The Water Industry Registration Scheme (WIRS)

The Water Industry Registration Scheme (WIRS) has been developed to allow contractors to carry out installation and commissioning of water mains and services to be adopted by the Water Utilities (WU). Any Self Lay Organisation (SLO) contracted to carry out contestable work (as defined by OFWAT and detailed in the National Self-Lay Code of Practice) can be accredited under this scheme.
