Tesla Wall Connector (Gen 3) vs Andersen A3

The £425 question: function or kerb appeal

The Tesla Wall Connector costs £475. The Andersen A3 costs £900. Both plug into a single-phase supply and deliver 7.4kW — enough to add roughly 30 miles of range per hour to any Type 2 EV. The £425 gap buys no extra speed. What it buys is aluminium, a hidden cable, and the confidence that the thing on your wall looks deliberate rather than bolted on.

• Tesla Wall Connector — £475, 7.3-metre cable, four-year warranty. The sensible default for Tesla owners, and perfectly competent for anyone else.
• Andersen A3 — £900, 5.5-metre hidden cable, seven-year warranty, 247 finish combinations. A charger you choose because you care what the front of your house looks like.

What the Andersen's £425 premium actually contains

Strip away the marketing and the premium breaks into three tangible things.

First, materials. The A3's front panel is anodised aluminium — not painted plastic. It comes in 247 colour and finish combinations, including wood inlays and bespoke colour-matching. No other home charger offers this. The Tesla is a white plastic slab. Perfectly fine tucked beside the garage door; less fine centred on a Georgian brick facade.

Second, the cable disappears. The A3's 5.5-metre tethered cable retracts inside the unit when not in use. Every other charger on the market, the Tesla included, leaves a cable looped on a hook or dangling. For a front-of-house installation, this is a genuine practical difference — no cable sagging, no cable weathering, no cable in the way of the bins.

Third, warranty. The A3 carries seven years; the Tesla, four. Three extra years of cover on a £900 unit is reasonable. On a £475 unit, four years is also reasonable. Neither is a bad deal — but if longevity keeps you awake, the Andersen wins on paper.

What the premium does not contain: better software. The Andersen app handles scheduling and supports Intelligent Octopus Go and OVO Charge Anytime directly, which is more than the Tesla manages on variable rates. But the smart features are competent, not exceptional. If tariff optimisation is the priority, the Ohme Home Pro at £539 does more for less than either charger here.

Cable length and the OZEV grant — two practical wrinkles

The Tesla's 7.3-metre cable is the longest in the UK residential market. The Andersen's hidden cable is 5.5 metres, and there is no option to extend it. If your parking spot sits more than about four metres from the mounting wall, the A3 may not reach. Measure first.

Then there is the grant. The Andersen A3 is OZEV-approved; the Tesla Wall Connector is not. Eligible renters and flat owners can claim the £500 OZEV grant on the A3, which drops the effective unit cost to £400 — suddenly £75 less than the Tesla. For that specific buyer, the economics invert entirely. The Tesla owner who rents and qualifies for the grant should look hard at the A3, or at any other OZEV-approved charger in the catalogue. The Easee One at £489, for instance, has the grant cover the unit outright and chip into the install too.

Where the Tesla still makes sense

The Tesla Wall Connector integrates natively with the Tesla app — charge history, scheduling, power sharing across up to six units on one circuit. If you own a Tesla and park in a garage or on a side wall nobody sees, the case for the A3 evaporates. You save £425, get a longer cable, and the app is already on your phone.

The Tesla also offers a 22kW three-phase option. Fewer than one in twenty UK homes have three-phase, but if yours does, the Andersen cannot match it — the A3 is single-phase only.

For buyers on Octopus Agile, neither charger is ideal. Both lack the ability to chase half-hourly rate changes automatically. That job belongs to the Ohme Home Pro — and the comparison between it and the Tesla is covered in more detail on the Tesla Wall Connector vs Ohme Home Pro page.

The verdict

Buy the Tesla Wall Connector if:

• The charger sits in a garage, carport, or side wall out of public view
• You want the longest cable available — 7.3 metres
• You own a Tesla and value native app integration without paying more for it

Buy the Andersen A3 if:

• The charger mounts on a prominent, street-facing wall and appearance matters
• You qualify for the £500 OZEV grant, which brings the A3 below the Tesla's price
• You want the longest warranty on the UK market — seven years

For most buyers, the Tesla Wall Connector at £475 is the right call. It charges at the same speed, carries a longer cable, and costs £425 less. The Andersen A3 is not overpriced for what it is — it is a piece of exterior design that happens to charge a car. The question is whether your wall deserves it.
