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.

What do air source heat pumps look like and where will they fit in your house?

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.

How It Fits in Your Home

How It Fits in Your Home: External wall insulation is the ideal solution for properties with solid walls, typically built before the 1920s.


  • Appearance: This solution will change the external appearance of your home, which can be a great way to modernise an older property.


  • Space: Unlike internal insulation, this method does not reduce any of your valuable floor space.


Process: Our advisers will conduct a thorough survey to ensure your property is suitable for the installation. The project is managed from start to finish on the exterior of your home, ensuring a smooth process with minimal disruption.
