Managing the Risk of Legionella in your Hot and Cold Water Systems

What is Legionella?

Legionella bacteria is commonly found in water. The bacteria multiply where temperatures are between 20°C to 45°C and nutrients are available. The bacteria are dormant below 20°C and do not survive above 60°C.

Legionnaires’ disease is a potentially fatal type of pneumonia, contracted by inhaling airborne water droplets containing viable Legionella bacteria. Such droplets can be created, for example, by: hot and cold water outlets; atomisers; wet air conditioning plant; and whirlpool or hydrotherapy baths.

Anyone can develop Legionnaires’ disease, but the elderly, smokers, alcoholics and those with cancer, diabetes or chronic respiratory or kidney disease are at more risk.


What do I need to do?

Woodlands Park has its own Legionella Management Policy and Legionella Risk Assessment which are reviewed annually and on an ad hoc basis where a change in practice or law deems it is necessary to do so.

To comply with our 2020 Legionella Risk Assessment review, we are now informing you as the ( Chalet or Lodge Owner who rents out their accommodation to the paying public) what your liabilities and responsibilities are, and what you action you need to take.

The action you need to take is simple and easy. It is your responsibility to ensure that you carry out the three actions detailed on the next page of this document if you are subletting your chalet or lodge to paying guests. You must also keep a record of your actions, to include the dates and times that you carried out your legionella management actions, because if one of your guests were to become ill in an alleged outbreak of legionella, the incident will need to be reported to the HSE (Health & Safety Executive)


Evidence would then need to be produced, to prove that you carried out your responsibilities which may be requested in a court of law.

Your record keeping can be as simple as recording the date and time that you descaled the shower head or recorded the temperature of the hot water or flushed the cold water system - and kept in a notebook assigned for this purpose. This can be delegated to your cleaning company but you must ensure that you tell them what you need them to do and check that they keep your records accurately for you - because whilst they then become accountable, you are still ultimately responsible, for ensuring the actions were carried out.

Legionella Hazard
Action Requiered


Shower Heads and Shower Hoses


Shower heads & shower hoses must be cleaned and de-scaled every 3 months


Hot Water Tanks

These can be found in most of the Lodges and also some of the Chalets


The hot water in the tank must be drained and replenished every month. Filling a bath will be sufficient to do this.

The hot water temperature must be 50C or higher, the temperature must be taken by running the hot tap.


Stagnant Cold Water


Where accommodation is not used for a period of over 7 days, the cold water system must be purged by a) flushing the toilet to empty the cistern and then b) running all the cold water taps & the shower for 10 minutes to flush the system through.
