Water Industry Registration Scheme (WIRS) & WIRSAE.

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

About WIRS

The Water Industry Registration Scheme is for contractors who provide new connections to the existing water supply or sewerage system. These are referred to as "self-lay" organisations or SLOs.

In order to be WIRS accredited, the companies undergo technical assessments from LRQA. We assess several areas, including design, construction, connections, commissioning and project management.  By becoming WIRS accredited, companies don't need to be approved by 22 separate water companies.


The Water Industry Registration Scheme - Accredited Entity has been developed to allow contractors, 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.

WIRSAE accreditation (and subsequent registration), allows WIRSAE Providers to tender for and to carry out for Retailers' water supply disconnections and meter installation/replacement works, relevant to their level of accreditation, as an alternative to the Wholesaler, known as the adopting utility, in whose area the work is being done.
