What is Legionella?
The water-borne legionella bacterium is found in natural environments including ponds, rivers and lakes. However, if conditions are ‘right’, legionella can also establish itself in the mains water supply, where it can be distributed in the form of airborne droplets (aerosols), putting people at risk. The danger to humans is that if the legionella bacteria is inhaled, it can develop into the potentially fatal Legionnaires’ disease.
Risks from the legionella bacteria, therefore, need to be closely managed, and if you are in control of premises, you must be aware of the risks that it poses. There are a number of conditions that allow for the growth of the bacteria, including:
- Water temperatures between 20°C and 50°C
- Available nutrients (including sediment, biofilm, algae, scale, rust, material, etc.)
- Presence of biofilm on surfaces of water
- Poor or inadequate management or maintenance caused by lack of training and awareness
A water risk assessment will reduce the likelihood of the legionella bacteria spreading.

Legionnaires Disease
Legionnaires’ disease, which is also known as legionellosis, is a type of pneumonia. For those in the main risk groups, it can potentially be fatal – those most at risk are the elderly, people with suppressed immune systems, people over the age of 55, smokers, heavy drinkers or those suffering from diabetes, as well as those with chronic respiratory, heart or kidney disease.
The legionella bacteria can also cause other, less harmful illnesses such as Pontiac fever and Lochgoilhead fever, which can affect anyone.

Water Risk Assessment FAQs
When and how often do I need a water 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 with a risk assessment. Having a regular and sufficient risk assessment applies if you are a private Landlord and have rental properties which are occupied.
How much does a water risk assessment cost?
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 cold water system and location.
How long will the water 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 cold 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 the time spent on-site at your premises.
