NexBlue Edge — product shot

The NexBlue that does three-phase. Where the Point 2 is a single-phase 7.4 kW home unit, the Edge is a 235 mm square box that accepts anything from a 6 A single-phase feed to 32 A three-phase, so it charges at 22 kW on a three-phase supply and 7.4 kW on a normal one. NexBlue's own datasheet titles it a charger "for commercial scenarios", which is the honest framing: it is a workplace unit that is OZEV-approved for driveways too, and UK resellers sell it at £599 against the Point 2's £486.

Two things to know before reading further. First, the model names are a mess: the UK unit is the "Edge (UK)" (reseller code NB2620A), and the Edge 2 and Edge Max that NexBlue lists on its UK site are newer designs with OCPP 2.0.1, ISO 15118, Ethernet and a five-year warranty that no UK retailer stocks and that are not on the OZEV list. This review covers the one you can buy. Second, it is socket-only; there is no tethered Edge.

Best for: Homes with a three-phase supply, or a driveway that doubles as a small-business car park, where one unit needs to do 22 kW and still talk to Octopus or OVO.

Installation

Fitting the NexBlue Edge.

235 × 230 × 130 mm and 1.9 kg, on a backplate NexBlue says fits in four minutes. IP54 and IK08 — the Point 2 and Edge 2 are IK10. PEN fault protection is built in, so no earth rod. What is not built in is the 30 mA Type A RCD: the datasheet carries 6 mA DC detection and 30 mA AC detection and says an external Type A RCD is required, which means an RCBO at the consumer unit. That is the same arrangement as the Rolec Zura and it adds to the install where the Easee One and Ohme Home Pro carry the RCD inside. Dynamic load balancing and solar-surplus charging both need the separate NexBlue Zen meter, which is not in the box. A standard single-phase fit sits in the £450–£700 band; a new three-phase supply is a DNO job on top. Full walkthrough in our installation guide.

Tariff compatibility

What it costs to run.

Better than its commercial framing suggests. OVO announced in September 2025 that the Edge and Point are compatible with Charge Anytime, and UK resellers report Octopus accepting the Edge for Intelligent Go alongside the Point 2 — run your details through Octopus's eligibility checker before you buy, because Octopus does not publish a list. The myNexBlue app's EcoPilot mode schedules against fixed windows for Octopus Go, EDF GoElectric and the rest. E.ON's charger-led Next Drive Smart list does not include NexBlue. The 4G eSIM is the practical win here: a charger that drops off Wi-Fi drops off the supplier's schedule, and the Edge has a second route. More in our smart-tariff chargers guide.

Compare every tariff

Price

What you actually pay.

The unit is currently £599. £450–£700 is the working installation range, putting a typical installed total at £1,049–£1,299. 22 kW socket-only unit (NB2620A) at UK resellers; UK EV Installers £598.80. NexBlue's RRP is £549 + VAT. Install band allows for the external Type A RCD it needs.

Five-year total

£2,260

Charger, installation, and five years of electricity on Octopus Intelligent Go, at 10,000 miles a year.

Less £500 if you qualify for the OZEV grant.

Against the field

How it compares.

Against the NexBlue Point 2: the Point 2 has OCPP 2.0.1, ISO 15118, a tethered option, IK10 and five years of warranty for £113 less; the Edge has 22 kW, 4G and the RFID reader. On a single-phase supply the Point 2 is the better NexBlue. Against the Easee Charge Max, the other 22 kW socket here: the Easee has a MID meter, a built-in RCD and a five-year warranty for £276 more, but no Octopus or OVO link at all. Against the myenergi zappi 22 kW: the zappi has native solar diversion and the broadest tariff support, at a higher price. The Edge is the cheap route to 22 kW that still does smart tariffs.

Cross-shopped with

What we loved

  • PlusOne unit covers 7.4 kW single-phase and 22 kW three-phase, so a future supply upgrade doesn't mean a new charger
  • PlusBuilt-in 4G eSIM plus Wi-Fi and Bluetooth — keeps the supplier schedule running when the Wi-Fi drops
  • PlusOVO Charge Anytime compatible (OVO's own announcement) and reported on Octopus's Intelligent Go checker
  • PlusOZEV-approved for both home and workplace grants; PEN fault protection built in, no earth rod
  • PlusBackplate install, RFID card in the box, local OCPP 1.6J for third-party platforms
  • Plus£276 cheaper than the Easee Charge Max for the same 22 kW

What we didn't

  • MinusSocket only, no tethered version — budget for a cable
  • MinusThree-year warranty and IK08 where the Point 2 gets five years and IK10
  • MinusExternal 30 mA Type A RCD required, which adds to the install; the Zen for load balancing or solar is extra too
  • MinusOCPP 1.6J only, no ISO 15118 — the Edge 2 that fixes this isn't sold in the UK yet
  • MinusConfusing model names (Edge, Edge 2, Edge Max) and a tiny UK review base
  • MinusNo Ethernet port
