Ask Lorraine – Legionella Certification. Surely, this isn’t a legal requirement for landlords?

🙋  Landlord’s Question: 

”Dear Lorraine,

I’ve just been talking to another landlord and he asked who I use to carry out my Legionella certification?  Surely he’s mistaken, this isn’t a legal requirement for landlords? If it is, why hasn’t it been all over the press.

Surely I don’t have to do this?

Lorraine’s Answer

Yes, this is a legal requirement, it started to apply for normal domestic properties in 2013. Guidelines state that the risk assessment must be carried out by a competent person, so there is no reason why you as that person cannot complete this yourself.

Review the risk assessment regularly as a matter of course and update it, should things change.

Simple control measures can help control the risk of exposure to legionella such as:

  • flushing out the system prior to letting the property
  • Cold water tanks should have tight fitting lids thus avoiding debris getting into the system
  • setting control parameters  to ensure water is stored at 60°C)
  • make sure any redundant pipework is removed

Why not send your tenants regular do’s and  don’ts information sheets on the control of legionella,  get them involved.

  • do clean  shower heads on a regular basis
  • do inform the landlord if the hot water is not heating correctly
  • don’t adjust temperature control settings of the calorifier
  • do run taps and shower heads if you leave the property empty more than a few weeks
