One Bill

Many customers have told us of their frustration with getting a bill from South East Water for their household drinking water, and another one from Southern Water for their wastewater services.

So we’re really pleased to be teaming up with Southern Water to launch “One Bill” - a single bill from South East Water that will also include Southern Water’s charges too.

Designed to make things simpler for our shared customers, One Bill will mean in future you will only need to contact one company - South East Water - to make payments for both of the services you receive!

We’re aiming to give customers a ‘five out of five’ service in everything we do and hope you really like your new One Bill.
