Applying to self-lay

Developers can choose to use a self-lay provider (SLP) to install or ‘self-lay’ new water mains and/or service connections.
If you are exploring the opportunity of using a SLP to deliver your water requirements then please take a look at the Code of Practice which has been developed in conjunction with water companies, SLPs and Water UK. This document sets out the expectations of both parties and importantly agrees the timescales at each milestone of a laying a water main or services.
If you are a self-lay provider then take a look at the Dee Valley self-lay provider policy and guidance sheet link below. This provides information on any network specific information you need, along with our contact details.

The policy describes the processes and procedures that need to be followed and sets out the terms on which Dee Valley Water will enter into an agreement with a developer for the self laying of mains and services pipes.
