Ohme Home Pro vs Andersen Quartz

What £133 buys — and what it doesn't

The Ohme Home Pro costs £539. The Andersen Quartz costs £672. That £133 gap doesn't buy you more power — the Ohme delivers 7.4 kW, the Andersen 7.2 kW. It doesn't buy you better smart-tariff support. What it does buy is eleven colour finishes, optional Accoya and carbon inserts, a seven-year warranty, and the quiet satisfaction of a charger that looks like it belongs on a Georgian terrace rather than a distribution board.

Whether that trade is worth making depends on a single question: do you care more about what the charger does with your electricity, or what it looks like while doing it?

• Ohme Home Pro — £539. The tariff-chasing charger. Direct API integration with Octopus, British Gas, and more. Built-in 4G. Three-year warranty.
• Andersen Quartz — £672. The design-led charger. Seven-year warranty. Eleven finishes. Intelligent Go and OVO integration, but no half-hourly Agile optimisation.

The Ohme's tariff advantage is not subtle

The Ohme Home Pro has direct API integration with Octopus Intelligent Go, Octopus Go, Octopus Agile, and British Gas EV Power. It doesn't just schedule around a fixed off-peak window — it chases half-hourly pricing on Agile, and on Intelligent Go it's the charger Octopus themselves recommend. That recommendation is not ceremonial; it means the Ohme can accept bonus off-peak slots pushed by Octopus outside the standard 23:30–05:30 window, filling your battery opportunistically when the grid is cheap.

The Andersen Quartz added Intelligent Go support in September 2025, and it works with OVO Charge Anytime. That's a reasonable smart-tariff offering — better than most chargers in the catalogue. But it doesn't match the Ohme's breadth. On Agile, where rates shift every thirty minutes and the savings compound, the Andersen has no equivalent. It schedules; it doesn't chase.

On a flat-rate tariff, none of this matters. Both chargers will charge overnight on a timer, and neither earns back its price through cleverness. But if you're on — or moving to — a time-of-use tariff, the Ohme is the more capable tool by a clear margin.

The Andersen's case: warranty, finish, and the OZEV question

Seven years. That's the Andersen Quartz's strongest card. The Ohme offers three. The Tesla Wall Connector offers four. The Wallbox Pulsar Max offers five. Only the Andersen A3 and Simpson & Partners Home 7 match or exceed the Quartz here. For a device bolted to the outside of your house, exposed to British weather for the next decade, that warranty length is a material consideration — not a marketing line.

Then there's the finish. Eleven standard colours, with Accoya wood and carbon-fibre inserts available. The Ohme is a neat, compact white box. The Andersen looks like someone thought about it. If the charger sits beside your front door, visible from the street, that thought has a value the spec sheet can't capture.

The complication: OZEV approval. The Ohme Home Pro is on the approved list. The Andersen Quartz, as of this writing, is not confirmed. For eligible renters and flat owners, that £500 grant would bring the Ohme down to £39 plus installation — a dramatic number. The Andersen, without the grant, stays at £672. That turns a £133 gap into something much wider for grant-eligible buyers. Verify the Quartz's OZEV status before committing.

Connectivity and practical differences

The Ohme includes a 4G SIM, active for three years. If your Wi-Fi doesn't reach the driveway — and in plenty of UK homes it doesn't — the Ohme stays connected regardless. The Andersen relies on 2.4 GHz Wi-Fi and Bluetooth for setup. A solid home network handles this fine; a weak signal to a detached garage does not.

Cable length is close: the Ohme ships with 5 metres (8-metre option at extra cost), the Andersen with 5.5 metres (8.5-metre option for £99). The Andersen also offers a socketed (untethered) version — useful if you have two EVs with different connectors, or if you prefer a tidier wall when the car's away.

Both are IP65 rated. Both handle solar diversion — the Andersen via an included CT clamp, the Ohme with built-in logic. For homes with panels where solar is the primary concern, the Ohme vs Zappi GLO comparison covers that ground more thoroughly.

Which to buy

Buy the Ohme Home Pro if:

• You're on, or planning to move to, a smart tariff — especially Agile or Intelligent Go
• You're eligible for the £500 OZEV grant
• You want 4G backup connectivity without relying on your home Wi-Fi

Buy the Andersen Quartz if:

• Finish and colour choice matter — the charger is visible and you want it to look deliberate
• A seven-year warranty outweighs a three-year one in your calculation
• You don't need half-hourly tariff optimisation and are content with Intelligent Go or OVO scheduling

For most buyers reading this page — people comparing two chargers, weighing features against price — the Ohme Home Pro is the stronger pick. It costs £133 less, it does more with your tariff, and it stays connected where the Wi-Fi fades. The Andersen Quartz is a fine charger with a warranty that outlasts most of the field, but its premium buys aesthetics and longevity, not smarts. If the wall matters as much as the bill, the Andersen earns its place. If it doesn't, keep the £133.
