Thinking about how to save energy at home? Wall insulation is where you can begin. If your walls aren't insulated, you're losing significant amounts of heat every single day, as much as 35% sometimes. This is like throwing money down the drain.
The government in the UK provides cavity wall insulation grants to subsidize the cost. And in case you qualify, you won’t have to pay a penny. The grants fall under schemes such as ECO4, aimed at making homes warmer and less expensive to operate. And ECO Energy Services has helped thousands of homeowners and tenants receive free insulation using the program.
Let’s break it down and find out how wall insulation grants save you energy and reduce your bills.
Why Wall Insulation Matters
Heat always travels from warmer places to colder areas. So, when it's cold, heat from your house gets out to the cold outer air. Walls are among the worst offenders. Actually, about one-third of the total heat loss in an uninsulated house occurs through walls.
When your walls are well-insulated, they retain heat indoors longer. What this means is that your heating system or boiler does not need to operate as much to keep you cozy. That conserves energy—and you save money.
Wall insulation also works in reverse. During summer, it keeps cool air in and hot air out and keeps you at ease throughout the year.
What Types of Wall Insulation Are Covered?
Not every home is identical. Walls can be of any of two basic types, based on what kind of walls your house possesses:
Cavity Wall Insulation
The majority of homes constructed since the 1920s have cavity walls. Two walls with a narrow space (or cavity) between them constitute these walls. If you have these in your home, you can have insulating material inserted to prevent heat loss.
The process of installation is speedy. Small holes are drilled in the exterior walls, the blowing in of the insulation, and then the sealing of the holes. Typically, it takes only several hours.
Solid Wall Insulation
If your house was constructed prior to the 1920s, it likely has solid walls with no cavity. Such walls can’t be filled, but you can insulate them in two ways:
Internal wall insulation – This provides an additional layer of insulation within your house.
External wall insulation – This provides both additional insulation and an outer weatherproof finish.
It's more expensive, yes, but you save more energy as well. And there's the ECO4 scheme to cover the expense.
How Much Energy Can Wall Insulation Save?
One of the best energy-saving upgrades you can do is to insulate walls. Here's how much you could save annually in heating bills:
Cavity wall insulation: Could save you £300 annually
Insulate solid walls: Potential to save £540 annually
And that's just the cost. You'll also be cutting your carbon footprint, and that benefits the environment as well. The savings just accumulate over time.
Who Is Eligible for a Wall Insulation Grant?
The UK government's ECO4 initiative targets those households that need it the most. You can be eligible to receive a grant to insulate your walls if:
You own your house or rent it privately
Your house is inadequately insulated or has low energy efficiency
You or a member of your household gets certain benefits (such as Pension Credit, Universal Credit, Child Benefit, etc.).
Your family's earnings fall below a specific threshold (typically less than £31,000)
Even when you're unsure, it's best to check. Some properties can qualify under local authority rules, even with no benefits.
How the ECO4 Scheme Works
The ECO4 scheme is paid for by the large energy suppliers. It's an initiative of the UK to combat carbon emissions and tackle fuel poverty.
Through ECO4, energy firms are required to assist low-income homes in making them more energy-efficient. This ranges from providing free or subsidised wall insulation, boiler replacement, and heat pumps.
You do not apply to your government or energy supplier directly. Companies such as ECO Energy Services coordinate the complete process—from eligibility checks to installation of the insulation.
