A boil-water notice is a specific instruction about an affected supply. It does not mean every water problem can be solved by boiling. Read the actual notice, including its area and start time, and follow the supplier's directions until it is officially lifted.

Identify affected activities

Drinking is not the only use that may matter. Food preparation, teeth cleaning, ice, feeding equipment and pet water can also be relevant. Use the supplier's instructions and the Drinking Water Inspectorate's guidance to understand the notice. If you are unsure whether your address is included, contact the supplier.

  • Tell visitors and carers before they use the tap.
  • Put a clear reminder near affected taps if helpful.

Work around lost power

A notice may coincide with an electricity interruption. Use a suitable alternative supply if you cannot boil water safely in line with instructions. Do not bring a camping stove or barbecue indoors, and do not assume a domestic filter makes the restriction unnecessary. Medical and infant-feeding needs require their relevant professional guidance.

Wait for official clearance

The return of pressure or clear-looking water does not lift the notice. Check the official update and any instructions for appliances, ice or stored water after restrictions end. Dispose of or handle affected items as directed. Keep a brief note of the advice and time if several people manage the home. For a do-not-drink or do-not-use notice, follow that different instruction exactly; boiling may be inappropriate for the problem involved.
