Hive EV Charger Review: Solid Kit, One Smart Catch
British Gas’s home charger — now the Sync Energy 2 — nails the hardware: the longest cable in its class, connectivity that won’t drop, solar built in. The honest verdict on price, the Octopus question, and where it trails the best.
The short answer
The Hive EV charger — now the Sync Energy 2 — is dependable, weatherproof hardware with two genuine standouts: the 7.5-metre tethered cable (the longest fitted as standard in its class) and dual Wi-Fi + 4G connectivity that keeps it online even where broadband is weak. It’s British Gas’s home charger: 7.4kW, now with built-in solar diversion, and — for British Gas electricity customers — 25% off charging via Power+ mode. Installed from around £1,019, unit alone ~£400–£549.
The honest catches: a 3-year warranty that’s shorter than several rivals’ 5–7, and manual scheduling unless you pair it with a smart tariff — it’s not as effortlessly hands-off as Octopus’s own charger. Two myths to clear up: it does now work with Intelligent Octopus Go (since late 2025 — older reviews are stale), and the “keeps going offline” complaints belong to the old Alfen-based units, not this one. We score it 4.1/5. Full spec, pricing and rivals below.
What this review covers
The Hive EV charger is one of the most-searched chargers in Britain — partly because it carries the British Gas name, partly because there’s genuine confusion about what it is, whether it works with Octopus, and why older reviews complain about it dropping offline. This review clears all of that up: what today’s charger actually is, what it does brilliantly, where it falls short, and who should buy it.
What the Hive charger actually is (and the model confusion)
Hive is British Gas’s smart-home brand (owned by Centrica), and the Hive EV charger is the unit British Gas fits through its home charging service. The important clarification, because it explains a lot of contradictory information online: there have been two generations. The older Hive charger was a rebadged Alfen Eve S-Line — a capable but basic unit, GPRS-connected, with no solar support, and the source of most of the “offline” grumbles you’ll find on forums. The current model is the Hive Sync Energy 2 (properly, the Sync Energy Wall Charger 2): a modern 7.4kW tethered charger with solar diversion, long cable, dual connectivity and app control. When this review says “the Hive charger,” it means the current Sync Energy 2 — and where the old Alfen unit matters (mainly the offline issue), we’ll say so. Note too that this is a review of the charger itself; the British Gas EV charger review covers the install-package side — the survey, the labour, what changes your quote.
What’s genuinely good
The cable. At 7.5 metres, the Sync Energy 2’s tethered cable is the longest fitted as standard in its class — most rivals ship 5m — and it’s the quiet hero of the whole unit. If your charge port and parking spot don’t line up (and they often don’t), that extra reach is the difference between convenient and infuriating, every single day. The connectivity. Dual Wi-Fi plus 4G means that when your home broadband wobbles — likely, for a box on an outside wall at the far end of the drive — the charger stays online via cellular. It’s more useful than it sounds, and it directly answers the old units’ biggest weakness. The build. IP65 weatherproofing and IK10 impact resistance make it genuinely happy on an exposed wall, and built-in PEN fault protection removes the need for a separate earth rod, typically saving £50–£100 on installation. Nice touches: nine interchangeable fascia colours (swappable after fitting), OCPP 1.6J support for third-party energy platforms, and — the practical one — built-in solar diversion, covered below. This is well-sorted hardware.
Real 2026 pricing
| What | Typical 2026 price |
|---|---|
| Sync Energy 2 unit only | ~£400–£549 |
| Fully installed (via British Gas, from) | ~£1,019 |
| Installation element (standard) | ~£460–£900 |
| British Gas Power+ charging saving | −25% on charging |
| OZEV grant (renters/flats only) | −£350 |
The installed “from” price assumes a standard install — up to ~15m of cable run, a brick or rendered wall, no consumer-unit upgrade — so older or awkward properties pay more, and the pre-install survey gives the firm number before you commit. Two things sweeten the value: you don’t need to be a British Gas energy customer to have one fitted (and some independent OZEV-approved installers fit it too), while if you are a British Gas electricity customer, Power+ mode gives 25% off your electricity every time you charge — a recurring saving that meaningfully shifts the lifetime cost. On grants, the picture is the standard 2026 one: no grant for homeowners with a driveway, but renters and flat-dwellers can claim up to £350 (the full context is in our 7kW charger guide).
The Octopus question — myth-busted
This is the most-muddled point about the Hive charger, so plainly: yes, the Sync Energy 2 works with Intelligent Octopus Go. Since late 2025 it’s been on Octopus’s approved list for IOG, meaning Octopus can schedule your charging automatically into the cheapest overnight slots and the guaranteed off-peak window — the same smart benefit as chargers costing far more. Any review saying the Hive “doesn’t do Intelligent Octopus Go” is out of date. Separately, the charger’s own app (via its TariffSense feature) directly handles Octopus Go and other fixed-window tariffs — set the cheap window, charging runs within it. The one real limitation: it doesn’t read Octopus Agile’s half-hourly prices, so committed Agile tracker users are still better with an Ohme Home Pro. But for everyone on Intelligent Octopus Go, Octopus Go or a British Gas EV tariff — the overwhelming majority — the Hive charges cheaply and smartly, with the British Gas 25% Power+ saving stacking on top for their customers.
The “offline” problem, explained (and fixed)
Why older Hive reviews complain about connectivity — and why it no longer applies
Search the Hive charger and you’ll hit forum threads about units going “offline,” flashing lights and connectivity headaches. Here’s the honest context: those complaints are about the older rebadged Alfen Eve S-Line chargers, which relied on GPRS cellular through a separate “Matt:e” earthing device — a setup that genuinely did drop offline and confuse owners. The current Sync Energy 2 was engineered specifically to solve this, with dual Wi-Fi + 4G so that if one connection fails the other holds the charger online. It’s the reason connectivity is now a strength, not a weakness. So: if you already own an older Hive/Alfen unit that keeps dropping, the usual fixes are power-cycling the charger and its earthing device and checking the connection — our EV charger troubleshooting guide walks through it. If you’re buying new, the single biggest complaint in the old reviews has essentially been designed out. It’s a genuinely reassuring case of a manufacturer fixing its predecessor’s worst flaw.
The honest catches
Three deductions keep this from a higher score. The warranty: 3 years with installation (2 without) is shorter than the 5–7 years several rivals offer — not alarming for a well-built unit, but a genuine gap on paper and the clearest place the Hive trails. The smart scheduling: it’s manual unless paired with a smart tariff — set-and-forget automation exists via IOG or TariffSense, but out of the box it’s less effortlessly hands-off than Octopus’s own charger, which bakes scheduling in. The app: capable and clear, but not the class-leading smart experience of the Ohme — fine for most, a slight step behind for tariff enthusiasts. And a minor install note: there’s no built-in RCD, so a Type A RCD goes in at the consumer unit (routine, but a line item). None of these is a dealbreaker; together they place the Hive as a strong hardware choice that gives a little ground on smarts and cover.
Hive vs Ohme vs Octopus Charge
Three good chargers, three different strengths. Hive Sync Energy 2 wins on hardware and connectivity: longest cable in class, dual Wi-Fi/4G reliability, weatherproofing, included solar diversion, and 25% off for British Gas customers — the practical, robust pick, especially inside the British Gas ecosystem. Ohme Home Pro is the smart-charging champion: it reads Agile’s half-hourly prices and extracts maximum value from dynamic tariffs — the choice for tariff optimisers, if less remarkable as hardware. Octopus Charge offers the most hands-off automatic scheduling within the Octopus world — ideal for set-and-forget simplicity on an Octopus tariff. The rule: best hardware and British Gas savings → Hive; squeezing a dynamic tariff → Ohme; effortless Octopus automation → Octopus Charge. (Our Egg charger review covers another popular rival, and the compatible-chargers guide maps the field for tariff smart-charging.) All charge at 7.4kW identically well — you’re choosing connectivity, smarts and ecosystem.
Our score: 4.1 / 5
Hive Sync Energy 2 — great hardware, good-not-great smarts
The bottom line: The Hive Sync Energy 2 is a dependable, well-built charger with the best cable and connectivity in its class, now with solar diversion and Intelligent Octopus Go support. It gives a little ground on warranty length and smart-app polish, so tariff obsessives and Agile users may prefer an Ohme — but for most drivers, especially British Gas customers banking the 25% Power+ saving, it’s a robust, sensible, quietly excellent choice.

Frequently asked questions
Is the Hive EV charger any good?
Yes — a solid, reliable charger. The current Sync Energy 2 has the longest cable in class (7.5m), dual Wi-Fi/4G connectivity, weatherproof build and solar diversion. It trails the best only on warranty length (3 years) and smart-app polish. We score it 4.1/5.
How much does it cost?
~£400–£549 unit only, from ~£1,019 fully installed via British Gas (install ~£460–£900 by property). No need to be a BG energy customer; BG electricity customers get 25% off charging via Power+. Renters/flats can claim £350 OZEV grant.
Does it work with Octopus / Intelligent Octopus Go?
Yes — on Octopus’s approved IOG list since late 2025 (older reviews saying otherwise are stale). Its own app handles Octopus Go and fixed-window tariffs too. It doesn’t read Agile’s half-hourly prices, so Agile users still want an Ohme.
Why does it keep going offline?
That’s the older rebadged Alfen units (GPRS via a Matt:e device). The current Sync Energy 2 fixed it with dual Wi-Fi + 4G. For an old unit, power-cycle it and its earthing device — see our troubleshooting guide; for a new one, it’s essentially been designed out.
Does it work with solar panels?
Yes — built-in solar diversion (SolarCharge) via a CT clamp sends surplus generation to the car instead of exporting it. Confirm the clamp is in your install quote. Pair daytime solar with cheap overnight charging for the cheapest running cost.
Hive, Ohme or Octopus Charge?
Best hardware, longest cable and British Gas savings → Hive. Squeezing a dynamic Agile tariff → Ohme Home Pro. Effortless hands-off Octopus automation → Octopus Charge. All charge at 7.4kW equally well; you’re choosing smarts and ecosystem.
The verdict
The Hive Sync Energy 2 is a quietly impressive piece of kit that’s easy to underrate because it isn’t flashy. What it does, it does properly: the longest cable you’ll find, connectivity that refuses to drop, weatherproofing that shrugs off a British winter, and solar diversion built in rather than upsold — and it answered its predecessor’s worst flaw so completely that the old “offline” complaints now read as a different product’s problem. For British Gas customers, the 25% Power+ saving turns a good charger into a genuinely economical one.
It isn’t the smartest charger money can buy — Agile obsessives and app-tinkerers will still prefer an Ohme, and the 3-year warranty is a fair mark against it. But for the ordinary driver who wants a robust, reliable, solar-ready charger that just works, it’s an easy recommendation. And it’s at its best as part of a bigger picture: solar panels feeding the car by day, cheap grid power by night. A couple of free, no-obligation quotes from MCS-certified installers will price that whole setup — panels, charger and all — so the car ends up running on sunshine and off-peak pennies rather than forecourt prices.
