We never signed up to Castle Water, but first our water supply moved to them, followed by our sewerage. Since they took over the sewerage the pricing has more than DOUBLED in three years. I have complained bout being charged for "metered foul sewerage metering" - which implies i'm being charged for my sewerage being metered. I have now demanded a photograph of the meter and a reading from within the last 12 months, otherwise i'm deducting it from the bill ! I have also had an ongoing battle with their credit terms of 14 days, which i never accepted. We pay all of our bills on 30 days (like most other companies) and every time they invoice us they write a threatening letter about cutting us off because we are late paying. I would leave them in an instant but there isn't long left on our lease and we may not be in the premises long enough to get a new contract with anyone decent.
