Are Your Hot Tubs Safe from Legionella? | LFS UK

Are Your Holiday Hot Tubs Putting Guests at Risk?

Hot tubs are a top attraction for holiday parks, glamping sites, and luxury lodges — offering relaxation and indulgence for guests looking to unwind. But beneath the bubbles, a silent threat could be lurking: Legionella bacteria.

At Legionella & Fire Safe Services, we work with accommodation providers across the UK to deliver routine hot tub water sampling, helping you eliminate risk, meet compliance standards, and protect your reputation.

🔹 Why Are Hot Tubs High-Risk?

Hot tubs provide the perfect storm for Legionella growth due to:

• Warm water: Most hot tubs are kept at 35–40°C — the ideal temperature range for Legionella bacteria to thrive.

• Jets and bubbling: These create aerosols — tiny droplets that can carry bacteria into the air.

• Mist and steam: Once airborne, Legionella can be easily inhaled, potentially leading to Legionnaires’ disease — a severe form of pneumonia.

Without proper monitoring and regular testing, your hot tubs could become a hidden health hazard.

🔹 What Is Legionnaires’ Disease?

Legionnaires’ disease is caused by inhaling water droplets contaminated with Legionella bacteria. It cannot be caught through drinking water — only by breathin

g in mist or vapour from a contaminated source, such as a spa pool or hot tub.

For vulnerable guests — such as the elderly, immunocompromised, or those with respiratory conditions — the risks can be severe or even fatal.

🔹 A Real-Life Tragedy: The 2015 B&Q Hot Tub Case

A high-profile case in 2015 revealed just how serious the risk can be.
Three men died after contracting Legionnaires’ disease traced to a contaminated hot tub on display at a B&Q store.
The store had failed to maintain the system properly, resulting in dangerous bacterial levels that led to infection through inhaled mist from the spa.

The DIY chain paid over £200,000 in damages, and the incident became a wake-up call for businesses across the UK.

🔹 Hot Tubs Are More Popular Than Ever

While the B&Q incident happened in 2015, the risk is greater today than ever before.

Since the COVID-19 pandemic, demand for private hot tubs in holiday rentals has skyrocketed.
A 2022 Direct Line report showed:

• Online searches for “UK holiday  with hot tub” experienced an 84 per cent increase.

• Google displaying over 23.3m results, so as a results show, having a hot tub is increasingly becoming a ‘must have’ for many guests when booking a holiday home.

With thousands more hot tubs in operation, especially in holiday lets and glamping retreats, routine sampling and monitoring is now essential, not optional.

🔹 What the Law Says

The Health and Safety Executive (HSE) requires all commercial hot tubs and spa systems to follow strict water management procedures under:

• COSHH (Control of Substances Hazardous to Health)

• L8 Approved Code of Practice

• HSG282 Guidance for Spa Pools

Failure to comply could result in fines, legal action, or harm to your guests.
