- A Simple Upgrade with Big Savings for Modern Homes
FREE CAVITY WALL INSULATION
If your home was built after the 1920s and before the mid-1990s, chances are it has cavity walls, two layers of brick with a gap between them. While this design helps prevent moisture from passing through the walls, it also allows a significant amount of heat to escape if left uninsulated.
That heat loss leads to higher heating costs, colder rooms, and wasted energy. But with free cavity wall insulation available through the UK Government’s ECO4 scheme (link to ECO4 details), you can prevent heat from escaping, reduce your bills, and make your home more comfortable, at no cost to you.
Key Benefits of Cavity Wall Insulation
- Lower Energy Bills
- Warmer Homes in Winter
- Cooler in Summer
- Better EPC Rating
- Environmentally Friendly
- Quick and Clean Installation
What is Cavity Wall Insulation?
Cavity wall insulation involves filling the gap between the inner and outer brick layers of your home’s walls with an insulating material such as mineral wool, polystyrene beads, or foam. This process dramatically reduces heat loss, making your home warmer in the winter and cooler in the summer.
The insulation is installed by drilling small holes in the outer walls, injecting the material into the cavity, and then sealing the holes. It’s quick, non-intrusive, and usually completed within 1 to 3 days, depending on the size of the property.
How Does It work?
Many homes built after the 1920s have a gap, or cavity, between their inner and outer walls. Without insulation, this cavity allows heat to escape, making your home harder and more expensive to keep warm.
Cavity wall insulation works by filling this gap with a specially designed insulating material, such as mineral wool or polystyrene beads. The material is injected into the wall through small holes drilled in the mortar joints, which are then sealed once the job is complete.
This creates a thermal barrier that traps heat inside your home in winter and keeps it cooler in summer. The result? Lower energy bills, improved comfort, and a reduced carbon footprint, all without altering the appearance of your property.
Why Switch to Cavity Wall Insulation?
Cavity wall insulation is one of the most cost-effective energy efficiency upgrades you can make. It’s suitable for millions of UK homes and can reduce heating bills by hundreds of pounds each year.
If your home has uninsulated cavity walls, you’re likely losing up to 35% of your heat through the walls. With proper insulation in place, your home will retain more warmth, use less energy, and feel more comfortable throughout the year.
