Helping Tesco Bank reach the next level

The Challenge

With more than 6.5 million active customer accounts across a range of financial products and services, Tesco Bank makes banking and insurance simple and rewarding, while enabling people to be smarter with their money.

However their mobile application was no longer capable of supporting the highest engineering standards, and they began to search for a partner who could augment their existing delivery teams to rebuild the app from the ground up, while modernising and improving their engineering and design standards.

The team have focused on results and are a highly motivated. I strongly endorse them as a business partner. I look forward to working again with the team to create new innovative digital products again in the future.

The Solution

We had to deliver something that served the needs of Tesco’s customer base that was on a parity of esteem with emerging challenger bank services at base. We needed to deliver this within a tight time frame while making sure we were also building code that could ultimately be inherited by an internal team.

Within eight months of being engaged, we had completely rewritten and launched the updated iOS app. Vital to this was the creation of a stable and maintainable database, plus ensuring a user interface that was accessible and usable by a wide-range of users.

Post-launch we worked in a blended engineering team model, both on-site and off-site and over the course of a number of years, helping deliver the Mobile Banking app across iPhone, iPad, Apple Watch and Android.

We also supported the business on a number of Proof of Concepts for new product innovations utilising Beacons, Wallet concepts and other innovative digital payment use cases which are still live today in Tesco Bank or Tesco stores.

Going Above and Beyond

Security and long term vision were two of the pillars of creating Tesco Bank’s Mobile Banking App. Using our industry experience and security knowledge, we were able to advise Tesco Bank on mobile architecture across its entire mobile estate, produce proof of concepts to help define and understand the vision and help Tesco Bank look to the future with mobile trend and market reports.

The Results

On the face of it, we built a popular, secure, easy to use mobile app for Tesco Bank and its banking customers. But we were also able to help Tesco Bank plan for the future by building a robust and quality app that’s underpinned by a strong architecture, we laid the foundation for what’s to come next.

Across the roll out of the new app, we ensured there were no service interruptions when transitioning customers from the old app to the new one.

Throughout the project, we built a strong relationship with Tesco Bank and for the past five years, we’ve managed the transfer of complicated projects to its internal team and have built projects from Telematics to a travel money platform.
