Free Insulation Grants for Low-Income Households
In the UK, millions of families face the challenge of high energy bills and chilly homes — especially during the winter months. If you’re part of a low-income household, keeping your home warm can feel like a constant battle. The good news? You could be eligible for FREE insulation grants through government-backed schemes designed to help you cut costs, boost warmth, and improve comfort all year round.
This easy-to-follow guide will walk you through everything you need to know about free insulation grants — how they work, who qualifies, and how you can apply and start saving.
Free insulation grants are part of UK government-backed schemes designed to improve the energy efficiency of homes, especially for people on low incomes. These grants cover the cost of installing insulation in your home, which helps keep the heat in and reduces your energy bills.
Insulation can be added to various parts of your home, including:
- Loft insulation
- Solid wall insulation
- Internal wall
These measures reduce the amount of heat that escapes from your home, meaning you need less energy to keep it warm.
Full Cost Coverage
All insulation expenses fully paid—no upfront fees or hidden charges for qualifying homes.
Lower Energy Bills
Cut yearly heating costs by 25% with expert-installed insulation upgrades.
Many homes in the UK are still under-insulated, especially in the loft. Installing free loft insulation can help you save up to £250–£300 per year, making it one of the most cost-effective energy efficiency upgrades available today. Using the best loft insulation materials like mineral wool or rigid foam boards, this solution forms a thermal blanket that keeps warmth inside during winter and prevents overheating in the summer.
Loft insulation is especially beneficial in older properties where roof space is often the main area of heat loss. Looking for “free loft insulation under ECO4 scheme”? You may qualify — especially if your EPC rating is E, F, or G.
Proper solid wall insulation acts as a thermal barrier, helping to keep your home warm in the winter and cool in the summer. They work by trapping heat inside your home, stopping it from escaping through the roof or walls. This brings a wide range of benefits:
For homes in city centres or conservation areas where external work isn’t allowed, internal wall insulation is the best solution. It’s perfect for terraced houses, flats, and listed buildings that cannot undergo external wall upgrades. This method uses insulated boards fitted to internal walls, significantly reducing heat transfer.
If you search terms like “free internal wall insulation grant” or “internal insulation for solid walls,” you’ll find increasing demand among UK homeowners. Best of all, internal wall insulation under ECO4 is covered 100% — no hidden costs, and minimal disruption during installation.
If your home was built before the 1930s, chances are it has solid brick or stone walls with no cavity. That means you’re likely losing around 45% of your home’s heat through the walls. Solid wall insulation, either internal or external, can fix this problem and slash your energy bills. While this type of insulation was once costly, the ECO4 free insulation scheme now makes it accessible for low-income and vulnerable households. By applying for a solid wall insulation grant, you can make your home warmer, quieter, and more energy-efficient — with no financial burden.
The ECO4 scheme is the government’s latest energy efficiency grant, running until 2026. Under ECO4, large energy suppliers are required to fund energy-saving improvements for low-income and vulnerable households. This includes:
- Loft insulation grants
- solid wall insulation
- Internal wall insulation
The scheme targets homes with poor energy efficiency ratings (E, F, or G) and supports those receiving certain benefits or with a low household income.
1. You or someone in your home must receive at least one of the following benefits:
2. Your home must have a low energy rating, usually an EPC rating of E, F, or G.
3. Only homeowners can apply for new loft insulation under the ECO4 scheme
There are types of insulation that may be covered, depending on your property:
1. Loft Insulation
Loft insulation grant prevents heat from escaping through the roof. It’s one of the most cost-effective energy-saving measures, saving households up to £250 annually.
2. Solid Wall Insulation
Older properties with solid walls can benefit greatly from wall insulation for solid walls, whether applied internally or externally. Although it may come with a higher upfront cost, this type of insulation can dramatically increase indoor warmth, reduce energy waste, and help lower your heating bills long term. It’s an essential upgrade for homes built without cavity walls, ensuring better comfort and energy efficiency year-round.
3. Internal Wall Insulation
Internal wall insulation is a smart solution for improving the energy efficiency of older homes with solid walls. This method involves adding insulated boards or stud walls to the inside of external walls, helping to reduce heat loss and improve indoor comfort.
It’s especially useful for properties where external wall insulation isn’t suitable — such as terraced homes, flats, or listed buildings. By keeping more heat inside, it can significantly lower your energy bills and carbon footprint.
Proper internal wall insulation also helps prevent condensation, reducing the risk of damp and mould, which can affect your health and your home’s structure. Thanks to government-backed schemes like ECO4, qualifying households can get internal wall insulation fully funded — with no cost to you.
If you’re a homeowner and receive means-tested benefits, tax credits, or your home has a low Energy Performance Certificate (EPC) rating, you could be eligible for life-changing, government-backed energy grants created to support low-income families across the UK.

Upgrading your home with free loft, internal wall, and solid wall insulation is a highly effective way to enhance comfort, reduce heat loss, and cut down on rising energy bills. These energy-saving improvements don’t just make your living space warmer — they also improve your home’s Energy Performance Certificate (EPC) rating, which can increase your property value and long-term savings.
Without proper insulation, homes can lose up to 35% of heat through the walls and 25% through the roof.
