Andersen A3 vs Cord Zero

£427 buys you looks, not kilowatts

The Andersen A3 costs £900. The Cord Zero costs £473. Both deliver 7.4kW to a Type 2 plug. Both are OZEV-approved. Both schedule around cheap overnight rates. The £427 gap is not about charging — it is almost entirely about what the thing looks like bolted to your house.

• Andersen A3 — 247 finishes, hidden cable, anodised aluminium, seven-year warranty. A piece of exterior furniture priced like one.
• Cord Zero — dual Wi-Fi and 4G, built-in safety suite, lower install cost, functional app. The pragmatist's charger.

What the Andersen's £427 actually buys

Start with the cable. The A3's 5.5-metre tethered cable retracts into the body of the unit when you unplug. No other home charger on the UK market does this. If you have a front-of-house driveway and the charger is in plain sight, the difference between a coiled cable dangling from a plastic box and a flush aluminium panel is considerable — and, for some homes, worth defending at planning level.

Then the finish. Andersen offers anodised aluminium fronts, real-wood accent panels, and bespoke colour-matching across 247 combinations. The Cord Zero is a compact white rectangle. Perfectly fine on a garage wall. Less fine next to a Georgian front door.

The warranty is the other tangible gain: seven years, versus the Cord Zero's standard three (currently extended to five under a promotion that may end). Over a long ownership period, that extra cover has real value — though it is worth noting that the Cord's built-in RCD, PEN fault detection, and surge protection mean fewer external components that could fail outside warranty.

What the £427 does not buy is better connectivity, better tariff intelligence, or a cheaper install.

Where the Cord Zero earns its price

Connectivity is the Cord Zero's clearest advantage. It carries both Wi-Fi and a built-in multi-network 4G SIM, with automatic failover. The A3 is Wi-Fi only. If your router sits at the back of the house and the charger sits at the front — a common UK layout — the Cord stays online; the Andersen may not. A charger that drops its connection cannot follow a schedule, and a schedule is the entire point of a smart charger on a cheap overnight tariff.

Install cost widens the gap further. The Cord Zero bundles its own RCD, PEN fault detection, and surge protection inside the unit. On a typical install, that saves £150–£250 in parts and labour. The Andersen needs those components fitted externally. So the real-world gap between the two is closer to £577–£677 once install is counted — unit plus typical install of £400–£500 for the Cord versus £400–£600 for the Andersen, before the parts saving.

Both chargers work with the major EV tariffs. The Cord Zero lists compatibility with Octopus Go, Intelligent Go, OVO Charge Anytime, British Gas EV Power, and EDF GoElectric. The Andersen supports Intelligent Octopus Go and OVO Charge Anytime directly. For broader tariff flexibility, the Cord has the edge — though on the two most popular tariffs (Octopus Go and Intelligent Go), both do the job.

The app gap — and whether it matters

The Cord AI app is functional rather than refined. It does scheduling, energy monitoring, and tariff integration, but the interface feels a generation behind the Ohme Home Pro or Tesla Wall Connector. The Andersen app is in a similar bracket: competent, not exciting. Neither charger wins on software. If app quality is the priority, the Ohme Home Pro at £539 is the better pick — and readers weighing that option against the Cord can find a closer look at the Ohme Home Pro vs Cord Zero comparison.

The verdict

Buy the Andersen A3 if:

• The charger will be visible from the street and kerb appeal matters to your property
• You want the hidden cable — no other charger offers it
• A seven-year warranty justifies the premium over the Cord's three (or promotional five)

Buy the Cord Zero if:

• You want the most reliable connection — dual Wi-Fi and 4G, no signal worries
• You want the lowest total cost, including install savings from the built-in safety suite
• The charger lives on a side wall or in a garage where nobody sees it

For most buyers, the Cord Zero is the right answer. It charges at the same rate, connects more reliably, costs less to buy, costs less to install, and works with more tariffs. The Andersen A3 is a genuinely beautiful object — the only home charger that could reasonably be called furniture — but £427 is a steep price for aesthetics when the electrons arrive at the same speed. If the charger is hidden from view, the decision is already made.
