Commercial and Domestic Legionella Risk Assessments in Dundee & Tayside

Tayside’s towns and villages are mainly supplied by Backwater Reservoir (operated by Scottish Water) in Glen Isla. If you live in Tayside it’s likely that your water and sewerage services come from Scottish Water, the cost of which is included in your council tax bill.

Rural parts of Tayside may have a private water supply. This means that their water comes from a spring, borehole, well, river or loch rather than Scottish Water. The Drinking Water Quality Regulator for Scotland provides more information about private water management and treatment.

Since 1st April 2008, non-household customers could choose their water supplier in a bid to make water rates more competitive.

Regardless of where your water comes from, new Scottish legislation states that landlords who rent out entire properties or even a room within their home have a legal duty to ensure the health and safety of their tenants by conducting a Legionella Risk Assessment.

Any water system that stores and/or recirculates water is at high risk of breeding excess amounts of legionella. Below are a few water vessels that should be considered for a regular Legionella Risk Assessment.

  • Hot water tanks
  • Cold storage tanks
  • Hot tubs
  • Swimming pool

Dundee Legionella Risk Assessment FAQs

It is mandatory that landlords throughout Scotland, including Dundee and Tayside, risk assess their property to reduce the risk of exposure to Legionella. PHX offer full legally compliant Legionella Risk Assessments for landlords, homeowners, and commercial properties.

You are not legally obligated to review your Legionella risk assessment annually but it’s important to test your water from time to time in case anything changes.

The Legionella risk assessment can be carried out by anyone competent to do so. This could be the landlord or a specially trained water treatment company.

A Legionella risk assessment is different from water testing and water sampling. UK law applicable to the Tayside area requires you undertake a legionella risk assessment regularly in accordance with the Health and Safety Legislation at Work Act 1974 to show you are compliant with the HSE’s HSG 274 Legionella guidelines.

Following Legionella risk assessment, you may find that water testing or sampling is required as a precaution. Testing and sampling isn’t a legal requirement but may be necessary to ensure your water system is safe and to determine the most efficient way to manage your water system.

An L8 risk assessment and testing or sampling are best carried out together to maximise effectiveness and control.

A commercial Legionella risk assessment in Tayside can vary from £250 to over £750.

Domestic Legionella risk assessments vary widely depending on the size of the property, water assets present and whether properties are multiple or single landlord.

Legionella is commonly transmitted by inhaling contaminated water droplets. Air conditioning cooling towers, hot and cold water systems, humidifiers, showers and whirlpool spas are common culprits for harbouring legionella.

Legionella bacteria naturally occurs in Scotland’s water sources such as rivers, lochs, and reservoirs. It can infiltrate manmade water systems and breed in your water tank between temperatures of 20°C and 45°C .

When you inhale contaminated droplets, you’re at risk of catching Legionnaires’ disease. Legionnaire’s disease is a potentially fatal pneumonia that’s fatal in around 10% of cases. That’s why it’s important to conduct a regular risk assessment for Legionnaire’s disease.

You cannot usually contract Legionella from drinking contaminated water. It’s more likely to become infected by inhaling tiny droplets of bacteria that contain the infection although you can get Legionnaire’s disease from taps and showers that aren’t used often and where stagnant water gathers.
