“Similar experience to other reviewers. Castle Water are trying to say we are a customer of theirs and we aren't. Never have been never will but we are getting letters demanding overdue payment. Written twice and spoken to customer services but they don't listen. They can whistle for the money and take me to court where I'll have my day with them.”

“Difficult to know where to start with our dreadful experience of dealing with this company (specifically billing and complaints). Never, in my 36 years of running our business, have I come across such ineptitude and intransigence - it is like trying to communicate and reason with malfunctioning robots. After a year of stress, we have finally decided to cut our losses, close our account and go elsewhere. Avoid this company like the plague!”

“How can this company continue trading I have never in my life experienced such ruthless people, final demands late penalty charges, threats of dept collectors bill after bill more bills , I sent dozens of emails explaining I didn’t owe this amount of money , phoned then numerous times taking up to 30mins to talk to someone each time someone different each time promising to sort my bill out , guess what nothing happened, eventually after many sleepless night I paid them , and now they have admitted they I’ve been over charged why has this taken nearly 4months to sort out , my advice take your business elsewhere they don’t deserve it !! I have given them seven days to refund my money watch this space might be my turn to issue them £75 late payment charge”

“They charged me over £1700 for my water bill, found out had a internal leak. Applied for leak allowance but was rejected as it was internal! Now they have sent so many threatening letters and added charges taking the cost to £1900. The people on the call centre were very rude and unhelpful. One of the worse companies to deal with and do not wiish anyone to have to deal with such a unprofessional establishment. I also do not understand why you would get companies to pay for water they havent even used yet by charging 6 months in advance. Just a way to make more money for yourselves without the concern of the effects on SMEs. SHAMEFUL”

“They sent random 2200£ bill for 6 month. Sent them pics of meter but won’t listen and recovery team sending threatening letters. They bully, and are truly non sense people. Anyone out in uk authorities, help small businesses. I am contacting a solicitor to stop them bullying me.”

“Truly awful. 3 times I've had to call back to get them to do the same basic thing. Each time they confirmed they'd done it, each time I called back a couple of weeks later and they had no record of it having been done. Is this even a real company or some kind of complex scam? Atrocious”

“The mafia in disguise. They called me two years after I had left the premises and closed the company, to claim money from me for a premises which had the water bill included, owned and run by Workspace Group. They had previously also tried to bill me for an occupant who had hired the space in the years before I moved in. This is a company trying to look "respectable" but who behave with the mentality of the mafia. Their main occupation is bullying people for money, under the guise of water services.”

“These clowns couldn't run the proverbial drinks do in a brewery let alone a water company. No bills, threatening letters due to non-payment of non-bills, daily interest on the previous and then legal threats for 88p accued interest. COWBOYS. Avoid.”

“Honestly Rubish service rip of no one person I spoke to seem to know what to do . They charge me back for few years and I was not even a customer with them they took the account without my permission I don’t even agree contract with them and they want to charge unbelievable number. If I have a water park I will not have this bill . Can’t describe enough how bad this castle water . They should change the name to the Rubish service water”

“Dreadful company. Mismanaged my account. Overcharged. Sent threatening letters. Never dealt with my formal complaint. Blamed Thames Water for everything. Avoid if possible.”

“Awful company. Keep overcharging me. No scruples. Rude and unhelpful. Daylight robbery. The worst company I have ever had the misfortune to do business with. They should be shamed of themselves. Overcharging all the time. They need to be investigated.”

“I posted a review on Trustpilot, but then realised that the 4.6 star average rating for a water company looked wildly out of place. I reviewed a few of the comments and there are a remarkable number of single review 5 star comments (with no business names) and one that has several 10s which are just copy pasted every month. This site looks more like my experience. Avoid if possible.”

“Very poor Company to Customers & Staff. CEO on a power trip how he has ever written books on ethics is beyond a joke. Do yourself a favour and go to another company like Business Stream.”

“The company is totally confused with their affair and running the business and all they care about is to charge their customers and they have no courtesy whatsoever.”
