Price & Value
The Tesla Wall Connector (Gen 3) is £232 cheaper at £475 compared to the Zaptec Go 2 at £707.
When you factor in professional installation (typically £400–£600), the total installed cost for the Tesla Wall Connector (Gen 3) is approximately £875–£1075, while the Zaptec Go 2 comes in at around £1107–£1307. Fully installed, the Tesla Wall Connector (Gen 3) remains the more affordable option.
If you're eligible for the OZEV grant (available to renters and flat owners), you can claim £350 off the installation cost. That would bring the effective unit-plus-install price down to roughly £525–£725 for the Tesla Wall Connector (Gen 3) and £757–£957 for the Zaptec Go 2. Both chargers are OZEV-approved, so eligibility depends on your living situation rather than the charger itself.
While the Zaptec Go 2 costs more up front, it comes with 6 smart features compared to the Tesla Wall Connector (Gen 3)'s 5. The extra £232 buys you additional functionality that could save money long-term — particularly if features like smart tariff integration or solar diverting apply to your setup. Whether the premium is justified depends on how many of those extra features you'll actually use.
Power & Charging Speed
Both the Tesla Wall Connector (Gen 3) (7.4kW / 22kW) and Zaptec Go 2 (7.4kW / 22kW) support three-phase charging, offering up to 22kW on a three-phase supply. On a standard UK single-phase supply, both deliver around 7kW — more than enough for overnight charging.
On a standard UK single-phase supply, both will charge a Tesla Model 3 Long Range (75kWh battery) from 20% to 80% in approximately 5–6 hours overnight. Even a Tesla Model Y with its larger battery completes a typical daily top-up well within an overnight window. For the vast majority of UK Tesla owners, single-phase 7kW charging is more than sufficient — you'll wake up to a full battery every morning.
Cable length is an often-overlooked consideration. The Tesla Wall Connector (Gen 3) comes with a 7.3 metres cable, while the Zaptec Go 2 has a Untethered (use own cable) cable. A longer cable gives you more flexibility for driveway positioning — particularly useful if your charger is mounted on a side wall but your Tesla's charge port is on the rear left. Measure your likely cable run before buying to ensure the cable reaches comfortably without being fully stretched.
For most Tesla owners who plug in when they get home, both chargers provide more than enough power for a full overnight charge. The real-world difference between 7kW and 7.4kW is negligible — roughly 20 minutes over a full charge cycle. Unless you have a three-phase supply and regularly need rapid top-ups during the day, charging speed should not be the deciding factor between these two chargers.
Smart Features
The Tesla Wall Connector (Gen 3) offers: Tesla app integration, Scheduled charging, Power sharing (up to 6 units), Wi-Fi connected, OTA updates. The Zaptec Go 2 offers: Zaptec app, Scheduled charging, V2G-ready, MID-approved energy meter, 4G connectivity (subscription-free), OCPP 1.6J compliant.
Breaking these down by category: for connectivity, the Tesla Wall Connector (Gen 3) uses Wi-Fi connected, while the Zaptec Go 2 uses 4G connectivity (subscription-free). For energy management, the Tesla Wall Connector (Gen 3) provides Power sharing (up to 6 units), compared to the Zaptec Go 2's MID-approved energy meter. Solar and scheduling features are covered in the dedicated sections below.
The most meaningful differentiators: the Tesla Wall Connector (Gen 3) uniquely offers Tesla app integration, Power sharing (up to 6 units), Wi-Fi connected, OTA updates, while the Zaptec Go 2 exclusively provides Zaptec app, V2G-ready, MID-approved energy meter, 4G connectivity (subscription-free), OCPP 1.6J compliant. These unique features often determine which charger is the better fit — if a feature on one charger's exclusive list is a must-have for you, that should heavily influence your decision.
The app experience matters as much as the feature list — you'll use it daily. Tesla's app is polished and familiar to Tesla owners, providing a seamless experience alongside vehicle controls. The Zaptec app provides standard charging management features. Both apps are available on iOS and Android, but user reviews suggest the day-to-day experience can vary significantly between brands.
Warranty & Build Quality
The Tesla Wall Connector (Gen 3) comes with a 4 years warranty, while the Zaptec Go 2 offers 5 years. The Zaptec Go 2 offers 1 year more coverage, giving you added peace of mind. Both are OZEV-approved and suitable for outdoor installation — a longer warranty provides more peace of mind for a product that lives outside year-round and is exposed to British weather.
For weatherproofing, the Tesla Wall Connector (Gen 3) is rated IP44 (indoor/outdoor) (protected against solid objects over 1mm and water splashes from all directions), while the Zaptec Go 2 is rated IP54 (weatherproof) (splash-proof — protected against splashing water from any direction). A higher IP rating means better protection against rain, hose water, and dust. In practical terms, any rating of IP54 or above is suitable for a UK outdoor installation, but a higher rating provides extra confidence in extreme weather — particularly relevant if your charger is exposed rather than sheltered under a car port.
Build quality is reflected in the materials and construction. The Tesla Wall Connector (Gen 3) weighs 5.3 kg with dimensions of 353mm × 152mm × 124mm, while the Zaptec Go 2 weighs ~3.2 kg with dimensions of 240mm × 180mm × 106mm. A heavier charger typically indicates more robust construction, though modern chargers use high-quality polycarbonate housings that are both lightweight and impact-resistant. If your charger is in a location where it might get bumped by car doors or footballs, look for IK10 impact resistance in the specs — this is the highest rating and means it can withstand 20 joules of impact (equivalent to a 5kg weight dropped from 40cm).
For extended protection: the Tesla Wall Connector (Gen 3) has one of the longest standard warranties at 4 years, and Tesla's track record for honouring warranty claims is generally well-regarded. The Zaptec Go 2 comes with a standard 5 years warranty from Zaptec. When comparing warranties, also check what's covered — most warranties cover manufacturing defects and component failure, but may not cover damage from incorrect installation or extreme weather events. Having your charger installed by an OZEV-approved installer typically ensures the warranty remains valid.
Which Should You Buy?
Buy the Tesla Wall Connector (Gen 3) if you want the best value for money, or overall quality and user satisfaction matter most, or official tesla charger.
Buy the Zaptec Go 2 if long-term peace of mind is a priority, or v2g-ready.
Our Verdicts
The Tesla Wall Connector is the no-brainer choice if you want the cleanest integration with your Tesla. It's competitively priced, has the longest warranty, and the Tesla app experience is unmatched. The only reason to look elsewhere is if you specifically want smart tariff integration (look at the Ohme) or solar diverting (Wallbox Eco-Smart).
The Zaptec Go 2 is for people who think long-term. V2G technology will eventually transform how we use EVs as mobile power stations, and the Go 2 is ready for that future today. The MID-approved meter and free 4G are nice extras. But if V2G isn't on your radar, the Easee One is a better value untethered option, and the Ohme beats it on smart tariff integration.
