Leaks Caught Fast with Smart Shut-off Valves

Prevent Water Damage

Lower Insurance Premiums

62% of construction sites will report water damages

Large losses from the escape of water on construction sites are now more frequent than fire-related incidents. Higher premiums, higher deductibles and loss of cover are increasingly common for sites with no protection.

£193m per year

Total Escape of Water claims for commercial insurance.

A leak occurs every 10 minutes!

£55,000 average claim

due to water damages on construction sites, but can exceed £1,000,000

5.6x lower chance of claiming with tech

An average site has 62% chance of claiming. With smart leak detection, this lowers to only 11%.

We are here to help you adhere to CIREG Best Practice

Management – nominate a Responsible Person to be overseen by the Principal Contractor.

Design Considerations – planned installation of automatic flow monitoring and automatic shutoff devices in the operational building to improve the availability of insurance.

Installation Standards – compliance with the Water Supply (Water Fittings) Regulations 1999, BS EN 806, BESA Good Practice Guides, CIBSE standards, and CIPHE plumbing engineering design guide.

Quality Management – Only qualified, competent plumbing engineers should be permitted to work on water distribution systems with at least a Level 3 NVQ, CSCS card, and affiliation to CIPHE (or similar).

Testing and Commissioning Standards

Emergency Response – detailing clear and simple procedures to isolate the water supply and remove the risk.

Mitigation – installing Automatic Flow Monitoring with Smart Shut-off Valves such as LeakNet.

Complete water management with intelligence which immediately shuts the water off to prevent damages.

Rapidly Detect Leaks

Learns normal water usage over time and shuts off the supply if flow becomes abnormal.

Autonomous operation

Monitor and control water anywhere, temporary supplies, irrigation, booster pump sets… Isolate the supply outside working hours and weekends when the building is unattended, and remain fully operable after handover.

Any pipe size

Split complex buildings by floor or zone to easily identify leaks and isolate individual or multiple areas at once.

Grouping functionality

Alerts from multiple systems can be sent to multiple appointed persons by email, SMS, as well as to a BMS.

Many to Many Alerts

Realtime monitoring to quickly find leaks, battery backup, WiFi/2G/4G/GSM/cellular connection, sprinkler override…

And much, much more…

Why choose Quensus?

We provide solutions, not products

Effective water management and leak detection is all about service, not a product. Without a good plan, installation, commissioning, programming, and training, the best product in the world will not help.

Using our proprietary online software as the backbone of our service allows us to provide all the necessary components of a complete system for you, including dedicated customer support, continuous CPD training, bespoke Standard Operating Procedures (SOP), configuration of alert settings, consultancy for consumption data and leakage reporting, dedicated technical support, diagnostics of wireless equipment and signal quality, and servicing requirements.

We provide value for money

Our systems are the most versatile on the market. Virtually any mechanical system can be installed or retrofitted, and we also supply contact based leak detection as well as flow based solutions.

When designing the best system for your site, you must remember the larger the pipe, the more difficult it is to analyse usage patterns and detect leaks. We will work with you to design the most effective system with the best value.

We work with a number of technologies and are always innovating such as our new wireless splash sensors with a 15 year battery life. We will always find a solution that is reliable and affordable.

We provide a great service

This is not just another Waterguard or Floodcheck or Aquaguard or Autostopcock or Leaksafe or Aquilar…

Our leak alerts are dynamic, meaning fewer false detections. Other leak detection systems work on the principle of time only. LeakNet works off time, volume, time of day, day of week, and more, using machine learning to automatically set parameters for maximum protection with minimum false alerts.

And because construction sites are often unpredictable, and you will probably have no time to deal with leaks, we offer a leasing option providing you with ongoing support for as long as is required. We call this “Water Management as a Service”.

Water Management as a Service

Instead of simply providing hardware, we will work with the Responsible Person(s) and your insurance provider to ensure the appropriate system is specified, installed correctly, provide commissioning certificates, and give training to all nominated duty holders.

Installation CPD Training

On-site and/or remote training to contractors for the installation and operation.


Each multi-residential/commercial project is managed by a dedicated engineer providing technical support and commissioning with commissioning certificates available at no extra cost.


Leak systems can be migrated between phases and to the final occupant/property manager/concierge for which we provide further CPD training and bespoke Standard Operating Procedures (SOP).
