Ohme Home Pro review

The Ohme Home Pro is a tethered 7.4kW smart charger built around Intelligent Octopus Go (IOG), Octopus’s cheap-rate tariff for EV owners. It is among the cheapest chargers once fitted, and because it carries its own 4G SIM it does not need your home Wi-Fi to reach the driveway. The catch is the flip side of that design: when the signal drops, the smart bit stops working, and on IOG that can cost you.

Price and what’s included

Ohme sells the Home Pro from £999 including standard installation, for the 5m tethered version. The charger on its own is around £532 at electrical wholesalers.

Ohme’s standard installation covers an exterior wall mount, connection to your fuse box (consumer unit) and app set-up. Ohme’s own pages disagree on how much cable run is included: its FAQ says up to 15m, its installation page says up to 10m. Get the figure in writing before you book. Energy suppliers charge more for their bundles. Octopus’s standard job covers up to 10m of cable and adds fees for longer runs, and E.ON Next quotes for a 0 to 5m run. Both show prices before a postcode quote, so yours may differ. Our installation cost guide explains what pushes a quote up.

Where to buy (prices seen on 10 October 2026, and they can change):

• Currys: From £999 incl. standard installation, fulfilled by Ohme approved installers; Currys page text still mentions OVO Charge Anytime and may be stale
• ElectricPoint: Charger only £531.99 (5m), £619.99 (8m)

Smart features and tariffs

IOG is where the Home Pro earns its score. Octopus lists it as generally available, and Ohme’s integration is the longest-standing: Octopus published its Ohme FAQ in July 2022. Charging is controlled in the Ohme app, with a “Ready by” window of 4am to 11am. The charger also works with Octopus’s Intelligent Drive Pack, and on any other tariff you can enter your own rates and a price cap. Our Intelligent Octopus Go explainer covers the tariff itself.

There is one common trap. If your car is IOG-compatible, Octopus will offer the car route first. To use the charger route you ask Octopus to switch you, and you must not link both, because that causes schedule conflicts.

Solar is a real feature rather than an afterthought. Ohme’s Solar Only mode starts charging at 1.44kW of surplus and Solar Boost starts from 0.72kW, topping up from the grid. Both need a working CT clamp and a charger installed from January 2023 onwards, and Ohme warns that some older chargers may not be eligible for the firmware. The CT clamp is in the box and Ohme says it fits one in almost all installations, which also gives you dynamic load balancing. See our guides to solar EV charging and CT clamps.

Day to day, you get a colour screen with three buttons, multi-car profiles, approve-each-plug-in, a button lock and over-the-air updates. Ohme does not publish OCPP support (the open standard that lets a charger move to another provider’s app), and two retailers list it as unsupported.

Installation and safety

The Home Pro has built-in PEN fault protection, so an earth rod is not normally needed. If that term is new to you, our PEN fault and earthing guide explains why it matters on PME supplies. The unit also has Type A 30mA RCD protection with integral 6mA DC leakage detection. Ohme does not fit overcurrent protection inside, so your installer adds a breaker (it recommends a 40A Type B MCB).

The case is rated IP55 and IK08, which is fine for a sheltered wall but a step below Hypervolt’s IP66 and IK10. It is small at 170 x 200 x 100mm and weighs 4kg, with a holster for the cable. Electrifying notes that the cable needs somewhere to hang. The UK model is single-phase only, and the warranty is three years on parts and labour including on-site help, with the 4G data covered for those years.

What owners report

Ohme’s record is good with a few caveats. In the What Car? owner survey (brand-level, and published on a page sponsored by Pod) Ohme came 4th of 11. Owners rated installation highly and reported a joint-lowest 13% fault rate, but 27% of those with faults said they were still unresolved. A What Car? staff member who has used a Home Pro since 2022 calls it consistently reliable. Auto Express’s Driver Power 2024 put Ohme 5th of 8, second for customer service and third for build quality but sixth for reliability.

Reviewers are warmer than owners. TechRadar gave it 4/5 after five months on IOG, noting the savings but warning that the best results depend on a supported tariff and that not every EV is fully supported. Honest John found it very reliable with an excellent app and criticised only a plain design.

The complaints that recur on Speak EV are about connectivity. Owners report the charger dropping offline and then charging at the peak rate, and Ohme confirms that behaviour. A platform outage ran from 16 to 19 August 2024, and in July 2025 the app lost tariff cost data and showed spurious tamper alerts until Ohme fixed it server-side. One thread discusses units around four years old going offline after the warranty ended; Ohme says it still issues updates.

How it compares

The Ohme Home Pro’s closest rivals depend on what you value. The Ohme ePod is the same software in a smaller untethered box. The Hypervolt Home 3 Pro is tougher and tops owner surveys, but needs good Wi-Fi. The myenergi zappi is the solar specialist. Our head-to-heads on Ohme versus Hypervolt and Ohme versus zappi go into more detail.

Our verdict

We score the Ohme Home Pro 7.4 out of 10. It is strongest on smart features (9.5) and safety (9.1), and weakest on flexibility (3.5) because it is tethered only with no OCPP. If you are on IOG, want a compact unit, or cannot get Wi-Fi to the wall, it is the one to beat. It is covered in full in our best home EV chargers roundup.

Pick something else in three cases. Choose the Hypervolt for an exposed wall, a long cable run or OVO. Choose the zappi if solar or a three-phase supply drives the decision. Choose the ePod if you want the same brain in an untethered unit. The full scoring is on how we research.
