Fantastic job from start to finish, great advice on what we needed, really friendly guys, super professional, turned up on time, no mess and we can tell the difference already!

Really pleased with the top up of our loft insulation. Would definitely recommend them. Inspected and advised by James as full replacement was not needed and not pushy as with some companies who would have talked us into having a full replacement. Jacob and matt arrived on time and were very polite and respectful of the property and vacuumed the hall after completion. Thank you.

Insul8 were excellent - from the beginning (site visit and prep) to completion of our EWI works - the standard of their work was very high and they were very friendly, respectful and co-operative with us throughout the building process. We would strongly recommend them to others considering EWI works to their home.

Great, professional and friendly service from start to finish. We agreed what needed doing (and just as importantly what didn't)! job done in a few hours with minimal fuss and quality Knauf product at a reasonable price. Thank you

Matt and Jacob did our cavity wall insulation today. They were helpful, pleasant and worked quickly and efficiently. Explained the process fully before they started and cleared up after. Couldn't ask for more. First rate!

I would highly recommend this company. James and Matthew have gone over and above expectations in every way. They have been efficient, courteous and so very helpful in addressing all my questions and I have nothing but praise for them.

Great service. Insul8 completed a large & complicated roof insulation job very efficiently and with minimum fuss. Friendly and helpful team. Would definitely recommend.

James and the INSUL8 team are great. They did for a cavity wall survey of our house as I thought we didn't have any and needed a new EPC. James organised for Jonathan to come out within 48 hours and he was polite, thorough and took the time to explain to me what he found in each of our walls. Subsequent customer service has been brilliant. I would highly recommend INSUL8 to anyone.

Absolutely brilliant first class job by first class workers couldn't tell they'd moved anything as it was all put back & everything cleaned up highly recommended 5 star

Insul8 have been an amazing support for us whilst dealing with major insulation issues. There is a level of integrity and care with Matt and James that we have rarely seen in other companies. They are genuinely working to give the best possible rather than being driven by purely commercial concerns. In a time when we have had to negotiate major damp, mould and insulation issues and where other companies have been less than ethical, Matt has provided a lifeline of support and information to help us navigate our way through. Thank you Insul8 for being there!

Matt and Jacob done a excellent job insulating and boarding my loft also doing some work on internal doors they were both polite professional and respected my property

This company dealt with my Loft Insulation in a very professional manner, efficient, clean and polite. I would recommend their service.

Recently had the loft insulation redone and the loft re boarded by James, Jacob and the team. They came when said they would, were very courteous and considerate with regards noise and tidied up before they left and done a great job. They even came back another day to finish off the boarding when I needed to have a leaky pipe replaced so the there was no problems down the line. Very happy with the work and the price. Happy to recommend Insul8.

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 quote to job done. Great people to deal with at every part of the journey, can't recommend enough, really happy.

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.

Insul8 came and did a loft insulation inspection and a quote. But when Matthew and Jacob came they went into the loft and tidied up the insulation and added a little more and that was enough and didnt take too long. Finally they vacumed where they had been. James phoned me and said there would be no charge as not a lot of time was needed. Delighted-do try them. Jonathan

Matt and Jacob have just been to do my loft insulation, good workers and very pleasant, no mess at all

Excellent service from first contact to survey to job execution of cavity wall insulation. Would definitely recommend. Matt and Jacob were very good, job finished with a good clean up leaving no mess or damage

After struggling for ages to find anyone willing to do cavity wall insulation on a tiny extension, these guys were happy to do a very small job at a very reasonable price and were lovely and very tidy :-

Great local company who really know their stuff. Friendly, approachable and always contactable. Properly skilled tradesmen who also cleaned up after themselves. Definitely recommend and would happily use them again

After receiving 5 or 6 quotes from various companies ranging from 1500 - 7500 to insulate my disabled parents bungalow I decided to contact INSUL8. All I can say is how glad I am I did. Matthew, James, Jacob, from start to finish were respectful, punctual, and trustworthy. They made my parents feel comfortable having the guys in there home and when Matthew found an issue half way through, he provided a solution, came back the following week with a different colleague and completed the job at no extra cost.

I honestly cannot speak highly enough of this company they have been absolutely brilliant from beginning to end and have made my parents very happy. It's a shame there aren't more companies like this. I will definitely be passing your details on. Thanks guys.

Insul8 sorted us out with some Cavity Wall Insulation and we couldn't be happier. They were efficient, friendly and explained clearly what they were doing. We've felt the benefits immediately and would definitely recommend getting it done if you're thinking about it.

We have just had our loft re-insulated & re-boarded by Matt, James & Jacob at INSUL8. Our property is old with the loft filled with lots of rubbish that had accumulated from previous owners. It also required the existing boarding to be removed to install new insulation where none existed, so not a particularly straightforward job. They started on the agreed date which was important as we had taken time off work specifically and tackled the job efficiently & professionally over a couple of days, always clearing up and leaving us entirely satisfied with the new insulation and boarding that we required. I would certainly recommend INSUL8.

INSUL8 completed our loft insulation recently - a thorough job, arrived when they said they would, cleared up and left the house in a tidy state, would recommend for similar work.

Answered all our questions, made time for our job very speedily. House now much warmer and energy use down. Thanks v much! Services Service not listed. More

Fantastic company and brilliant staff. Had external solid wall insulation installed by insul8. The team consisting of Lewis, Rourke, and gaffers Matt, James and the Romanian insulation/ rendering team, are true professionals with a keen eye for detail. Nothing was too much bother, always kept informed at each stage of the process. Site was left clean and tidy on completion and external wall fittings were restored for me. Lewis, Rourke and Matt even worked on Saturday and Sunday, and one occasion were working from scaffold in a torrential thunderstorm to ensure there would be no ingress of water by covering over the exposed roof which had slates removed to extend the roofline to allow the insulation to be fitted I'm really happy with the finished product and have had numerous positive comments, some even saying that it is "the best house on the street". First 2 photo's are before work commenced and the other 3 are when the job was completed. I would definitely recommend Ins

Insul8 installed new loft insulation for me. They were easy to communicate with, helpful and their installer was a really friendly guy who took the trouble to explain what he had done and to borrow our vacuum cleaner to ensure that he had not left any mess. Services Service not listed. More

They really do care about the quality of their work and ensuring customers are happy with the results. I can honestly recommend them to anyone looking for insulation. Thanks again guys!

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.

James was incredibly helpful, and even though we didn't go forward with them in the end his company appeared to be genuine and trustworthy. If we have any insulation completed in the future I would go with this company. Thanks so much

Had my loft insulated. Installation team turned up on time and cleaned up after themselves. Showed me before and after pictures of the finished work after they had finished. Would recommend.

Insul8 completed Loft Insulation to the government standard 270mm. They were prompt to answer my initial query and give me a quote, and when this was accepted, to arrange a date for the work. They were flexible in accomodating me when I asked them to put back the work for a week to fit in with other work on the house being delayed. On the date for the work I was phoned to ask if the technician's arrival could be delayed by twenty minutes, and he then arrived promptly as rearranged.

He was well mannered and got to work without delay, protecting my carpet by wearing overshoes. He worked steadily for a couple of hours without a break before asking me to inspect the work and explained certain aspects of it. The material used appears to be natural, rather than glass fibre. The young man was a pleasure to have in the house.

The team at Insul8 Ltd were fantastic from start to finish. I had my loft insulated by this company and I am delighted with the result. Insul8 Ltd conducted a thorough survey, priced the work and then installed the insulation, leaving no mess at all. Immediately after the insulation was fitted I could feel the difference!
