Legionella Risk Assessments

Legionella bacteria, which causes the potentially fatal legionnaires disease, can be found in a range of types of water systems in the home and in nature. These bacteria thrive in hot and cold water tanks, and anywhere that water stands for an extended length of time.

This includes any branched pipes in your hot and cold water systems and a number of locations that can be caused by poor-quality installation of your water system.

If anyone inhales these bacteria through water droplets or other water ingestion, it can cause Legionnaires disease, which can be very dangerous.

It is important for the health and safety of key personnel and any people using the water system that appropriate control measures are in place to prevent legionella bacteria growth in your water systems.

You will also need to ensure that your plumbing is regularly checked for potentially risky areas and anything else that might be a health and safety issue. We are a team of experienced legionella risk assessment professionals with a real passion for safety.

We can help you to ensure that your hot and cold water system meets the requirements of your local health and safety legislation, and is free from dangerous substances, hazardous still water, and more.

Legionella Risk Assessment Costs

Legionella risk assessment cost levels start at around £250 for most water systems, although more complex systems may cost up to around £2,000 for a full risk assessment for legionella bacteria, depending on the health and safety executive involved.

All of our assessments for commercial and domestic premises follow all legal obligations and the approved code of practice for dealing with waterborne pathogens and contaminated water.

What Influences The Cost of a Legionella Risk Assessment?

The cost of a risk assessment for legionella bacteria can vary significantly, largely based on the size and complexity of your water system.

A normal domestic water system will be relatively affordable, but larger water systems, particularly ones that combine cold water systems and hot water systems, will take much more time to check over and recommend the appropriate control measures.

As such, these larger hot and cold water systems can be much more expensive to test.

Who Are Legionella Risk Assessments For?

Legionella bacteria can cause serious health problems, including Legionnaires’ disease, which can be deadly.

In the United Kingdom, every firm, regardless of size, is required by law to complete a legionella risk assessment in order to detect possible problems and keep employees, customers, and others safe.

This is true for all landlords, property managers, and company owners.

Landlord Legionella Risk Assessment

While most residential properties are at a very low risk of legionella bacteria, all landlords are legally required to perform regular legionella testing and routine risk assessment procedures.

Although there is no official certificate, landlords and property managers must keep the relevant paperwork on file and must be able to show proof that they have been regularly checking the water systems.

In most properties, the worst that is likely to appear is a bit of redundant pipework. Redundant pipe work carries a small risk of legionella bacteria and should be removed as soon as possible.

Properties with larger systems may require more frequent tests, however, particularly if they have cooling towers, evaporative cooling systems, a hot water cylinder, or complex thermostatic mixing valves.

These are all high risk for risky substances, hazardous environments, and bacteria growth, particularly in cooling towers.

Business Owner Legionella Risk Assessment

Businesses are legally required to identify potential risks and protect staff and customers from legionella. This means that, in a business with five or more employees, you should appoint a legionella responsible person to take care of legionella control and related health hazards.

It is a legal requirement for businesses to test for legionella as part of their legal duties. This is due to safety regulations in the Safety at Work Act.

The Safety at Work Act gives businesses a number of legal responsibilities to protect their staff, and ensuring that legionella tests are properly undertaken in a technically competent manner is a part of this.

Hospital Legionella Risk Assessment

Hospitals are, by nature, filled with people for whom exposure to legionella is a much higher risk than it is for most of the general public.

The elderly and those with immune system conditions are more likely to suffer a severe form of legionnaires disease than others if they risk exposure to legionella, so it is particularly important for hospitals to follow all relevant legislation very carefully.

In addition to this, hospitals and treatment centres are likely to have much more complex hot water systems, with large networks of pipes, spa pools, and a range of complex devices that produce water droplets connected to the water systems.

From the cold water tank to the spa pools, all of these must have high water quality at all times, and legionella control measures can be complex. It is vital to perform sufficient assessment on a regular basis to ensure the safety of your patients and staff.

Benefits of a Legionella Risk Assessment

A legionella risk assessment from a qualified engineer or a dedicated water treatment company has a range of benefits, from (hopefully) reassuring you that your property is low risk to pointing out potentially risky features that may be worth dealing with as part of your legionella control plan.

What Is a Legionella Risk Assessment?

A legionella risk assessment is a form of inspection that will check over your water systems to look for features that are typically high risk for legionella.

That includes “dead legs”, redundant piping, areas where the water temperature is consistently at a risky level, and much more. To learn more about the complexities of a full risk assessment, get in touch with our team today, and we can provide you with a free quote!

Why Is a Legionella Risk Assessment Important?

Health and safety matters and legionella bacteria can easily cause legionnaires disease, which can be fatal. A legionella risk assessment will show you if you are at risk, equipping you with all the information you need in order to protect yourself by taking appropriate steps.

How We Carry Out Our Legionella Risk Assessments

Before starting the process of completing a risk assessment, we will look over all of your previous legionella test paperwork to establish a baseline. Once we have done this, the actual testing process can begin. A legionella risk assessment is made up of three main parts.

First, we will carefully inspect every single water system on your property, both hot and cold systems. This will cover piping, storage vessels, taps, and all other parts of the system. Then, extremely precise temperature checks will be needed.

These will identify whether any of your water systems hold water at temperatures that might support the growth of legionella bacteria. The third and final stage is testing all areas of your home where water is aerosolised and can be found in droplets in the air.

That means toilets, taps, and more. We will test the area around the water sources and see if it is safe from bacteria.

Once all of this has been completed, we will put together a detailed report on all of the parts of the test. This includes full guidance on how to fix any issues detected and recommendations for further controls you may wish to put in place.

Frequently Asked Questions

Is it a legal requirement to have a Legionella risk assessment?

Yes. If you are a landlord or a business owner, legionella safety is paramount, and you are legally required to ensure that all water pipes and systems on your property are fully free from legionella.

This is part of your legal duty, and testing needs to be repeated on a regular basis. If you are a tenant, this is not your responsibility; your landlord should be taking care of it.

How often do I need a Legionella risk assessment?

In most cases, a legionella bacteria risk assessment should be completed once every two years. If there are major changes to the plumbing in your building, however, it may be advisable to perform additional checks on a more regular basis.

Larger systems with more complex pipework may need more frequent testing, particularly if they are in a healthcare setting where the potential risk from legionella is much higher. In these situations, an assessment roughly once every six months is recommended.

Can I do a legionella risk assessment myself?

Technically, it is possible to do your own legionella testing at home. However, if you are not an accredited professional, there is no way of guaranteeing the accuracy of your risk assessment and tests.

Instead, it is recommended that you engage the services of a professional to ensure that your system is, in fact, fully safe. To start the process of booking a risk assessment for Legionella, get in touch with our team today!

Who is at risk of legionella?

Legionella can cause Legionnaires disease, which can be very unpleasant for even a fully healthy adult but can be fatal to anyone more vulnerable.

This includes smokers, heavy drinkers, people over the age of 45, people with kidney issues or chronic respiratory issues, and anyone with any form of weakened immune system.

It can also be extremely dangerous for small children. Everyone is at risk to some extent, but these categories are in significantly more danger, and the risk of death for them is significant.
