I contacted David at HnD Plumbing because he is local to me. Communication, on line, was quick and easy. Explained what I wanted and sent pictures of the current installation after which David gave a quote and a time scale of a few days, which was ideal. He arrived today, as agreed, and undertook the job which was a challenge but he persevered and managed to remove the very old taps and fitted the new set adding isolation valves on the pipes. Great job, well done. Highly reccommend this excellent plumber.
