The EO Mini Pro 3 is the sharper buy for most people — smaller, cheaper, OZEV-eligible, and functionally comparable. The Andersen Quartz earns its £145 premium only if you want the finish, the 7-year warranty, or a longer cable — and can live without the grant.

What £145 buys — and what it doesn't

Both chargers deliver 7.2kW. Both include a CT clamp for solar diversion. Both have scheduling apps and tethered Type 2 cables. The EO Mini Pro 3 costs £550. The Andersen Quartz costs £695. The £145 gap buys you four extra years of warranty, a choice of eleven finishes, and — if you need it — an 8.5-metre cable option. It does not buy you faster charging, better smart-tariff logic, or OZEV eligibility.

  • EO Mini Pro 3 — the smallest mainstream charger on the UK market. A5-sized, OZEV-approved, built for tight spots and practical budgets.
  • Andersen Quartz — Andersen's entry point. Handsome, IP65, 7-year warranty, but not confirmed OZEV-approved and £145 dearer.

The grant changes the arithmetic

The EO Mini Pro 3 is OZEV-approved. For eligible buyers — renters and flat owners — the £500 grant against a £550 unit leaves just £50 for the charger itself, with the rest absorbed into install costs. That is a remarkable deal for a charger with solar diversion, Ethernet, and tariff presets.

The Andersen Quartz is *not* confirmed on the OZEV eligible-chargepoint list. If you qualify for the grant and the Quartz isn't on the list, the real gap between these two isn't £145 — it's £645. That alone settles the question for any grant-eligible buyer. Take the EO.

Warranty and build: where the Quartz justifies itself

Three years versus seven. The EO's warranty is average; the Quartz's is among the longest in the market, matched only by the Andersen A3 and the Simpson & Partners Home 7. If you plan to stay in your home for a decade and want a charger that's covered for most of that, the Quartz offers peace of mind the EO cannot.

The Quartz is also IP65 to the EO's IP54 — a meaningful difference on an exposed wall that catches rain sideways. And it has PEN fault detection built in, which means no earth rod. The EO doesn't advertise this, so your installer may need to add one — a small extra cost and a hole in your garden.

Tariff integration: a draw with one exception

The EO app includes presets for Octopus Go, EDF GoElectric, and several others. The Quartz integrates with Intelligent Octopus Go and OVO Charge Anytime. Neither charger handles half-hourly tariffs like Octopus Agile with the fluency of the Ohme Home Pro — if Agile is your tariff, neither of these is the right charger.

The Quartz's Intelligent Go support is worth noting for Tesla owners specifically. That integration lets Octopus slot charging into cheap half-hour windows automatically — the car and the grid talking through the charger. The EO's presets are simpler: set a window, stick to it. On a fixed off-peak tariff like standard Octopus Go, both approaches land in the same place. On Intelligent Go, the Quartz has the edge.

If you're a British Gas customer, the EO has a Hive Power+ variant that credits back 25% of charging costs on the EV Power+ tariff. No other charger offers that. It's a narrow advantage, but a structural one — the discount compounds every session.

Size: the EO's real argument

215 × 140 × 100 mm. Roughly an A5 notebook. At 2.5 kg, it can sit beside a doorbell without looking industrial. If your charging spot is a narrow garage pillar, a recessed alcove, or a wall shared with a gas meter, the EO is often the only charger that physically fits. The Quartz, at 286 × 172 × 110 mm, is compact by normal standards but nearly twice the footprint. For most driveways this doesn't matter. For awkward installs, it's decisive.

The EO also offers Ethernet alongside Wi-Fi and Bluetooth — a wired fallback that the Quartz lacks. In a metal garage or a thick-walled outbuilding where Wi-Fi drops, Ethernet is the difference between a smart charger and a dumb one.

Which to buy

Buy the EO Mini Pro 3 if:

  • You qualify for the OZEV grant — the maths aren't close
  • Your mounting spot is tight, awkward, or space-constrained
  • You're on British Gas and the Hive Power+ 25% cashback applies

Buy the Andersen Quartz if:

  • You want a 7-year warranty and plan to stay put
  • Finish matters — you're choosing from eleven colours, not one
  • You're on Intelligent Octopus Go and want native integration without an Ohme

For most buyers, the EO Mini Pro 3 is the better purchase. It's £145 cheaper, OZEV-approved, and functionally equivalent for the nightly charge-and-forget routine most people run. The Quartz is a nicer object with a longer guarantee — but £695 for a 7.2kW charger is a lot to pay for aesthetics when the Tesla Wall Connector does the same electrical job for £478. If neither of these quite fits, the EO vs Tesla comparison is worth a look — particularly for homeowners who don't need the grant.

FAQ

Frequently asked questions.

Not confirmed on the current eligible-chargepoint list. The £500 grant is not guaranteed for the Quartz, so check before ordering. The EO Mini Pro 3 is OZEV-approved.
The EO app supports tariff presets for Octopus Go and others, but it lacks direct Intelligent Octopus Go integration. The Andersen Quartz added that integration in September 2025.
The EO measures 215 × 140 × 100 mm and weighs around 2.5 kg. The Quartz is 286 × 172 × 110 mm at 3.4–5.2 kg — noticeably larger, though still compact by market standards.
The Andersen Quartz comes with a 7-year warranty. The EO Mini Pro 3 offers 3 years — the market average but less than half the Quartz's cover.
