Legionella Risk In Commercial Offices
Legionella bacteria is the cause of the potentially fatal Legionnaires’ disease, a severe form of pneumonia, as well as other, less serious fevers. Legionnaires’ disease can affect anyone who comes into contact with the bacteria. Legionella is found in low numbers in natural water sources, but when confined to purpose-built water systems, can multiply, unless appropriate measures are taken to control the risks by storing the water at the correct temperature. The bacteria is usually contracted by inhaling small drops of water that have been suspended in the air. It grows in temperatures between 20–45°C which means cold water must be stored at lower temperatures and hot water at higher temperatures. It can also grow in deposits such as sludge, rust, scale and other organic matter, so it’s important to keep water systems clean at all times.
All commercial offices have water on-site and will, therefore, need to carry out regular legionella risk assessments, whatever the age of the building or water system. Assessments should be undertaken every two years, and water systems monitored on a regular basis. We can undertake the risk assessment, regular monitoring on your behalf and help you understand more about the legionella bacteria.
What is Legionella?
The legionella bacteria is found in natural environments including ponds, rivers and lakes. The legionella bacteria can also be supplied in small amounts within the mains water supply. Where there are water and the conditions of creating water droplets (aerosols), people using or within the area of these services may be at risk. It is this bacteria found in the water supply which is the cause of Legionnaires disease.
Where there is a potential for legionella risk, there is an absolute need to manage and mitigate this and according to the HSE “if you are an employer, or someone in control of premises, including landlords you need to be aware of the risks that legionella poses.”
Conditions and contributing factors to legionella bacteria growth include:
- Temperatures between 20-45°C
- Available nutrients (including sediment, biofilm, algae, scale, rust, material, etc.)
- Presence of biofilm on surfaces of water
- Poor or inadequate management including training and awareness

Legionnaires disease, also known as Legionellosis, is a type of pneumonia, which can potentially be fatal. Those most at risk are the elderly and the very young, male over 50’s, the ill and smokers to name a few. Legionella bacteria can also cause other, less harmful illness such as Pontiac fever and Lochgoilhead fever, which can affect all people.
The main route of infection of legionnaires disease is through inhalation, by inhaling airborne water droplets that contain legionella bacteria. It cannot be spread from person to person and the majority of cases or outbreaks of legionnaires disease have been via domestic water services, evaporative cooling towers, and spa pools.
It is also important in residential properties to regularly assess your water systems in your property, especially where water systems have been stagnant for some time. As a tenant, if you are renting you may have been advised on legionnaires disease by your estate agent when signing the lease amongst all the paperwork, but ultimately it is a landlords’ responsibility to ensure that a legionella risk assessment is carried out on their properties. If you are a Landlord it is a legal requirement for you to ensure a legionella risk assessment is carried out on your rental properties for the health and safety of your tenants and to remove the legionella bacteria from the water systems.

L8 Risk Assessment FAQs
When and how often do I need a risk assessment?
Under the Health and Safety at Work Act 1974 and in compliance with the Approved Code of Practice (ACoP L8, HSG 274), duty holders, including employers and those in control of premises, must ensure the health and safety of their employees or others who may be affected by their undertaking, this includes the risk of legionella. Legionnaires Disease is a form of pneumonia, which can be fatal and the main route of infection is through inhalation, by inhaling airborne water droplets that contain Legionella. This also applies if you are a private Landlord and have rental properties which are occupied.
This includes taking suitable precautions to prevent, manage and control the risk of exposure to legionella. You can do this by undertaking the following: a risk assessment, actioning all identified risks within the initial report with remedial works, sampling the water quality to confirm bacterial presence with water testing, and carrying out ongoing record keeping also known as monitoring.
Do I need testing, a risk assessment or both?
Legionella testing, water testing or sampling is not to be confused with a legionella risk assessment. You are required by law to undertake a legionella risk assessment under the Health and Safety at Work Act 1974, COSHH and a number of other regulations where you can show you are working to comply with the HSE’s HSG 274 legionella guidelines.Testing or sampling whilst not a legal requirement on it’s own, it plays an important role in determining how efficient a water system is managed. Your risk assessment may identify that sampling is required due to existing risks or as a control and management precaution. In this instance sampling then becomes a requirement from your assessment. Without an L8 risk assessment you will not know where and how many samples are required. And without water testing/sampling you cannot determine how affective your control and management is. These two actions therefore should be undertaken together, not necessarily at the same time but unison to effectively management your risk from legionella.
Water testing services include Legionella, e-Coli, total viable count (TVC), Pseudomonas, hard water, chlorine free, pH levels and more. Learn more about legionella testing. We only use UKAS approved laboratories giving you peace of mind that the test will be of the highest quality possible.
How much does an L8 risk assessment cost?
All assessments vary in prices depending on the number of water outlets, cold water storage tanks, hot water cylinders, combi boilers and other water assets that may be present. The number of assets within your water system will determine the time spent on site and how long it will take to produce your report.
So how much does it cost? Across the industry, prices vary enormously often depending on the size of the company you use and their processes, the speed of works and professionalism. There are two types of assessments, the first is commercial and the second domestic, also referred to as residential rental properties or landlord risk assessments.
Commercial risk assessments normally start from £250 to in excess of £750, however our prices start from £99 depending on the size of the water system and location.
Domestic risk assessments can range tremendously with a number of plumbers, gas engineers and other tradesmen offering these assessments without the specialist training, it’s important to check that your assessor or engineer is properly qualified. Our prices start from £55 for multiple landlord properties to £95 for single landlord properties. Our prices for residential rental properties are based on the property being no more than 5 bedrooms.
How long will the risk assessment take?
On average, the time our qualified assessor spends on site is 1 hour for every 10 outlets (sinks, showers, baths, etc). So an assessment can take anywhere between 30 minutes to 6 or 7 hours. It entirely depends on the size of your water system and the number of water assets you have such as cold water storage tanks, cylinders or combination boilers.
Our engineers will work closely with you to ensure minimal disruption to your business is caused. Clear and easy access to rooms and buildings will play a part in time spent on site at your premises.
When will I receive your findings?
You will receive your LRA report between 2-10 working days from the date the assessment was carried out. From time to time, not often, our team will need a little more time, so please expect to have your report no later than 30 days. Need your assessment sooner? Get your report, guaranteed next day delivery via email for just £50.
What happens after I receive the report?
Within your report document, you will have an action plan offering guidance which lists all identified risks, with photos, that need remedying in order of importance. By following our advice and undertaking remedial works you will reduce the risk of exposure to Legionnaires’ disease. Once all the remedial works are complete, you will then need to focus on implementing your monitoring (periodical checks and maintenance) with a logbook for recording keeping all legal duties and monitoring requirements.
