Homeowners

Your home, protected even when you’re not there

A burst pipe in an empty home can lose thousands of litres before anyone notices. Quensus watches consumption day and night, alerts you the moment it detects something unusual, and shuts off the water automatically if the leak is significant.

  • Peace of mind when you’re away. Second homes, holiday lets or months spent outside Spain: the system watches around the clock.
  • Automatic, remote shut-off. The valve closes itself for a significant leak, and you can open or close it yourself from the app.
  • Invisible leaks brought to light. A running toilet cistern can cost around €1,000 a year without you ever noticing.
  • Proof if your bill spikes. A dated flow record shows exactly when a leak started — useful evidence for your water company or your insurer.

Private home with spa and pool (insured by Aviva)

A major leak caught and shut off in time

A private homeowner was carrying out a full renovation of their property, with a spa, pool and server room. On the recommendation of their insurer, Aviva, four independent LeakNet Gen2 units were installed at the property (mains, boosted supply, hot water and pool), plus leak-detection cable under the hot water cylinders. Within days the system caught a minor leak in a pool valve. A month later, it shut the water off automatically when it detected a burst fitting in the plant room right next to the server room.

Portfolios & communities

The water risk across your whole portfolio, on one screen

Water damage is the most frequent claim type in real estate. Quensus turns that invisible risk into data you can measure and manage, asset by asset and unit by unit.

  • Alerts and automatic shut-off on every asset, with a consolidated portfolio view in FlowReporter.
  • A stronger position with insurers and lenders, backed by verifiable documentation of proactive risk management.
  • Traceable consumption data for GRESB, BREEAM In-Use and investor reporting.
  • For property managers (administradores de fincas): monitoring of communal supply lines and risers, with alerts to the manager and the president.
  • Phased rollout. Pilot on one or two assets, then extend across the portfolio once the data justifies it.

High-rise residential developer (BTR operator)

From claims in the millions to none over £10,000

After a first year with multi-million-pound water-damage claims, the developer’s insurer raised the excess on every project. A 1" flow meter and a motorised valve were fitted in every home, plus a 2" meter per floor for communal-area leaks, in two already-built towers.

Retail & shopping centres

A leak can’t close an aisle during opening hours

Many units, heavily used toilets, shared infrastructure, and hours with no one in the building. Quensus detects abnormal overnight flow and bursts before opening, and shows exactly where the water is going.

  • Out-of-hours detection: nights, Sundays and public holidays, with automatic shut-off.
  • Zone- or unit-level metering to pinpoint abnormal consumption and support recharging costs to tenants.
  • Toilets under control: cisterns that won’t stop running, urinals and taps that use more than they should.
  • Water-contact sensors in plant rooms, technical cupboards and risers.

Motorway services operator

An investment plan built on real data, toilet by toilet

A motorway services operator with 28 sites didn’t know which toilets were wasting water or which refurbishments would pay off. LeakNet, LeakNet LP loggers and FlowReporter measured every toilet block and built a business case for each repair.

Industry, logistics & construction

Control the water in your plant and your site the way you control energy

In a warehouse, a leak means lost water, stopped production and damaged stock. On a construction site, it can destroy weeks of work overnight and delay handover.

Industry & logistics

  • Abnormal consumption picked up across shifts and during shutdowns.
  • Mobile-connected loggers for remote or off-network meters.
  • Automatic shut-off to protect warehouses, electrical rooms and sensitive areas.
  • Traceable data for water-efficiency and carbon-footprint targets.

Construction & development

  • Monitoring during the highest-risk phases: pressure testing, fit-out, nights and weekends.
  • SiteNet, the construction-site version: IP66 enclosure, backup battery and 4G connection.
  • Fewer claims on the contractors’ all-risks policy and less risk of delays.
  • Hand over a building with water monitoring already in place from day one.

Distribution warehouse (industry & logistics)

Two hidden leaks, £9,500 a year

A large logistics warehouse with unusually high water bills installed LeakNet Gen2 and FlowReporter. The system located a faulty cistern losing 6,000 litres a day and a second leak losing 4,800 litres a day.

Why Spain

Why water intelligence matters in Spain

Spain faces a combination of water scarcity, ageing building infrastructure and growing pressure on commercial property operators to demonstrate responsible resource management.

  • Drought and water scarcity. Prolonged drought periods and seasonal water restrictions make efficient water use a strategic necessity for commercial property operators across Spain.
  • Hidden leaks go undetected. Leaks in commercial buildings and residential communities can run for months without detection, generating significant waste and causing structural damage that accumulates quietly.
  • Lack of real-time visibility. Most buildings rely on quarterly utility bills and reactive maintenance. Continuous monitoring reveals what billing cycles cannot — flow anomalies, after-hours consumption and gradual waste.
  • Regulatory and market pressure. Tenants, lenders and investors increasingly expect documented evidence of responsible water use. The pressure to demonstrate efficiency is growing across all segments of commercial real estate.
  • Buildings without constant supervision. Office buildings, schools, shopping centres and community facilities are particularly vulnerable during unattended periods. Intelligent monitoring provides continuous coverage when no one is physically present.

Try a real-world leak

In Rojales the sewer ordinance lets the town council reduce charges for undetected leaks in the customer’s own pipes, on request and when the leak is not caused by negligence. A dated flow record shows when a leak began.

ESG & BREEAM

Water data that stands up to an audit

FlowReporter logs every asset’s consumption continuously and with a timestamp, ready to feed into your GRESB reporting or a BREEAM In-Use audit.

  • Verifiable consumption data for sustainability and GRESB reporting
  • Support for BREEAM In-Use assessments and green-building programmes
  • Portfolio-wide visibility of water risk
  • Operational documentation for lenders and insurers
  • Measured, not estimated, water and CO₂ savings

AquaCe supports water-efficiency strategies and improves operational documentation. It does not guarantee BREEAM credits or compliance with any specific standard; formal certification requires a licensed BREEAM assessor.

Frequently asked questions

What people usually ask us

Who installs the equipment?
Your own trusted plumber or maintenance team. Quensus hardware is designed for straightforward installation by any qualified professional. We advise you, ship the equipment with full documentation, and answer questions remotely during installation.
Is it suitable for a residential community (comunidad de propietarios) with shared water infrastructure?
Yes. Shared water infrastructure in residential communities is one of the relevant use cases for Quensus. The system can help managers gain better visibility of communal supply lines and catch abnormal behaviour before incidents escalate.
Does it work for a home I only use a few months a year?
It’s one of the cases where it makes the most difference. The system watches flow 24 hours a day, alerts you to any unusual consumption, and shuts the valve automatically if it detects a significant leak. You can close or open the water remotely from the app.
Do you need to cut the water supply during installation?
A brief interruption is usually enough while the plumber connects the flow meter and valve to the main supply. Duration depends on the property and is planned in advance to minimise disruption.
What happens if the internet connection drops?
Remote alerts and the dashboard need connectivity. Depending on the configuration, some local protection functions keep operating on pre-set thresholds. Mobile-connected versions exist for locations without a network. We review this during the evaluation.
Can I monitor several zones or several buildings?
Yes. The system is modular: you can start with the main supply and add floors, units, toilets or buildings. FlowReporter shows one building, or an entire portfolio, on the same dashboard.
Does it replace the building management system (BMS)?
No. It works alongside existing infrastructure. If the building has a BMS, we review integration options during the evaluation. Without one, FlowReporter works independently.
Will it lower my insurance premium?
That depends on each insurer and policy, so we don’t promise a specific discount. What it does provide is documented proof of early detection and automatic shut-off, which insurers take into account when assessing a property’s risk.
What commitment does getting started involve?
None at the evaluation stage. For buildings and portfolios, we usually start with a limited pilot — for example, monitoring at the building entry point — before expanding. There’s no obligation to continue beyond any agreed phase.
