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 should be read in conjunction with our specific Policy and Addendum.  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.
