EXCELLENT Based on 1845 reviews Posted on Google Rebecca WilliamsTrustindex verifies that the original source of the review is Google. We are providing this review on the day of installation. We had DPC Plus installed. Installers arrived on time, were professional and completed the work to a good standard.Posted on Google Michal KvočekTrustindex verifies that the original source of the review is Google. I had a survey carried out to check for a possible damp or mould issue in my flat. The surveyor (Johnny) was very professional, thorough, and honest. After a careful inspection, he confirmed that there wasn't a problem they could help with. I really appreciated his approach because the survey was free, and he could have easily tried to find an issue that wasn't there. Instead, he was honest and gave me some genuinely useful advice on how to prevent future problems. I would definitely recommend their service.Posted on Google Andrew HattonTrustindex verifies that the original source of the review is Google. From survey to completion the service was excellent.

How long does cavity wall insulation last?
When correctly installed, cavity wall insulation can last for decades. At Home Energy Save GB, we use approved materials installed to strict industry standards to ensure long term durability. Performance longevity depends on factors such as exposure to weather, wall condition and correct installation methods. That is why our survey process is so thorough. By ensuring your Liverpool property is suitable from the outset, we protect both performance and lifespan. We also provide guarantees for added peace of mind.
Will cavity wall insulation cause damp in my home?
Properly installed cavity wall insulation should not cause damp. Problems typically arise from poor installation, unsuitable properties or pre existing moisture issues. At Home Energy Save GB, we carefully inspect every Liverpool property before recommending insulation. We check for cracks, pointing defects, blocked cavities and exposure risks. If your home is not suitable, we will tell you. Our priority is long term building health, not just installation. When done correctly, insulation improves comfort without increasing damp risk.
Will I notice a difference straight away?
Yes, most homeowners report improved warmth very quickly. At Home Energy Save GB, many Liverpool customers tell us their home feels more comfortable within days of installation. Walls retain heat for longer and rooms feel less draughty. While energy bill reductions are seen over time, the immediate improvement in comfort is often noticeable. The key is correct installation and material choice, which is why our survey process is so detailed and thorough.
How much does cavity wall insulation cost in Liverpool?
Costs vary depending on property size, access and insulation material. At Home Energy Save GB, we provide a free, no obligation survey and detailed quotation tailored to your Liverpool home. We believe in transparent pricing with no hidden costs. While every property is different, cavity wall insulation is widely regarded as one of the most cost effective energy efficiency upgrades available. Long term savings often outweigh initial investment.
Can cavity wall insulation increase my property value?
Improving energy efficiency can positively influence property value and buyer appeal. At Home Energy Save GB, we often see Liverpool homeowners benefit from improved EPC ratings following insulation. Energy efficient homes are increasingly attractive to buyers concerned about running costs. While insulation alone does not determine value, it strengthens your property’s overall efficiency credentials and comfort.
