Mark responded to my post quickly, arrived promptly, and sorted the problem rapidly, with a high level of knowledge and workmanship. He was also thoroughly pleasant to talk to on top of that! I would definitely use his services again.
The plumber has visited and the job has been discussed. However, I was buying the appliances after this and needed further advise on what is suitable to buy. I texted but have not received a reply over 24hrs. No explanation, my purchase was delayed because of the delay (while the toilet is leaking!). Then I received an irrelevant message (as if nothing has been discussed) via Mybuilder. I wouldn't trust such a contractor
