I reported to my insurance company in March 2022 a leaking water supply pipe. They told me there was no need to turn off the water and then took 3 months to mole a new pipe. The water company told me they would then put a new connection in the kerb free of charge as the old one was lead and this would be within 15 days. 2 months later I had to call them to ask what was happening as they hadn't done anything and water had been running under my home's foundation for 5 months. The water company official said "there was no pleasing me" and I was "complaining about the state of my foundations". I have copies of the emails containing this information which I requested through Freedom of information. 2 years on and my plumbing and drainage has collapsed flooding my crawlspace and my walls are cracking and making noises. Paths have sunken down and brickwork covered in efflorescence. I turned my water off 3 weeks ago. I am absolutely terrified my home will collapse. I've sent a complaint to the water company and they are going to investigate but should I appoint my own structural engineer? Thanks for any help anyone can give me.
