Details
This is a list of water companies that have been granted permission to withdraw from the non-household retail market (known as “retail exit”). These companies stopped providing retail services to their non-household customers when the market opened in April 2017.
The water companies will transfer their non-household customers to an alternative supplier (known as an “acquiring licensee”). The alternative supplier will then be responsible for providing the retail services to those customers.
