Chris made booking easy, expectations were clear, so I knew what I was getting for the quoted price. David, Gareth and the team arrived on time and were polite and tidy and did a great job. Nothing to fault, really happy with the experience.

Our home roof space had a lot of condensation build up over the winter and the team provided us with the best solution to combat the issue. The price was very competitive and very affordable with a great quality of workmanship. The installation of the roof vents took less than an hour. The installers communicated further advice to help improve our loft insulation to maintain a proper cold loft system. Thanks to the team today!

We had a survey done by Dave. A great price for a large loft and within the week we had insulation laid and roof vents installed. A competent, respectful, chatty and friendly attitude throughout. These guys know their job and they do their profession proud. I'd recommend them heartily. A job well done. McDowell of Newtownards.

Office staff were very helpful and arranged the installing very quickly. Dave and Thomas who carried out the work were very efficient and did a really good job. I would highly recommend Clever Insulation.

I had loft insulation work carried out under the affordable warmth scheme. The guys were great to deal with and carried out all the work with no fuss. I agreed a date and they arrived on time and carried out the work very quickly and efficiently. Would have no problem recommending this company.

We needed to fully insulate our loft and Clever Insulation were very quick and easy to communicate with and gave us a really good price! They came out so quickly and were very efficient in completing the job. They were also very clean so very little clean up required :)
I would highly recommend Clever Insulation to anyone looking for a reliable and efficient company.
Thanks so much!

Very satisfied with the standard of work, efficiency and customer service provided by Chris of the Customer Care Team - insulated and installed air vents in my attic on Friday. Five star service from beginning to end.

Chris, David and the guys did a brilliant job insulating my loft and installing roof vents. From start to finish it was a smooth stress free process. They are great workers; neat, tidy, professional, good timekeepers and communication with Chris was excellent. I can't praise them enough. The work was carried out quickly, efficiently and expertly. I would 100% recommend them.

Was a little bit weary of spending money on an update for my house due to the cost of everything now but I am so happy I made that decision. My loft was letting out so much heat, I can't imagine how much I've been overspending on gas all these years to keep my house warm. At first I was going to go for spray foam for my loft but after some research and conversations with friends I found out it's extremely difficult to sell your house if you have spray foam.
In my research I found Clever Insulation, the staff there were quick on getting back to my online message and organising a meet up for the installers to go over cost and a timeline. Everything was done within a few days and I could instantly feel a difference in my house. 10/10 would highly recommend you get in touch with the guys here if you're looked to get insulation in your house!
