Coverage and data sources
Zapmap has operated since 2008 and has built one of the largest community-verified charging databases in the UK, with over 60,000 connector locations. Its strength is the volume of user-submitted updates and error corrections that flow in from a large established user base. Volta draws from direct network API integrations for supported operators, which means the data it shows for those networks is updated automatically in real time rather than relying on community submissions. For drivers who primarily use large national networks like Pod Point, BP Pulse, or Osprey, Volta's real-time feed is typically more accurate for live availability. For less common or privately operated chargers, Zapmap's community database may have broader coverage.
Pricing and subscription model
Zapmap offers a free tier and a paid Zapmap Plus subscription at £3.99 per month or £24.99 per year. Plus unlocks features including ad removal, filtering by plug type and network simultaneously, and the ability to set vehicle-specific profiles that persist across sessions. Volta's core functionality — map, filters, live availability, and navigation — is fully free with no account required. Volta's Pro subscription unlocks route planning for long journeys and offline map access. For drivers who want a capable charging finder without a monthly commitment, Volta's free tier is more complete than Zapmap's.
Interface speed and usability
Zapmap is a well-established app with a mature feature set, but its interface carries the complexity of years of accumulated features. New users sometimes find the default map view dense with options. Volta is designed around a single decision — find a charger and go — with the map, filters, and navigate button all accessible within one screen and one tap. For drivers who open a charging app quickly in a car park or at a service station, Volta's interface requires fewer taps to reach the information that matters. Zapmap's depth suits drivers who want granular community reviews and fault reports on individual charge points.
How Volta compares to PlugShare and Google Maps EV
PlugShare is a global community platform with strong US coverage but thinner real-time data in the UK. Google Maps added EV charging filters in recent years and benefits from Google's mapping infrastructure, but it does not show live connector-level availability for most UK networks and does not support connector-type filtering at the detail level that dedicated EV apps offer. Volta sits between these options: it has the UK-network depth of Zapmap, a cleaner interface than PlugShare for UK users, and faster charger-specific data than Google Maps without requiring a Google account or opening a separate app.
