Leak detection in London
Water leak detection across London stock.
London holds some of the most valuable and most listed property in the country, much of it stacked over basements and lower-ground floors where escaping water collects unseen. AQUAIOT senses moisture and abnormal flow across your London buildings, then isolates the supply automatically before a slow leak reaches a vault, a riser or a flat below.

Basements and lower-ground floors flood first.In so much London stock the water collects below ground where no one is standing, so a slow leak runs for hours before it is found.
Listed fabric is costly to put right.Water in a listed or period building does not allow a quick strip-out, and reinstating original plaster and joinery can dwarf the plumbing repair.
A riser leak reaches many flats.In a high-rise block water that escapes at the top tracks down the riser through floor after floor before anyone reports it.
It is the costliest claim on the book.Insurers pay around one point eight million pounds per day in escape-of-water claims according to the ABI, and London underwriters expect active monitoring on the buildings most at risk.
The AQUAIOT SolutionRequest a Consultation
Detection built for dense, high-value London buildings
In central London a leak rarely stays in one place. Water tracks down through high-rise risers, soaks into listed fabric that cannot simply be stripped out, and pools in basements and lower-ground floors where nobody looks until the damage is done. AQUAIOT puts moisture sensors at the points water gathers, reads flow on the incoming main across the Thames Water region for the slow weep a porter never reports, and closes an auto-isolation valve the moment a threshold is crossed. Every reading is logged for the freeholder, the managing agent and the insurer.
Sensing in basements and risers. Point and rope moisture sensors in lower-ground floors, plant rooms and high-rise risers, plus inline flow analytics on the main to catch the slow leak between inspections.
Isolation that protects listed fabric. Auto-isolation valves close the supply on a moisture or abnormal-flow trigger, cutting the water before it reaches plaster, panelling and finishes that are costly to restore.
Evidence for high-value cover. Every alert, reading and shut-off event is timestamped and exportable, giving London underwriters a defensible record of active water management.

How It Works
Three steps from first drop to evidence
Step 01
Detect
AQUAIOT moisture, flow and freeze sensors are deployed at the points water escapes. Every reading is timestamped and logged to the cloud over secure cellular or LoRaWAN telemetry.
Step 02
Alert and isolate
When moisture is sensed or flow goes abnormal, AQUAIOT raises an immediate alert by SMS, email and app, and closes the auto-isolation valve so water is stopped before damage spreads.
Step 03
Record
Every reading, alert and isolation event is captured in exportable, timestamped logs that integrate with CAFM and BMS, so evidence for insurers is ready on demand.
Capabilities
Everything a leak detection programme needs
Purpose-built for estates, facilities and risk teams protecting buildings against escape of water across single or multiple sites.
Moisture sensing at the risk points
Point, rope and tray sensors detect water at first contact under appliances, in plant rooms, risers and tank rooms, before it spreads.
Inline flow analytics
Continuous flow monitoring on the incoming main learns normal use and flags the slow weep or continuous draw a manual check never sees.
Freeze protection
Temperature monitoring on exposed and loft pipework warns before a freeze leads to a burst, so action can be taken in time.
Automatic shut-off
Auto-isolation valves close the supply the moment a moisture or abnormal-flow threshold is crossed, with manual remote override for the duty holder.
Multi-channel alerts with escalation
SMS, email and app alerts with role-based routing, so the right person responds day or night, on a single site or across a portfolio.
Open integration, no lock-in
Connects to BMS, CAFM and SCADA via RS485/Modbus or REST API, with audit-ready exportable records for insurers and owners.

Questions & Answers
Common questions
Does AQUAIOT cover central London buildings with deep basements?
Yes. Moisture sensors sit in basements, lower-ground floors and plant rooms where London water collects, and inline flow analytics watch the incoming main for the slow weep a porter will not see.
Can it protect a listed or period building?
Yes. Sensing and clamp-on ultrasonic flow monitoring are non-invasive and retrofit-friendly, so a listed London building gains early detection and automatic shut-off without cutting into pipes or fabric.
How does it handle a high-rise riser leak?
Moisture sensors at the riser and abnormal-flow logic on the supply catch a leak early, and an auto-isolation valve closes the water before it tracks down through the flats below.
Will it help with insurance on a high-value London property?
Active monitoring with automatic shut-off is recognised evidence of proactive risk management, with up to around eight percent premium reduction potential, though your insurer sets the terms.
Does it suit the Thames Water region supply?
Yes. The system reads flow on the incoming main whatever the London supplier, sending real-time alerts by SMS, email and app the moment a threshold is crossed.
