Leak Detection and Escape-of-Water Loss Reduction

Escape of water (EOW) is one of the most common and costly causes of property damage in UK housing. Water damage from leaks can destroy floors, walls, ceilings, and contents, while creating ideal conditions for mould growth. Early detection dramatically reduces damage and costs.

The Scale of the Problem

According to industry data:

• Escape of water accounts for approximately 25-30% of home insurance claims
• Average EOW claim costs £7,000-10,000
• A small leak can release hundreds of litres per day
• Water damage often affects multiple properties in flats

Common Leak Sources

• Appliances: Washing machines, dishwashers, water heaters
• Plumbing connections: Under sinks, behind toilets, at stop cocks
• Pipework: Particularly in unheated spaces (frost damage)
• Bathrooms: Failed seals around baths, showers, and basins
• Heating systems: Radiator valves, boiler connections, expansion vessels

The Value of Early Detection

The cost of water damage increases exponentially with time:

• Minutes: Wet floor, minor cleanup
• Hours: Flooring damage, potential spread to adjacent areas
• Days: Structural damage, mould growth begins
• Weeks: Extensive remediation required, potential uninhabitability

A sensor that alerts within minutes can reduce damage by 90% or more compared to discovery after days.

Sensor Placement

For maximum protection, place water sensors:

• Under sinks (kitchen and bathroom)
• Behind toilets
• Near washing machines and dishwashers
• Near water heaters and boilers
• In airing cupboards with hot water cylinders
• In basements or areas prone to flooding

Integration with Property Management

Effective leak detection requires not just sensors but also:

• Clear escalation paths when alerts trigger
• Access to emergency isolation valves
• Tenant education on what to do if alerted
• Regular sensor testing and maintenance
