Ohme Home Pro

The Ohme Home Pro is the undisputed smart tariff champion in the UK home charger market. It connects directly to your energy provider via API and automatically charges your car during the cheapest half-hour slots, without you having to set schedules manually. If you are on Octopus Intelligent Go, Ohme is the officially recommended charger -- it communicates with Octopus to unlock extended off-peak hours (typically 11:30pm to 5:30am at around 7p/kWh), potentially saving you over £1,000 per year compared to public charging. The charger features a built-in colour display on the front panel, solar diverting if you have panels, and the app provides detailed energy cost breakdowns so you can see exactly what each charge session cost you down to the penny. It comes pre-wired for dynamic load balancing and includes a 3-year 4G SIM for connectivity even if your Wi-Fi does not reach the driveway. For Tesla owners focused on minimising running costs above all else, this is the charger to buy.

Best for: Drivers on smart energy tariffs who want fully automated off-peak charging and detailed cost tracking per session.

Installation

The Ohme Home Pro is one of the lightest and most compact chargers on the market, weighing approximately 3.5 kg and measuring just 170mm x 200mm x 100mm. This makes it straightforward to mount in tight spaces. The standard 5-metre tethered cable is shorter than average -- the Tesla Wall Connector offers 7.3 metres -- so consider your parking position relative to the mounting point carefully. An 8-metre cable version is available at extra cost if you need more reach. The Ohme includes a PEN fault detection device as standard, which is a regulatory requirement and saves your installer from sourcing one separately. However, it does not include a built-in RCD or surge protection device, so these will need to be added at the consumer unit. The charger is IP65 rated, making it fully weatherproof and suitable for exposed outdoor installations without additional shelter.

Tariff Compatibility

This is where the Ohme Home Pro earns its reputation. It has direct API integration with Octopus Energy (Intelligent Go, Go, Agile, Cosy), OVO Energy (Charge Anytime), and British Gas (EV Power+). On Octopus Intelligent Go, the Ohme communicates directly with Octopus to request additional off-peak slots beyond the standard 6-hour window, giving you more hours at the cheapest rate. On Agile Octopus, it reads the next day's half-hourly prices and automatically schedules charging into the cheapest slots to meet your target charge level by morning. This is genuinely hands-off -- you set your departure time and desired battery level, and the charger does the rest. No other charger on this list matches this level of tariff integration. The Tesla Wall Connector and most competitors require manual schedule setting. For a full breakdown of which tariffs work with which chargers, see our guide to the best EV charging tariffs.

Price Breakdown

At £535, the Ohme is priced £60 above the Tesla Wall Connector but delivers significantly more in smart tariff automation. The savings from automated off-peak charging can easily recoup the price difference within two to three months on Octopus Intelligent Go, where you could be charging at 7p/kWh instead of the standard variable rate of around 24p/kWh. If you are eligible for the OZEV grant, the installed cost drops further. The Ohme is genuinely one of the cheapest chargers to run in the long term thanks to its tariff optimisation.

How It Compares

The Ohme Home Pro's closest competitors are the Tesla Wall Connector (for Tesla-native integration) and the Zappi GLO (for solar). For a head-to-head on app integration and tariff features, see our Ohme Home Pro vs Zappi GLO comparison. If you are deciding between the Ohme and the UK's best all-rounder, our Ohme Home Pro vs Hypervolt Home 3 Pro comparison covers the trade-offs between tariff depth and build quality. The Ohme also outperforms the Wallbox Pulsar Max on smart features despite being cheaper -- see our Ohme Home Pro vs Wallbox Pulsar Max comparison for the full breakdown. Bottom line: if you have or plan to get a smart energy tariff, the Ohme pays for itself faster than any other charger on this list.
