Ohme has become the de facto UK leader for tariff-optimised home charging by 2026 — primarily because Ohme is the only major UK charger that pulls the vehicle\'s state of charge directly from the OEM telematics API (Tesla, Hyundai/Kia, Ford, Polestar and the VW group). That lets Octopus Intelligent Go schedule charge sessions against the actual battery level and the car\'s departure-time setting, rather than guessing from charge-session history. Real-world the result is the cleanest 7p/kWh tariff capture of any UK charger — typically £600/year saving for an 8,000-mile-per-year driver moving from a flat-rate tariff.
The Ohme Home Pro is the flagship: 7.4kW single-phase Type 2 tethered (8m cable), built-in 4G modem (no Wi-Fi required — important in concrete-walled flats and basement garages), 5-inch colour screen for session control without the app, and PEN-loss protection built in (no separate earth rod needed on TT/PME conversion installs). The ePod is the slimmer entry-level unit: socket-only, smaller, no screen, same OCPP and tariff support, sold at a notably lower price point. Both are Ohme Approved Installer products with a 3-year manufacturer warranty.
The main alternative in this tariff-optimised category is the MyEnergi Zappi — best for solar self-consumption (eco modes that ramp the charger up only on surplus PV), but Zappi\'s Intelligent Go integration runs through hub.io.energy rather than a direct vehicle API, so the scheduling intelligence is a step behind Ohme\'s. For a household with both solar and Octopus Intelligent Go, Zappi often wins; for pure tariff-optimised charging without solar, Ohme is the stronger pick.

Frequently asked questions
Ohme vs Pod Point vs Wallbox in 2026 — which is best?
Ohme: best tariff capture (only UK charger that pulls SoC from the OEM API), best for Octopus Intelligent Go drivers. Pod Point: best app polish, EDF integration, mainstream UK choice. Wallbox Pulsar: best compact form factor, strong Apple-style hardware design, slightly weaker tariff integration. For pure off-peak charging with Octopus, Ohme wins. For ecosystem polish, Pod Point. For premium hardware aesthetics, Wallbox.
How much does Intelligent Go actually save with Ohme?
Real-world data from London Ohme + Intelligent Go installs in 2025–26: roughly £600/year saving for an 8,000-mile driver moving from a flat-rate 28p/kWh tariff. The 7p/kWh off-peak window pays for the difference inside 2 years on a £795 install — and that's before the OZEV grant kicks in for eligible flats and landlord installs.
Why 4G instead of Wi-Fi — is it reliable?
Yes. The 4G modem is built-in with a multi-network SIM (EE, Vodafone, O2 fallback) and data is included for the life of the product by Ohme. It works in basement garages, concrete-walled flats, terraced houses where the meter cupboard is at the front and the parking is at the back, and any other property where Wi-Fi reach is patchy. Wi-Fi-only chargers (older Pod Point, Wallbox) often fail in exactly these London geometries.
Home Pro vs ePod — which one for me?
Home Pro if you want the 8m tethered cable (no plug to manage in the rain), the 5-inch screen (start/stop/status without unlocking your phone) and PEN-loss protection built in. ePod if you want the cheaper price and don't mind plugging in your own Type 2 cable each time. Both run the same tariff integration — the difference is hardware convenience, not software capability.
Can I balance two Ohme chargers on one driveway?
Yes. With two Ohmes on the same household supply, the setup we run shares a current limit across the pair — both can charge simultaneously at half power, or one car charges at full 7.4kW if only one is plugged in. The £125 multi-vehicle setup is a commissioning-side configuration; no extra hardware is needed.
What permissions does the Ohme app need?
For OEM API integration: read-only access to your vehicle's state of charge, charge-session history and departure-time setting. The Ohme app does not need to start/stop charging via the vehicle — that goes through the charger itself. Permissions are revocable from the vehicle manufacturer's account (Tesla, Hyundai etc) at any time.
What happens if the 4G signal drops?
The charger caches the most recent tariff schedule locally. If 4G drops mid-session, the unit continues charging on the cached schedule and uploads session data when connectivity returns. Persistent 4G failure (rare) falls back to a manual scheduled-window mode — you set the off-peak window in the screen UI directly.
What warranty comes with the charger?
3 years manufacturer warranty from Ohme on the hardware. Our installation carries a 2-year workmanship warranty on the cabling, mounting, RCBO and SPD work. As an Ohme Approved Installer the full hardware warranty stands — non-approved installs can void it.
