I found Comfort Solutions through their website. I contacted them and they came very quickly to give a quote on the day and at the time that was requested. Our loft, although lagged was not up to current specifications. After some discussion we decided to just have our loft properly and fully insulated, which was not easy because we have 30 sunken lights for which insulated boxes had to be made. The fitters were very pleasant and efficient and even put down pieces of carpet to protect the floors from the dust and dirty boots. We are very satisfied with the quality of the work done and although not the cheapest, we would certainly recommend Comfort Solutions and use them again.
