Free Legionella Temperature Log Template (HSG274) — PDF & Excel
Monthly sentinel temperatures, calorifier checks and flushing records — the HSG274 monitoring evidence your risk assessment calls for.
Your legionella risk assessment is only as good as the monitoring that backs it. This log covers the three records HSG274 Part 2 expects for hot and cold water systems: monthly sentinel-outlet temperatures, calorifier flow/return checks, and flushing of infrequently used outlets.

The targets, printed on the sheet
- Hot water: ≥50°C within 1 minute at the tap (55°C in healthcare)
- Cold water: ≤20°C within 2 minutes
- Calorifier: flow ≥60°C, return ≥50°C
How to use it
Your risk assessment defines the sentinel outlets — list them once, then work through monthly. Record failures with the action taken; a reading out of range with no action is worse evidence than no reading at all. Keep monitoring records at least 5 years.
