Customer Notice

Our offices and phone lines will be closed on Monday 27 May for the Bank Holiday. We will reopen on Tuesday 28 May at 8am. You can still make a payment online. If you experience an emergency or unplanned disruption to your water supply and/or wastewater service whilst we are closed, please call your Water Network Owner. You can find a list of emergency numbers here. If you experience a problem with the water pipework inside your own building/site, you should call your plumber in the first instance.

Still paying separately for your business water and waste? You could be flushing your time and money down the drain. With Castle Water, combine water and waste to receive one simple bill – and save money in the process.

We can provide one simple bill for all consumption and charges, for all your meters, in one invoice including:

  • Water
  • Wastewater
  • Trade Effluent
  • Drainage

Large and multi-site customers

If you have multiple business premises, we can also make life simpler with one consolidated bill and one set of payment terms for all sites.

This service is ideal for large, multi-meter and multi-site customers who wish to receive a single invoiced amount for all their water and wastewater charges, requiring just one single monthly payment.

Consolidated billing also makes it easy to manage your costs. It is easier to view and compare water usage over time and across different sites, helping you to identify irregular consumption levels and potential opportunities to improve water efficiency.

To find out more about consolidated billing, or to merge your water and sewerage accounts to Castle Water, please contact us at switch@castlewater.co.uk – or chat with an adviser online now.
