I can recommend: British Plumber
I have spent my working life in the building trade and was fortunate to see in the free press Dave Farr plumber for my water leak which was at a high level in the corner of my lounge I exposed the pipe and it was an elbow joint which had developed a crack in it The pipe was surrounded by electrical wiring, when Dave arrived I could see that he knew what to do and immediately started work and soon had it fixed I could not have been more pleased with him or his very reasonable price which also surprised me I made good the plasterwork myself and I have had no more trouble from it.
