this trader did not complete his work took all of the money then disappeared!! he has been in contact a few months later apologising ,he said he had a mental breakdown. He asked me how much out of pocket i am. It came to about £4000 because i had to pay his subcontractor on my job so that they would continue and finished their work in my house. An electrician found serious dangerous work on a electric power shower. I have since had the system change to a shower where hot water comes from a cylinder. therefore we had to dismantle his installation.
