What we do

We are a membership organisation set up in April 2014 for companies or group companies who are responsible for preparing responses to the CON29DW Residential or the CON29DW Commercial searches that DWSN has developed in collaboration with the Law Society. DWSN is structured as a not-for-profit company limited by guarantee.

DWSN sets out clear Standards that ensure DWSN members maintain high standards of product quality, consumer protection and customer service in the supply of responses to both CON29DW reports.

We promote the benefits of both the CON29DW Residential and Commercial searches. Both searches are created using complex and current data which is then analysed by knowledgeable teams during the preparation process.

DWSN works with stakeholders to ensure robust standardised products that are developed specifically for either the commercial or residential markets.

DWSN provides technical support to members and other industry bodies, such as the Law Society and Water UK, regarding issues in this specialist area.

DWSN’s YouTube channel provides access to online content to help develop a better understanding of the CON29DW searches and the areas that they cover, providing ongoing CPD support for conveyancing professionals.
