Self Lay

Banner image

As an alternative to having new mains and service connections installed by us, developers can arrange for the work to be carried out by qualified contractors.

A National Code of Practice is now available. This Code of Practice is for when a Developer appoints an independent Self-Lay Provider (known as SLP) to undertake the contestable work of designing and/or installing water mains and services on a new development site. It details processes, requirements for the work and specifies the role of SLP's and Water Companies. Additionally you can find guidance from Ofwat on Self Lay here.

The work must be carried out by a company that is accredited with the Water Industry Registration Scheme (WIRS) which is administered by Lloyds Register.

Developers may wish to request that we carry out a Pre Development Capacity Enquiry for proposed developments to ensure there is adequate capacity within the clean water network.

As an alternative to having new mains and service connections installed by a Self Lay Organisation, developers can arrange for the work to be carried out by us.
