Disgusting company

Where do I begin? Huge bill appears out of nowhere despite the fact I am already paid up to date with Southern Water and have been since 2018.
All started in February and still ongoing. Bill gone up by £1000 because I am not paying for my water twice!
Incredibly rude on the phone, closed my case when they deemed it ready to close even though nothing is resolved. Lied about having correspondence with Southern Water. Caused me sleepless nights and no end of stress and still they continue to send huge bills.
Horrible company who dont care about you at all - I never even entered a contract with them as am very happy with Southern Water. They appeared completely out of no where. AVOID AT ALL COSTS!!!!!!!

Castle Water - Toxic Profit Culture

Castle Water operate a toxic culture designed for maximum profit at the expense of their customers. They bill based on inflated estimated readings, even though they have access to actual visual readings. Their customer services approach is one of deflection rather than transparency. In many years in business I have not come across a business with such shady practice and disregard for the law, regulations and customers

I'm very concerned about your experience, as we do everything we can to produce accurate bills based on actual meter readings. I've sent an info request via TrustPilot - if you can reply with your account number I'll look into this as a matter of urgency.

Our company received out of the blue several invoices for our waste water that we had no knowledge of. SES water had sold that part of our service to Castle Water without our knowledge, who then opened an account without our permission. I tried several times to contact customer services via phone (no one answered) and via chat which then timed me out on several occasions. I finally raised a complaint and Sarah Byers, a customer service agent responded. I found her to be very helpful and efficient and we have finally resolved our issue. Castle Water need more employees like Sarah.
