Review by Phil

"We are extremely pleased yet again with everyone at Lofts of London following the completion of our new loft conversion and garden room. We previously used them for our extension in 2022, and the planning, attention to detail and quality of the finish were exactly what we were looking for. Once again, we were not disappointed. The whole team were polite, respectful and amazingly quiet throughout the works. They worked incredibly hard, even through the recent heatwaves, and nothing ever seemed too much trouble. A special thank you to Colin and Frankie for all your help. It’s so nice to have friendly points of contact and to know that any questions or queries will be dealt with straight away. We will most certainly be recommending Lofts of London to friends and family in the future and would have no hesitation in using them again. Thank you, Colin, for delivering yet again. We are extremely pleased with the finished result!"

"Colin, Paul and Frankie and there team did a fantastic job on our loft conversion and kitchen extension, which was completed at the end of July. They were prompt, tidy and knowledgeable throughout, and any issues that arose were dealt with quickly and professionally, all the costings were clear and no hidden surprises. We’re really pleased with the finished result and would happily recommend Colin and his team."

"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."
