Holiday Let Owners: Your Essential Guide to Legionella Risk Assessments

Water safety isn't optional.
Most holiday let owners overlook this hidden danger until it's too late.
Why Your Holiday Let Needs a Legionella Risk Assessment
Ever wondered what happens in your water system when guests aren't around?
Empty properties create the perfect breeding ground for something dangerous lurking in your pipes.
Legionella bacteria thrive in stagnant water between 20-45°C, exactly what happens in unoccupied holiday lets. This invisible threat can cause Legionnaires' disease – a potentially fatal form of pneumonia that could devastate your business reputation and lead to serious legal consequences.
The law is clear: if you rent out property, you have legal responsibilities to ensure your tenants' health and safety by keeping the property free from hazards.
In Scotland, legislation now requires all holiday lets to have a Legionella risk assessment before councils will grant a licence. This trend is spreading across the UK as authorities recognise the serious risks posed by inadequate water safety management.

The Hidden Dangers in Your Holiday Let's Water System
Here's the thing...
Your property faces unique risks when it sits empty between bookings.
Water that doesn't move becomes dangerous. When your holiday let stands vacant for days or weeks, the water in your pipes, tanks, and appliances sits still – creating the perfect environment for Legionella bacteria to multiply.
The highest risk areas in your holiday let include:
- Hot water tanks and cylinders
- Rarely used taps and showerheads
- Decorative water features
- Hot tubs and spa pools
- Complex plumbing systems with dead legs
I discovered that holiday properties with irregular occupancy patterns face significantly higher risks than regularly occupied homes. The bacteria can multiply to dangerous levels in just 7-10 days of inactivity.
The real secret is that simple preventative measures, implemented through a proper risk assessment, can virtually eliminate these risks.
How to Protect Your Holiday Let and Guests
Simple systems are often the best.
Most holiday let owners overcomplicate water safety.
A proper Legionella risk assessment doesn't need to be complex or expensive. For most holiday lets, it involves:
- Identifying risk areas: Examining your water system to find potential Legionella breeding grounds
- Temperature checks: Ensuring hot water is stored above 60°C and cold water below 20°C
- System inspection: Checking for stagnant water, scale buildup, and proper insulation
- Documentation: Creating records to demonstrate compliance with health and safety regulations
- Preventative measures: Implementing simple control strategies to minimise risks
The Health and Safety Executive (HSE) states that "most landlords can assess the risk themselves and do not need to be professionally trained or accredited." However, if you don't feel confident, you can hire a specialist to conduct the assessment for you.
Nobody mentions that the most effective prevention strategy is also the simplest:
regular water system use. Flushing all outlets weekly when the property is vacant keeps water moving and dramatically reduces Legionella risk.
Your Legionella Risk Assessment Action Plan
Here's what you need to do right now:
- Understand your legal obligations: As a holiday let owner, you have a duty of care to ensure water systems are safe
- Conduct a risk assessment: Either do it yourself or hire a professional
- Implement control measures: Set proper water temperatures, flush systems regularly, clean showerheads
- Document everything: Keep records of your assessment and control measures
- Inform guests: Provide clear instructions about water system use
- Review regularly: Update your assessment whenever you make changes to the water system
Remember, if a guest were to contract Legionnaires' disease from your property's water system, you would need to demonstrate to a court that you fulfilled your legal duty by assessing and controlling the risks.
The most effective protection comes from understanding the specific risks in your property and implementing appropriate control measures.
Want to know the best part?
Most of these measures are simple and inexpensive to implement. The peace of mind they provide – knowing your guests are protected and you're legally compliant – is invaluable.
