Self laying new mains and services

We understand that developers want all utilities, including water, installed quickly and economically. Our Developer Services team are fully set up to assist developers who wish to use a self lay organisation (SLO), and we often make an asset payment when we adopt a self laid main. We have arrangements with Lloyds Register ( that allow developers to safely choose an SLO that fully understands our policies and procedures for both new mains and service connections.

Our self lay policy details how we manage self lay and provide SLO’s information on relevant policies and procedures.

Before the work starts, we will enter into a self lay agreement with you and your SLO so that we are all clear what work is being done and when your new water supplies will be needed.
