DO NOT USE THIS COMPANY!!! Or you might not have an option!! The water industry should be ashamed of its lack of control over companies that are using out dated information to make money. If I could I would award them less than one star! DO NOT SIGN UP TO THEM. Out of the blue we get a bill, no metre reading no visit generated from a computer. Called and explained that we do not have a toilet or a sink and that the water has been switched off for 5 years. Then we get threatening letters telling us bailiffs will be actioned and that interest will be applied. After calls and emails which resolved nothing we contacted Resolve (where the case is still open) and asked them to intervein, they have helped, however nothing was getting resolved. So we had to switch to another company to resolve the matter. Castle water owe us money and informed us it will take months!! to process us. They use tactics which in any other industry would not be accepted. My advise is use any other company other than Castle Water.
