Water Leak Detector and Alarm Systems

Aqualeak are leading specialists in water leak detection equipment and services.  Our products and services include the supply, design, installation and maintenance of a wide range of flow, sensor and distance measuring systems from  single zone water leak detector systems for the domestic market right through to complex multizone ones for commercial properties.  Whatever your requirement we have the expertise to protect your property from costly and disruptive water damage.

Flow, Sensor, Distance Measuring and BREEAM Leak Detectors


Water flow monitoring or flow based equipment works by monitoring the volume and length of time water is passing through a water pipe.

The monitored flow is constantly compared to preset and adjustable thresholds which reflect a property’s typical water usage. When these thresholds are exceeded, the device assumes an escape of water incident has occurred, immediately and automatically shutting a valve, isolating the supply line from the water mains and minimising the leak .

A flow based water sensor is often recommended for retrofit residential and small commercial applications due to their ability to monitor an entire property for water leaks from a single point, and the relative ease of installation.


Sensor based water leak detectors work by using one or more of spot water sensors, probes and cable/distance measuring cable, to identify water pooling. When water is detected, this information is fed back to a central control panel which will act to stop water flow and/or raise an alarm.

Sensor-based water leak alarm systems can be single or multi-zone. Single- zone systems monitor one specific area, while a multi-zone system can monitor up to 500 separate areas.


Distance-measuring water leak detectors provide pinpoint accuracy in identifying where an escape of water has taken place. Using distance-measuring sensor cable, the below control panels can locate water leaks within a range of +/- one metre. This type of system is appropriate for areas where long runs of water leak detection sensor cable are required, typically greater than 20m.  


BREEAM leak detection systems are capable of detecting major water leaks on the water supply between and within a building and the site boundary.

Aqualeak played a significant role in the development of the BREAAM leak detection criteria when the standards were originally drafted. As a result, we have an excellent understanding of how its technology can help customers comply with the BREAAM assessment method.

Today, Aqualeak offers a range of BREEAM compliant products and systems.

The Right Water Leak Detector for the Requirement

We’re sometimes asked what’s the best water leak detector?  The type you require typically depends on the type of property the system is being installed in, the number of zones that require monitoring, should it meet BREEAM requirements and the actions that you require the system to take when water leaks occur. However, leak detection equipment is not one-size-fits-all and Aqualeak, being a specialist in the supply of water leak detection systems, recognise that each project is different.

Our highly experienced team work with customers – including developers , Mechanical & Electrical engineers, property and facilities management and individual homeowners – to help them design a system that meets their specific requirements.

Our UK team can review and mark-up project drawings, conduct site surveys and make recommendations to ensure the most effective solution, while navigating some of the challenges in incorporating leak detection equipment into a project’s design. We have also developed an introductory guide to leak detection that can help you start the process, but to discuss your requirements in more detail, please email us or telephone 01249 715698 to speak to our team.

Aqualeak are leak detection specialists, as such we not only provide our customers with equipment and consultation, but also a range of associated services, including:

  • installation – our in-house team and network of approved installers are highly experienced in implementing systems
  • Maintenance – systems are not simply ‘fit-and-forget’ and require regular maintenance to ensure they are working effectively and detectors are free of damage
  • Commissioning – full system commissioning ensures that systems are working properly prior to handover
  • After-sales technical support – on-the-phone and email advice from experienced engineers
  • CPD – we offer a free-of-charge seminar covering an introduction to water leak detectors. This session is accredited by the Chartered Institute of Building Services Engineers (CIBSE). Find out more here

The cost of a system will vary depending on the level of monitoring required. However, as part of our consultation process, our experts ensure that we offer all of our customers the most cost effective solution for their specific requirements.

Taking care of the environment 

Water is an increasingly scarce resource in the world and is rapidly rising up the sustainability agenda as a major priority. Water leak prevention and detection technology is one part of the overall mix of measures by which unnecessary water usage can be prevented. Systems can make buildings more environmentally sustainable and efficient, helping to protect one of nature’s most precious resources, while potentially keeping your water bill down..

As anyone without a water leak detector and automatic water shutoff system, who has had the misfortune to experience it will tell you. Significant water damage to your property, caused by a burst water pipe or persistent leak often in central heating systems and underfloor heating systems, can be hugely costly, disruptive and stressful for all those involved, regardless of the type of property. You’re unlikely to unlikely to detect water leaks from the leak noise, even if there is one, the ambient noise, particularly in commercial properties will usually cover it up.

There is the tangible cost of the property damage – refurbishment and restoration, lost revenue and increased insurance premiums. But there are also the intangible costs – the inconvenience of relocating for a significant period of time, loss of priceless or sentimental items and the potential for reputational damage caused by business downtime.

Damage caused by water leaks is the number one cause of property insurance claims in the UK today, accounting for almost £1 billion last year, eclipsing other causes such as fire damage. And the risk is growing. A range of factors is driving the rise in serious water damage, including:

  • the increasing complexity of modern plumbing systemsresidential water leak detector
  • the growing number of integrated, plumbed-in appliances
  • modern methods of construction and the use of less resilient materials
  • a rise in the popularity of push-fit water pipes
  • ageing pipework in existing properties

By now your own UK insurance company will have recognised that installing a water leak detector can play a significant role in mitigating the risk of a leak from happening, minimising water damage and the associated costs they incur. Insurers are actively encouraging customers, both domestic and commercial, to implement Insurance approved leak detection systems.  In addition the Construction Insurance Risk Engineers Group (CIREG), an industry group of insurers and risk management companies, has issued best practice guidance on managing risk of escape of water across the lifecycle of a property, from design and construction through to occupancy. Aqualeak are leak detection specialists, as such the systems we supply will help customers meet the guidance as set out by CIREG. We can also consult with customers to help design and integrate leak detection equipment at both the shell, core and fit-out stages of a project.    

An insurance approved water leak detection system alerts the user to a problem, triggering important preventative actions, such as automatically shut off the water supply . All of this helps to ensure early warning and response to an escape of water incident, enabling it to be addressed in good time. Systems that we have installed have saved customers hundreds of thousands of pounds in insurance claims by identifying problems before they became catastrophic.
