What stands out
Main limitation
The installed range is an estimate. The source date above is separate from the editorial review date.
Several chargers here talk to your energy supplier. This is the one that gets the most out of it. On Octopus Intelligent Go, the Ohme pulls extra off-peak slots out of Octopus's API and charges your car while the grid sleeps — the published base window is 11:30pm–5:30am at 8p/kWh. On Octopus Agile, it reads tomorrow's half-hourly prices and books the cheapest ones overnight. Set your departure time and target percentage; it does the rest.
Everything else — 7.4kW single-phase, 5-metre cable, colour display, solar diverting, built-in 4G SIM for the first three years — is competent rather than remarkable. On a smart tariff, the integration is the point. On a flat-rate tariff, the Tesla Wall Connector does the same hardware job for £64 less.
Best for: Anyone on Intelligent Go, Agile, or British Gas EV Power+ — any tariff with more than two rates.
Installation
Fitting the Ohme Home Pro.
Light and small — 3.5 kg, 170 × 200 × 100 mm — one of the easier mounts in this selection. The standard 5-metre tethered cable is shorter than the Tesla's 7.3 m and the Hypervolt's optional 10 m, so position the unit close to where the car sits, or pay for the 8-metre version. PEN fault detection is built in — one component the installer doesn't need to source. RCD and SPD still need adding at the consumer unit. IP65: fully weatherproof, no shelter required. Full walkthrough in our install guide.

Tariff compatibility
What it costs to run.
This is the entire argument for the charger. On Intelligent Go, Octopus holds a live link to the Ohme and negotiates extra off-peak slots beyond the standard six-hour window — more than the chargers that are merely on Octopus's approved list get. On Agile, no supplier controls any charger: the Ohme reads the day-ahead prices Octopus publishes each afternoon and books the cheapest half-hours itself. Only the Zappi GLO does the same. British Gas EV Power+ is supported too. For the full pattern, see our smart-tariff chargers guide.

Compare every tariffPrice
What you actually pay.
The unit is currently £539. £400–£500 is the working installation range, putting a typical installed total at £939–£1,039. Charger only; standard installation packages start at £999.
Five-year total
£1,703
Charger, installation, and five years of electricity on Octopus Agile, at 10,000 miles a year.
Less £500 if you qualify for the OZEV grant.
Against the field
How it compares.
Against the Tesla Wall Connector: wins on tariff automation, loses on cable length and price. Against the Zappi GLO: wins on tariff automation, loses if you have solar panels. Against the Hypervolt Home 3 Pro: wins on tariff automation, loses on weatherproofing and cable options. The pattern is the pattern. Head-to-heads: vs Zappi, vs Hypervolt, vs Wallbox.
Cross-shopped with
What we loved
- PlusDirect API integration with Octopus and British Gas — the charger chases the cheap half-hours without you
- PlusOfficially recommended by Octopus for Intelligent Go
- PlusBuilt-in solar diverting; no separate CT clamp to buy
- PlusBuilt-in 4G SIM for three years — works where the Wi-Fi doesn't reach
- PlusColour display with detailed per-session cost tracking in the app
- PlusIP65 — fully weatherproof
What we didn't
- MinusSingle-phase only; no 22kW three-phase option
- Minus5-metre cable as standard; the 8-metre version costs extra
- MinusOn a flat-rate tariff, the £64 premium over the Tesla Wall Connector is hard to justify
- MinusThree-year warranty where the Tesla manages four and the Wallbox five
