Legionella Monitoring in Yorkshire

Yorkshire water risk,
one continuous record.
Leeds to the coast.

Across Leeds, Sheffield, Bradford, Hull, and York, AQUAIOT fits wireless temperature sensors at tanks, calorifiers, loops, and sentinel taps, checking readings against HSE L8 and HSG274 Part 2 continuously, from mill conversions to moorland estates.

Man-in-a-van visits leave gapsInspection sheets capture one moment. Between rounds, temperatures drift unseen, and your compliance record has no answer for it.
Legionella thrives between 20C and 45CRisk conditions develop and resolve between visits. Manual schedules cannot catch what happens overnight.
Audit prep should not take daysWhen an inspector asks for records, paper logbooks take days to compile. A digital audit trail is instant.

The AQUAIOT Solution

County-wide coverage,
from the mills
to the moors.

Yorkshire runs the full range of British building stock, converted mills in Leeds and Bradford, steel-era industrial sites around Sheffield, port estates in Hull, heritage stock in York, and rural buildings across the dales and moors. AQUAIOT holds them in a single live L8 record.

Continuous temperature profiling at tanks, calorifiers, loops, and sentinel outlets across Leeds, Sheffield, Bradford, Hull, and York estates.
Threshold alerts against HSE L8 guidance, SMS, email, and app notification the moment a reading drifts into a risk zone or a flush is missed.
One dashboard for the whole county, with tamper-evident audit trails and API, BMS, and CAFM integration.

How It Works

Three steps to continuous L8 compliance

Step 01

Monitor

AQUAIOT sensors are deployed at tanks, loops, calorifiers, and sentinel outlets. Temperature is profiled continuously, every reading timestamped and logged to the cloud over secure cellular or LoRaWAN telemetry.

Step 02

Alert

When temperatures drift outside HSE L8 thresholds, or when a scheduled flush is missed, AQUAIOT triggers an immediate alert via SMS, email, or app, with role-based escalation rules for your estates team.

Step 03

Record

Every reading, alert, and action is captured in tamper-evident audit logs. Records are exportable on demand and integrate with CAFM, BMS, and AIMS systems, so audit preparation is minutes, not days.

Capabilities

Everything your L8 programme needs

Purpose-built for estates, facilities, and compliance teams managing water systems across single or multiple sites.

Real-time temperature profiling

Continuous monitoring at tanks, calorifiers, loops, and sentinel outlets. Every reading timestamped and stored, never a gap in your record.

HSE L8 threshold alerting

Thresholds checked against HSE L8 and ACoP guidance. Alerts fired immediately when cold water exceeds 20C or hot water falls below 50C at point of use.

Missed-flush detection

AQUAIOT detects when scheduled flushing routines are not completed and generates an automatic alert, so no event is undocumented.

Tamper-evident audit trails

Every reading and action is logged with a secure, unalterable timestamp. Exportable records ready for audit, inspection, or HSE enquiry at any time.

API / BMS / CAFM integration

Open and interoperable. AQUAIOT connects to your existing SCADA, AIMS, CAFM, and BMS platforms via RS485/Modbus or REST API, no lock-in.

Retrofit-friendly deployment

Non-invasive sensors designed for live environments. No pipe cutting, no shutdown. AQUAIOT engineers handle site survey, installation, and commissioning.

Who It’s For

Built for the teams responsible

Housing Providers

Protect tenants. Prove compliance.

Housing associations and registered providers carry a statutory duty of care over water systems in their properties. Manual L8 management across multiple sites is operationally fragile, and increasingly under scrutiny.

  • Continuous monitoring across all properties, single dashboard view
  • Automatic alerts when vacant properties develop risk conditions
  • Audit-ready records for insurance, regulatory, and legal purposes
  • CAFM and property management system integration
NHS & Public Sector

Clinical-grade water safety. Without the admin burden.

NHS Estates and public sector facilities operate under HTM 04-01 and HSE L8 obligations. The complexity of large estates, multiple buildings, and dense pipework makes manual monitoring inadequate at scale.

  • Dense outlet coverage across clinical environments
  • Real-time temperature monitoring at thermostatic mixing valves and outlets
  • Integration with existing BMS and CAFM infrastructure
  • Automated compliance records compatible with HTM 04-01 requirements
Facilities & Estates

Less time on rounds. More time on management.

Commercial estates, universities, leisure facilities, and large offices face the same challenge: manual L8 inspection rounds are resource-intensive and provide only a snapshot. Automation changes that calculus entirely.

  • Replace labour-intensive manual rounds with automated monitoring
  • Role-based dashboard access for estates managers, deputies, and contractors
  • Reduce reactive call-outs, detect issues before they escalate
  • On-demand compliance reports for building managers and insurers
Defence & Secure Sites

Secure by design. Compliant by default.

Defence estates, MoD sites, and government facilities carry the same L8 duty of care as any other property, often across aging, complex pipework that is hard to reach and harder to document. Manual rounds leave gaps AQUAIOT closes permanently.

  • Encrypted telemetry, cellular and LoRaWAN with secure payload transmission
  • Tamper-evident immutable logs with timestamps and user actions
  • Role-based dashboard access, right records to the right people
  • Auditable compliance records meeting MoD and government estate requirements
Open, interoperable systems. No lock-in. Engineered for operational environments.

Questions & Answers

Legionella monitoring across Yorkshire, answered

Do you cover the whole of Yorkshire?
Yes. AQUAIOT engineers survey, install, and commission across Leeds, Sheffield, Bradford, Hull, and York, and throughout North, South, East, and West Yorkshire, as part of UK-wide coverage. Once commissioned, monitoring is fully remote, so a moorland site reports as continuously as a city-centre tower and rounds stop being a scheduling exercise.
Which Yorkshire sectors do you typically work with?
Yorkshire spans NHS estates, universities, large social housing stock, manufacturing, port and logistics sites around Hull, and heritage buildings in York. Each carries an L8 duty of care, and continuous monitoring suits a county where one portfolio can hold a Bradford mill conversion, a Sheffield industrial unit, and a rural estate at once.
Can you monitor mill conversions and heritage stock?
Yes. Converted mills in Leeds and Bradford and older stock in York run long, reworked pipework with dead legs that manual rounds struggle to reach. Wireless sensors retrofit at tanks, calorifiers, loops, and sentinel outlets with no pipe cutting, which suits listed and heritage buildings where invasive work is undesirable.
Can you monitor rural sites across the dales and moors?
Yes. Sensors report over cellular or LoRaWAN telemetry with encrypted payloads, so remote rural buildings appear on the same dashboard as urban stock. Where mobile signal is weak, a LoRaWAN gateway carries the readings instead. Distance stops deciding how often a site gets a reading, because every site reports continuously.
Can sensors be fitted without shutting down our water system?
Yes. The sensors retrofit into live buildings with no pipe cutting and no shutdown, so occupied housing, wards, offices, and student blocks across Yorkshire keep running through installation. Engineers fix them in a normal working visit, and each sensor reports to the dashboard from the moment it is commissioned.
Does it integrate with our existing BMS or CAFM system?
Yes. AQUAIOT connects to BMS, CAFM, AIMS, and SCADA platforms over RS485/Modbus or REST API, so Yorkshire estates teams keep one source of truth without lock-in. Records and alert histories export cleanly for audits, and role-based dashboards cover the teams who work outside those systems day to day.
