Have you heard of the UK Energy Efficiency Scheme ECO4?

As a UK homeowner, you might have come across discussions about the Energy Company Obligation (ECO) scheme. More specifically, its latest iteration, ECO4 is presently active. This government-backed initiative helps improve energy efficiency in homes. The aim is to reduce both energy bills and greenhouse gas emission.

Only some homeowners or private tenants who get certain government benefits can apply to grants under the ECO4 scheme. If you are on benefits, just keep reading because we’ll explore the history, benefits, and various grants available under the scheme.

History of the ECO4 Scheme

The ECO scheme was launched in 2013 by the UK government to tackle fuel poverty and reduce carbon emissions by improving the energy efficiency of homes. Since its inception, the scheme has undergone several iterations, with ECO4 being the latest, running from April 2022 to March 2026. Each phase has expanded on the previous ones, broadening the scope and improving the support available to homeowners. ECO4 continues this trend by focusing more on whole-house retrofits, ensuring comprehensive energy efficiency improvements.

Benefits of the ECO4 Scheme

The ECO4 scheme offers numerous benefits, making it a valuable opportunity for UK homeowners:

  1. Reduced Energy Bills: By improving your home’s energy efficiency, you can significantly lower your energy bills.
  2. Enhanced Comfort: Energy efficiency upgrades such as better insulation and modern heating systems can make your home warmer and more comfortable.
  3. Environmental Impact: Reducing energy consumption helps lower carbon emissions, contributing to a greener environment.
  4. Increased Property Value: Energy-efficient homes often have a higher market value and can be more attractive to potential buyers.

Which Grants Does the ECO4 Scheme Cover?

The ECO4 scheme offers a range of grants aimed at different aspects of home energy efficiency. Here are the main types of grants available:

1. Boiler Replacement Grants 

Old and inefficient boilers can be replaced with new, energy-efficient models under the ECO4 scheme. This can significantly reduce your energy consumption and improve heating efficiency.

2. Insulation Grants 

Insulation is one of the most effective ways to improve energy efficiency. The ECO4 scheme provides grants for various types of insulation, including cavity wall, loft, and solid wall insulation. Proper insulation helps maintain a consistent indoor temperature, reducing the need for excessive heating.

3. Air-Source Heat Pump Grants 

Air-source heat pumps are an eco-friendly alternative to traditional heating systems. They extract heat from the air outside and use it to heat your home. The ECO4 scheme offers grants to help cover the installation costs of these efficient systems.

4. First-time Central Heating Grants 

For homes that have never had a central heating system, the ECO4 scheme provides grants to install one. This can be particularly beneficial for older properties that rely on less efficient heating methods.
