Scottish Water

Scottish Water provides water and waste water services to households across Scotland and runs Scotland’s network of pipes, water sources and treatment works.
It also acts as the wholesaler of water and waste water services in the competitive market for business customers in Scotland.

Licensed suppliers

Since 1 April 2008 business customers have been able to choose their water and waste water service supplier. New suppliers in the Scottish water industry must be licensed by us.  You can find out more about your choice of supplier and how to switch at our dedicated business customer website,


The Central Market Agency (CMA) administers the competitive market. It maintains the register of who supplies each business customer in Scotland. The CMA also calculates the money owed by each supplier to Scottish Water for wholesale services.
