Upgrading to a new efficient boiler can save your heating bills and your carbon footprint. Replacing a boiler, nevertheless, is a costly exercise, and most homeowners can hardly manage it.
That’s where free boiler replacement grants become a godsend for them. Government-funded programs like the ECO4 scheme in 2025 go a long way in providing funding for low-income and disadvantaged sections of society for the free installation of a new boiler.
This guide explains who can claim a free boiler grant, a general summary of how the scheme works, and a simple, step-by-step application for one.
What Is the Free Boiler Replacement Grant?
The free boiler replacement grant forms part of a UK government drive towards enhancing domestic energy efficiency. Under ECO4, homeowners and tenants who qualify can have new, efficient, and modern boilers installed in place of inefficient, older ones at no expense to them.
These grants are backed by big energy providers, who have a compulsory part in financing poor and low-income communities in reducing loss of energy.
Having a new boiler installed can make your property less expensive, efficient, and environmentally friendly to maintain.
Who Is Eligible for a Boiler Grant in 2025?
The ECO4 scheme is designed with high qualification requirements in a view to channel funding towards beneficiaries in dire need. To obtain a grant for a new boiler, one must meet these requirements:
Your Current Boiler Needs To Be Ineffective
- Your boiler will have to be outdated, in disrepair, or incredibly inefficient.
- Or it should be 10-15 years old.
- You must not have an existing condensing boiler, as these are already energy-efficient.
You Must Own a Home or a Tenant in a Home
- Homeowners can apply but must have a minimum level of income.
- Private tenants can also become entitled but with the agreement of the landlord for a new boiler installation.
- Council and housing association housing is not eligible for ECO4 boiler grants.
Your Home Must Be Energy-Inefficient
- Your home will have a poor Energy Performance Certificate (EPC) rating of below D, E, F, or G.
- Homes with better insulation and newer heating systems may not qualify.
You Must Receive Certain Benefits
The ECO4 grant for a boiler is for low earners, and for that reason, you will have to receive at least one of the following:

How Much Can You Save with a Free Boiler Grant?
A new boiler will range in price between £2,500 and £4,500 when installation is included. Under an ECO4 scheme, a new, A-rated boiler can be installed for free, and a thousand pounds, at least, saved in initial expense.
Additionally, modern boilers use a lot less fuel to heat your property, and in consequence save a significant amount of money in terms of your utility bills, reducing them between £300 and £500 a year.
What Types of Boilers Are Available Under the Scheme?
Under the ECO4 scheme, homeowners with a qualification can gain access to A-rated condensing boilers. They use a new technology that can reuse wasted heat and, in consequence, become a lot cleaner and more efficient.
The scheme predominantly provides for gas boilers, but in a few instances, renewable options such as an air source heat pump can be advised in substitution. Installation of the most efficient system for your property, with overall reduced consumption, is a target of the scheme.
