As a developer you have 3 choices on how the Water mains and Services are installed on your Development site.

• You can ask Wessex Water to install the Water mains & Services 
• You can use an Accredited Self lay provider (SLP) to install the Water mains & Services 
• New Appointments and Variations (NAVs) - details about NAVs and how to apply

If you are choosing to lay water mains yourself by using an accredited self lay provider (SLP). A list of WIRS accredited SLPs can be found on the Lloyds Register. You can also familiarise yourself with the process by reading through the Water Sector Guidance (WSG).
