What stands out
Main limitation
The installed range is an estimate. The source date above is separate from the editorial review date.
Humax's two official documents disagree about which MX7 is the weatherproof one. The datasheet, dated 11 August 2025, gives "Ingress Protection — Tethered: IP65, Socket: IP54". The spec table on Humax's own website, for the same charger, states the reverse: socket IP65, tethered IP54 at both cable lengths. The two are exactly inverted, and the product pages above them lead with a flat "IP65 Waterproof Rating" that names no variant at all.
IP54 is common enough at this end of the market that the rating on its own is not the complaint — the Easee One, the Indra Smart PRO and the Zaptec Go 2 all sit there. Not being able to tell which one is going on your wall is. Until Humax corrects the paperwork, the safe assumption for the socket unit is IP54: mount it under a porch, a canopy or inside a garage rather than on an exposed elevation, and get the ingress rating of the exact SKU you are buying — the socket unit is H95-0132 — confirmed in writing before the installer arrives.
Best for: a sheltered wall, and a buyer who wants OZEV approval, RFID and five years of cover at £599, and has no immediate need for tariff automation.
Installation
Fitting the Humax MX7.
The socket unit is 335 × 210 × 144 mm and 3.25 kg; the tethered units are 335 × 210 × 133 mm, at 4.72 kg (5 m) and 5.43 kg (7.5 m). 7.4kW on a 32A single-phase supply. The datasheet lists over-current, residual-current and surge protection inside the unit, along with an IK10 impact rating.
The CT clamp is in the box, with the wall bracket, two RFID cards and an extension connector, so load balancing needs no extra hardware bought in. It does need a cable run: Humax says the clamp "must be installed near the charger" and that a wireless CT is not supported, which is worth raising with an electrician before the quote rather than after. The socket version takes your own Type 2 cable — a non-issue for a Tesla, which ships with one.
Humax sells the installation itself. Its booking page advertises a standard fit from £450; the standard-installation package listed on Humax Direct is £500. Read either as a floor rather than a price. Standard covers up to 10 m of cabling, mounting, the safety components, testing, certification and the notifications; anything outside that is surveyed after you have bought and quoted separately, and Humax publishes no figure for it. Full walkthrough in our install guide.

Tariff compatibility
What it costs to run.
Humax answers this itself, and the answer is no. Its FAQ lists Octopus Intelligent support as "integration in progress, support coming soon", and Octopus Agile as "not officially supported yet". So the charger does not talk to a supplier today. Scheduling is manual windows set in the Humax app: adequate on a fixed off-peak tariff like Octopus Go, where the window is set once, and the wrong tool for Agile, where the price moves through the day and you want the charger doing the hunting. The Ohme Home Pro does that, and costs £60 less.
For a Tesla the gap is narrower than it looks. Intelligent Octopus Go reaches a Tesla through the car's own API rather than through the charger, so charger-side integration matters less here than it would to most other EVs. OCPP 1.6J is present if you would rather point the unit at third-party backend software. The wider pattern is in our smart-tariff chargers guide.

Compare every tariffPrice
What you actually pay.
The unit is currently £599. £450–£500 is the working installation range, putting a typical installed total at £1,049–£1,099. The final figure depends on the cable route, consumer unit and any groundwork.
Five-year total
£2,073
Charger, installation, and five years of electricity on EDF GoElectric, at 10,000 miles a year.
Less £500 if you qualify for the OZEV grant.
Against the field
How it compares.
At £599 the MX7 sits £60 above the Ohme Home Pro and £204 above the Indra Smart PRO. If the ingress question is what puts you off, the alternatives are the ones whose rating is not in dispute: the Ohme at £539 is IP65 and automates the tariff, the Indra Smart Lux is IP67 for £546, and the Sync Energy Wall Charger 2 is IP65 for £400.
What the Humax holds over the Ohme and the two Indras is five years of cover against their three — on the condition Humax attaches to it, that you register the unit online — plus the PLC module, RFID and IK10. The PLC module is also the basis of the V2G pitch on the box, and that pitch is the one to discount hardest: Humax states that the ISO 15118 software and certification are still in progress, that bidirectional use depends on the carmaker enabling it, and that it needs DNO sign-off besides. Buy the MX7 for what it does now. Our V2G explainer covers how long that wait has already been.
What we loved
- PlusOn the government's eligible chargepoint list as HUMAX MX7 (HS71007 / HS71007U)
- PlusFive years of cover if you register online — two more than Ohme or Indra give as standard
- PlusCT clamp supplied in the box, so load balancing needs no extra hardware
- PlusOver-current, residual-current (RCD) and surge protection built in
- PlusSold three ways: Type 2 socket, or tethered at 5 m or 7.5 m
- PlusOCPP 1.6J, with Wi-Fi, Bluetooth LE and Ethernet as standard and 4G optional
- PlusIK10 impact rating — the top of the scale
What we didn't
- MinusHumax's datasheet and its own website spec table give opposite IP ratings; the marketing above both says IP65 without naming a variant
- MinusThe five-year warranty is conditional: Humax's page reads "5 years warranty when you register this product online"
- MinusNo live tariff integration — Humax calls Octopus Intelligent support "in progress" and Agile "not officially supported yet"
- MinusHumax markets the hardware as V2G/V2H-ready, but says ISO 15118 software and certification are still in progress
- Minus£599 buys less tariff automation than a £539 Ohme Home Pro
- MinusLoad balancing needs the CT clamp wired back near the charger — a cable run to budget for, and Humax does not support a wireless CT
- MinusHumax Direct pre-ticks a standard-installation box, and publishes no figure for work outside its standard fit
