New infrastructure

Connecting water supplies to a new development will require new water mains in most cases.

A new water main extension is necessary for any development where the existing road network is being extended, irrespective of whether the new road will be adopted by the local highways authority. If the development you have applied for requires a new water mains extension then please make payment of £168.43 + VAT to cover the cost of the design. We cannot progress with producing quotations until we are in receipt of this payment.

We offer a full design and installation service.  Alternatively, you can arrange for the mains to be installed by an approved self-lay organisation.  The following will provide you with all the information you need on how we handle new mains enquiries.

The regulator Ofwat provides more information on the requisition and self-lay processes on its website at
