  • Details about your property, including its size, type, and current heating system.
  • Any existing Energy Performance Certificate (EPC) or details that could help assess your home’s energy efficiency.

6. Additional Documentation

  • Quotes from approved contractors for the work to be carried out (we can do this for you)
  • Any relevant planning permissions or building regulation approvals (we can also take care of this for you)
