IB 11/10: Ofwat varies the appointment of water and sewerage supplier at Berryfields in Aylesbury


Ofwat has varied the appointment of Independent Water Networks Limited (IWN) to enable it to provide water and sewerage services to a site in Aylesbury called Berryfields. The reasons for our decision are set out in our decision document.

IWN will supply water and sewerage services to a development of 3,600 household properties.

IWN proposes to offer customers at Berryfields a 5% discount on the volumetric water charges of Thames Water.

New appointments and variations include one company replacing another as the statutory supplier for a specific geographic area. IWN will provide water and sewerage services to customers at Berryfields via bulk connections to Thames Water’s network.

IWN was granted its new appointment in October 2007 for a housing development at Long Croft Road near Corby, and it has been granted further variations to this appointment at Priors Hall in Corby, Great Billing Way in Northampton, Brooklands in Milton Keynes, The Bridge in Dartford and King’s Cross Central in London.
