A lot of charger for the money. Tethered from £302 with a 7.5-metre cable — longer than the Tesla Wall Connector and cheaper. Built-in solar diversion, PEN fault protection, IP65 + IK10 build. The caveats are Wi-Fi reliability (specify the 4G variant if in any doubt) and a less polished app than Ohme or Tesla. If you want a smart charger and want to spend as little as possible doing it, this is where to look. For API-level tariff automation, the Ohme Home Pro remains the upgrade.

Figures are estimates. Your actual saving depends on how much charging you do in the off-peak window versus during the day, and on your provider's standing charge. Read the individual tariff reviews for the full picture.

The cheapest smart tethered charger on the UK market, and the one with the longest cable. Tethered from £302 with a 7.5-metre lead — longer than the Tesla Wall Connector's 7.3 m. Built by Sync Energy, the EV charging brand of UK-listed Luceco PLC: less well-known in the EV space, but not a garage operation.

For the money, a surprisingly full feature set. TariffSense scheduling for the common two-rate tariffs. SolarCharge surplus diversion with a CT clamp. Dynamic load balancing, OCPP 1.6J. IP65 + IK10 ratings: fully weatherproof, impact-resistant. PEN fault protection built in, which usually removes the need for a separate earth rod at install. Interchangeable fascia plates in nine colours, if that matters. Wi-Fi reliability has been mixed in reviews — worth confirming strong signal at the mounting position before ordering, or specifying the 4G-equipped GG variant.

Best for: Budget buyers who want a long-cabled, fully-featured smart charger and don't mind a less-famous brand. Properties where 7.5 m of cable is the deciding factor.

Installation

2.5 kg without cable, 305 × 201 × 115 mm — compact and easy to mount. The 7.5-metre cable is the quiet winner here: longest fitted cable of any charger in this selection. IP65 keeps it fully weatherproof on exposed walls; IK10 handles knocks. Built-in PEN fault protection usually takes £50–£100 off install labour by removing the need for a separate earth rod (on most consumer units; depends on your installer's reading of the supply). No built-in RCD, so a Type A goes in at the consumer unit. Bluetooth for app setup; everyday connectivity is Wi-Fi or Ethernet, with 4G available on the GG variant for cellular-reliant sites. Full walkthrough in our install guide.

Tariff compatibility

TariffSense in the Sync Energy app schedules charging against your off-peak window. Works cleanly for Octopus Go and similar fixed-window tariffs — set the window, charging runs during it. No direct supplier API, so no automatic chase of Octopus Agile half-hours or extra Intelligent Go slots; the Ohme Home Pro still owns that ground. SolarCharge via the CT clamp diverts surplus solar — simpler than the Zappi's Eco+/Eco, but included in the price. OCPP 1.6J leaves the door open for third-party energy-management platforms. Full pattern in our EV tariff guide.

Price

Element	Cost
Unit (tethered, 7.5 m)	from £302
Unit (socketed)	from £362
Typical installation	£300–£600
Installed, total	£602–£962

Comfortably the cheapest smart tethered charger here. £176 below the Tesla Wall Connector (£478), with a longer cable and solar support included. The built-in PEN fault protection can take another £50–£100 off install labour. Eligible for the £500 OZEV grant for renters and flat owners, which makes this one of the cheapest genuinely-smart chargers you can buy.

Against the field

Against the Tesla Wall Connector: £176 cheaper, cable 0.2 m longer, and it adds solar and CT-clamp load balancing; loses on app polish and brand depth. Against the Ohme Home Pro: £233 cheaper but can't match the API-level tariff chase; on Intelligent Go or Agile, the Ohme's automation pays back its premium inside months. Against the GivEnergy: same budget-smart territory — the Sync Energy undercuts on price and wins on cable; the GivEnergy wins if you have a home battery. The main caveat is maturity: the app moved from Monta, and Wi-Fi reliability has been mixed in reviews. If that worries you, specify the 4G variant or look elsewhere.
