I had a new bathroom toilet installed with a multi flap in the waste pipe. I was quoted a reasonable price for the work which was carried out promptly on a day to suit me. Aziz and Kebba carried out the job to a high standard. I’m very pleased with their work and the end result. I found them professional, polite and pleasant to deal with. I will definitely use them again and would recommend to others.

Having been let down by another plumber Aziz did a fantastic job - coming out at the weekend to do the job. Lovely guy, quality job & fair price considering it was a weekend. Would definitely use him again!

Aziz was just brilliant in every way. He was courteous, professional, hard working and reliable, as well as being friendly and very customer focussed. He spotted and sorted out some issues left by the installers of the old boiler, and he kept me completely informed about his progress. He was also faultlessly tidy and left everything in ship shape order. He kept his promises, deserved my trust in him and took all the potential stress out of the process. I can't recommend him and his company more highly. I found his company via Which? Trusted Traders and wondered if all the glowing reviews could be true. They are!
