ECO3 government grant

The ECO3 Scheme

What is the ECO3 Scheme?

The ECO3 scheme (the third phase of the Energy Company Obligationnow transitioned to the ECO 4 Scheme) was introduced by the UK government, so homeowners and private tenants (with the landlord’s permission) could apply for a government grant to have their old and uneconomical room heaters replaced with electric storage heaters 100% free of charge.

Is your heating system inefficient with low EPC ratings?

The 3rd iteration of the scheme was replaced by the ECO4 grant in April last year. Take a couple of minutes to find out if you qualify for ECO 4 funding by answering a few questions.

The Government ECO scheme grant system applications open for April 2024.

ECO3 explained

The ECO3 grant scheme stands for the Energy Company Obligation and it was the third phase of the project that finished in March 2022 and was replaced with ECO 4 scheme from April 2022.

The UK Government ECO Scheme also branches out and includes ECO Scotland and ECO Wales Schemes.

Please note, UK Energy Support currently does not cover the ECO Northern Ireland Scheme government grant due to additional conditions.

The Government ECO3 Scheme: What Do They Say?

In their ECO3 guidance document, the UK government described to ECO3 scheme 2021 as:

‘The Energy Company Obligation (ECO) requires obligated energy suppliers to deliver energy, efficiency and heating measures to homes in Great Britain. These measures help households to keep their homes warmer, reduce their energy bills and reduce carbon emissions.’

For more information, take a look at the government’s Energy Company Obligation ECO document.

  • AFIP – Armed Forces Independence Payment*
  • Attendance Allowance*
  • Carer’s Allowance*
  • Child Benefit (under specific conditions)
  • Constant Attendance Allowance*
  • DLA – Disability Living Allowance*
  • Income Support

The ECO 3 scheme was replaced with ECO 4 and some benefits no longer qualify you for the grant. We marked them with * above.

This is a government backed scheme

In the past, people living in the property with solid walls weren’t eligible for the ECO3 scheme, so they missed out of the energy saving and affordable warmth of a new electric heater due to the high initial costs. ECO 4 intends to continue allowing solid wall insulation funding.

ECO 3 Installers

The government ECO3 scheme covered a wide range of home improvements because the overall aim is to reduce the carbon emissions in our homes across the UK based on the Government’s Carbon Saving Obligation guidance.
