We’re here to help. Understanding your bill shouldn’t be a puzzle — so we’ve made it easy to break down the charges and see exactly what you’re paying for.
Your business water and wastewater bill is mostly made up of wholesale charges, which are set by your local Wholesaler and approved by the industry regulator, Ofwat. These charges make up around 90% of your total bill, and you’ll pay the same wholesale rates no matter who your water retailer is.
At Castle Water, we’re committed to fair, transparent pricing — and to helping you make sense of your charges. Use our simple tool below to explore each section of your bill.
