Sync Energy Wall Charger 2 vs Andersen Quartz: £333 for a prettier box?

£333 buys a finish, not a faster charge

The Sync Energy Wall Charger 2 costs £362. The Andersen Quartz costs £695. Both deliver roughly 7kW to a single-phase home. Both include solar diversion via CT clamp. Both have built-in PEN fault protection. The gap between them is not about what they *do* — it is about how long they are guaranteed to do it, and how good they look while doing it.

• Sync Energy Wall Charger 2 — £362, 7.4kW, 7.5m cable, three-year warranty, OZEV-approved, nine fascia colours.
• Andersen Quartz — £695, 7.2kW, 5.5m cable (8.5m for £99 extra), seven-year warranty, OZEV approval unconfirmed, eleven finishes plus Accoya and carbon inserts.

The grant question tilts the maths further

The Sync Energy is OZEV-approved. For eligible renters and flat owners, the £500 grant covers the £362 unit outright and chips into the install costs too. The Andersen Quartz does not have confirmed OZEV approval. That means a qualifying buyer could be looking at a total outlay difference well north of £333 once the grant is factored in — potentially closer to £800 separating an installed Sync Energy from an installed Quartz, given Andersen's own installation pricing tends to run above the generic £300–£600 range.

If you are not grant-eligible — most homeowners are not — the comparison is cleaner: £362 versus £695, same basic job, different packaging.

Where the Sync Energy gives more for less

The Sync Energy's 7.5-metre tethered cable is the longest on any home charger we track — longer than the Tesla Wall Connector's 7.3m, and a full two metres longer than the Quartz's standard 5.5m. If your parking spot is any distance from the consumer unit, that matters. Matching it on the Quartz means paying the £99 8.5m cable upgrade, pushing the Andersen to £794.

Smart features favour the Sync Energy too. It supports OCPP 1.6J, dynamic load balancing, Ethernet alongside Wi-Fi, and TariffSense scheduling. The Quartz has Intelligent Octopus Go and OVO Charge Anytime integration — useful, but narrower. Neither charger is a tariff-automation leader in the way the Ohme Home Pro is; on half-hourly tariffs like Octopus Agile, neither will chase slot-by-slot pricing for you. But for fixed off-peak windows — Octopus Go, E.ON Next Drive, British Gas Electric Drivers — both schedule competently.

The Sync Energy's caveats are real. Wi-Fi reliability has drawn mixed reports; if your charger is far from the router, the 4G variant is worth specifying. The app platform changed early on, which left some buyers confused. And the installer network is smaller than the big names. None of these are deal-breakers, but they are the kind of rough edges you accept at £362.

Where the Andersen Quartz earns its premium

Two things. First: the seven-year warranty, matched in this price bracket only by the Andersen A3 and the Simpson & Partners Home 7. The Sync Energy's three years is average. A charger bolted to an outside wall for a decade will face weather, UV, and the odd bump from a wheelie bin. Seven years of cover has a tangible value — though whether it is worth £333 depends on your appetite for risk.

Second: the finish. Eleven colours, optional Accoya wood and carbon-fibre inserts, a compact 286 × 172 × 110mm body. The Quartz exists because Andersen understood that some people care what a box on their house looks like. The Sync Energy offers nine interchangeable fascia plates — not bad — but the materials and detailing are not in the same league. If your charger faces the street and you have strong feelings about kerb appeal, the Quartz is one of the few units that does not look like an electrical panel.

Everything else — IP65 weatherproofing, PEN fault detection, solar diversion — is a draw.

The verdict

Buy the Sync Energy Wall Charger 2 if:

• You want the most charger for the least money — £362 for 7.4kW, 7.5m cable, solar diversion, and OZEV eligibility
• You are a grant-eligible renter or flat owner, where the £500 covers the unit and part of the install
• Cable length matters — 7.5m standard, no upgrade fee

Buy the Andersen Quartz if:

• A seven-year warranty is a priority and you want long-term peace of mind
• Aesthetics are non-negotiable — you want a charger that looks considered, not just functional
• You are already in the Andersen ecosystem or plan to use Intelligent Octopus Go or OVO Charge Anytime integration

For most buyers, the Sync Energy is the rational pick. It charges fractionally faster, cables further, costs £333 less, and qualifies for the grant. The Andersen Quartz is the charger you buy when you have already decided you want an Andersen — and at £695, it is the more affordable way to get one. But £333 is a lot to pay for a longer warranty and a nicer fascia. If the budget matters at all, the Sync Energy goes on the wall.
