To report a leak, a burst main, no water or low pressure, call NI Water's Waterline on 0345 744 0088, which runs around the clock, or use the Report a leak link on the NI Water website. The website also shows current supply interruptions and planned work by area, so check it if your street has lost water. Give the exact location, when you first noticed the problem and whether neighbours are affected, and keep the reference number.

After a repair, NI Water says discoloured water can occur and is usually short-lived. If it does not clear, note how long it lasts at your tap and photograph it with the date visible.

Yes. The Consumer Council for Northern Ireland can investigate complaints from consumers in Northern Ireland about water services, and that includes NI Water's water supply, water pressure and water quality. It generally expects NI Water to have had the chance to put things right first, so keep a record of every call, email and letter.

Want every contact and reference ready in one place? Bring it through our complaint process: our trained AI opens a case for you and keeps coaching you on what to send NI Water and when to push again.

Be careful. Criminals have posed as NI Water staff to get into homes, saying they need to check the water supply. Real staff carry a photo ID card with their name, a serial number and the NI Water logo. NI Water says it never asks for bank details and never phones to say your water is unsafe unless you are on its customer care register.
