Warmer homes and lower energy bills with ECO4

The ECO4 scheme, also known as the Energy Company Obligation, was introduced by the government to assist low-income households in making their homes warmer and reducing energy costs. This initiative offers grants for various energy efficiency improvements to help tenants in privately rented properties achieve more comfortable and energy-efficient homes.

As a tenant in a privately rented property, there are two ways to become eligible for ECO funding:

  1. Help to Heat Group: If you receive government benefits, you may qualify for ECO funding. 
  2. Local Authorities Flex (LA Flex): Your local authority may deem you as living in fuel poverty or being vulnerable to cold conditions, making you eligible for ECO funding. Check your Local Authority’s website for their specific eligibility criteria.

The specific energy efficiency measures available under ECO4 depend on your property’s Energy Performance Certificate (EPC) rating. A Thermatic Homes-approved installer can assess your home and recommend suitable measures.

For properties with EPC ratings of E, F, or G, funding may be available for various types of measures. It’s important to note that you’ll need to obtain permission from your landlord before proceeding with any funded works.
