Legionella control in office buildings
In a hybrid office the risk isn't the plant room. It's the half-empty floor, the cyclists' shower and the capped pipe nobody owns. Here's what to fix first.
Legionella control in office buildings
Office buildings are often seen as low risk, and many are, but that perception is exactly where problems start. Modern working patterns mean desks, kitchenettes, toilets and shower facilities can go unused for days at a time, and hybrid working has made stagnation a year-round issue rather than just a holiday one. The COVID-19 period showed how quickly water quality can deteriorate in buildings that empty out.
Many offices also have water coolers, bottle-filling stations and occasional-use showers that need to be included in the assessment rather than overlooked.
The duty to manage Legionella applies regardless of how low the perceived risk is. A proportionate programme means a suitable risk assessment, sensible temperature checks, flushing of little-used outlets, and keeping clear records. A digital logbook makes it straightforward to prove that routine tasks are actually happening across the building.
What makes this setting different
- Hybrid working leaves outlets unused for days at a time
- Stagnation is now a year-round rather than seasonal issue
- Water coolers and bottle-fillers are easily overlooked
- Low perceived risk leads to complacency and missed tasks
- Occasional-use showers generate aerosols
