Quick answer
Stop work affected by unsafe or unavailable water and protect the food. Contact the water supplier and local food authority, read the actual notice and check every essential use, including handwashing, cleaning, ingredients, ice and drinks. Close affected operations when adequate safe facilities cannot be maintained. Bottled drinking water alone does not demonstrate that a food business can operate safely.
Water supports more than ingredients
Food-hygiene water requirements address an adequate safe supply and protection from contamination. Handwashing, cleaning, food preparation and equipment can all be affected.
Water/ice hygiene provisions explain the underlying supply principle. A working fridge or enough bottled drinks does not resolve failed handwashing or unsafe cleaning water.
Make the immediate decision
| Situation | Response |
|---|---|
| Supply stops | Stop work that depends on unavailable safe water; assess essential facilities. |
| Boil-water notice | Follow the exact instructions and confirm a suitable commercial operating method. |
| Do-not-drink/use instruction | Follow its restrictions; do not substitute an assumed boiling solution. |
| Ice/drinks/ingredient use | Stop affected production and assess any food already made. |
| Alternative arrangement | Check safety, capacity, facilities and authority advice before relying on it. |
| Unsafe operation | Close affected work/business as necessary until suitable conditions return. |
Read the actual notice
DWI advice for England and Wales distinguishes boil-water instructions from occasions when consumers are told to cease using water. Its domestic guidance is not automatic permission for a commercial kitchen to continue.
Use the supplier/authority instructions for your location and business, including private supplies. Do not assume a coffee machine, filter or improvised boiling arrangement meets the incident’s requirements.
Assess an alternative against all essential needs
Any alternative must provide adequate safe water and suitable facilities for the operation. Consider quantity, safe storage/delivery, required running handwashing facilities, temperature, cleaning and wastewater.
A historical council outage example required affected businesses without potable running water to close and rejected hand gel or bottled water alone as substitutes. Follow current local instructions; that incident is not a live alert or blanket judgement on every engineered alternative system.
Worked example: bottled water but dry hand basins
Hypothetical example: a café has bottled water for ingredients, but staff cannot use the required handwashing and cleaning facilities.
The manager stops affected food operations and obtains advice. Continuing open-food preparation because customers can still buy bottled drinks would leave the essential hygiene failure unresolved.
Verify safe conditions before restarting
Record the incident, affected food/ice, decisions and advice. Decide whether any food needs holding, disposal or further incident action.
Before restarting, follow notice-lifting and equipment instructions, including relevant flushing, cleaning, filters and ice/drinks-system recommissioning. Water returning to the tap does not override a remaining restriction or prove every food-contact system is ready.
Next steps
Keep supplier and local food-authority contacts in the emergency procedure. Review water-dependent tasks against the opening checks before resuming.
