The £124 between a current product and a discontinued one

The numbers look straightforward. The EVEC VEC03 costs £349. The Cord Zero costs £473. Both deliver 7.4 kW on a single-phase supply, both carry Type 2 tethered cables, both pack built-in RCD and PEN fault protection so your installer can skip the separate consumer-unit components. On paper, the VEC03 saves you £124 and does the same job.

On paper is the problem. The VEC03 has been superseded by EVEC's own vecGO 2.0 — what remains is run-out stock, sold under a banner advertising its replacement. The Cord Zero is a current, actively developed product with 4G failover connectivity and direct hooks into the UK's main EV tariffs. That £124 gap is not a like-for-like saving. It is the distance between a charger with a future and one without.

Why connectivity matters more than the spec sheet suggests

A home charger's value sits almost entirely in its software. The hardware charges your car at 7.4 kW either way — the difference is whether the charger can reliably talk to your tariff, your app, and your grid.

The Cord Zero connects over both Wi-Fi and a built-in multi-network 4G SIM with automatic failover. If your home broadband drops at 2 a.m., the charger switches to cellular and your scheduled session runs as planned. The VEC03 relies on Wi-Fi and Bluetooth only. Customer complaints about the EVEC app's reliability — intermittent scheduling, dropped connections — recur often enough to be a pattern rather than a handful of bad reviews. A charger that misses its off-peak window even once a month starts eroding the savings a cheap unit price was supposed to deliver.

The tariff integration gap is wider still. The Cord Zero has direct compatibility with Octopus Go, Octopus Intelligent Go, OVO Charge Anytime, British Gas EV Power, and EDF GoElectric. Set it, and the charger schedules around your rate automatically. The VEC03 has no smart-tariff API at all — not Intelligent Go, not OVO, not anything. You are left setting manual timers through an app with a known reliability issue. On a variable tariff like Octopus Agile, the VEC03 cannot chase half-hourly rates; the Cord Zero can.

The run-out stock question

Buying a discontinued charger is not inherently foolish — some end-of-line products are bargains. The question is whether the software will keep working after the manufacturer moves on. EVEC's attention is now on the vecGO 2.0. The VEC03's OCPP 1.6J support means you could, in theory, migrate to a third-party back-end like Monta if EVEC's own cloud deteriorates. That is a reasonable safety net. But it is also an extra step, an extra account, and an admission that the charger's native software is not the long-term plan.

The Cord Zero, by contrast, is the product Cord is actively selling and updating. Its promotional five-year warranty extension — if still running when you buy — doubles the standard three-year cover at no extra cost. The VEC03's three-year warranty is fine, but a warranty is only as useful as the company's willingness to honour it on a product they have publicly replaced.

The install cost picture

Both chargers include built-in RCD and PEN fault protection, which shaves roughly £100–£150 off a typical installation by removing the need for a separate consumer-unit device. The Cord Zero's fuller safety suite — adding SPD and overvoltage protection — can push that saving higher, to £150–£250 according to Cord's own figures. Typical install costs land at £400–£500 for the Cord Zero and £350–£550 for the VEC03. The installed gap between the two may be narrower than the £124 headline suggests.

For grant-eligible buyers — renters and flat owners — the £500 OZEV grant covers the VEC03's £349 unit price outright and puts the remainder toward installation. It does the same for the Cord Zero, wiping out the £473 unit cost and contributing to the install bill. Either way, the grant makes both chargers close to free on the hardware; the Cord Zero's better software and connectivity become the real differentiator at that point.

The verdict

Buy the Cord Zero if:

  • You are on, or plan to join, any UK smart EV tariff — it integrates directly where the VEC03 cannot
  • Your charger location is more than a wall's thickness from your router, or your broadband is unreliable — 4G failover removes the variable
  • You want a product that is actively supported and updated, not end-of-line stock

Buy the EVEC VEC03 if:

  • You are on a flat-rate electricity tariff with no off-peak window to optimise
  • Your Wi-Fi signal is strong and stable at the charger location
  • You want the lowest possible upfront cost and accept the trade-offs of a discontinued model

The Cord Zero is the charger to put on a wall. The £124 premium buys 4G backup, tariff intelligence, and a product its manufacturer is still investing in — three things the VEC03 cannot match. If budget is the overriding constraint and you have no interest in smart-tariff savings, the VEC03 does the basic job. But for anyone on Octopus Go, Intelligent Go, or any variable rate, the Cord Zero pays its premium back in reliability alone. Spend the extra £124.
