/5 min read

Buy the Tesla Wall Connector at £478 unless the charger will be visible from the street or from inside the house — in which case the Andersen A3 at £995 is the only one here where design is the actual argument.

The £517 that buys you a hidden cable

Two tethered 7.4kW chargers, one priced at £478 and the other at £995. The Tesla Wall Connector is the cheapest route to the official app, the longest cable in our round-up, and a competent four-year warranty. The Andersen A3 is £517 more for the same electrical work — and the only charger on the UK market that hides its cable inside the unit.

That is the whole comparison. Everything else is commentary.

  • Tesla Wall Connector — £478, 7.3m cable, native Tesla app, four-year warranty. The default for a Tesla owner.
  • Andersen A3 — £995, 5.5m hidden cable, 247 finish options, seven-year warranty. The choice when the wall matters.

Is the Andersen's £517 premium worth it?

Walk to where the charger will live. Stand there. If you can see it from the kitchen window, from the front path, from the neighbour's driveway — the Andersen has a case. Anodised aluminium, wood fascias, bespoke colour matching, cable retracted out of sight. It is the best-looking home charger sold in the UK, and the seven-year warranty is the longest going.

If the charger lives in a garage, behind a gate, or on a side return nobody sees — the £517 is paying for a wall nobody looks at. The Tesla Wall Connector does the same 7.4kW, has a longer cable, and leaves £517 in the bank for a decent tariff.

There is also a quiet practical point. The Andersen's hidden cable tops out at 5.5 metres with no longer option. The Tesla gives you 7.3. If the car parks more than about five metres from the mount — a long drive, a carport set back from the house, a detached garage — the Andersen cannot reach. Check the geometry before you fall for the finish.

Smart features, honestly ranked

Both chargers schedule. Both support smart tariffs. Neither does it best in class.

The Andersen's app handles Octopus Intelligent Go and OVO Charge Anytime, which covers most buyers. The Tesla schedules manually through the app you already have on your phone, and if you drive a Tesla on Intelligent Go, Octopus talks to the car directly through Tesla's API — the charger is not in the conversation. On that tariff the Andersen's smart credentials add exactly nothing.

If you are on Octopus Agile, where rates move every half hour and the charger needs to chase them, neither of these is the right tool. The Ohme Home Pro at £535 does that job for £460 less than the Andersen and is OZEV-approved. That pairing is the better read for Agile users: see the Tesla vs Ohme Home Pro comparison.

Solar owners should look elsewhere too. Neither of these diverts PV natively in the way the Zappi GLO does. The Andersen has solar integration in the marketing copy; Zappi has it in the hardware.

The grant question

The Tesla is not OZEV-approved. The Andersen is. If you rent or own a flat and qualify for the £500 grant, that changes the gap meaningfully — the A3 becomes £495 after grant, the Tesla stays at £478. At near-parity, the Andersen's finish and seven-year warranty are a much easier sell. For homeowners, who don't qualify, the full £517 gap stands.

The verdict

Buy the Tesla Wall Connector (Gen 3) if:

  • You drive a Tesla and want the cheapest route to the native app
  • The charger lives somewhere nobody sees
  • You need more than 5.5 metres of cable reach

Buy the Andersen A3 if:

  • The charger is visible from the street, the front of the house or a shared drive
  • You want the longest warranty on the UK market (seven years)
  • You qualify for the OZEV grant, which closes most of the price gap

On a wall that matters, the Andersen is the only charger here that justifies itself on looks alone. On every other wall, the Tesla is £517 better spent. Most driveways are the second kind.

FAQ

Frequently asked questions.

Only if the wall it sits on matters to you. Electrically the two do the same 7.4kW job; the Andersen buys you a hidden cable, 247 finish options and a seven-year warranty, not faster or cheaper charging.
Yes — the A3 is OZEV-approved, so eligible renters and flat owners can claim £500 off. The Tesla Wall Connector is not approved and does not qualify.
No. The A3's hidden cable is 5.5 metres with no longer option; the Tesla's is 7.3 metres. If the car parks more than five metres from the mount, the Tesla is the only one of the two that reaches.
The Tesla Wall Connector, comfortably. Intelligent Go already schedules charging through Tesla's API, so the Andersen's smart-tariff features add nothing you don't already have — and you save £517.
