Simple control measures can help manage the risk of exposure to legionella and should be maintained, such as:
- flushing out the system before letting the property
- avoiding debris getting into the system (e.g. ensure the cold water tanks where fitted have a tight-fitting lid)
- setting control parameters (e.g. setting the temperature of the calorifier to ensure water is stored at 60 °C)
- making sure any redundant pipework identified is removed
- advising tenants to regularly clean and disinfect showerheads.
L8MS designed an easy to use web platform, that can deliver a simple “proportionate” Legionella risk assessment for landlords.
The software assists Landlords/Letting & Management Agents:
- Who manage large numbers of units to achieve a common risk assessment template and risk rating method.
- Save time developing their own system.
- Minimising the time required to report risk assessment findings.
- All reports are stored and generated from the website.
- Control multiple assessors.
Assessors can ask questions of Graham Thompson and Alan Greaves if they come across something more challenging.
Some companies are offering to take a water sample from a domestic property and issuing a certificate to confirm it is legionella free
- A water sample is not a risk assessment
- It could be part of an assessment
- But it does not negate the requirement to produce a condition appraisal report of the condition of the water systems and fixed assets within the property.
