In Scotland, Legionella is not just a background HSE issue for holiday accommodation. mygov.scot lists “Legionella risk standards” among the mandatory conditions short-term-let accommodation must meet, and says the accommodation’s risk from exposure to Legionella must be assessed [1].

That changes the way a host should hold evidence. A risk assessment tucked into an old maintenance folder is weak. The licence file should show the risk was assessed, what controls were set, how void periods are handled and who completes the water-safety tasks between guests.

The licensing position

Scottish short-term-let accommodation must meet mandatory conditions. If it does not, the host may not get a licence; if it falls below the standards while licensed, the council can add conditions or take enforcement action [1]. The mandatory-condition list includes repairing and tolerable standards, fire and safety standards, energy performance standards and Legionella risk standards [1].

For ordinary hosts, this does not mean a complicated hospital-style water safety plan. It means the water system in the accommodation has been looked at competently, the risks from showers, stored water, little-used outlets and empty periods have been identified, and the controls are being carried out.

Licence-file checklist

Keep these items in one place, with dates and names. A council or managing agent should not have to reconstruct the water-safety story from emails.

  • Legionella risk assessment: dated, property-specific and matched to the actual water system.
  • Outlet list: every tap, shower, hose, outside tap, bath, utility sink and hot tub or spa feature.
  • Storage and hot-water note: whether the property has cold-water storage, a cylinder, calorifier, combi boiler or private supply.
  • Void-period control: how water is flushed during empty periods and before guest arrival.
  • Changeover task: whether the cleaner, owner or agent runs taps and showers as part of the turnover process.
  • Showerhead routine: descale, clean, disinfect or replace schedule.
  • Private-water evidence: if the accommodation uses a private supply, keep the relevant Scottish private-water correspondence and testing/risk-assessment information with the licence file [4].
  • Action close-out: photos, invoices or notes for tank lids, redundant pipework, shower hose replacements and remedial work.

The point is not paperwork for its own sake. The licensing file should prove that the system is being managed during the exact periods that make short lets different from ordinary homes: empty weeks, sudden arrivals and high guest turnover.

What raises risk in a Scottish short-term let

The water source matters, but usage pattern is usually the bigger issue. A city flat occupied most weekends and supplied directly from the mains may be low risk once assessed. A rural cottage closed for winter, supplied from a private water source and fitted with a hot tub or little-used ensuite is a different system.

The same risk factors recur: water stored warm, water sitting still, pipework that no longer has real flow, scale and biofilm in showerheads, and aerosol-producing outlets [2][3]. Guests also do not know the building. They cannot be expected to manage a stale shower or report an odd hot-water issue before they have used it.

For that reason the host’s controls should sit in the operational rhythm of the let: booking calendar, changeover clean, winter closure, reopening and maintenance visits.

Where a managing agent or cleaner carries out the water tasks, write that into the operating procedure. A licence file that says “flush before arrival” is weaker than a record showing who does it, when they do it, and what they record if a tap, shower or hot-water system does not behave as expected.

FAQ

Does every Scottish short-term let need a Legionella assessment?

The Scottish licensing guidance says accommodation must meet Legionella risk standards and that the risk from exposure to Legionella must be assessed [1]. The assessment should be proportionate, but it should be property-specific and documented.

Is this different from a normal holiday-let duty?

Yes in evidence terms. HSE’s general landlord/person-in-control duty still matters [2], but Scottish short-term-let licensing makes Legionella risk standards part of the mandatory accommodation conditions [1]. Hosts should keep Legionella records with the licence evidence.

What if the short-term let has a private water supply?

mygov.scot says short-term-let accommodation with a private water supply must meet certain conditions and points hosts to DWQR private-water guidance [1]. Keep those private-water records beside the Legionella risk assessment; they answer different questions and neither replaces the other.

Next step

Take the licence file for one Scottish short-term let and add a water-safety front sheet: assessment date, next review date, outlet list, void-flush rule, changeover owner and private-water status. If one of those fields is blank, that is the first gap to close. For the broader short-let duty, read Do you need a Legionella risk assessment for a holiday let or Airbnb?.
