About
Ohme is a UK-based smart EV charging brand that provides home chargers designed to make electric vehicle ownership cheaper, greener, and more convenient. Unlike basic chargers, Ohme's hardware integrates with energy tariffs and grid data to automatically identify the cheapest and lowest-carbon windows to charge — saving the average EV driver more than £500 per year without any manual effort. Ohme chargers are compatible with every major energy supplier and most popular smart tariffs, including Intelligent Octopus Go. For homeowners with solar panels, Ohme can prioritise self-generated renewable energy, reducing reliance on the grid and cutting costs further. Installation is handled by a network of Ohme-approved engineers, making setup hassle-free and compliant with new smart charger regulations. The compact charger design fits neatly into home environments, and the system supports multi-car control for households with more than one EV. The Ohme app is central to the experience, allowing users to set charging schedules, apply price caps, view real-time charge status, and track their historical cost and carbon savings. The platform is designed to evolve with user needs, with future-facing features including seamless tariff switching and expanded solar optimisation. Ohme is trusted by leading automotive manufacturers as an official charging partner and has won multiple industry awards, including Best Electric Charging Point Provider 2025.
