Water leaks are one of the most costly and disruptive risks facing residential and commercial buildings. From burst pipes and failed appliances to slow, hidden leaks, even minor incidents can escalate quickly, leading to structural damage, tenant disruption, operational downtime, and increased insurance exposure. Reports that escape of water is the number one insurance claim type in UK households, costing insurers £2.5 million every single day. (InsurerTimes)
In many buildings, leak detection is introduced only after water damage has already occurred. While this can help identify the source of a problem, it does little to reduce the risk of future incidents or limit long-term exposure.
Quensus helps building owners, operators, insurers, and developers move beyond reactive leak detection and into intelligent, automated leak prevention. Our systems are designed to identify abnormal water behaviour early and intervene before a leak becomes a claim, a repair, or a business interruption.
Leak detection is the process of locating and identifying a water leak in your property - whether it’s visible or hidden.
Traditional leak detection:
While effective for immediate problems, traditional leak detection is reactive, meaning the damage has often already started.
Quensus takes leak detection to the next level. Using smart monitoring technology, we can detect unusual water use, alert you instantly, and even automatically shut off the water supply before major damage occurs.
This proactive approach protects your property, saves money, and prevents disruptions.
Quensus provides solutions for any property where water damage is a risk, including:
Modern buildings require a different approach. Instead of waiting for leaks to occur, intelligent systems can continuously monitor water flow, identify abnormal patterns, and intervene before damage happens.
This is where leak detection evolves into leak prevention.
Quensus systems monitor water usage in real time, analysing flow behaviour across individual zones, buildings, or entire portfolios. When abnormal activity is detected, such as continuous flow, unexpected spikes, or usage outside defined thresholds, the system alerts stakeholders immediately and can automatically isolate the water supply if required.
The outcome is not faster response after failure, but fewer failures overall.
Smart leak detection is not emergency response and it is not on-site leak finding. Quensus does not provide emergency leak repair or reactive call-out services.
Instead, smart leak detection means:
By identifying risk conditions rather than visible damage, intelligent systems remove reliance on reactive intervention and significantly reduce the likelihood of major leak events.
LeakNet is Quensus’s intelligent water monitoring and leak prevention platform. It is designed to replace reactive leak detection with proactive risk control.
LeakNet continuously analyses water flow data to understand what normal usage looks like for each building. When anomalies are detected, the system responds in real time.
LeakNet can:
Rather than reacting after damage occurs, LeakNet helps eliminate repeat incidents and reduce long-term exposure.
Escape of water remains one of the most frequent and costly insurance claims across the built environment. Claims often result in increased premiums, higher excesses, and tighter underwriting conditions.
Insurers increasingly favour buildings that demonstrate proactive risk management rather than reactive response.
By preventing leaks before they escalate, LeakNet helps:
That is why Quensus works in partnership with Aviva, aligning prevention-led technology with the way leading insurers assess and manage risk.
For many organisations, the real value of prevention lies beyond repair savings, in avoided claims and long-term insurance stability. If that sounds attractive, get an instant quote today.
LeakNet is used across environments where water damage presents a material risk, including:
Each system is configured to reflect the building’s layout, usage patterns, and compliance requirements.
A single serious leak can result in repair costs, tenant displacement, business interruption, reputational damage, and long-term insurance impact.
LeakNet addresses the root cause rather than the aftermath.
Clients typically see value through:
In many cases, preventing one major incident offsets the cost of implementation.
If you are searching for leak detection, it is likely because water risk is already a concern.
The real question is not how quickly a leak can be found after it occurs, but how reliably it can be prevented from happening again.
Quensus helps organisations move beyond reactive detection and into intelligent, automated leak prevention.

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.
Our expertise in smart water metering and data analytics allows us to monitor and analyse water consumption patterns, providing valuable insights to identify water-saving opportunities and track progress towards reduction targets.
Installing our device on the main meter earns you 4 points.
Sub-metering building areas consuming 10% or more of the building's total water demand, or metering multi-tenant buildings per tenanted area, achieves an additional 2 credits.
Up to 4 credits (each) are available based on the water efficiency of the following assets to reduce overall water consumption in the building:
WAT02 - Water-efficient equipment: toilets
WAT03 - Water-efficient equipment: urinals
WAT04 - Water-efficient equipment: hand washing basins
WAT05 - Water-efficient equipment: showers
WAT06 - Water-efficient equipment: white goods
Our experience in specifying and installing water-efficient fixtures can help building owners select and implement the most appropriate solutions to achieve significant water savings.
Up to 4 credits for installing a robust leak detection system, which plays a vital role in conserving water resources. 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, maximizing 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.
While we don't directly address alternative water sources, LeakNet's ability to dramatically reduce water wastage through automatic shutoff and leak prevention contributes to lowering mains water consumption.
By minimising unnecessary water loss, LeakNet supports the overarching goal of WAT10, contributing to achieving the maximum credits available.
Up to 4 credits for accurate monitoring and reporting of water consumption data, which is fundamental to effective water management. By tracking consumption patterns, building owners and operators can identify areas for improvement and implement targeted water-saving measures.

Earn 1 extra credit when you report on it internally, and another credit if you publish this information in an annual report.
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 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.
