Legionella Remedial Works


Your legionella risk assessment will identify all the risks that require corrective remedial works to reduce the risk of legionella growth in your water systems.

Legionella remedial works focus on improving the design of your water system by removing risks that encourage growth. Examples include system design, materials, stagnation, corrective measures.

Remedial works, therefore, include changes such as: removing redundant pipework, removing sources of nutrients (limescale), cleaning cold water storage tanks, insulating pipework, servicing Thermostatic Mixing Valves (TMVs) and so on.

Why do I need to do Legionella remedial works?


After undertaking the legionella risk assessment it will have identified a number of risk areas within your report, that you need to remove or remedy to reduce the risk of exposure to legionnaires disease.

So whilst you have undertaken the initial risk assessment, you must now take corrective measures to bring your water system into compliance with the Approved Code of Practice (L8) also known as the HSG 274. As part of your remedial actions legionella testing may also be necessary to determine if there is currently a legionella presence.

When do I need to do remedial works?


You will only need to carry out legionella remedial works once if actioned correctly. Should you make any additional changes to your water system it is important to consult with your water hygiene specialist to ensure the changes meet current regulations. However, legionella monitoring is an ongoing requirement where inspections and monitoring tasks should be carried out throughout the year. Periodic reviews of the legionella risk assessment should also be completed.

Legionella remedial works example – your legionella risk assessment might identify that your cold water storage tank has no lid or that you have a number of dead ends (pipework that has been capped off and allows the water to stagnate). By carrying out legionella remedial works you will have installed a new tank lid, and removed the dead ends reducing the risk of legionella growth. These works will not need to be carried out again.

How much does legionella remedial works cost?


Legionella remedial works costs vary from site to site. Depending on the remedial works identified in your legionella risk assessment will determine what works will be necessary, and therefore how much the works will cost.

If you feel your current water hygiene service provider is quoting you too much, contact our friendly team for a competitive quotation.

How long will the legionella remedial works take?


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 along with the amount of work that needs to be undertaken. But for an approximate duration contact our friendly team and they’ll be able to provide estimated timeframes.


Will I get anything to say the works were completed?


Yes, you’ll receive a site report with photos of all the completed works. This way you have evidence and proof of works, as opposed to a certificate which is not legally required. We aim to provide you with peace of mind through out customer service and proof of work.

What do I do after the Legionella remedial works?


By undertaking remedial works you will reduce the risk of exposure to legionnaires disease.  Once all the legionella remedial works are complete, you will then need to focus on implementing your legionella monitoring (periodical checks and maintenance) with a logbook for recording keeping all legal duties and monitoring requirements.

Legionella Remedial Work FAQs

Are legionella remedial works a one-off?

Once you have received your legionella risk assessment and have completed your remedial works to remove or reduce the identified risks, you won’t typically have to undertake the same works again. For example, installation of isolation valves, insulation, signage, etc.

You may however need to undertake further remedial action for ongoing tasks that may continue to change as time passes. For example, cold water storage tanks develop sediment, fill with scale, and debris over time. Temperature adjustments may be required over time. Thermostatic Mixing Valves (TMV’s) will require ongoing maintenance to ensure they remain within the compliant temperature range. And to ensure the filters are cleaned.

So whilst you won’t need to update or change the design of the water system, you will often need to continue with maintenance and service works. Also, if you change your water system in anyway, the works undertaken must be completed to the HSG 274 guidelines.

It is also worth bearing in mind that signage may fall off or be taken off by service users or customers, insulation may fall or become inadequate, or assets such as water heaters may fail and need replacing overtime.

In conclusion, whilst the majority of your remedial works won’t need further action, and you shouldn’t see them reappear in your legionella risk assessment. It is foreseeable to see cold water storage tanks requiring cleans in your legionella risk assessment every few years. Risk ratings can go from low to high from a lack of control and management from simple corrections. Non-compliant temperatures or heavy stagnant water may lead to high risk ratings from low as an example.
