Our Story

Why we built ClearWatt

ClearWatt exists to make the transition to electric feel more measurable, understandable, and trustworthy, especially in the second-hand market.

ClearWatt was borne out of a mutual belief amongst the founding team - that for large-scale EV adoption to become a reality, specific focus is required to provide transparency and clarity on second-hand EVs.
In the UK, 80% of all car purchases are second-hand vehicles; highlighting that the majority of buyers rely on this market to find cost-effective, dependable vehicles. From an environmental perspective, the used car market is essential in ensuring that vehicles have a long lifespan - critical to the overarching objective of EV adoption.
Despite these things, the second-hand EV space has historically been somewhat overlooked; with consumers expected to navigate the extra considerations that come with ‘going electric’ alone. This includes the basics such as choosing the right car and figuring out how you’ll charge it, through to concerns about the reality of range and performance; including how and why this might change as the car gets older.
With all this in mind, we decided to build ClearWatt - a comprehensive, independent suite of much-needed resources specifically designed to help you confidently make an informed electric transition.
