We are an independent non-ministerial government department set up to ensure the effective regulation of the Electricity, Gas and Water and Sewerage industries in Northern Ireland.

Scheme of charges

We are required under the Water and Sewerage Services (NI) Order to approve NI Water’s Annual Scheme of Charges.

The main purpose of this process is to make sure that charges are in line with the price limits determined under the associated price control, reflecting the delivery of services at lowest reasonable cost. The approval process includes a review of charges for the supply of drinking water, the collection, treatment and disposal of wastewater, road drainage and surface water, and the treatment and disposal of trade effluent.

We seek to ensure that there is no undue preference or undue discrimination by NI Water in setting charges between different customer groups.

The Scheme of Charges is the second to be based on the PC10 final determination which reduced the NI Water bid for funds by £91 million over the three-year period. While it was still necessary to increase prices over this period, the resultant increase in metered business bills was approximately 13% less (relative to 2009-10 prices) than the amount that NI Water originally sought.
