What the rules say

Hot tubs used by paying guests are a known legionella risk. HSE guidance HSG282 covers domestic-style tubs used by a business, including holiday rentals, and sets out what HSE expects. You also need a written risk assessment and a written plan for how the tub is managed.

What to do

  1. Check pH and disinfectant at least twice a day while the tub is in use, and log the readings.
  2. Drain, clean and refill every week, or after each group of guests if sooner.
  3. Send a water sample to a UKAS-accredited lab every month for microbiological testing.
  4. Test for legionella at least every 3 months.
  5. Clean filters to the manufacturer's schedule and keep every record.

Tips from the field

  • Many hot tub servicing firms offer a monthly package that covers the sampling.
  • Give guests simple rules: shower first, time limits, no glass.

Common questions

What are the rules for hot tubs in holiday lets?

HSE guidance HSG282 covers hot tubs used by a business, including holiday rentals. You need a written risk assessment and a written plan for managing the tub, twice-daily checks while it is in use, regular water changes and laboratory testing.

How often should holiday let hot tub water be tested?

Check pH and disinfectant at least twice a day while the tub is in use and log the readings. Send a sample to a UKAS-accredited lab every month, and test for legionella at least every 3 months.

How often should the hot tub water be changed?

Every week, or after each group of guests if that is sooner.

Can guests do the hot tub checks?

You are responsible for the tub being safe, so it is better done and logged by you, a trained cleaner or a servicing company. Give guests simple rules too: shower first, time limits and no glass.

Will my insurance cover a hot tub?

Only if you tell your insurer about it. Many insurers ask for your testing logs and may exclude claims without them.
