Plumbing- 7 Aug 2018
I gave this person the plumbing work for my house extension and renovation for the existing of the house, at first this person was polite and well behaved, after he was given the first instalment, his intentions became clear. The contract, which was signed by both of us, was ignored. it was allegedly written by his 17 years old son, who left them and that the man is not responsible for the contract. Whilst the man and his brother were doing the plumbing a few things which were lying around the house had gone missing, as well as the fact that he had just spontaneously disappeared for two-three weeks at a time on multiple occasions. In each occasion he had brought up excuses such as his wife had a heart attack or he had been to Poland for a bereavement. Towards the end his attitude had changed as he became more aggressive. He had persuaded me to give the last installment and promised to be devoted to the task at hand. As soon as I entrusted him with my hard-earned lump sum from my pension he took his tools and left, resulting in me having to find other tradesmen to do the remainder of the work. In his profile he advertised that he has a diploma and many other qualifications in plumbing, I have my doubts as he could not hold a basic conversation in English. This made me suspect whether he really did receive these “qualifications”. His work had many faults within it which forced me to turn to another plumber.

Loft Conversion- 29 Apr 2023
My house was totally renovated by this company. I was very satisfied with much of the work. I was informed that I would be given the buildings certificate and the electrical certificate for works completed once final payment was received. I was given the buildings certificate. I was not given the electrical certificate, although the house had been fully rewired as part of the work. I chased up for the certificate but my requests were ignored. I was aware an electrician had come to inspect the works, and the builder who had been on site indicated it appeared to go well. I have now just recently had the electricity in the house inspected by an electrician and have found there were issues that required rectifying.
