Whether you're aiming to enhance your home's insulation, upgrade to greener appliances, or cut down on energy expenses, this guide is crafted to assist you in making a well-informed choice.

In this guide, we will uncover the various improvements and installations covered by ECO4 grants in the UK, such as loft insulation, efficient boilers, and renewable energy systems. We’ll explore how these improvements function, the benefits they bring, and the essential considerations you should weigh up before applying.

From grasping the fundamentals of eligible improvements to evaluating cost-effectiveness and potential savings, our detailed overview will provide you with all the information you need. Let’s work together to discover how ECO4 grants can help transform your home into a more sustainable and cost-efficient space.

What are ECO4 grants?

ECO4 grants are a pivotal tool for enhancing home energy efficiency and reducing environmental impact. They support the installation of eco-friendly solutions like insulation and low-carbon heating systems, which help lower your energy consumption and utility bills.

Unlike traditional home improvements that often involve costly and disruptive renovations, ECO4 grants facilitate upgrades that are both cost-effective and sustainable. These grants cover a portion of the costs, making it easier for homeowners like you to implement changes that not only conserve energy but also reduce carbon emissions.

Types of improvements covered by ECO4 grants

Loft insulation: Improves heat retention and reduces energy loss through the roof.

Cavity wall insulation: Fills the gaps between exterior walls to enhance thermal efficiency.

Solid wall insulation: Adds a protective layer to solid walls, significantly reducing heat escape.

Boiler upgrades: Replaces old, inefficient boilers with modern, energy-efficient models.

Each type of improvement offers unique benefits and eligibility criteria, which we will explore in detail throughout this guide. 

ECO4 grant-supported improvements not only enhance heating efficiency in the winter but also contribute to maintaining cooler interiors in the summer, making them an excellent choice for year-round home comfort.

How do ECO4 grants work?

In the UK, choosing the right type of home improvement supported by ECO4 grants is essential for enhancing energy efficiency, lowering utility bills, and reducing environmental impact. 

But how does each type of supported improvement work in line with the ECO4 grant? 

Loft insulation

Loft insulation acts as a barrier to heat flow, keeping your home warmer in the winter and cooler in the summer. It's installed in the attic space, significantly reducing the amount of heat escaping through the roof.

Loft insulation is relatively straightforward and cost-effective, with the potential for significant energy savings. It’s particularly suitable for older homes that may have outdated or degraded insulation.

For more detailed information about loft insulation, visit our dedicated loft insulation page.

Cavity wall insulation

Cavity wall insulation fills the gap between the inner and outer layers of external walls with material that reduces heat transfer. 

This can be a very effective way to improve your home’s heat retention and energy consumption, especially if your home was built after the 1920s, as these homes typically feature a cavity wall design. The installation process involves injecting insulation material through small holes drilled in the wall, making it minimally invasive but highly beneficial.

Solid wall insulation

Solid wall insulation involves adding a thermal layer to the inside or outside of solid walls. It’s more invasive and expensive than cavity wall insulation but is essential for homes without a cavity in the walls. 

External solid wall insulation also improves the façade of the building, while internal insulation is less disruptive to the home's exterior appearance. Despite the higher upfront costs, the long-term energy savings are considerable.

Boiler upgrades

Upgrading to a high-efficiency boiler can significantly reduce energy consumption and carbon emissions. 

Modern boilers are more efficient at converting fuel into heat and can be a key component in reducing household energy costs. Installation typically involves replacing an older, less efficient boiler with a new model, which can be done relatively quickly by a qualified professional.

For additional information on boiler upgrades and how they're supported by ECO4 grants, visit our electric boiler page.

Each type of improvement has its unique benefits and installation requirements, which are important to consider when planning to enhance your home’s energy efficiency through ECO4 grants. These grants not only make these improvements more accessible but also contribute to a greener, more sustainable future.

ECO4 grant eligibility

Applying for ECO4 grants in the UK is a structured process, designed to help households make their homes more energy-efficient at a reduced cost.

Step 1: Apply for an ECO4 grant

Research: Begin by visiting the Energy Saving Trust and other government resources to understand the eligibility criteria for ECO4 grants. This typically includes your income level, property type, and specific energy efficiency needs.

Consult: You may also want to consult with a local energy advisor or a certified ECO4 installer to discuss your circumstances and potential eligibility. 

SpotDif offers a directory of local energy advisors or certified ECO4 installers, complete with user ratings and reviews, to help you choose a trusted consultant to discuss their eligibility and needs.

Step 2: Conduct an energy assessment

Arrange an assessment: Contact a certified ECO4 installer to perform an energy efficiency assessment of your home. This will identify potential improvements that the grant could cover.

Receive recommendations: The assessor will recommend the most effective improvements for reducing energy consumption and enhancing home comfort.

Step 3: Obtain quotes

Gather multiple quotes: Obtain quotes from several approved ECO4 installers for the recommended work. This ensures competitive pricing and helps you understand the scope of the potential work.

Select an installer: Choose an installer based on their quote, experience, and any reviews or recommendations. At SpotDif, we can provide you with a reliable database of expert installers to help you make the best choice for your ECO4 grant. 

Step 4: Apply for the grant

Complete application forms: Your chosen installer will typically help you complete the necessary application forms for the ECO4 grant. This includes detailing the proposed improvements and demonstrating how they meet the grant’s requirements.

Submit documentation: Along with your application, submit any required documentation, which may include proof of income, property ownership, or energy bills.

Step 5: Approval and installation

Wait for approval: Once submitted, your application will be reviewed by the grant provider. This process can take several weeks.

Schedule the work: Upon approval, arrange with your installer to schedule a convenient time for the work to be carried out. Grant approvals often come with a deadline by which the work must be completed.

Step 6: Post-installation review

Inspection: Some grant schemes require a post-installation inspection to ensure the work has been completed satisfactorily and under the grant agreement.

Release of funds: Following a satisfactory inspection, the grant funds are typically paid directly to the installer or reimbursed to you, depending on the grant’s terms.

Step 7: Enjoy the benefits

Energy savings: Once the improvements are in place, you should start to see reductions in your energy usage and savings on your bills.

Increased comfort and property value: Beyond the financial benefits, your home will likely be more comfortable, and you may also see an increase in your property’s value.

By following these steps, you can navigate the ECO4 grant process from start to finish, making your home more energy-efficient and environmentally friendly while managing costs effectively.

Eligibility criteria for ECO4 grants

Eligibility for ECO4 grants in the UK is determined by a combination of factors including the homeowner’s financial situation, the type of property, and the specific energy efficiency improvements needed.

Income and benefits

Low-income households

To qualify for ECO4 grants, households typically need to have a combined income that falls below a certain threshold, which can vary by region and specific grant requirements.

Receipt of government benefits

Households receiving benefits such as Universal Credit, Pension Guarantee Credit, Income-based Jobseekers Allowance (JSA), Income Support, and others are often eligible. Each grant may have specific qualifying benefits, so it's important to check the latest criteria.

Property type and condition

Property eligibility

The grants are usually available for both privately owned and rented homes. However, eligibility can depend on the type of property (e.g., detached, semi-detached, terraced, flat).

Energy performance

Homes with poor energy efficiency ratings, typically rated E, F, or G on their Energy Performance Certificate (EPC), are prioritised to receive improvements under the ECO4 scheme.

Type of improvements

Not all energy efficiency improvements are covered under ECO4. Eligible improvements are usually those that significantly reduce energy consumption and carbon emissions, such as insulation (loft, cavity wall, underfloor), heating system upgrades, and sometimes renewable energy installations like solar panels.


While ECO4 grants are available across the UK, specific regions may have additional local schemes or partnerships that enhance or extend the basic ECO4 offers, potentially affecting eligibility.

Landlord and tenant agreements

The ECO4 grant is only eligible for homeowners. If you are a tenant, you must obtain permission from your landlords to make the improvements, and landlords may need to contribute to the cost of the installations, depending on the terms of the grant.

Applying for ECO4 grants

Prospective applicants should start by verifying their eligibility through the official Energy Saving Trust website or by contacting a local energy advice centre. 

They can provide guidance, help interpret eligibility criteria, and even assist in the initial steps of the application process. It’s important for homeowners to gather and prepare necessary documentation such as proof of income, benefit entitlement, and current EPC ratings to streamline the application process.
