I had to contact Castle Water today as

I had to contact Castle Water today as, unfortunately, we have fallen three months behind with our payments. The outstanding balance was paid yesterday, 30 June 2026, however, we missed the deadline by one day. As a company, we do not currently have the facilities to make immediate payments.
I spoke to Robert this afternoon and asked whether the late payment charges, which were only applied today, could be removed. Robert was very understanding and is reviewing the request.

Tracey Arthur was polite

Tracey Arthur was polite, knowledgeable, and helpful in responding to my questions. On a couple of occasions, she needed to place me on hold, but I prefer that to being given incorrect information. The issue is still not resolved, but I now have the information I need to take it forward.

I had a very professional experience with Castle Water

I had a very professional experience with Castle Water. I had an issue with a bill which I was unable to resolve. I was then referred to Jack Dickson, who made the whole experience smooth and transparent, I received regular updates and finally got a satisfied conclusion. I cannot recommend Jack enough, who took the responsibility upon himself to ensure the issue was resolved in a professional and orderly manner with regular updates. Communication was second to none both on the phone and via the portal(email). Thank you to Jack and Castle Water.

Check their Google Reviews, it says it all...

Avoid this company!!!!!!!!
Trigger happy to disconnect water without the opportunity to put a payment plan in place.
Then charge a £960 disconnection fee & a further £450 to reconnect.
How cruel, in this heatwave.
Even though we did not receive the original bills.
Rude, unhelpful, condescending & unwilling to help

A utility Company should not act so rash, neither have the power to be so aggressive in particular as a water supplier.

Engage is just as useless. Payment in full or it's a waste of time talking to them.
