Hi,
We would be classed as low risk for legionella due to the combi boilers / not having water tanks; however, the legionella people have classed us as medium risk because residents are generally older.
I have purchased a water thermometer and check the hot and cold kitchen taps every month, recording the results.
It’s a bit of a pain, but I combine it with my monthly visit to the residents and stand at their kitchen sink while we chat, so it’s not too onerous.
Without checking my records, I have a feeling that the legionella company come out every five years to do a more in-depth check.
