Ohme Home Pro vs Andersen Quartz: £160 for a prettier wall

£160 buys you a longer warranty and eleven paint colours

The Ohme Home Pro costs £535. The Andersen Quartz costs £695 — £160 more. Both are tethered, single-phase, IP65-rated chargers that will put roughly 7 kW into your car overnight. The question is what you get for the extra money, and whether any of it matters once the unit is bolted to the wall and you stop looking at it.

• Ohme Home Pro — £535. Direct smart-tariff integration across Octopus, OVO, and British Gas. Three-year warranty. OZEV-approved.
• Andersen Quartz — £695. Seven-year warranty, eleven standard finishes, PEN fault detection built in. OZEV approval not confirmed.

The Ohme Home Pro on smart tariffs

This is where the £160 gap starts to look generous to the Ohme. The Home Pro has direct API links to Octopus Intelligent Go, Octopus Agile, OVO Charge Anytime, and British Gas Electric Drivers. On Intelligent Go at 7p/kWh, it slots charging into every available cheap half-hour without you touching the app. On Agile — where rates shift every thirty minutes — it chases the lowest slots automatically.

The Andersen Quartz added Intelligent Octopus Go and OVO Charge Anytime support in September 2025, which narrows the gap on those two tariffs. But it still cannot follow Agile's half-hourly pricing, and it has no British Gas integration. If your tariff strategy goes beyond a fixed off-peak window, the Ohme does more. If you are on Octopus Go — a simple 00:30–05:30 block at 8.5p/kWh — either charger handles a manual schedule. But the Ohme still costs £160 less.

The Ohme also carries a built-in 4G SIM, active for three years, which matters if your garage is at the far end of a Wi-Fi dead zone. The Quartz relies on 2.4 GHz Wi-Fi and Bluetooth.

The Andersen Quartz's case: warranty and finish

Seven years. That is the Quartz's strongest argument — more than double the Ohme's three-year cover. Over a decade on a driveway, exposed to British weather, a longer warranty has real value. The only other charger in our catalogue matching seven years is the Andersen A3, at £995.

Then there is the look of the thing. Eleven standard colours, optional Accoya wood and carbon-fibre inserts — the Quartz is designed for front-of-house walls where a glossy black rectangle would jar. If your charger sits beside a period front door or a painted render, this matters. If it sits inside a garage, it does not.

PEN fault detection is built in, so you will not need an earth rod — a saving of perhaps £50–£100 on install, depending on the electrician. That chips into the £160 premium, though it does not erase it.

The OZEV question

The Ohme Home Pro is OZEV-approved. The Andersen Quartz is not confirmed on the current eligible list. For renters and flat owners who qualify, the £500 OZEV grant applies to the Ohme but may not apply to the Quartz. That could flip a £160 premium into something far larger in practice. Verify the Quartz's status before committing — but right now, the Ohme is the safer route to the grant.

Which to buy

Buy the Ohme Home Pro if:

• You are on, or plan to switch to, a smart EV tariff — especially Agile or Intelligent Go
• You want OZEV grant eligibility without checking small print
• You would rather spend £160 less and accept a shorter warranty

Buy the Andersen Quartz if:

• A seven-year warranty matters more to you than tariff automation
• Your charger will be visible from the street and you want it to look deliberate
• You are already on Intelligent Go or OVO Charge Anytime and do not need Agile support

For most Tesla owners choosing between these two, the Ohme Home Pro is the more useful charger at the lower price. It earns back more than its cost through tariff integration, it qualifies for the grant, and it does the hard work — chasing cheap electricity — that a charger should do in 2026. The Quartz is a handsome piece of hardware with a warranty to match, but £160 extra for fewer smart features is a difficult ask unless the finish on your wall is the thing keeping you up at night. If it is the Andersen aesthetic you want but the Quartz still feels like a compromise, the Ohme Home Pro vs Andersen A3 comparison is worth a look — though the price gap there is considerably wider.
