“This company is a con.!! They haven't got a clue. Just robbing small businesses. I had a bill in late June of £900 for the year. ( depth collection). Which resulted in the total bill being just under £2000. I have just received a 3 month bill for £600. No one wants to talk or explain. Scam company.!!!!”

“Coercive, unethical and threatening - Company has overcharged us and is refusing to refund. We are now in month 4 of Castle Water 'escalating' the issue, but never resolving it. In the meantime they are chasing £19 of unpaid bills & are threatening 'further action'. This is a company that deliberately has set out its customer service processes in order to coerce and never act.”

“Castle Water has been severely overcharging my small family business. They are charging my business over £2700 for just one month!!! The average competitive water bill in the area my business is situated is approximately £250 PER YEAR. That is 980% MORE compared to the accurate competitive water rates charged by other providers! SAVE YOURSELF tens of thousands of pounds for your business and homes by just NOT associating with Castle Water EVER. There are countless other cheaper alternative water providers which can be found with just a simple google search. (Thank me later).”

“An appalling company with no interest in customer service. The latest they have sent me a fine for preventing or restricting access to my water meter. It is out on the roadside, I doubt that Castle Water have ever sent anyone to try and read it, and certainly have not contacted me about it. The sooner I switch to another supplier the better. I wish more people realised that they are able to switch to and don’t have to be stuck with Castle Water.”

“Thanks to castle water I’m having to close my company after 12 years as they’re billing me £10,000 for 3 years of water. I’m a small company on our knees already and they want this. It’s criminal.”

“How can this company operate so unlawfully? OFWAT need to address this company fast as they are profiteering illegally at the customers expense. Nobody has anything positive to say about them and most Trust Pilot reviews are insiders.”

“They changed my water supply from Thames water to castle water without noticing me. I was a student at that time, but they set me in a business account, charge me 300pound a month. When I send them all the documents that prove I do not own a business at that property, and do not live at the place anymore. They just ignored my email, and keep sending me bills. They are purely bullys.”

“I agree with every review, they are not even worth a one star , we have a little family garage business on a small trading estate, out of the other 10 businesses on the estate no one has received a water bill , we have an outside porta loo , and an outside tap we use to fill the kettle and wash our hands , and today received a bill for £10259.00 !”

“CASTLE WATER IS THE MOST CROCK company in the UK Terrible service ,no respect,, waste your time, and do whatever it takes to add unnecessary charges on your bill such as DEBIT RECOVERY CHARGES £329 AND LATE PATMENT CHARGES £55 for what ?????? Speaking to customer services is pointless, and next call they deny that they already spoke with you before, they give you false information to get you to pay recovery charges. Huge mistake switching to their company £1800 is my bill which is 85% overcharges for a small retail shop that has a toilet only.””

“Failed to read meter for years, then attempted to charge for taking a meter reading before realising that a reading had actually been taken. Interest and debt collection charges are certainly a good way of losing customers in a competitive market: I'll be sure to close the account in the coming month. Their website states "The Best Water Suppliers [sic] for Business Owners" - no source provided, and no means of proving this outrageous claim. Unethical. Avoid at all costs.”

“I have been reading all the reviews below and it sums up what I am currently experiencing with them. I would like to complain formally to cow council and wondered if any of you that have complaint would like to join me? I think if we join efforts and tell our stories that seem to be inline to what I've experienced, we can get faster resolutions. If you have an interest, please put a like and we can all get in touch. Many thanks,”

“Ok so we have experienced harassment and intimidation from Castle Water . It would seem they believe they are above Laws in England , Has anyone received support from Trading standards or the Police to investigate this company for trying to Obtain monies without receiving services”

“Castle water did not read the meter for 2 years, even after being asked to. After months of not being able to locate it, even though they told me where to find it a read it myself. Sent a bill to me for clearing it even though not on my land, and it had already been cleared and photos sent to them. They did not even do any work clearing, I disputed the charge and put account on hold, then charged me for not paying the bill. They are a fraudulent company!.”

“I’ve been tangled in unjust water charges that I have received from Castle Water for the past two years. Despite repeated explanations provided to Castle Water, the issue of overcharging for water usage on my property has not been resolved. I have clearly stated that my property is stripped back and has no water usage, as there are no pipes on the premises. My property has been disconnected from the mains water since 2021. Castle Water has carried on charging me for water that I am not using, as I share my water supply with neighbouring properties. I have made numerous attempts to rectify this issue by providing evidence of the lack of water usage on my property but to no avail. It is unacceptable for Castle Water to continue charging me for services I do not benefit from. I have repeatedly requested that Castle Water thoroughly investigate this issue and adjust my billing accordingly. I am afraid in 2 years, Castle Water has not taken any of my emails, complaints or phone calls seriously. Castle water’s tactic is continued disregard of facts & wearing the person out so that one gives up & pays.”

“They continue to issue a bill, don't inform me that they have issued it and then pursue me for late payment (even after I have paid}!Ive blocked the automatic voice calls because they are so stressful. It is tantamount to harrassment! i cancelled my DD to them because I just dont trust them. They have so many departments and seem very inefficent but it is always the customer that foots the bill! I stopped them sending me paper bills because they either didnt arrive at all or they would arrive at same time as the threatening, bullying letters. Soul less company operating in the rarified atmosphere of what should be a public utility.”

“Castle Water change bills from 6 monthly to monthly without your permission. They then send bills with penalties even after you have paid for your water. So a £26 bill escalates to several hundred pounds and the scam continues. In our area Castle Water has bullied many customers,including people with poor English,cutting them off. Utilitity companies inform you of a change in contract etc and give you a choice but NOT Castle Water. We never agreed to use Castle Water and it won’t allow you to move to another company whilst their fictitious penalties are in place. The Water Council seem to have a long backlog of complaints against Castle Water so don’t bring them to task!”
