Project overview

Mercury NZ is a leading electricity generation and multi-utility retailing company. In 2022 Mercury acquired Trustpower and needed a new app as part of a larger project including a new public website and self-service portal. While working at Catch Design (a digital partner to Mercury for some time) I was involved from the beginning as the Lead Designer for the app, responsible for working through the UX and execution of new UI for the native app (iOS and Android). Working to a strict deadline and as part of a close agile team with the project owner, marketing lead, developers and other designers, good communication throughout the process was key.

Challenge

The challenge was to combine the best of both Mercury and Trustpowers existing services and create a new experience for both existing and new customers. The goal was to establish a unified design language and consistent experience shared across the app, website, and customer portal. Business goals included increasing conversion rates and sales, reduced cost to serve, reduced churn rate and better accessibility for all users.

The project provided an opportunity to completely rethink and redesign the app experience – looking to the latest UX and design practices and trends to provide the best customer experience possible.
