J was very professional and friendly and despite the broken lock being awkward, he got it out and replaced it. It is now working perfectly with literally no sign he was ever there! Highly recommended

John at Quebuild went above and beyond for us on this job. He completed all the work in a timely manner and for a very reasonable price. He was super knowledgeable and extremely attentive to detail, making sure to leave a high quality finish in terms of decoration - and he came back afterwards to address a few small things that needed doing. He was also a pleasure to have around - and I would highly recommend him for any other work. 10/10.

Felix did a fantastic job at upgrading my Consumer board or the fuse box and provided me with the EICR report at the end. I was apprehensive at first as I spoke to so many electricians and got so much info mixed up. Felix is very experienced and explained with clarity, which put my mind at ease. The job was honestly priced and within my budget. He is friendly and conscientious. Tidied after himself. I will definitely recommend.
