Is a Legionella Certificate a Legal Requirement for Landlords?

You may hear the term “Legionella certificate”, but the important requirement is to assess and manage the risk rather than simply purchase a particular certificate.

Routine Legionella water testing is also not automatically required for every normal domestic rental property.

For a straightforward rental home with a simple hot and cold water system, the risk may often be controlled through practical measures such as suitable temperatures, regular use of outlets and keeping showers clean.

Using a competent professional can be useful when you want an independent assessment and a clear written report for your property records.

We provide Legionella risk assessments for a wide range of residential and rental properties across London, including:

Every property is different, so the assessment is tailored to the size, layout and complexity of the water system.

Most normal rental homes have relatively straightforward water systems.

For example, a flat with a combi boiler and mains-fed cold water may present fewer potential areas of concern than a larger property with stored water, cylinders or longer pipework.

Even where the risk is low, landlords should still consider whether suitable control measures are in place.

Our assessment helps you understand the actual level of risk at your property without recommending unnecessary work.

HMOs can require more careful consideration because several people may share the same water system.

The property may have more showers and taps, greater hot-water demand, longer pipework runs and outlets that are used at different frequencies by different tenants.

During an HMO assessment, we consider factors such as:

A clear assessment helps landlords and property managers identify practical measures for controlling the risk.

Our assessor carries out a review of the property’s water system during the site visit.

Depending on the property, the assessment may include the following.

ACoP L8 is the Health and Safety Executive’s Approved Code of Practice and guidance relating to the control of Legionella bacteria in water systems.

It provides guidance for landlords, employers and other duty holders on managing Legionella risks.

Additional technical guidance is provided through HSG274.

Our Legionella risk assessments take relevant HSE guidance, including ACoP L8 and HSG274, into account.

There is no general rule stating that every Legionella risk assessment automatically expires after a fixed number of years.

The important point is that the assessment remains up to date.

A review may be appropriate when:

• The water system changes
• New pipework is installed
• A new boiler or cylinder is installed
• The way the property is used changes
• Occupancy changes significantly
• Existing control measures are no longer working
• Monitoring identifies a potential concern
• There is a suspected or confirmed case of Legionnaires’ disease

Keeping the assessment under review helps ensure that new risks are identified when circumstances change.

The appropriate control measures will depend on the property and its water system.

Common measures can include:

• Keeping hot and cold water at suitable temperatures
• Avoiding unnecessary water storage
• Flushing outlets that are rarely used
• Keeping showerheads clean and descaled
• Maintaining boilers and water systems
• Removing redundant pipework where appropriate
• Preventing water from remaining stagnant
• Following recommended maintenance procedures

Your assessment report will explain which measures are relevant to your property.
