"we got various quotes for our loft straight away Colin stood out to us, he was straight up about costs and timings and did not try to sweet talk us like others. Colin and Paul were always on hand to answer questions and give advice on the build. What you are quoted is what you pay with this firm which is important, they are also very flexible if you want to change something or dont like something they will be upfront with how much this will cost before altering anything. They are literally around day or night, we had a slight leak come through from heavy rain in the night, quick call to Colin and he drove over right away and was up the roof and fixed the leak - also painted the room free of charge. The level of work is quality and we are so happy as a family of 5 with our new loft conversion. We will definitely use Colin and his team again when we are ready to do our rear extention and advise them to our friends and neighbours 1 of which have already started accross the road."

"Colin and all his guys at Lofts of London are a pleasure to deal with. They have done two major extensions for us now, a loft bedroom in 2023 and a side return and new kitchen finished January 2026 and we are so happy with the results. Colin makes the process as easy and transparent as possible which was important for us given that building work is a huge investment and costs are going up all the time. No complaints or issues with quality of the work and he and his brother Paul were able to come up with solutions for issues that arose along the way. I have already recommended Lofts of London to friends who are also very pleased with their completed projects. If you are looking for a reliable, family run company who will deliver good quality then do give Colin a call (though he is very much in demand!) Thank you Col we are so pleased to have chosen your firm"
