Function or Form? What This Comparison Really Comes Down To
These two chargers could not have more different priorities. The Ohme Home Pro is an engineer's charger — modest-looking, packed with software smarts, and laser-focused on cutting your electricity bill. The Andersen A3 is a designer's charger — 247 colour and finish combinations, a hidden cable system, and the kind of build quality that makes visitors ask about it. Both deliver 7.4kW to your Tesla. The gap is everything else.
In a nutshell:
- Ohme Home Pro: The money-saver. Best-in-class smart tariff integration at £535, with built-in 4G and solar diverting.
- Andersen A3: The head-turner. Anodised aluminium, hidden cables, 7-year warranty, and a £995 price tag to match.
Is the Andersen A3's Design Worth £460 More?
Let's not dance around the number. The Andersen A3 costs £995 before installation. The Ohme Home Pro costs £535 — or £999 with standard installation included. So you could have an Ohme fully installed on your wall for roughly the same price as an Andersen unit sitting in its box.
What does that premium buy you? Genuinely beautiful hardware. The anodised aluminium body comes in combinations of metals, woods, and custom colours that no other charger can touch. The hidden cable system tucks the 5.5m lead away inside the unit when you're not using it, leaving a clean, uncluttered wall. If your charger sits beside your front door or on a visible wall in the driveway, the Andersen makes every other charger look like a white plastic box — because that's what most of them are.
But if your charger lives in a garage or down the side of the house where nobody sees it, you're spending £460 on aesthetics with no audience. That money would cover roughly 6,500 kWh of off-peak electricity — over a year's worth of Tesla charging for most drivers.
Smart Tariff Savings: The Ohme's Strongest Card
This is where the Ohme pulls away decisively. Both chargers support Octopus Intelligent Go and OVO Charge Anytime, but the Ohme is officially recommended by Octopus Energy and integrates directly with your tariff provider. It automatically finds the cheapest half-hour slots and schedules your charge across them — no manual scheduling, no fiddling.
The Andersen handles smart tariff scheduling through its app, and it works, but it's not the primary focus of the product. The Ohme's entire identity is built around saving you money per kWh. If you're on a smart tariff — or planning to switch to one — the Ohme will likely recoup its purchase price faster than any other charger on the market.
The Ohme also has built-in 4G with a three-year SIM included, so it stays connected even if your Wi-Fi is patchy at the charging point. The Andersen is Wi-Fi only. If your charger is at the far end of the driveway, that could be a real headache.
Warranty and Build: Where the Andersen Fights Back
The Andersen A3's 7-year warranty is exceptional — more than double the Ohme's 3 years and the longest you'll find on any UK home charger. That's a statement of confidence in the hardware, and the anodised aluminium construction backs it up. At 7.5 kg, it feels substantial in a way the 3.5 kg Ohme simply doesn't.
The Andersen also carries a higher IP54 weatherproof rating versus the Ohme's IP65 — actually, here the Ohme wins. IP65 means full protection against water jets from any direction, while IP54 protects against splashing water only. For an outdoor-mounted charger in the UK, that difference matters. It's a slightly odd trade-off: the charger that looks more premium is technically less weatherproof.
Solar Households Should Lean Towards the Ohme
If you have solar panels, both chargers offer integration, but the Ohme Home Pro has dedicated solar diverting built in. It can direct surplus generation into your car automatically, reducing grid reliance. Our guide to the best EV chargers for solar covers this in more detail, but the Ohme's combination of solar diverting and smart tariff optimisation makes it the stronger choice for anyone trying to minimise running costs.
Which Should You Buy?
Buy the Ohme Home Pro if:
- You want the lowest possible running costs via smart tariff automation
- Your charger is in a garage, carport, or anywhere aesthetics don't matter
- You have solar panels and want built-in diverting
- You'd rather spend £460 on electricity than on aluminium finishes
Buy the Andersen A3 if:
- Your charger is prominently visible and you want it to complement your home
- You value a 7-year warranty and premium build materials
- You're less concerned about squeezing every penny from your energy tariff
- The hidden cable system appeals — no dangling lead on your wall
For the majority of Tesla owners, the Ohme Home Pro is the better buy. It costs less, saves more, and does the job that actually matters — putting cheap electricity into your car — better than almost anything else. The Andersen A3 is a lovely object, and if your home's kerb appeal is important to you, it's the only charger that truly delivers on design. But lovely objects don't reduce your energy bill. The Ohme does. Check our best Tesla home charger guide for how both stack up against the wider field.
