Jump to: How can Quensus Can Help Prevent Future Leaks?
High-value, high-rise developments are especially vulnerable to escape-of-water (EoW) incidents. Even one undetected leak can escalate in multi-million-pound repair costs as water spreads through complex plumbing and interconnected floors.
With repairs, leaks often force resident relocations, resulting in propriety owner, landlord or insurer expenses to mitigate temporary accommodation, removals, storage, and lost rental income. As leaks are 50% more likely to re-occur after 1 claim, and 80% after a 2nd , building owners may also face rising insurance premiums or refusal of cover.
Beyond the financial cost, leaks can also cause serious reputational damage. Issues like mould, structural damage, and health risks for residents can quickly escalate into legal liabilities, particularly when claims involve construction defects or habitability.
Liquidated and Ascertained Damages (LADs) are another critical financial risk as contractual penalties often triggered by project delays or defects like leaks and water ingress.
Insurers are placing increasing pressure on developers to mitigate risk, especially in high-rise and high-value developments.
Pre-binding risk mitigation is now expected, with leak detection systems required in critical areas such as riser cupboards and plant rooms. Insurers also demand strict maintenance and inspection regimes, with documented system and trained personnel.
The following trends are reshaping the insurance landscape:
No need for manual leak inspections. Monitor leak status via the FlowReporter app and receive instant notifications of suspected leaks.
Our AI-powered multi-zone monitoring learns your building’s normal water usage, detects anomalies, and eliminates false alarms.
Upon detecting a leak, Quensus automatically closes the relevant valve and pushes notifications via email, SMS, and app to residents, concierge, and building managers. Integration with any BMS ensures a unified response.
Install sensor nodes in high-risk areas (under sinks, behind appliances, near soil stacks) for instant local alerts—saving hundreds in wasted water and remediation costs.
Quensus enhances operational reliability and resident satisfaction through real-time insights, automated controls, and rapid leak response.
Point-of-leak sensors monitor high-risk areas and connect seamlessly to the FlowReporter app, giving designated users real-time access to personalised water usage insights, environmental conditions, and smart alerts. As the system owner, you can decide who can access this data, whether this is the tenant, a designated person or team.
Designed for premium developments, Quensus integrates natively with building management systems, enabling automatic water shutoff, HVAC overrides, and even fire-sprinkler overrides without tenant disruption

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.
