Our charging arrangements

We collect and dispose of wastewater across the southeast of England and supply water in parts of this region.

Other water supply companies supply water to the rest of our region. Please contact them if you have any queries about their charges.

The information below is for when you intend to connect premises to the public water supply or a public sewer. This applies even if you're using an existing drainage connection. It explains the liability to pay infrastructure charges to Southern Water and the cost of making the connection.
