“If you can avoid Castle Water do so, Unhelpful, non-responsive, quick to appoint bailiffs for incorrectly addressed bills (nothing to do with us) wont change meter or read meter - even when I was able to provide a reading they would not credit the over estimated bill..... and so on. Shouldn't be allowed to trade I agree with every other comment below.”

“Castle water is a morally bankrupt company with no ethics whatsoever - so I read with interest that the ceo John Reynolds has written books on business ethics - they have put my business and staff at risk by totally immoral business practices, including totally ignoring requests for meter reads, checks and just read and ignore emails.. it hs taken months to get to nowhere but an increasing bill and no water.. if you find you are with castle when you move in to a premises move immediately”

“The worst company I have to deal with in my business, they took over from affinity water and my bills doubled ,they charged me for water when my business was closed for 33weeks due to covid lock down ,I wasn't using any water idiots . Was told it would get sorted but then there dept recovering company sent me threatening letters . Recently my bill increased by £250 over a weekend after being told once again that there would be no more charges whilst they investigate the complaint and the bill would be put on hold till January, then surprise surprise another letter today to pay the bill. About time this sxxt show of a company gets investigated, MINUS 10☆ would be my real rating if I could.”

“As per the comments below; they are trying to charge me for a bill which doesn't relate to me. I purchased the property on 3 Sept 2021 and they want me to pay a bill from 1 Jan 2021 - Aug 2021!?!? Sent emails to CEO, customer service etc... None have been responded to. They keep sending threatening letters etc... Anyway, i will ignore all from now. They can take me to court if they like! Had similar problems with them in 2017. Took 4 years to resolve. The most retarded company i have ever dealt with. I cannot believe a firm like this is allowed to operate something as important as mains water in the UK. CEO needs to be executed!!!”

“The most disgusting company I have ever had the misfortune encounter within my whole career. Take a look at their Company accounts and decide for yourselves the level of corrupt negotiations they force upon their clientele. If Castle Water was a ‘intimate relationship’ my advice would be to run, run, run as fast as you can!”

“Finally, after two years of challenging their charges, and fighting off their debt collectors/solicitors, we got our bill corrected from nearly £17,000 to just £5,000. All I can say is, check your bills very very carefully as they clearly do not have any reliable internal procedures to prevent over-charging and they refused to accept our meter readings even when backed up with photographic evidence.”

“We were incorrectly placed with Castle Water (we're domestic not business). They currently hold over £4,000.00 of my money that they keep telling me they will refund me as my account is in credit. Months have passed with numerous phone calls and still no refund. I starting to think they are going bust!!”

“These guys are chasing us for a debt that isn't ours!! These guys are chasing us for a debt, not in our name for a service we have never used. Never ever dealt with these guys. They are simply trying it on with similarly named individuals. They have passed on debt to the collection agency. All I can say at this point is these guys are the worst!”

“Appalling customer service over a considerable period, Nobody knows what they are doing and it is virtually impossible to contact anyone. Our invoices have been far higher than they should be”

“I had the misfortune to have inherited Castle Water as my new water provider. I am appalled at the nasty, threatening letters that they send out which have no basis in fact and decided to change companies. I am now with Everflow but unfortunately because of Castle Water's policy of billing in advance I have a large credit on one account and a small debit on another farm account. Of course they have ignored the large credit owed to me but I have just had one of their nasty letters threatening me with debt collectors. Don't know what to do. It almost makes one lose the will to live.”

“They keep sending bills for property I don’t own. They owe me for payments for water to these properties, £800-£1000 approximately but they don’t check it out. After two official complaints and days writing, emailing and phoning they say it’s sorted, no money yet and they’ve said that before. Until the next time. Now they want me to travel to a property I don’t live in to read the meter. Unbelievable!”

“Completely incompetent and disorganised I never registered with them and switched to another water provider after deregulation as I have had lots of negetive feedback . My only hope now is that they are investigated by Ofwat and are fined for there scrupulous handling of customers. Forget trying to contact them by phone as the option menu keeps on repeating itself and no one answers the phone. You have been warned AVOID AVIOD AVOID.”

“to be told you are levying a late payment charge "because I paid my bills during covid" is probably the most ridiculous excuse for extortion that I've heard in more than 30 years in business this is my review onTrust Pilot which explains why I am demanding an apology and removal of your penalty charges https://www.trustpilot.com/submitted/review?correlationid=ffd08deb-b37a-4097-9b36-674b8996e982”

“Worst company avoid them at all costs . Dishonest they cheat and lie my bills seem to be going up even though my consumption has decreased. I have been trying to sort my bills with them since 2020 . They don’t care they ignore you and keep telling you to pay your bill without even trying to deal with the issues . If you value your time and you do not want mental health problems or anxiety please please avoid castle water . They will give you so much stress it will make you ill . That’s what they have been doing to me for the past 2 years .”

“This is one of the worse case of management there is. Huge amount of resources are put into inefficient debt collection while they have a direct debt in place!.....I hade some 30 pieces of mail for exactly this. Want to call them? Be ready for around 30 minutes of wait. Want to give a meter reading online? This must be the most unintelligent form there is. Wants you to fill in several items from address to account number (which they manage to change from time to time!) Supply source number which they do not specify which of the two & onwards to meter number and a ready finally a PHOTO of the same ....this is like we do the filing & details online for that non-existent administration. This company needs more intelligent managers to give ease of communication & customer satisfaction....currently it is a barrier to life!”

“Where do I start!!!!!!! The worst company I have ever encountered. Never even signed up with them and don't pay for waste water as all done through landlords septic tank. They have threatened all sorts of legal action and cutting off our water supply - THEY DON'T SUPPLY OUR WATER!!!!!!!! Complete shower of S****. Have now passed us on to a debt collection agency - can't wait to speak to them!! Four years of this and I am fed up to the back teeth of them. How come they haven't been shut down by the ombudsman? How do they get away with harassing customers in this way. Be warned and if you get a call from them trying to sign you up (though they seem to just skim over that bit) run a mile!!!!”
