About the Scottish Water Industry


In March 2005 the Scottish Government passed legislation allowing for competition in the water industry in Scotland. On 1st April 2008 the new competitive arrangements came into effect. For the first time ever, business customers can now choose their water supplier. Scottish Water continues to deliver water and remove wastewater, but competing supply companies carry out retail activities, such as meter reading, billing and customer support.

The supply companies bill their individual customers; Scottish Water bills the supply companies.

There has been no change to the current arrangements for domestic customers.

About the Central Market Agency

The Central Market Agency Ltd (CMA) is the organisation that administers the Market for water and wastewater retail services in Scotland. The CMA is at the hub of the new competitive arrangements, operating the computer systems that run the Market. The CMA keeps a record of supplier activities in the market, including recording which suppliers are responsible for the services at each connection point. Every month the CMA uses this information to work out the wholesale charges that suppliers must pay to Scottish Water.

The CMA is a company limited by guarantee and owned by its members. The current members of the CMA are: Scottish Water, Business Stream, Anglian Water Business, Wessex Water Ltd, Aimera, Severn Trent Select Ltd, United Utilities,Thames Water Commercial Services, Veolia Water Projects, Clear Business Water Ltd, Cobalt Water Ltd, Kelda Water Services (Retail) Ltd, Real Water (Edinburgh) Ltd, Commercial Water Solutions Ltd, Castle Water Ltd, Blue Business Water Ltd, NWG Business Limited, Source for Business Ltd,  Everflow Ltd, Sutton and East Surrey Water Services Limited, Pure (CGV) Limited Regent Water Limited,  Brightwater Services Ltd and Regent Water Limited. As new supply companies enter the Market they will become members of the CMA. The chairman of the CMA is Dr. Brian Saunders.

The rules governing all Market Participants are set out in a Market Code and an Operational Code; these may be found on other pages of this website. The industry meets every two months as a “Technical Panel”, under the Chairmanship of the CMA, and is responsible for the ongoing development of these documents.
