“I have just changed from Castle Water best thing i have ever done. Kept sending conflicting bills, charging for water i had not had , sending debt collector letters when bill had been paid in full list of problems to long to write. All these other bad reviews cant all be wrong.”

“We had a monthly direct debit which they stopped collecting. We had plenty of money in our bank account and the direct debit is still active - but the money just wasn't taken. Then we got a threatening letter, saying that they were involving a debt collection agency, in the same envelope as they said they would take payment for the rest of the year by direct debit. No response to my subsequent correspondence to them. Worst customer service I have ever encountered in business. In process of changing supplier.”

“The most useless, incompetent, and unprofessional company that we have ever had to, unfortunately, have to deal with. We have a wrongly invoiced and billed for over 11k in JANUARY. The actually used amount was more 200-300 GBP. We have spoken to almost every single customer service advisor (Mark K, Sam K, Lynne C, Kat C, Sam S, Mohammed, Hassen K......) and to date even though they have admitted they have made an error and falsely charging us for 3000 units of water WE DID NOT USE, we have received yet another threatening letter of further action and penalties THIS MORNING! This is mentally tormenting creating unnecessary distress and harassment. One star is one star too many !!”

“After about a dozen emails, many chats on the phone after waiting 30 minutes plus each time I had been promised they would sort out my invoice. But no, they still have not. I received a letter chasing payment within 14 days. I decided to pay this and continue trying to get my invoice sorted. I paid within the 14 days of their letter. But also with the 14 days they imposed interest and a £40.00 late payment fine. Their on line chat is a total waste of time, you fill in all the questions and then it says busy or times out. They definitely are the worst company that after 40 years in business I have ever had the misfortune to deal with.”

“Quite possibly the worst experience I have had dealing with any company in 38 years in business. They are incompetent, intransigent, unhelpful and simply do not listen. When they are proven wrong no apology or compensation is forthcoming. A truly dreadful company. Avoid at all cost.”

“This is awful customer service, no one ever get back to you, all they do is keep sending bills when you have an issue to sort out”

“My comments are the same as that of Colin. After 2 years of absolutely no contact I had a bill for £3.79. This I paid straight away. However they added 9 pence interest! I have now a month later had another bill and letter threatening with using debt collectors for the 9 pence and another penny interest making it 10 pence in total. They are a disgrace. I gave up 2 years ago of speaking on the telephone and reverted to emails. Now they dont even bother to answer emails and just send automated bills. As Colin said - they are the PITS!”

“Absolutly awful customer service. Send me an estimated bill for £3200 and when I say its waaayyy too high they need to come get the meter read, they say they cant send engineers out due to Covid (even tho meter is outside in the footpath) and I have to pay it ontime or incurr penalty charges!! No help, no give just a scripted unreasonable response!”

“They are the Pitts! all the comments are exactly the same as I experienced, I managed to rid myself of them in 2017 and went with everflow water no problem and a quarter of the price and have no problem with them. I have just had a bill from Castle water July 2020 for £3.97 + interest of 4pence, when I moved from them I had over paid £19.86 for the same period in 2017 wrote to them and no reply just another bill. I have a collection of email's automated responses and no email reply's over the unfortunate time I was with them. Avoid them!!”

“They billed us for water when we hadn’t opened an account with them ( business). They were quite aggressive asking for payment. I tried to change suppliers and they blocked the change until I had payed them monies I wasn’t even sure we owed. A year plus later they billed us more with no explanation. I wrote to them / phoned them to say I didn’t owe them money. No response to the letter and the rep on the phone couldn’t help me because there was no account number on the letter. They then started threatening legal action (miraculously an account number started appearing on the letters) I paid them money I don’t owe to get rid of them once and for all. Awful, awful company”

“Had my account taken over by them in July 2018. received one bill for advanced charges which was paid promptly. An invoice with an incorrect reading was never sent in March 19 and that reading was used as the basis for an estimated reading for the March 20 bill. This resulted in an voice for approximately 3 times what it should be. castle water are intransigent on the 'phone, take 10 days (if you are lucky) to respond to emails but are quick to tell you what they can't do and seem unable to tell you what they can. I have now reported them to Ofwat. Avoid this company at all costs, quite possibly the most incompetent and unhelpful business I have ever had the misfortune to deal with.”

“Kaffkaesque company, it seems. Have just spent 40+ minutes unanswered on the phone to their customer service on a Tuesday afternoon. I wanted to clarify 2 conflicting bills, one of which I understood I'd paid by direct debit already. Confirmed my impression of a company that is hopelessly understaffed - and so many people out of work. P.D.Walsh”

“Appalling customer service and infuriating and infathomable billing system. Calls are never returned, systems not updated. It’s mind boggling how this company is still operating.”

“Very poor response from customer support, billed me for a meter which doesnt exist and when questioned was told the meter has in fact been removed - but by whom! They just pass the buck back and forth between Thames water and themselves.”
