SSE Water Ltd (SSEW) is an appointed water & sewerage undertaker operating in the New Appointments and Variations (NAV) market.

In November 2017 the water industry regulator, Ofwat, issued ’Code for adoption agreements’ setting out expectations for how the water industry will develop and maintain procedures and processes for the adoption of assets. Under the terms of the Code, model adoption agreements and sector guidance are to be developed by the industry for both water and sewerage assets. While these are being developed, transitional arrangements apply and, as part of these, water and sewerage companies are required to set out specified information on adoption for interested parties. This document fulfils SSEW’s obligations in this regard. More information may be found at:

Delivery Options

Customers of water companies may choose to deliver their new networks and connections in a variety of ways, as outlined below.


A developer may choose to employ a ‘Self-Lay Provider’ (SLP) to lay new water and/or sewerage networks and associated connections on their development site. The SLP must be recognised by the industry and be able to demonstrate that it is capable of delivering networks to a suitable standard. Developers wishing to use this method within any of SSEW’s appointed areas must contact us at We'll respond within two business days. Further information on the general standards relating to Self-Lay may be found at


The Water Industry Act 1991 (Sections 41 for water and 106 for sewerage) sets out the duties of water and sewerage undertakers with respect to the provision of new networks. If you wish to requisition all or part of your new networks, please contact us at We'll respond within two business days.

New Appointee

A New Appointee is an undertaker appointed by Ofwat and operating within the New Appointments and Variations (NAV) market. Developers or other authorised persons may elect to engage with a NAV company and agree methods of delivery for the new networks. The NAV company will be required to obtain a variation to its appointment to permit it to deliver water and/or sewerage services to customers within a specified area.

Information on the NAV process may be found at

Current Level of Activity

SSEW is a New Appointee and provides the majority of the required infrastructure in its appointed areas by this route. As such, requisition, self-lay and NAV provisions haven't been significant methods of asset delivery within SSEW’s appointed areas. These options are supported on a case by case basis and there is no reporting against service levels. Please contact John Gibson at if you wish to discuss any of these routes for the provision of water or sewerage infrastructure.
