Accredited entities

Southern Water recognises the Water Industry Accredited Entity Scheme (WIRSAE) to allow retailers operating in our area the opportunity to undertake temporary disconnection/reconnection and meter exchange activities in line with the market codes and the requirements of the scheme.

To carry out these activities, retailers or their nominated service providers will need to be certified as an accredited entity. The Southern Water scheme will be administered by Lloyd's Register, which will carry out the initial accreditation assessments, certification and on-going monitoring on behalf of Southern Water.

Details of the accredited entity scheme and how to apply for accreditation are available on the Lloyd's Register website. You will find a dedicated section entitled WIRSAE.

Accredited entities will need to comply with Southern Water’s addendum to the Generic Code of Practice and, in addition, an agreement will need to be signed with Southern Water. Details of our addendum and agreement are available below.

Should you have any queries, including how to sign an agreement with Southern Water, please get in touch at [email protected].
