Our Purpose

We provide expert advice and support to our customers (mainly retail customers) on impact assessments, performance analysis and resilience matters for transport, power and water distribution networks. We promote better understanding to build sustainable, efficient infrastructure meeting today's needs and compatible with tomorrow.



Engineering Future Resilience


Belrain Ltd was established in 2018 to deliver high-tier technical support for the Retail Water sector. Initially focused on the management and optimisation of Water Supply and Distribution Systems, we have since evolved into a premier multi-disciplinary infrastructure advisory and consultancy.

Headquartered on London’s prestigious Wenlock Road and led by Teddy Belrain, we aim to bridge the gap between complex engineering and strategic asset management.


We partner with elite engineers and management consultants who bring a proven track record across the Water, Transport, and Power sectors. By combining deep technical design with seamless IT integration, we provide a holistic service that:

 - Optimises Operations: Integrates fragmented network activities into a unified strategy.

 - Drives Efficiency: Delivers significant operational and financial savings for network managers.

 - Ensures Precision: Leverages extensive experience in network analysis and infrastructure planning.

At Belrain Ltd, we don't just provide advice; we provide genuine expertise. Our clients benefit from a team that has successfully navigated the complexities of large-scale infrastructure projects, ensuring every asset is future-proofed and value-driven.
