If you’re considering recommending our solutions, you’ll find they align with insurer requirements and proven risk-reduction outcomes.
Choosing Quensus means more than great products. Even the best system won’t help unless it’s installed and used correctly. That’s why we go beyond supplying technology and help clients reduce incidents and get faster resolutions.
Escape of Water mitigation means taking proactive steps to prevent, detect, and minimise water damage before it leads to costly insurance claims. For insurers, this reduces claim frequency and severity, improves underwriting accuracy, and ensures compliance with UK standards such as the JCOP.
UK insurers view Active Automatic Flow Monitoring and Shutoff (AAFMS) systems as essential for risk management, often offering preferential rates and better terms to policyholders who install them.
AAFMS solutions comply with key industry standards, including the Joint Code of Practice (JCOP) for Escape of Water Prevention and Management on Construction Sites, often cited in insurer underwriting manuals.
When a leak does occur, AFMS devices provide remote telemetry, giving insurers and loss adjusters real-time access to flow data and shutoff records. This often eliminates the need for immediate site visits, reduces damage from leak escalation, and cuts down on alternative accommodation, business interruption costs and any other associated cost. he result is faster settlements, lower adjuster fees, and improved customer satisfaction.
Advanced AAFMS analytics also help insurers:
At Quensus we go beyond leak detection and focus on the ROI of leak prevention. Unlike reactive approaches, our proactive solutions help insurers and their clients avoid the multi-billion-pound costs of water damage incidents

Already an official Specialist Partner of Aviva Risk Management Solutions, Quensus strives to work with other insurers to provide benefits for both providers and policyholders.
Escape of water damage is one of the most common types of domestic property damage claims, with average insurer daily pay-out of £1.8 million.
In construction 2/3 (66%) of sites suffer Escape of Water losses, averaging £300k in just deductibles across just three sites.
By installing Quensus Automatic Flow Monitoring and Smart Shut-off Valves, that risk drops to just 1 in 10 sites, turning potential six-figure losses into savings through early detection, fast shutoff, and an over 80% claim reduction.
