Why we built a community charging marketplace
Six months into building Volta, a user emailed us from Nottingham. She had a home charger, a Tesla, and a driveway that sat empty most weekdays. She asked a simple question: could she make money from it? That email changed the direction of the entire app.
The charger behind the garage door
When we first mapped the UK's 40+ EV charging networks into Volta, we noticed something odd. The coverage maps showed green dots everywhere, but when you actually needed to charge - not at a motorway service station, but in your neighbourhood on a Tuesday afternoon - the network thinned out fast. Drivers were complaining about queues at public chargers while residential streets had private chargers sitting idle.
That Nottingham email wasn't an outlier. We started hearing from venue owners too. A pub in Cornwall had installed a charger to attract EV drivers, but had no way to advertise it or manage payment. A small hotel in the Midlands had two chargers in their car park and wanted to let guests use them, but the logistics felt impossible without some kind of platform.
The problem wasn't really a logistics one, though. It was visibility. People with chargers didn't know how to tell drivers about them. Drivers didn't know where private chargers existed. And no one had built a simple way to bridge that gap in the UK market.
Starting with trust, not complexity
We could have partnered with existing payment processors and built something elaborate. Instead, we chose to keep it simple. The community charging marketplace in Volta lets homeowners and venue owners list their chargers directly in the map. A driver looking at the map sees both public network chargers and private community chargers in one place. The total cost appears the same way it does everywhere else in the app: transparent, combined, upfront.
The arrival experience mirrors our core feature. You see the charger, you see the price, you arrive and check in via the app. For hosts, it's receipt history and earnings tracking without needing to manage separate payment systems or spreadsheets.
What we didn't do is overcomplicate it. No insurance nightmares, no regulatory maze. The host sets the price, the driver books it. If someone runs a fleet and wants to use community chargers as part of their route planning, they can see those chargers in the journey planning tool and request access.
Why this matters more than it looks
Most people don't think about EV charging as a supply problem. They think about it as finding the nearest public station. But the UK's grid and charging infrastructure are in a transition. Public networks are expanding, but they're concentrated in cities and along major routes. Rural areas, suburban streets, and smaller towns have gaps that the public network alone isn't going to fill quickly.
Community charging doesn't replace public networks. It fills the gaps. A homeowner in a village outside York can earn a modest income from their home charger while a local driver stops needing to drive 15 minutes to the nearest public point. A venue gets a new customer attraction without major capital investment. A fleet manager gets more flexibility in route planning and journey cost visibility.
For us as a business, the marketplace is also strategic. It makes Volta more useful to more people. A driver in an underserved area finds private options. A host discovers a revenue stream. Both are stickier to the app because they're getting value that no single network operator could provide.
The numbers we care about
We're not reporting this as venture capital metrics. But we do measure it. In the first month after launch, we saw community chargers listed in 12 regions. By month three, that number had climbed. The average host response time to a booking inquiry is under two hours. More importantly, drivers are using the feature. It's not the majority of Volta's charging journeys yet, but it's growing month on month, and in rural areas it's the second most used charging option after the national networks.
What's more interesting than the raw numbers is the feedback. Hosts tell us they like the simplicity. Drivers appreciate the price transparency. We've had a few edge cases - disputes, accessibility questions - but the community has been surprisingly self-policing and reasonable. People tend to be honest when they're earning money from their reputation.
What comes next for us
The marketplace is still young. Right now, premium users get access to community chargers in their journey planning. We're exploring ways to make it easier for fleet managers to request bulk access to community chargers as part of their policy setup. We're thinking about how accessibility filters work for private chargers, since we built those filters for drivers with accessibility needs and they should apply everywhere.
We're also learning. We're learning which regions have the most host interest. We're learning what charger hosts want from the app that they don't currently have. And we're learning what drives a driver to use a community charger instead of a public network, beyond just price.
The Nottingham user who sparked all this is still hosting. Last we checked, she'd earned enough to cover her charger installation costs in about eight months. That feels like the right kind of outcome: useful to the person using it, sensible as a business model, beneficial to the wider EV charging ecosystem.
The marketplace won't solve the UK's EV infrastructure challenge alone. But it's a reminder that the best solutions often come from listening to people trying to solve their own problems. What would you want from a charging network if you could design it yourself?
