I got a call from a plumber to price up a job for a 8.5 kW shower. So I went and had a look, told him could be a complete rewire here mate. He and the customer not pleased at this so I told them I will have to do some tests. Plumber says no no dont do that. I said I have to, and it will need a board change anyway. So he and the customer, went through the cable run route, about 18 metres and a right pig. Then the plumber told me he will supply materials, give him a list and I gave him a rough quote there and then. He said I,ve already quoted the customer less than that. He then got really agrressive dont you want £150 blah blah blah. For the fact he got nasty I said yeah I'll do it. He said great be here tommorow at 7. I have just got a call from him " are you coming dont you want £150 " I told him never to ring me again and put the phone down. A new shower cct and board change for £150 what an Nutter.
