ResourcesHSG274 check guide
The routine checks, in one table.
The hot and cold water checks from HSE’s HSG274 Part 2, Table 2.1, as Ecohydro’s templates set them up. They are defaults: your risk assessment sets the frequency for your buildings.
Reading the table
Defaults, not rules
HSG274 says the risk assessment decides how often each check is done. Every template can be changed, with the reason recorded.
Rotations
Representative outlets are checked a few at a time, so every outlet is covered once a year without checking them all each month.
Where HSE sets no frequency
For representative outlets and TMVs the table gives no interval. Our default is marked as ours.
| Check | Default frequency | Target |
|---|---|---|
| Calorifier flow temperature | Monthly | At or above 60 °C |
| Calorifier return temperature | Monthly | Not below 50 °C |
| Hot water sentinel outlets | Monthly | At least 50 °C within one minute (55 °C in healthcare premises) |
| Cold water sentinel taps | Monthly | Below 20 °C within two minutes |
| Principal loop return temperatures | Monthly | At least 50 °C (55 °C in healthcare premises) |
| Subordinate loop return temperatures | Quarterly, on a monthly rota | At least 50 °C |
| Hot water representative outlets | Each outlet once a year, monthly rota (our default) | At least 50 °C (55 °C in healthcare premises) |
| Cold water representative outlets | Each outlet once a year, monthly rota (our default) | Below 20 °C |
| Cold water tank and mains temperatures | Yearly, in summer | Below 20 °C |
| Flush infrequently used outlets | Weekly | Until the temperature stabilises |
| Clean and descale showers and spray taps | Quarterly | Heads, inserts and hoses clean |
| Cold water storage tank inspection | Yearly | Inspected, remedial work where needed |
| Calorifier inspection and clean | Yearly | Inspected and cleaned, or debris purged |
| TMV service | Yearly (our default) | Serviced and fails safe, per the manufacturer |
Always check the source
This is a summary to help plan routine work. Read HSG274 Part 2 and follow your written scheme and risk assessment.
