A staggering 35% of a home’s heat escapes through its walls, surpassing any heat loss elsewhere, provided the loft is insulated. This astounding figure highlights the critical need to minimise heat loss via the walls, thereby increasing your heating bills. In pursuing a cosier, more energy-efficient home, UK homeowners are increasingly turning to a solution known as cavity wall insulation. This ingenious method has become a staple in British home improvement practices, directly addressing the unique challenges posed by the often unpredictable UK climate.

Cavity Wall Insulation
Traditional British homes typically feature walls with two layers, colloquially as ‘skins’, with a gap or ‘cavity’ between them. Cavity wall insulation involves filling this space with insulating material, preventing heat loss from inside your home and cold air from outside. Efficient insulation is crucial for any domicile, as it maintains warmth during the biting winter months and keeps interiors comfortable when summer’s mild warmth bathes the British Isles.
The Insulation Process
Insulating your walls begins with a survey by certified professionals to determine if your home is suitable. Only some properties, particularly older homes, may need more cavities. For those that are, the process is relatively simple and unobtrusive:
- Inspection: A specialist conducts a thorough inspection to ensure that your cavity walls are fit for insulation.
- Drilling: Small holes are carefully drilled into the outside walls, usually about the size of a coin.
- Filling: Using specialised equipment, insulating material, such as Thermo Bead, is blown into the cavity through the holes.
- Sealing: Finally, the holes are expertly sealed, matching your existing wall finish, so the work is barely noticeable.
This type of insulation is not merely energy-efficient but also environmentally friendly. The installation process ensures minimal disturbance to the household, a bonus for the ever-busy homeowner.
The Benefits for British Homeowners
The advantages of cavity wall insulation are manifold:
- Reduced Energy Bills: Keeping your home naturally warmer in winter and cooler in summer means relying less on heating and air conditioning.
- Enhanced Comfort: Eliminate cold drafts and hotspots throughout your home, fostering a more consistent and comfortable indoor temperature.
- Environmental Impact: By reducing energy consumption, insulation also decreases one’s carbon footprint—a direct benefit to the environment.
- Property Value: Investing in cavity wall insulation may enhance your property’s value by improving its energy efficiency rating.

Frequently Asked Questions
What is cavity wall insulation?
Cavity wall insulation fills the gaps between external walls. Every part of the wall must be filled with insulation correctly, so its important the right installer does it for you.
How is the insulation installed?
To insulate your cavity walls, the installer drills small holes at intervals in the outside wall of your home. The installer then blows insulation into the cavity using special equipment. Once all the insulation is installed, the installers fill all the holes in the brickwork.
Can I do the insulation myself?
Filling cavity walls is not a job you can do by yourself, you will need to hire a professional contractor.
What wall type do I have?
Houses in the UK mostly have either solid walls or cavity walls: A cavity wall is made up of two walls with a gap in between, known as the cavity; the outer wall is usually made of brick and the inner layer of brick or concrete block. Whereas a solid wall has no cavity, each wall is a single solid wall, usually made of brick or stone.
