The UK’s leading developer of specialised leak detection, water sustainability, flood defence and environmental protection systems, Andel, has supplied 722 FlowStop® 2 smart water protection units to John Sisk & Son for the Great Charles Street development in Birmingham – one of the city’s most significant new residential schemes.
Located on the edge of Birmingham’s Jewellery Quarter, the Great Charles Street project will deliver 722 apartments across three buildings, including a 39-storey tower that will form a prominent addition to the city skyline. The development will also feature extensive resident amenities, commercial space and improved public realm, supporting the wider regeneration of the area.
Following a competitive tender process, the project’s M&E contractor selected FlowStop® 2 to provide apartment-level protection against water leaks and burst pipes across the entire development.
Residents will benefit from extensive shared facilities including fitness, co-working and communal spaces, alongside ground-floor commercial units and enhanced public realm.
Given the scale, density and long-term operational profile of the scheme, protecting apartments from water damage and escape-of-water incidents was a key design consideration.
In large, multi-occupancy residential developments, even a single undetected leak can escalate quickly – causing damage to multiple apartments, disrupting residents, and leading to costly insurance claims and remediation works.
For Great Charles Street, the project team required a solution that could:
The solution also needed to be commercially competitive and straightforward to install at scale within a demanding construction programme.
Following a competitive tender process, the M&E contractor selected Andel’s FlowStop® 2 as the preferred water protection solution for the scheme.
Andel supplied 722 FlowStop® 2 units, providing dedicated protection to every apartment across the development.
Each unit offers multiple layers of protection, including:
FlowStop® 2 continuously monitors water flow and automatically isolates the supply if abnormal conditions are detected, helping to prevent costly escape-of-water incidents before damage occurs. Its combination of NSF REG4 approval, configurable protection settings, strong value for money and suitability for large residential schemes made it a strong fit for a high-rise Build-to-Rent project of this scale.
Supplying FlowStop® 2 to every apartment ensures a consistent approach to water protection throughout the development, helping to reduce risk, protect building assets and minimise disruption for future residents.
The Great Charles Street project further demonstrates Andel’s experience in supporting large-scale residential and mixed-use developments with smart, practical solutions that protect property, conserve water and reduce long-term operational risk.
With insurers paying around £1.8 million every day in the UK for escape-of-water claims, proactive water protection is no longer optional — particularly in dense urban residential schemes.
The successful supply of 722 FlowStop® 2 units to Sisk at Great Charles Street reinforces Andel’s role in supporting contractors and developers with smart, proven technologies that reduce risk, protect assets and conserve water.
