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.

Annual Information Return

In support of our obligation to monitor the delivery of the undertakings contained in NI Water’s business plan, the company provides us with a comprehensive Annual Information Return (AIR).

We use this information to:
• monitor the company’s progress towards achieving higher quality objectives;
• monitor the company’s progress towards delivering the cost and performance targets set at each price control;
• ensure that customers’ standards of service are protected;
• compare company performance to other companies both now and over time;
• measure and compare their costs; and
• prepare for the next review of price limits.

Independent professionals (reporters and auditors) scrutinise the company’s information return and report their opinion to us.

These returns add additional scrutiny and robustness in relation to information that the company submits.
