Legionella Risk Assessments in Kent & South East London: A Landlord’s Legal Responsibility

Let’s be honest, Legionella Risk Assessments aren’t usually top of a landlord’s priority list. But if you own a rental property in Kent or South East London, it is something you’re legally responsible for.

I regularly speak to landlords across Dartford, Bexley and the surrounding areas who didn’t even realise it was something they needed to consider. If that’s you, you’re not alone, but it is something worth getting right.

What is Legionella—and why does it matter?

Legionella is a bacteria that can develop in water systems, particularly where:

• Water is stored
• Outlets are used infrequently
• Temperatures sit within certain ranges

If inhaled through tiny water droplets (for example from showers or taps), it can cause a form of pneumonia known as Legionnaires’ disease, a potentially serious lung infection. It is particularly dangerous for older people and those with weakened immune systems.

This means it’s not just a “large or commercial building” issue, it can exist in any rental property, from a one-bed flat to a multi-let HMO.

Do landlords need a Legionella Risk Assessment?

Yes—landlords have a legal duty to assess and manage the risk of Legionella in their properties.

That doesn’t necessarily mean a full report is required in every case, but it does mean you need to be able to demonstrate that the risk has been properly considered and addressed.

Can landlords carry out their own assessment?

Technically, yes.

But in reality, many DIY assessments miss key risk areas.

For example:

• Do you know how to identify a dead leg in pipework?
• Are you able to accurately test water temperatures?
• Would you recognise issues within a water tank or cylinder?

If not, it becomes guesswork and from a compliance point of view, that’s not a great position to be in.

What does a professional Legionella Risk Assessment involve?

When I carry out a Legionella Risk Assessment, it’s not just ticking boxes. I carry out a full inspection of the property, including:

• Checking all water outlets, including low-use taps and showers
• Identifying areas where water may stagnate
• Inspecting tanks and cylinders
• Testing hot and cold water temperatures

The aim is simple: identify any risks and provide clear, practical recommendations.

Why use a professional assessor?

The biggest benefit isn’t just the inspection, it’s the documentation.

A professionally completed assessment provides a clear record that you’ve taken your legal responsibilities seriously. This can be important if a tenant raises concerns or if you ever need to demonstrate compliance.
