Zaptec Go 2 vs Andersen Quartz

> V2G boundary: A “V2G-ready” label or ISO 15118 support does not by itself provide bidirectional power conversion, export approval or a live energy service. Confirm the compatible car, genuinely bidirectional hardware, certified complete system, installer, service and network approval before assigning value to the claim. Read the UK V2G explainer.

£34 apart, entirely different bets

The Zaptec Go 2 costs £638. The Andersen Quartz costs £672. That £34 gap is almost a rounding error — and yet these two chargers could hardly be less alike in what they prioritise.

The Zaptec is an engineer's charger: marketed as V2G-ready, MID-approved metering, subscription-free 4G, OCPP 1.6J compliance, 3.2 kg of future-facing hardware in a plain white box. The Andersen is a designer's charger: eleven standard finishes, optional Accoya and carbon inserts, IP65 weatherproofing, a seven-year warranty, and the kind of quiet good looks that justify mounting it on the front of a house rather than hiding it down a side passage.

• Zaptec Go 2 — ISO 15118 communication support, MID meter, free 4G. A bet on where home energy is heading.
• Andersen Quartz — Seven-year warranty, eleven finishes, IP65. A bet on the charger you'll still be happy with in 2033.

What V2G-readiness actually buys you today

The Zaptec Go 2 is marketed as V2G-ready because it publishes ISO 15118 communication support, but Zaptec says it cannot currently be registered as a UK V2G installation. That is a genuine technical distinction — and, for now, a largely theoretical one. V2G services in the UK remain thin. The infrastructure is building, the tariffs are forming, but a buyer installing a charger this week is paying for a capability that may not pay back for years.

What does pay back today: the MID-approved energy meter. If you charge a company car at home and reclaim electricity costs, a legally certified meter saves arguments with HMRC. The built-in 4G — subscription-free — means the charger stays connected even if your home Wi-Fi doesn't reach the driveway. And OCPP 1.6J compliance lets the Go 2 talk to third-party energy management systems, which matters if you're building a home battery or solar setup around open protocols rather than a single brand's app.

If V2G scepticism runs deep, the Indra Smart PRO at £395 offers a different V2G pathway for considerably less — that comparison is covered in detail on the Zaptec Go 2 vs Indra Smart PRO page.

The Andersen Quartz as the sensible middle ground

The Quartz exists because the Andersen A3 at £900 is a lot to spend on a charger, and Andersen knows it. Strip the hidden cable drum, keep the finishes, keep the seven-year warranty, keep the IP65 rating — and you land at £672. That is still £197 more than a Tesla Wall Connector doing the same 7.2kW electrical job, but the Tesla doesn't come in satin charcoal or with a CT clamp for solar diversion included in the box.

The Quartz's smart-tariff credentials improved in late 2025 with Intelligent Octopus Go and OVO Charge Anytime integration. That covers the two most popular managed-charging tariffs. It does not cover half-hourly variable rates like Octopus Agile — for that, the Ohme Home Pro at £539 remains the obvious choice, and it's £133 cheaper.

One caution: the Andersen Quartz is not confirmed on the current OZEV-approved chargepoint list. The Zaptec Go 2 is. For eligible renters and flat owners, that £500 grant makes a material difference — it covers a large share of the Zaptec's £638 price and contributes meaningfully to install costs. If you qualify, verify the Quartz's status before committing.

Warranty and weatherproofing

Seven years from Andersen against five from Zaptec. Both are above the three-year industry norm, but the Quartz's cover is notably long — matched in the catalogue only by the Andersen A3 and the Simpson & Partners Home 7 at ten years.

IP65 on the Quartz versus IP54 on the Go 2. The difference matters on an exposed, rain-lashed west-facing wall. It matters less in a sheltered carport. Both will survive a British winter, but the Andersen is rated for it with more margin.

Which to buy

Buy the Zaptec Go 2 if:

• You want V2G-readiness and believe the technology will mature within five years
• You need a MID-approved meter for company-car reimbursement or landlord billing
• You qualify for the OZEV grant — the £500 takes a serious bite out of £638

Buy the Andersen Quartz if:

• Finish matters — you want a charger that looks deliberate, not industrial
• A seven-year warranty and IP65 rating suit an exposed or prominent mounting position
• You're on Intelligent Octopus Go or OVO Charge Anytime and want native integration without an Ohme

For most buyers at this price point, the Zaptec Go 2 offers more functional substance per pound — the MID meter and 4G earn their keep regardless of V2G's timeline. The Andersen Quartz earns its £34 premium only if you value the aesthetics and the longer warranty enough to pay for them. If neither charger's particular strength appeals, the Hypervolt Home 3 Pro at £625 is a capable all-rounder that undercuts both.
