As part of an ongoing process to introduce competition in to the water services market, we operate the Water Industry Registration Scheme (WIRS) on behalf of water utility companies.

The Water Industry Registration Scheme - Accredited Entity (WIRSAE) has been developed to allow companies, who fulfil the scheme requirements, to become registered as accredited WIRSAE Providers. WIRSAE Providers are referred to as Accredited Entities in the Wholesale Retail Code.
