Social Housing Legionella Monitoring in London

London social housing,
watched continuously.
Including the empty homes.

London housing associations and councils carry a statutory landlord duty across thousands of dispersed homes, and void flats stagnate fastest of all. AQUAIOT fits wireless temperature sensors at communal tanks, calorifiers, loops, and sentinel taps, checking readings against HSE L8 and HSG274 Part 2 around the clock.

The AQUAIOT Solution

Continuous L8 cover
for London’s
dispersed housing stock.

London social housing rarely sits in one block. AQUAIOT brings communal systems across towers, low-rise estates, and scattered street properties onto one dashboard, so your landlord compliance record stays current across every site without sending an operative to each address.

Real-time temperature profiling at communal tanks, loops, and sentinel outlets across London estates, with extra attention on void and low-use homes.
Threshold alerts against HSE L8 guidance, immediate SMS, email, and app notification the moment a reading drifts into a risk zone or a flush is missed in a vacant property.
Tamper-evident, exportable audit trails, with API, BMS, and CAFM integration so your landlord compliance evidence is ready on demand.

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 London social housing, answered

Do you cover social housing across London?
Yes. AQUAIOT engineers survey, install, and commission across Greater London and the surrounding home counties, with UK-wide coverage beyond that. We work with housing associations and councils on both high-rise blocks and dispersed street properties.
How does this help with our statutory landlord duty?
As a social landlord you hold a duty of care to control Legionella risk across your stock. AQUAIOT records communal temperatures continuously and alerts when readings move outside HSE L8 guidance, strengthening your written scheme of control. Legal responsibility for the scheme stays with your duty holder.
Can you monitor void and low-use properties?
Yes, and this is where continuous monitoring earns its place. Empty homes stagnate quickly and manual flushing is easy to miss. Sensors at the relevant outlets detect rising temperatures and missed flushes in vacant London flats, so the void team can act before a property is re-let.
Can sensors be fitted without disturbing tenants?
Yes. Our sensors retrofit into live communal systems with no pipe cutting and no shutdown, so occupied London blocks keep running normally. Most work happens at communal plant rather than inside individual tenanted homes.
Does it integrate with our housing management or CAFM system?
Yes. AQUAIOT connects to SCADA, AIMS, CAFM, and BMS platforms over RS485/Modbus or REST API, so London housing teams keep one source of truth across their estate without vendor lock-in.
