Residents are among the most vulnerableCare home residents are often elderly and immunocompromised, the group most exposed to waterborne infection. A temperature that drifts between visits puts the people in your care at risk.
TMV scald risk runs alongside L8Thermostatic mixing valves must hold safe outlet temperatures for frail residents while hot water still runs hot enough to control Legionella. Manual checks rarely watch both at once.
Quiet rooms and voids stagnateEmpty rooms, low-use ensuites, and unoccupied wings let water sit and warm. Between manual rounds, stagnation builds unseen.
CQC and insurers expect clean recordsWhen a CQC inspector or insurer asks for temperature history, paper logbooks take time to compile and one missing entry undermines the whole record.
The AQUAIOT Solution

Continuous visibility.
Automatic records.
Safer residents.

AQUAIOT replaces time-consuming manual rounds with continuous automated monitoring, so your L8 record stays current, supports your CQC duty of care, and is always ready for an inspector or insurer.

Real-time temperature profiling at tanks, loops, thermostatic mixing valves, and sentinel outlets, continuous rather than periodic.
Threshold alerts against HSE L8 guidance, immediate SMS, email, and app notification when temperatures drift into risk zones or a flush is missed.
Tamper-evident, exportable audit trails, ready for CQC inspections, insurers, and your written scheme of control.

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 care provider

Care Home Groups

One dashboard across every home.

Care home groups manage L8 duty of care across many sites with varied building stock and stretched maintenance teams. Manual monitoring at this scale is operationally fragile and hard to standardise.

  • Continuous monitoring across every home from a single dashboard
  • Standardised records and alerts across the whole portfolio
  • Role-based access for group compliance leads and home managers
  • Audit-ready evidence for CQC, insurers, and head office governance
Single Homes

Compliance without a compliance team.

An independent home carries the same L8 and CQC duty of care as a large group, usually without dedicated compliance staff. Automation gives a small team a reliable monitoring record without adding rounds.

  • Automated monitoring without adding to staff workload
  • Immediate alerts when outlet temperatures drift into risk zones
  • Audit-ready records ready for CQC inspection at short notice
  • Retrofit-friendly install with no shutdown of the water system
Supported Living

Coverage across dispersed living settings.

Supported living schemes spread residents across flats and shared houses where outlets are used unevenly and stagnation risk varies room by room. Consistent manual monitoring across these settings is difficult.

  • Continuous profiling across dispersed units from one view
  • Automatic alerts when low-use outlets develop risk conditions
  • Cellular and LoRaWAN telemetry for settings with limited infrastructure
  • Exportable evidence for each scheme on demand
Registered Managers

A live picture, not a clipboard.

Registered managers are accountable for resident safety and CQC compliance while juggling care delivery. A live monitoring picture replaces uncertainty between rounds with continuous assurance.

  • Real-time visibility of water temperatures across the home
  • Immediate notification when a flush is missed or a threshold breached
  • Tamper-evident records that back up the written scheme of control
  • On-demand reports for CQC, insurers, and the responsible person
Open, interoperable systems. No lock-in. Engineered for operational environments.

Questions & Answers

Legionella monitoring for care homes, answered

How does automated monitoring support our CQC and HSE L8 duty of care?
AQUAIOT records temperatures continuously at tanks, loops, thermostatic mixing valves, and sentinel outlets, and checks them against HSE L8 guidance. It strengthens the duty holder’s written scheme of control with a complete, tamper-evident record that supports CQC inspection, while responsibility for the overall control scheme remains with the provider.
Can it monitor thermostatic mixing valves for both scald risk and Legionella?
Yes. AQUAIOT profiles temperatures at thermostatic mixing valves and sentinel outlets continuously, so you have a record of both safe outlet temperatures for frail residents and hot water temperatures relevant to Legionella control, with alerts when readings drift outside guidance.
What happens to little-used rooms and empty beds?
Continuous profiling catches stagnation and temperature drift at low-use outlets and vacant rooms between manual rounds, and sends immediate SMS, email, or app alerts when readings move into risk zones or a flush is missed.
Can sensors be fitted without disrupting the home?
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 home.
How quickly can we produce records for a CQC inspection?
Every reading and alert is held in tamper-evident logs with secure timestamps and is exportable on demand, so producing evidence for a CQC inspection or insurer takes minutes rather than days of compiling paper logbooks.
Is it suitable for a group of homes as well as a single home?
Yes. AQUAIOT scales from a single home to a multi-site group, with continuous monitoring across every property visible from one dashboard and role-based access for managers and group compliance leads.
