Legionella Monitoring for Offices in Leeds

Leeds offices,
monitored without the rounds.
No clipboard, no gaps.

Serving offices across Leeds, from the financial and legal quarter to converted mills, riverside blocks, and business parks, AQUAIOT fits wireless temperature sensors at cold water storage tanks, calorifiers, hot and cold loops, TMVs, and sentinel outlets, checking readings against HSE L8 and HSG274 Part 2 without a single manual round.

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

Automatic readings
across Leeds
office floors.

Walking every washroom, teapoint, and plant room across a Leeds office building eats FM hours, and hybrid occupancy means half those visits find floors empty anyway. AQUAIOT takes the routine readings automatically, so engineers attend to fix things, not to hold a thermometer against a pipe.

Real-time temperature profiling at tanks, calorifiers, loops, TMVs, and sentinel outlets across Leeds office floors, with no manual rounds.
Threshold alerts against HSE L8 guidance, SMS, email, and app notification when a reading drifts or a scheduled flush is missed, wherever the team is.
Tamper-evident, exportable audit trails, with API, BMS, and CAFM integration so weekly reporting for Leeds office buildings takes minutes, not a shift.

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 for offices in Leeds, answered

Do you cover offices across Leeds?
Yes. AQUAIOT engineers carry out surveys, installation, and commissioning across Leeds and West Yorkshire, as part of UK-wide coverage. We work in the financial and legal quarter, converted mills, riverside developments, and out-of-town business parks, for owners, FM providers, and occupiers.
Does continuous monitoring reduce manual temperature rounds?
Yes, substantially. Sensors take the routine sentinel, tank, calorifier, and loop readings that currently justify a walk-round, and log them far more often than any rota could. Site visits then happen to investigate and fix flagged issues rather than to collect numbers, which reduces routine attendance across a Leeds office building.
Can one FM team watch several Leeds buildings at once?
Yes. Multi-site dashboards bring every monitored building onto one screen with role-based access, so a single Leeds FM team sees temperatures, alerts, and outstanding actions across the whole portfolio. Reporting exports per building or per portfolio, which suits teams covering scattered offices with limited engineers.
Do you monitor showers, teapoints, and low-use office outlets?
Yes. Cyclist showers, accessible washrooms, and teapoints on quiet floors are classic office stagnation points because days can pass between uses. Sensors at these sentinel and infrequent outlets track temperatures continuously and flag missed flushing, so the outlets least visited by staff are the best evidenced.
What happens when a flush is missed?
The platform notices the outlet has not seen its expected use or temperature event and raises an alert by SMS, email, or app, routed by role with escalation if nobody responds. The miss and the follow-up action both enter the tamper-evident log, so the L8 record shows the exception and its resolution.
How does this support our HSE L8 duty?
Every reading is checked against HSE L8 and HSG274 Part 2 guidance the moment it is taken, and drift or missed flushing triggers an alert rather than waiting for the next round. The resulting tamper-evident record strengthens your written scheme of control, while the duty holder remains responsible for the scheme overall.
