Castle Water are a completely incompetent organisation and if you have any choice at all - do not go anywhere near them. I am the Treasurer of a church in Clapham SW4 and while we try to be patient with all our suppliers, we reserve the right occasionally to throw everything at them. Having spent two years trying to switch to metered billing (to help them, and the world), we finally got that sorted this month March 23. We got a corrected bill, with a letter telling us they had a new bank account. So we immediately paid that bill to the new bank account and also cancelled our existing Direct Debit to the old account. A day or so later we got a £48.24 bill from CW for cancelling our DD. You couldn't make it up. Called them today to complain but no interest whatever in helping us. What is really annoying is that in the meanwhile I have sent them a form to set up a new DD to their new account; but I wish I hadn't. As others have mentioned this company is just a desktop robbery outfit, which does nothing actually to supply water or fix anything - and thus should be closed down ASAP. I will now be making a formal complaint to CW and will not let up until we get to OFWAT and get them closed down. Basically a criminal gang of some sort.
