Building multiple properties or large developments

Our expert Developer Services team are on hand to offer impartial advice and guidance on the specific water supply and sewerage needs for your development.

Understanding your options

In most cases you can choose to: 

  • have an approved self-lay contractor (supply) or a suitably qualified contractor (waste) undertake the work
  • ask a NAV (New Appointment & Variation) to serve your development in a defined area known as an ‘inset’ 
  • ask us to provide a cost estimate to carry out the work for you 

Each of these options has its own benefits, and third party providers may be able to offer a more cost effective and flexible service. The choice is entirely yours to make.

Did you know?

You can use our charging calculator to work out an ‘up-front’ cost for us to service your site, which you can compare against alternative service providers.

No matter how you choose to deliver supply and waste water services to your site, we always recommend that you start by submitting a pre-development enquiry to obtain advice and support regarding the location and capacity of our existing infrastructure.
