LeakNet is an intelligent Smart Water Management System that continuously monitors water usage, identifies abnormal behaviour, and can automatically isolate supply where required to prevent damage, reduce risk, and improve operational visibility across commercial buildings, residential accommodation, high-risk assets, and multi-site portfolios.
Unlike basic shut-off valves or standalone leak alarms, LeakNet is built as a prevention platform. It monitors water behaviour continuously, highlights abnormal consumption early, and helps contain incidents before they escalate, while providing insurers, engineers, and facilities teams with the visibility, reporting, and control needed to manage water risk proactively.
Escape-of-water incidents are one of the most costly and disruptive risks facing buildings. Even a small hidden leak can lead to major reinstatement costs, unplanned downtime, asset loss, tenant disruption, reputational impact, and long-term insurance consequences.
At the same time, building owners and operators face increasing pressure to:
A Smart Water Management System brings these together in one platform: prevention, compliance, sustainability, and operational resilience.
An automatic water shut-off system monitors water flow in real time and isolates supply when unusual activity is detected. That could be a burst pipe, a long-running trickle leak, or a failed fixture.
Traditional shut-off devices are often mechanical or threshold-based. They can be useful, but they are limited. Fixed limits do not reflect real building behaviour, which can lead to missed risk scenarios or unnecessary disruption.
LeakNet takes a different approach.
LeakNet uses flow analytics and behaviour modelling via FlowReporter to understand how water is used across your building. Over time, it learns what “normal” looks like by zone, by occupancy pattern, and by operating schedule.
When behaviour changes, LeakNet can:
Instead of reacting to water damage, you prevent escalation before it starts.
LeakNet continuously monitors live water-flow data through IoT-enabled metering and zone-based design. As the system learns your building’s patterns, it becomes increasingly effective at spotting abnormal behaviour.
LeakNet can detect:
Where configured, the system automatically isolates supply to contain incidents. At the same time, your team receives clear alerts and reporting so action is fast, informed, and consistent.
Basic shut-off valves operate using fixed limits. If water exceeds a set volume, they shut off. This can work in simple scenarios, but it can also miss real-world risk and create unnecessary disruption.
LeakNet is behaviour-led and prevention-first. That means:
Mechanical devices react. LeakNet understands and intervenes.
LeakNet supports compliance and risk governance by combining continuous monitoring, actionable alerts, and documented control.
It is particularly relevant where water risk management and reporting are required or strongly beneficial, including:
The result is technology that does not simply “tick the box”, but delivers measurable risk reduction and operational assurance.
LeakNet is particularly effective in high-risk, high-value, and multi-occupancy environments, including:
Whether installed into new builds or retrofitted into live environments, LeakNet provides visibility and control across complex water networks without unnecessary disruption.
Organisations using LeakNet typically see:
Most importantly, teams gain confidence that water risk is being managed intelligently, not reactively.
LeakNet is operated through FlowReporter, Quensus’ cloud-based water intelligence platform that connects LeakNet devices with your wider building infrastructure. This means water risk is managed as part of your overall operational strategy, not as an isolated system.
FlowReporter brings together live data, alerts, reporting, and control into one central environment, supporting integration with BMS, IoT ecosystems, and multi-site property portfolios.
Through FlowReporter, teams gain:
Rather than reacting to incidents after damage occurs, FlowReporter provides the visibility, evidence, and operational control needed to manage water risk proactively.

LeakNet can be deployed during construction, refurbishment, or into existing occupied buildings. Whether incorporated at design stage or introduced to an operational asset, the focus is the same: effective risk control with minimal disruption and a system that delivers measurable value from day one.
For new build projects, LeakNet can be designed into the water infrastructure early, allowing zoning, monitoring points, and isolation strategies to align with building layout, risk profile, and insurer expectations. This typically simplifies installation, improves visibility across the network, and ensures compliance requirements are considered from the outset.
For refurbishment or retrofit projects, systems are usually deployed around key access points such as incoming mains, plant rooms, risers, boosted water systems, and higher-risk zones. Installations are planned carefully to minimise disruption to occupants while still delivering meaningful monitoring and control where it matters most.
Quensus supports contractors, consultants, and FM teams throughout the process with:
Up to 7 credits for reducing water usage per person per day compared against a baseline performance. For example, use water-saving WCs, tap aerators, low-flow showers, waterless urinals, and greywater/rainwater for recycling non-potable water.

By promptly identifying and addressing leaks, buildings can significantly reduce water wastage, contributing to a more sustainable water footprint. 1 credit has traditionally been given for a leak detection system that can detect a major water leak on the mains water supply within the building and/or between the building and the utilities water meter.
Our advanced leak detection technology, including smart metering and real-time monitoring, can quickly identify and locate leaks, enabling prompt repairs and minimising water wastage, potentially enabling you to achieve the full 4 credits after a complete calendar year.
Up to 4 credits for proactive measures to prevent leaks. Proper installation and maintenance of flow control devices, whether in sanitary fittings or larger residential complexes, are essential for minimising water loss and ensuring the longevity of plumbing systems.
Our LeakNet system goes beyond traditional leak prevention methods. With AI-powered monitoring, real-time alerts, and automatic shut-off capabilities, LeakNet actively identifies and stops leaks before they cause significant damage or water wastage. This proactive approach aligns perfectly with the BREEAM focus on minimising water loss and ensuring the longevity of plumbing systems.
Up to 4 credits can be awarded depending on the extent and effectiveness of the isolation valve strategy within the building's water supply system, which allows controlled shut-off of specific sections of the water supply, enabling targeted maintenance or repairs without disrupting the entire system. 1 credit has traditionally been given for installing a flow control device to each WC area/facility so that water is only supplied when needed.
Our smart shut-off valves seamlessly integrate into any plumbing system, providing the isolation capabilities necessary for targeted maintenance and repairs.
This not only meets the traditional BREEAM requirement for isolation valves but also enhances it with intelligent control and automation.
By enabling quick and precise shut-off of specific sections, LeakNet minimises disruption and water wastage during maintenance activities, maximising the potential for achieving up to 4 credits.
The automatic shut-off functionality also serves as an innovative flow control device, securing an additional credit for controlling water supply to WC areas.
Up to 4 credits for using alternative water sources and efficient water-using technologies. Rainwater harvesting, greywater recycling, and the use of water-efficient fixtures are examples of strategies that can substantially decrease reliance on mains water supply.

A comprehensive water strategy goes beyond individual measures by establishing a holistic approach to water management. It includes regular maintenance of water systems, water efficiency, water reuse, and leak detection. The strategy should also include a plan for monitoring and reporting water consumption ensuring optimal performance and longevity, as well as promoting awareness and behavioral changes among building occupants to foster a water-conscious culture.
Up to 8 credits are available depending on the comprehensiveness of the water strategy and the inclusion of specific elements such as:
A proactive maintenance policy for installed water systems
Targets for reducing water consumption
A plan for monitoring and reporting water consumption
A plan for engaging building occupants in water conservation efforts
Our holistic approach to water management and expertise in water efficiency, reuse, and leak detection can help building owners develop and implement comprehensive water strategies that achieve long-term sustainability and cost savings.
Every building’s risk profile and budget differ. Unlike one-size-fits-all systems, Quensus engineers a bespoke leak-detection solution around your insurer’s requirements and cost constraints - saving you thousands in wasted water and premiums. There is an unlimited number of options, but we have simplified leak prevention into our four main tiers:
A combination of bronze, silver and gold will provide the most effective leak prevention system available.
Automatic Flow Monitoring with Smart Shutoff Valves on the boosted supply to each unit/apartment. The most effective solution post-handover over the lifetime of the building.
Automatic Flow Monitoring with Smart Shutoff Valves on the boosted supply to each floor (or each riser if plumbing is vertically fed). Ideal during construction because each floor can be isolated individually.
The absolute minimum you should be looking for is Automatic Flow Monitoring on the Mains Cold Water System and Boosted Cold Water System for the whole building. This is covered in the BREEAM WAT03 standard.

We’ve compiled the top FAQs for quick answers - Read FAQ.
What is a Smart Water Management System in a building context?
It is a platform that monitors water use across the supply, identifies abnormal behaviour early, and provides reporting and control so water risk can be managed like any other building system. The goal is measurable visibility, faster response, and reduced incident severity across the whole network.
What makes LeakNet a smart water management system rather than a leak alarm?
Leak alarms usually trigger when water is already present at a point. LeakNet monitors water behaviour across the system, builds a normal usage profile by zone and time, and flags abnormal patterns early.
Can LeakNet help reduce water bills as well as prevent damage?
Yes. Continuous monitoring can highlight long-running wastage, out-of-hours flow, and inefficient consumption that often goes unnoticed. That visibility helps teams investigate issues earlier and improve operational efficiency.
What does “zone-based monitoring” mean and why does it matter?
Zone-based monitoring breaks a building’s water network into logical areas (for example floors, risers, landlord supplies, plant areas, or high-risk zones). It improves visibility on where abnormal usage is occurring and allows isolation to be targeted, reducing disruption.
Does LeakNet only shut off water when there is a burst?
No. It can detect a range of abnormal behaviour including continuous low-level leaks, unexpected flow during closed periods, fixture failures, and rapid loss events. Shut-off is optional and can be configured to suit risk level and operational needs.
How do you avoid unnecessary shut-offs in busy buildings?
LeakNet uses behaviour-led thresholds aligned to your building’s usage patterns and operating schedule, rather than blunt fixed limits. Shut-off can also be limited to priority zones, with alert-only behaviour in areas where automatic isolation would be disruptive.
Can LeakNet be managed across multiple sites?
Yes. LeakNet is designed for multi-site portfolios with central visibility and consistent reporting. This allows risk and FM teams to standardise water risk governance and track performance across an estate.
What reporting does LeakNet provide and who is it for?
LeakNet provides event logs and reporting designed for facilities teams, engineers, and risk stakeholders. Reporting helps demonstrate monitoring coverage, incident history, response actions, and improvements over time, which supports compliance and insurer discussions.
Does LeakNet support BREEAM WAT03 and similar standards?
LeakNet supports compliance objectives where monitoring, mitigation, and evidence of water risk management are required or strongly beneficial. For BREEAM WAT03 specifically, continuous monitoring, alerting, targeted mitigation, and audit-ready reporting help demonstrate proactive control.
Can LeakNet integrate with a BMS or existing building platforms?
Yes. LeakNet can integrate into wider building operations so water risk events sit alongside other building systems. Integration options depend on the existing infrastructure and the level of visibility and control required.
Can LeakNet be retrofitted into occupied buildings?
Yes. Retrofit projects are typically designed around access points such as incoming mains, plant rooms, risers, and priority zones, so disruption is minimised while control is improved where it matters most.
What is the typical process to specify and deploy a smart water management system?
Most projects start with a risk-led review and a proposed zoning and control strategy. This is followed by installation, commissioning, and agreement of response procedures so monitoring, alerts, and isolation are operationally effective from day one.
