IB 05/12 Ofwat varies the appointment of water and sewerage services supplier at Marine Wharf, Deptford


Ofwat has varied the appointment of SSE Water to enable it to supply water and sewerage services to a site in Deptford called Marine Wharf. The reasons for our decision are set out in our decision document.

New appointments and variations include one company replacing another as the appointee for a specific geographic area. SSE Water will replace Thames Water as the statutory water and sewerage services supplier for Marine Wharf.

SSE Water will supply water and sewerage services to a development of 532 household properties. SSE Water will serve its customers by taking a bulk supply of water from Thames Water and it will make a bulk connection to Thames Water’s sewers.

SSE Water will charge its customers at Marine Wharf based on the existing Thames Water household metered tariffs for water and sewerage.

SSE Water was granted its appointment as a water and sewerage company in October 2007 for a housing development called Old Sarum, near Salisbury in Wessex Water’s area. It has since been granted a further fifteen variations to its appointment at a variety of sites in different company’s areas throughout England and Wales.


Notes to Editors:


  1. Ofwat (The Water Services Regulation Authority) is the economic regulator of water and sewerage companies in England and Wales. It exercises its powers in a way that it judges will protect the interests of consumers, promote value and safeguard future water and sewerage services by allowing efficient companies to carry out their functions properly, and finance them.
  2. New appointments and variations are the route by which one company replaces another as the appointed water and/or sewerage company for a specified area. The replacement water and sewerage company will have all of the same duties and responsibilities as the previous statutory water and sewerage company for the specified area.
  3. There are three qualifying criteria for seeking a new appointment or variation:
    • an area does not contain any premises that receive services from an appointed water or sewerage company (it is ‘unserved’);
    • a customer uses (or is likely to use) at least 50 million litres of water a year (in England) or 250 million litres of water a year (in Wales) at each of its premises and wants to change its supplier (a ‘large user’); or
    • the existing appointed company agrees to transfer part of its area to a different company (a transfer by ‘consent’).
