NW2659 - App Development Services

Northumbrian Water Limited (NWL) provides water and sewerage services to approximately 4.4 million people in the North-East of England, Essex, and Suffolk. NWL aims to become the most digital water company globally. As part of this vision, Northumbrian Water Group (NWG) seeks to procure 2+1+1+1 years contracts with up to two suppliers to enhance, develop, and deploy NWL's Field Mobile Apps and Customer Mobile App.

Lot 1: Customer Mobile Apps

NWL has four Customer apps, two for Northumbrian Water customers (iOS and Android) and two for Essex and Suffolk customers (iOS and Android). These apps allow customers to manage bills, create online accounts, make secure payments (credit card, Google Pay, and Apple Pay), check payment due dates, scan meter readings using their smartphone cameras, and access digital PayPoint cards. The apps, developed in Xamarin, utilize Azure API management for mobile-ready APIs, including smart usage data display.

Lot 2: Field Mobile Apps

NWL has five field apps exclusively for employees (iOS). Developed in Xamarin, these apps provide field teams with quick access to information and enable easy input of job-specific data through dynamic forms, which integrate with backend systems. These user-centric apps are regularly updated based on user feedback to enhance customer experience.

E.g. For both lots suppliers will collaborate with NWL's Product and Development teams to:

• Investigate and support system defect resolution, collaborating with Product Management.
• Develop necessary changes and document technical and functional designs.
• Review designs for optimal solutions without compromising existing functionality.
• Provide release notes for production deployments.
• Execute deployments following agreed processes, separating Developer and DBA roles.
• Update progress in the change management system (e.g., Jira).
• Build and unit test code, with detailed documentation for each deployment.
• Facilitate knowledge transfer and ensure environment consistency.
• Support environment refresh (data refresh) for testing purposes.
