As an SES Business Water customer, you’ve always benefitted from one combined bill covering your water and waste water services, and one point of contact when you need advice or assistance.

However, this is set to change. England’s water marketplace will open on 1st April 2017, meaning that all water companies will need to apply for retail licences if they are to manage customer accounts. Thames Water - your ‘behind the scenes’ wastewater service provider – has decided that they do not wish to become a retailer next year and has sold your wastewater account to Castle Water. All Thames Water wastewater customers will be migrated over to Castle Water’s billing systems, meaning you will start to receive two separate bills: one from us for your water supply, and one from Castle Water for your wastewater services.

We understand that for many businesses this might not be welcome news, which is why we’d like to help you understand the changes taking place and explain how you can navigate your business towards a better deal on your water services.

On this page, you’ll find information on exactly what is happening, answers to the most frequently asked questions, and advice on what you can do to simplify management of your water account; including how you can make the choice to continue receiving one consolidated bill for all your water services.

Claim your reward! Keep your wastewater account with SES Business Water and receive a credit on your next combined bill after April.
