Does my home need cavity wall insulation? 

Determining if your home needs cavity wall insulation involves checking a few key factors. Homes built between the 1920s and 2000 are likely to have cavity walls that may not be insulated (properties built after 2000 were constructed with insulation in the cavity, due to changes in building regulations). You can also look at the pattern of your exterior bricks; if the bricks have a regular pattern (with all of the bricks laid lengthways), your home likely has cavity walls.

Cavity wall insulation grants offer a fantastic opportunity to enhance your home’s energy efficiency and comfort, providing a host of benefits over properties with uninsulated walls. Here’s why you should consider cavity insulation:

Lower Heating Bills: Installing cavity wall insulation significantly reduces heat loss, leading to lower energy costs and improved home warmth.

Smaller Carbon Footprint: Cavity wall insulation makes your home more energy-efficient, cutting down carbon emissions and lessening your environmental impact.

Enhances Home Comfort: Proper insulation ensures a consistent temperature throughout your home, eliminating cold spots and drafts.

Prepares Your Home for the Future: With rising energy costs and stricter environmental regulations, homes with cavity wall insulation are better positioned to meet future energy standards affordably.

Cavity wall insulation grants provide a cost-effective way to upgrade your home, making it warmer, more eco-friendly, and prepared for future energy challenges.

How does cavity wall insulation work? 

Cavity wall insulation works by filling the gap between the two layers of an external  wall with insulating material, effectively stopping heat from escaping your home. This insulation acts as a barrier, preventing the warm air inside from cooling down by reducing heat transfer through the walls. As a result, your home can retain heat more efficiently, significantly reducing the amount of energy needed to keep it warm.

With cavity wall insulation grants available, you have the opportunity to enhance your home’s energy efficiency and comfort without the financial burden. Energy Saving Grants is here to guide you through the benefits of cavity wall insulation and help you access the grants you’re entitled to.
