Andersen A3 vs Zaptec Go 2: design or the V2G bet?

£495 for a hidden cable, or £500 for a bet on the future

These two don't share a buyer. The Andersen A3 is £995 because it looks like furniture; the Zaptec Go 2 is £500 because it's quietly certified for a grid service that may or may not materialise. Neither is trying to be the sensible middle choice — that territory belongs to the Hypervolt Home 3 Pro and the Ohme Home Pro.

The shortest version:

• Andersen A3 — the charger you buy when the wall matters. Anodised aluminium, hidden cable, seven-year warranty, £995.
• Zaptec Go 2 — V2G-ready, MID-metered, free 4G, £500. Everyday competent; the real pitch is what comes later.

What you're actually paying for

The Andersen A3's £995 doesn't buy faster charging. Both units top out at 7.4kW on single-phase, which is all most UK homes can deliver anyway. What £995 buys is 247 colour and finish combinations, an anodised aluminium front, and a cable that retracts inside the unit when you're not charging. No other home charger in the UK does that last trick. If your charger hangs on a Victorian terrace frontage or a cedar-clad garage door, that matters. If it lives inside a garage nobody sees, it absolutely does not.

The Zaptec Go 2 spends its £500 on different things. There's a MID-approved energy meter — legally certified readings, useful if you're claiming mileage back from an employer. There's 4G built in with no subscription, which quietly sidesteps the dropped-Wi-Fi problem that plagues cheaper units. There's three-phase auto-switching up to 22kW, unused by 95% of UK buyers but free if you're in the 5%. And there's the V2G certification, which is either the headline act or a footnote depending on your view of the next five years.

The A3's design premium, examined

£495 more than the Zaptec. That's a serious sum, and the honest test is whether anyone will ever see the charger. An Andersen mounted in a dim garage is a waste of good aluminium — the Tesla Wall Connector at £478 or the Easee One at £405 will do the electrical job without complaint, and nobody's judging your garage wall.

Where the A3 earns its money is on a visible elevation. Most chargers look like white plastic rectangles stuck to brickwork. The A3 doesn't. If you spent real money on the house, spending real money on the one piece of tech bolted to its façade is consistent, not indulgent. Just note the 5.5-metre hidden cable — non-negotiable, no longer option — so the mount has to sit within reach of your car's charge port. On awkward driveways, measure twice.

The Zaptec's V2G bet, examined

V2G — vehicle-to-grid — lets a parked EV push electricity back to your house or the grid for money. In April 2026, the UK has a handful of pilot tariffs and a small pool of compatible cars. The Zaptec Go 2 is certified ready; the question is when the ecosystem catches up.

If you keep cars for three or four years, the bet looks thin. If you keep them for eight, or you're buying the charger for the house rather than the current car, it looks better. The Indra Smart PRO is the closer philosophical rival here at £599 — also V2G-minded, with a longer UK track record — and worth a look if the Zaptec's app has put you off. Either way, the Go 2's smart-tariff handling today is competent rather than clever; buyers who want the tariff side automated properly should read across to the Ohme Home Pro, which actually chases Octopus Agile half-hour by half-hour.

The verdict

Buy the Andersen A3 if:

• The charger will be visible from the street or a used outdoor space
• You value finish and materials more than software cleverness
• You're staying in the house long enough to amortise £995 against seven years of warranty

Buy the Zaptec Go 2 if:

• You believe V2G will arrive within the charger's lifetime
• You need MID-certified readings for expense claims or employer reimbursement
• You have three-phase supply and want the 22kW option at £500

On most UK walls, the Zaptec is the more rational £500. But rational isn't why anyone buys an Andersen. If the charger is visible, spend the £995 and don't second-guess it; if it isn't, the Zaptec wins on substance, and the £495 saved buys a lot of off-peak electricity on Octopus Intelligent Go.
