Infrastructure Charges

Our Infrastructure Charges are currently set at £375.00.

You have to pay infrastructure charges on top of the cost of connecting a property to the water main and/or wastewater system (provided by Anglian Water or Thames Water depending on your location within our area). Each company can raise infrastructure charges for connecting premises for household purposes to a public water main or to a public sewer for the first time. Ofwat set an upper limit on this charge and this increases each year in line with inflation.


See below for details of our charges for new connections:
