The supply

Turn the dates and equipment you know into a practical water-supply plan.

Start with the council and supply details. If a date is missing, the result will keep it visible rather than guessing when the council last visited.

Private water FAQs

Useful dates, with the limits made clear.

Does a small holiday cottage need annual private water testing?

Yes, when it uses a private supply for commercial holiday letting. Mygov.scot says a supply serving a business or rental property must be tested by the council at least once a year.

Does a private laboratory sample replace the council test?

No. Extra testing can be useful, but the planner asks for the latest council test because the local authority runs the regulatory monitoring programme.

Is the five-year date a guaranteed council appointment?

No. It is a planning date calculated from the latest risk assessment you enter. Confirm the actual timing, monitoring, and any earlier review with the council.

Does the generated notice prove the water is safe?

No. The notice tells guests that the property uses a private supply and gives them practical contact information. Safety depends on proper risk assessment, treatment, maintenance, sampling, and incident response.
