Little-used rooms sit and stagnateRooms left empty between bookings let water sit in pipes and warm into the growth range. Manual rounds rarely reach every quiet room before the next guest checks in.
Seasonal occupancy swings the riskQuiet seasons leave whole floors lightly used, then occupancy surges. The water risk profile changes faster than a fixed manual schedule can follow.
Spa and pool areas raise the stakesWarm, aerosol-generating spa and pool environments carry heightened Legionella risk and demand closer attention than a periodic round provides.
Reputation rides on getting it rightA water-safety incident is a guest-safety and reputational event. Gaps in your compliance record are a risk to the brand as well as a legal one.
The AQUAIOT Solution

Continuous visibility.
Automatic records.
Reputation protected.

AQUAIOT replaces manual rounds with continuous automated monitoring across rooms, loops, and spa areas, so your L8 record stays current through every occupancy swing and is always ready for inspection.

Real-time temperature profiling at tanks, loops, sentinel outlets, and spa areas, continuous rather than periodic.
Threshold alerts against HSE L8 and HSG274, immediate SMS, email, and app notification when a little-used room develops risk or a flush is missed.
Tamper-evident, exportable audit trails, instant evidence for inspectors, insurers, and brand standards audits.

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 every kind of hospitality operation

Hotel Groups

Brand standards across every property.

Hotel groups must hold consistent water-safety standards across many properties with varied building stock and local teams. Manual monitoring at this scale is fragile and hard to standardise across the estate.

  • Continuous monitoring across every hotel from a single dashboard
  • Standardised records and alerts across the whole group
  • Role-based access for group compliance leads and on-site teams
  • Audit-ready evidence for brand standards, insurers, and inspectors
Independent Hotels

Compliance without a compliance team.

An independent hotel carries the same L8 duty of care as a major chain, usually without dedicated compliance staff. Automation gives a small team a reliable record without adding rounds to a busy operation.

  • Automated monitoring without adding to staff workload
  • Immediate alerts when little-used rooms develop risk conditions
  • Audit-ready records ready for inspection at short notice
  • Retrofit-friendly install with no shutdown of the water system
Spa & Leisure

Close watch on higher-risk areas.

Spa, pool, and wellness areas combine warmth and aerosol generation that raise Legionella risk, demanding closer monitoring than a periodic round can provide across these sensitive environments.

  • Continuous profiling at spa, pool plant, and associated outlets
  • Immediate alerts when temperatures drift outside HSE and HSG274 guidance
  • Tamper-evident records for the responsible person and inspectors
  • Cellular and LoRaWAN telemetry across leisure plant areas
Serviced Apartments

Coverage across uneven occupancy.

Serviced apartments see units occupied and vacated unevenly, with kitchenettes and ensuites that can sit unused for long stretches. Continuous monitoring tracks risk room by room without manual rounds.

  • Continuous profiling across individual units from one view
  • Automatic alerts when vacant units develop risk conditions
  • Documented evidence that water is safe before a new stay begins
  • Exportable evidence for operators, owners, and insurers

Questions & Answers

Legionella monitoring for hotels, answered

How does automated monitoring support HSE L8 and HSG274 in hotels?
AQUAIOT records temperatures continuously at tanks, loops, sentinel outlets, and spa areas and checks them against HSE L8 and HSG274 Part 2 guidance. It strengthens the duty holder’s written scheme of control with a complete, tamper-evident record, while responsibility for the overall control scheme remains with the operator.
How does it handle rooms that sit empty between bookings?
AQUAIOT profiles little-used rooms continuously and sends an immediate alert when temperatures drift into risk conditions, so quiet rooms between bookings are covered without relying on a manual round reaching every door.
Can it monitor spa and pool areas as well as guest rooms?
Yes. Coverage includes spa, pool plant, and associated outlets alongside tanks, loops, and sentinel outlets, with closer profiling of the warmer, higher-risk areas that HSE and HSG274 guidance highlights.
Can sensors be fitted without disrupting guests?
Yes. AQUAIOT sensors are designed for retrofit in live environments, with no pipe cutting and no shutdown required. Our engineers handle the site survey, installation, and commissioning around the running of the hotel.
How quickly can we produce records for an inspection or brand audit?
Every reading and alert is held in tamper-evident logs with secure timestamps and is exportable on demand, so producing evidence for an inspection, insurer, or brand standards audit takes minutes rather than days.
Is it suitable for a group as well as a single hotel?
Yes. AQUAIOT scales from one independent hotel to a multi-property group, with continuous monitoring visible from one dashboard and role-based access for on-site teams and group compliance leads.
