Cavity wall insulation is a highly effective way to improve energy efficiency in Merseyside homes, particularly those built between the 1920s and 1980s. By filling the gap between exterior walls, this upgrade reduces heat loss and lowers energy bills.
Through ECO4 and GBIS, eligible households can access free cavity wall insulation, making it a cost-free solution. At Warmr, we help Merseyside residents unlock these benefits. Here’s why cavity wall insulation is a must for your home.
What Is Cavity Wall Insulation?
Cavity wall insulation involves injecting insulating material into the gap (cavity) between the inner and outer walls of a home. This creates a thermal barrier, preventing heat from escaping and keeping your home warmer for less energy.
Many Merseyside properties, especially in areas like Liverpool and Wirral, have cavity walls that are uninsulated, leading to high heating costs.
Benefits of Cavity Wall Insulation
1. Reduced Energy Bills
Cavity wall insulation can save up to 35% on heating costs, equating to £150–£350 annually for a typical Merseyside home.
2. Enhanced Comfort
Insulated walls eliminate cold spots and draughts, creating a consistent, comfortable indoor environment.
3. Environmental Impact
By reducing energy consumption, cavity wall insulation lowers your carbon footprint, supporting Merseyside’s sustainability goals.
4. Health Benefits
Warmer homes reduce damp and mould, improving air quality and reducing health risks.
5. Quick Installation
The process is non-disruptive, typically completed in a day by Warmr’s accredited installers.
