We used Surrey Lofts last late last year and could not recommend the team highly enough. They made the entire process easy and their forms of communication were outstanding (setting up WhatsApp Groups, emails, etc.. Everyone was contactable 24/7 which is an unbelievable service. A special thank you to Pete who was our Project manager who was outstanding and took our calls even at weekends and the girls in the office. Thank you for the great work and the great finish. So pleased we made the decision to use Surrey Lofts.

We are utterly thrilled with our new loft space and thank Surrey Lofts for all their hard work! We had a terrific experience throughout, and appreciated the advice from the team and our project manager Leigh during the build. Everything was completed on time and with minimal disruption to the rest of the house. Would certainly recommend!

We've had an awful experience with Surrey Lofts and Mark Grimshaw! Stay away from this company!

I've attached photos of what they considered the finished project. They did a terrible job on our loft extension, then when we were on holiday their plumber flooded our downstairs and destroyed our back room. They're now denying any liability and we may have to take them to court, as the damage is extensive. One of the worst things was they actually stole money from our child's charity jar (yes we have evidence). The process was terrible, the project manager useless, zero communication

We have been enjoying the 2 new bedrooms and ensuite bathrooms in our loft conversion for almost 4 years. From start to finish and subsequently Mark and the Surrey Lofts team have done a great job. The build went according to plan, despite a period of severe storms and winds, and was kept within budget. I was constantly kept informed of progress and consulted on decisions big and small. I was very pleased with the design of the new staircase and landing, which we needed to match to a feature stairs/ gallery landing in the main part of the house. We wanted it to look like a natural continuation

I used Surrey Lofts after being recommended by a friend and I can honestly say from start to finish was a very professional experience. Nothing ever seemed to be too much trouble and I was constantly informed of the progress at all times. Workmanship was of the highest quality and the main section of the house was kept nice and tidy whilst the work was going on and finished on schedule. Overall a great service. Would highly recommend.

We have just finished a loft conversion with Surrey Lofts. I have to say the finished result is great, but the journey to get here was not quite as easy as they promise! The guys that were actually doing the work were fantastic, hard working, good quality work etc. The conversion itself has been great, but it has caused some damage to the rest of the house, all of which I was told that is outside of our contract to fix. For example ceilings with big cracks on the first floor. That isnt the sales line from Mark who tells you everything will be sorted. In the end the builder fixed everything
