Ofwat is beginning a consultation today into plans by Independent Water Networks Limited (IWNL) to provide water and sewerage services to a second new development in Northamptonshire.

The regulator is proposing to grant an inset appointment to IWNL, which will allow it to supply services to a major development of nearly 5,100 homes and 51 business units at Priors Hall, in Corby. As the development is in Anglian Water's area of supply, Ofwat is now seeking views on its proposal to allow a change of supplier for the site.

If it gets the go-ahead, customers at the site will benefit – IWNL is proposing to charge its customers 5% less per cubic metre of water supplied than Anglian Water would charge. All other charges will be the same as Anglian Water's.

IWNL has committed that its customers will pay no more than they would have done had they been supplied by Anglian Water. IWNL will also be subject to the same level of customer service requirements as other water and sewerage companies.

Earlier this month, Ofwat granted IWNL its first inset appointment for a housing development also in Corby. If successful, this proposal would see IWNL's area of appointment changed to include the Priors Hall site.
