Hot tubs have become increasingly popular over the past decade, with places like Aldi and Asda regularly selling the device as special buys.
But if the proper checks are not carried out, the water can cause a range of dangerous infections – including legionnaires disease. This is a particular concern for people who rent out their homes to guests because they could end up with a huge bill that their insurance won't cover.
William McCarter, of rural insurance broker Lycetts, said: “All too often, people tend to skip over the small print regarding the potential health hazards. “If they ignore the regulations around taking water samples, and someone falls ill, their public liability insurance will be void and they could end up paying out thousands of pounds.”

He was highlighting his concern as owners look forward to an influx of summer guests. “Hot tubs are a big attraction for potential holidaymakers, and owners know that by providing them, footfall is likely to increase.
“However, hot tubs have environmental conditions that could potentially lead to the growth and dispersal of legionella and other infectious agents.”
The Health and Safety Executive specify how hot tub water should be tested and monitored, along with the quality and frequency of water inspections. McCarter added: “For those who offer – or are considering – hot tubs to enhance the holiday rental experience, ensuring all hygiene and safety regulations are adhered to is a must.
“They should also seek expert guidance from an insurance specialist. Local authority environmental health departments and the Health and Safety Executive have produced documents that detail the steps and checks that should be followed, and I strongly recommend owners read them.
“Everyone loves a hot tub, and being able to enjoy them safely means guests and operators can both relax.”
Experts say you should drain down and refill your tub around five times a year. But you should test its water around three times per week.
What is legionnaires disease?
It is a lung infection you can get from inhaling droplets of water from things like air conditioning or hot tubs. It's uncommon but it can be very serious.
According to the NHS website, symptoms of Legionnaires' disease include:
- a cough
- difficulty breathing
- chest pain
- a high temperature
- flu-like symptoms
