Upgrade your home’s energy efficiency effortlessly with NexGen Energy Group. Our ECO4 scheme offers cavity wall insulation to help you combat draughts and reduce high heating bills. Cavity wall insulation is a cost-effective way to enhance your home’s thermal performance. It involves filling the gap between the two layers of external walls, which is a common construction feature in houses built after the 1920s.
To determine if your home has cavity walls, you can inspect the external brickwork. Cavity walls typically display a uniform brick pattern with all bricks laid lengthways, as opposed to solid walls where bricks are arranged in alternating patterns.
NexGen Energy Group provides efficient cavity wall insulation services to enhance your home’s energy efficiency. Our registered installers drill small holes in the exterior walls and inject insulation materials, such as mineral wool or polystyrene beads, to fill the cavity.
The entire process typically takes about two hours for an average-sized house, ensuring minimal disruption to your daily routine. While the cost varies depending on the size of your home, these expenses can often be recouped within five years through savings on energy bills.
Reduce Heating Costs: Save as much as £515 per year (according to the Energy Saving Trust) while maintaining a consistently warm and comfortable home throughout the year.
Improve EPC Rating: Enhance your home’s Energy Performance Certificate (EPC) score, making it more attractive to potential buyers and potentially increasing its market value.
Promote Environmental Responsibility: Lower your carbon footprint and support environmental well-being by reducing energy consumption and greenhouse gas emissions.
To qualify for standard cavity wall insulation, your home must meet the following criteria:
During the assessment, the installer will determine suitability and may use mineral wool or polystyrene beads for insulation. For houses with narrow cavities or flood risks, polyurethane foam may be used, and specialist installers will manage the process. If internal walls exhibit damp patches, it’s advisable to address these issues with a damp prevention specialist before installing insulation. Additionally, cavity barriers are installed in homes sharing walls with neighbours to prevent interference.
For flats, insulation requires agreement from all occupants in the block, as individual flat insulation is typically impractical.
Highly recommended! Great job done in excellent time. Nice team of guys, polite and friendly and left the property immaculate. Did exactly what they said they would without any catches, really is 100% without any cost to the customer, just a few cups of tea is all it cost me and my house is now fully insulated. Very happy.
So glad I found this company online. My house is so much warmer now and saves me loads on my bills! Which we definitely need at the minute with the cost of living crisis and everything else going up in price. Thanks so much NexGen.
