Services
Cavity wall insulation provides a reliable way to make your property more energy efficient. The insulation is inserted between external wall layers, significantly reducing heat escape and helping to maintain a consistent indoor climate. Customers often notice immediate benefits, including lower energy costs and a warmer home environment. Installation is completed efficiently, usually within a few hours. 
At INSUL8, external wall insulation serves as both an energy-saving measure and a visual upgrade for your property. It helps stabilise indoor temperatures and provides a reliable way to cut energy consumption. In addition to practical advantages, it can enhance kerb appeal and raise property valuation. Typical costs depend on building specifications. 
We specialise in delivering efficient loft insulation that helps retain heat, cut energy use, and enhance indoor comfort. Our process involves applying thermal barriers in the loft area, tailored to your propertys specific needs. It's a cost-effective solution that supports environmental goals while reducing condensation and the risk of mould in the home. 
Our Energy Performance Certificate service helps property owners meet legal obligations while understanding their buildings energy profile. The assessment analyses elements such as insulation, heating, and lighting to provide a clear rating. Recommendations included in the report offer cost-effective ways to improve efficiency. With upcoming rental regulations, securing a compliant rating is more important than ever.

Had cavity wall insulation installed, James was really helpful throughout the process, the survey was completed very professionally, the installers arrived on time, were very approachable, explained the procedure and left everywhere clean and tidy, received the 25 year insurance backed guarantee within 4 days, would definitely recommend Insul8, hence this review.

Insul8 are a fantastic team, they helped do a survey, provided a quote quickly (explaining different options they could do) and swiftly sorted a date to complete the work. They were a delight to work with and we would absolutely reccomend them. Guys that did the job were friendly, fast and cleaned up after the work was done. Really appreciated it!

Excellent service from James and the installation team at INSUL8. They clearly explained the process, surveyed the building and checked the efficiency ratings before providing a quote. On acceptance of the quote they gave an install date. The install team were on time, introduced themselves and explained what they would be doing. On completing the work they cleared up after themselves. Overall a good company to deal with who know what they are talking about.

I contacted Insul8 in advance of my 3rd house renovation. Whilst they couldn't help me specifically - one of the team was more than happy to take time out of their day to discuss my issues and project and give impartial advice. I wish more people were helpful to those seeking advice when they don't get technical jargon!

Insul8 did my cavity wall insulation. The initial survey was done promptly and professionally by a very friendly and knowledgeable guy.
I was quoted a price by James and was satisfied with it. The work was carried out professionally and no major mess was left. The guy putting in the insulation was very amenable and he agreed to fill in a couple of holes on the exterior of my house at no extra charge.
Well recommend INSUL8 as a reliable company.

INSUL8 reorganised the entire replacement and installation of new storage heaters through out my home, after I had been bitterly disappointed and utterly let down by a different eco company.
INSUL8 are 100% reliable, contactable and professional.
From James in the office to the chaps that completed the installation I was treated with respect and so was my home.
I cannot thank them enough.
I wish I had found them first.
100% RECOMMENDED.
