Situation

I joined the 'Growth Studios' team, who pitch new ideas to the business and where confidence is high, they incubate/grow these ideas ready for handover to the 'Go To Market Team'.

The idea we were working on had 2 parts:

  1. Growing the customer base for one of the UK’s lowest off-peak tariffs for EV charging.

  2. A dedicated mobile app (Next Drive Smart) that enables users to specify when they need their car charged for, and how much charge is needed - essential to get the cheapest rates.



Problem

We were working at the pinnacle of modern technology (Kraken) in the time of use tariff space.


Goals

  • Onboard 1,000 customers to the 'Next Drive Smart' Tariff by July 2025.

  • Enable customers to troubleshoot whilst onboarding to the app, to reduce inbound calls.

  • Improve the conversion rate of the landing page.


My Role

  • Evaluated the tariff landing page — explored usability and conversion/fallout data.

  • Joined forces with energy experts (call centre) to understand customer issues whilst trying to onboard to the tariff.

  • Used Qual/Quant insights to re-design the tariff landing page using the 'Go To Market' design system.

  • Evaluated the Next Drive Smart app's EV onboarding experience and simplified the process including language used in the UI.

  • Created FAQ content for the tariff and app.

  • Prototyped new features such as push notifications.
