Who Qualifies for a Boiler Grant, and Which Ones Are Available?
The upfront cost of replacing a boiler can be significant, but for many households in the UK, free boiler grants can provide much-needed support. These grants are part of the UK government's ECO scheme and other initiatives aimed at improving energy efficiency, reducing net zero carbon emissions, and helping low-income households save on energy bills. In this guide, Switched ON London breaks down who qualifies for a free boiler and the types of grants currently available.

Understanding Boiler Grants
Free boiler grants are part of government schemes designed to help eligible households upgrade to modern, energy-efficient boiler systems. These initiatives, including the Energy Company Obligation (ECO scheme) and the boiler upgrade scheme (BUS), not only aim to lower energy bills for households but also support the transition away from fossil fuel heating systems. Energy companies and local energy suppliers target support towards those most affected by fuel poverty and those needing energy-efficient home improvements.
Who Qualifies for a Boiler Grant?
Eligibility for a free boiler replacement depends on several factors, including qualifying benefits, existing boiler condition, and your energy performance certificate rating. You can check your eligibility criteria directly through an approved ECO installer or the UK government website. Those receiving income-related benefits often qualify for the government's ECO scheme. This includes income support, income-related employment and support allowance, working tax credits, pension credits, or child tax credits.
Even if you're not receiving benefits, you might still qualify for energy efficient home upgrades if your household meets certain criteria. Properties without gas mains supply or those relying on oil boilers may be eligible for additional support. Your current boiler's efficiency rating is also crucial - homes with an inefficient boiler are more likely to qualify for free boiler replacement schemes.
The age of your existing boiler and its energy efficiency rating plays a significant role. Most free boiler grant schemes target replacing older heating systems with A-rated boiler installations or renewable energy systems like an air source heat pump or ground source heat pump. Social housing tenants should check with their housing association, as different schemes may apply.
Types of Boiler Grants Available
The Energy Company Obligation (ECO scheme) is the primary boiler grant initiative. Through this scheme, energy companies provide funding for new boiler installation and other energy-saving improvements such as cavity wall insulation and heating controls. Qualifying households could receive a free boiler or significant support towards boiler replacement costs.
The Boiler Upgrade Scheme (BUS) focuses on renewable heating systems, offering substantial grants for heat pump or biomass boiler installations. This scheme helps property owners transition from fossil fuel heating to more sustainable options. For those in Northern Ireland, separate schemes may be available through local energy suppliers.
Local authorities often provide additional support through various energy-saving measures. These might include help with boiler repairs or funding towards a new boiler installation. Some schemes combine boiler upgrades with other energy-saving improvements to create a more energy-efficient home.
How to Apply for a Boiler Grant
The application process typically starts with checking your eligibility for a free boiler grant scheme. An approved ECO installer can assess your current boiler and confirm whether you qualify for the UK government's ECO scheme or other initiatives. They'll handle the application process and guide you through any required energy performance certificate assessments.
If you qualify for a boiler grant, the installer will explain the available options, whether that's an energy-efficient gas boiler or renewable heating systems like a heat pump. SwitchedON London provides professional boiler installation services and can help you understand the best choice for your property.
Why Upgrade to an Energy-Efficient Boiler?
Installing a new, energy efficient boiler offers multiple benefits. Modern heating systems, whether traditional gas boilers or renewable options like an air source heat pump, can significantly reduce your energy bills. They also help lower carbon emissions, supporting the UK's commitment to net zero carbon emissions.
Free boiler grants provide vital support for low income households needing to upgrade their heating systems. Whether through the government's ECO scheme or the boiler upgrade scheme (BUS), eligible applicants can access significant support towards energy efficient home improvements.
