What is the Eco4 Grant, and How Can One Apply for It?

The Boiler Replacement grant emerges as a beacon of hope and opportunity in a world increasingly conscious of environmental challenges. Understanding this government grant and learning how to apply for it is key to unlocking transformative projects that champion green innovation and drive positive change.

It is a government-funded scheme that provides financial assistance to homeowners and private tenants in England, Scotland, and Wales to make their homes more energy efficient. 

It is the fourth and final phase of the Energy Company Obligation (ECO) scheme, which was introduced in 2013. The scheme is designed to help low-income and fuel-poor households save money on energy bills and make their homes more comfortable and healthier. 

According to stats from the Government of UK, around 10% of ECO3 deliveries are carried in the ECO4 scheme. On the contrary to this scheme, there is also ECO4 Flex which is aimed at supporting low-income households that do not receive any benefits; in this way, the net eligible pool becomes around 3.5 million homes.

Understanding the Eco4 Grant

The term “ECO4” encapsulates its purpose – a conscious effort to drive environmental innovation for future generations. Eligible homes for ECO4 funding must be in bands D-G of the Energy Performance Certificate (EPC). This means that they are considered to be in need of energy efficiency improvements. Households that receive certain benefits are also eligible for ECO4 funding, regardless of their EPC rating.

The UK Government grant can be used to fund a range of energy efficiency measures, including:

  • Insulation (cavity wall, loft, and solid wall)
  • Heating controls
  • Boiler upgrades (boiler Replacement Grant)
  • Renewable energy (solar panels, heat pumps)
  • Air source heat pumps
  • Thermostatic radiator valves
  • Draught proofing
  • Warm air heating systems

The grant funding you can receive will depend on your chosen energy efficiency measures and household income. Generally, you will receive a higher grant if you are on a low income or live in a fuel-poor area.

What is covered in the ECO Scheme

This scheme covers many energy-saving measures that can be applied to UK households. These include:

  • Insulation

It is the most common benefit of this funding scheme, and it helps homeowners to save up to 1800 pounds a year.

  • Green Heating Systems

It includes installing green heating systems such as biomass boilers, air source heat pumps etc. It includes state–of–the–art heating systems that are used to replace outdated boilers.

  • Boiler Repairing & Upgrading

All boilers cannot be replaced with an air source heat pump and thus, this government scheme provides repairing and upgrading options to make these boilers more efficient.

Perks and Benefits of Receiving a Grant

There are many benefits to receiving an ECO4 grant, including:

  • Reduced energy bills: Energy efficiency improvements can help you save money on your monthly bills. 
  • Improved comfort: A more energy-efficient home will be warmer in the winter and cooler in the summer, making living more comfortable. 
  • Increased property value: Energy efficiency improvements can increase the value of your property. This is because buyers are increasingly looking for homes that are energy efficient and cost-effective to run.
  • Reduced carbon emissions: Making your home more energy efficient will help to reduce your carbon emissions and contribute to a cleaner environment. 
  • Peace of mind: Knowing that your home is more energy efficient can give you peace of mind. You can be confident that you are doing your part to reduce your energy bills and carbon emissions, and you can also be confident that your home will be more comfortable and easier to heat.
