Free Boiler Grant For Low Income Households In UK
Apply for free boiler grant under the ECO4 scheme perfect for low-income families needing affordable, energy-efficient heating without spending any cost.
With rising energy prices in UK and an increasing focus on sustainability, heating a home has become a growing challenge, especially for families on lower incomes. The government funded ECO4 Scheme (Energy Company Obligation) is designed to ease this burden by offering free boiler grants to qualifying low income households.
These home heating grants help to replace your old, inefficient boiler with new, energy-efficient model that not only lower your heating bills but also make your home more comfortable and environmentally friendly.
In this article, we’ll explain exactly what the Free Boiler Grant is, who qualifies for it, how to apply, and how it can benefit your home and family.
What Is the Free Boiler Grant?
The Free Boiler Grant is part of the UK Government’s ECO4 initiative which is a nationwide scheme that helps low-income households to upgrade their old and broken heating systems with newer model at no cost.
This scheme is funded by major energy suppliers such as Heatzen, Cozyfy and Heat1. They are required by law to help improve home energy efficiency under the Energy Company Obligation scheme.
Through this free home heating grant, eligible homeowners and tenants can replace their old or broken boilers at no cost, helping reduce carbon emissions and energy bills. It’s a win for low income households who are struggling with daily expenses.
How ECO4 Scheme Works?
The ECO4 scheme, which runs until March 2026, focuses on improving the energy performance of homes across the UK especially those with low income or low EPC ratings like D, E, F or G.
If you qualify under this scheme then you can get:
- Free boiler replacements,
- Full central heating installations,
- Cavity wall and loft insulation,
- Air source heat pumps, and
- Smart thermostats for better heating control.
Once your application is approved, your installation is scheduled by our Eco provider. You don’t need to pay any upfront cost because it’s fully funded by UK government.
Why the Government Offers Boiler Grants?
The UK government aims to achieve net-zero carbon emissions by 2050, and one of the largest contributors to household emissions is heating.
By replacing old, inefficient heating systems, the government helps:
- Cut energy waste,
- Support fuel-poor families,
- Lower national carbon output, and
- Promote renewable energy adoption.
For many low-income families, the ECO4 scheme provides not just financial relief but also health benefits through warmer, safer homes.
