GRIDSERVE was expanding rapidly, but the mobile experience needed to evolve alongside growth. The opportunity was to create a scalable product that not only enabled charging, but also generated meaningful customer insight to inform future decisions.
GRIDSERVE - Shipped an EV charging app from brief to 50,000 downloads.
/Role
Lead Product Designer — UX, UI, prototyping, motion, stakeholder alignment, design QA, engineering handover.
/Context
B2C native mobile EV charging app across search, charging, payment, live progress, receipts, and account management.
/Impact
Launched in under six months, reached 50,000+ downloads, achieved a 4.8-star app rating, and created a scalable mobile foundation.
GRIDSERVE was expanding rapidly, but the mobile experience needed to evolve alongside growth. The opportunity was to create a scalable product that not only enabled charging, but also generated meaningful customer insight to inform future decisions.
Set the design direction across the full product, working directly with iOS and Android engineers throughout — from early direction-setting through to iterative delivery and final review. Maintained design integrity across the product as the sole designer from discovery to contract close.
Early requirements workshop in FigJam aligning stakeholders around product priorities and scope.
Journey wireframes shaping core charging flows and aligning business priorities with technical feasibility.
EV charging is a trust based interaction. Clear communication, predictable flows, and transparent feedback directly influence adoption and repeat use.
Research trip with GRIDSERVE exploring the live EV charging experience, identifying customer pain points and capturing in-session UI that directly informed the mobile design.
Served as the sole designer across the entire product, owning end-to-end design from early discovery through to launch and beyond — spanning search, charging, payments, and account management.
Organised and led direct customer research at live GRIDSERVE charging sites — the first time the business had spoken directly to its users. Translated those findings into clear product decisions that grounded the design in real behaviour rather than assumption.
Facilitated early requirements workshops with cross-functional stakeholders, aligning product leadership, engineering, and client teams around priorities and scope before a line of design was drawn.
Set the visual and interaction direction for the core charging experience, including the session dial — designed to present live charging data in a way that was immediately legible and meaningful to users, not just technically accurate.
Established scalable design foundations and Figma conventions that supported engineering handover at pace, and remained embedded in the product through to contract close.
End to end charging journey from charger ID entry through to live session monitoring and digital receipt.
Launched the GRIDSERVE mobile app in under six months, accelerating digital capability during rapid national growth.
Achieved a 4.8 star rating from 5,000+ reviews, signalling strong product market fit.
Surpassed 50,000 downloads, driving early adoption at scale.
Established core charging journeys that reduced friction across Find, Charge, and Pay.
Enabled structured customer data capture, strengthening marketing and service optimisation.
