External Wall Insulation
For sustainable, cosy homes
Do you live in an older home with solid walls that are letting heat escape, making it feel cold and costing you money? External wall insulation is a highly effective solution for properties that cannot have cavity wall insulation.
It involves adding an insulating layer to the outside of your external walls, effectively creating a thermal barrier that keeps the heat inside your home, making it more comfortable and energy-efficient.
Benefits
Part of the heat pump will live outside of your house. This part often looks like a slightly larger air conditioning unit that you might see on buildings when you go abroad. They typically sit on the ground and will often be attached to one of your exterior walls.
External wall insulation is a significant investment, but it provides a comprehensive range of benefits for your home:
Improved Thermal Efficiency: It can reduce heat loss through your walls by as much as 45%, making your home feel warmer and more comfortable.
Lower Energy Bills: By dramatically improving your home's heat retention, you can save anywhere between £140 to £700 a year.
Minimal Disruption: Since the installation goes on the outside of your home, there is minimal disruption to your daily life inside the property.
Protects Your Home: The added layer of insulation and render protects your home's exterior from weathering and can help prevent inside condensation.
Increases Property Value: A well-insulated home with a modern exterior finish is more attractive to buyers, which can significantly increase its market value.

How does external wall insulation work?
External wall insulation works by adding an extra layer to the outside of your house. This layer helps keep the warmth inside during the winter and keeps hot air out during the summer.
After the insulation is added, the walls are covered with a new smooth surface to make everything look like new. This helps your home stay comfortable and saves you money on your energy bills.
