Tethered vs Untethered EV Charger: Which Should You Choose?

If you are buying a home EV charger in the UK, one of the first decisions you will face is whether to choose a tethered or untethered unit. Tethered chargers come with a permanently attached cable, so you simply grab it and plug in. Untethered chargers have a socket only, meaning you supply your own cable each time you charge.

Many popular home chargers are sold tethered for convenience, but untethered models suit specific situations better. This guide compares both types on price, practicality, and long-term value so you can make the right choice for your household.

Tethered vs Untethered: What Is the Difference?

A tethered EV charger has a charging cable permanently attached to the unit. You walk up, grab the cable, and plug it into your vehicle. An untethered charger is a socket-only wallbox where you connect your own separate Type 2 cable each time you charge.

The charging speed is identical for both types. On a standard UK single-phase supply, both deliver 7.4kW and add roughly 20–30 miles of range per hour. The difference is purely about convenience, aesthetics, and flexibility.

Tethered models come with a fixed cable, usually 5 to 6.5 metres of Type 2 cable with a holster to store it on the wall. Untethered models sit flush against the wall and look neater, but you need to fetch your cable from the boot or garage, connect both ends, and store it after every charge.

Tethered vs Untethered EV Charger Comparison

The table below compares tethered and untethered chargers across every factor that matters for a home installation. Prices were checked in October 2026 and include VAT.

Tethered EV Charger: Pros and Cons

Tethered chargers are the default on many popular UK home chargers because they remove friction from daily charging. The cable is always ready, always in the same place, and requires no effort to set up. For single-vehicle households with a dedicated parking space, a tethered unit is almost always the better option.

The downside is the cable itself. A 5–6.5m Type 2 cable hangs on the wall via a holster, which some homeowners find unsightly. Over time, outdoor exposure to rain, frost, and UV can degrade the cable sheath. If the cable fails, expect a repair or replacement bill, and on some units the cable cannot be user-replaced.

Untethered EV Charger: Pros and Cons

Untethered chargers appeal to households that value flexibility and a clean wall-mounted look. Because you supply your own cable, you can choose any length from 3 to 10 metres and store it in the garage or boot between charges.

The trade-off is the daily routine. Every charge requires you to open the boot (or retrieve the cable from storage), connect both ends, and reverse the process when done. In the rain or on cold mornings, this gets old quickly. You also need somewhere dry to store the cable to prevent degradation.

Beyond the three chargers priced below, the Tesla Wall Connector, Hypervolt Home 3 Pro and Andersen A3 are all sold as tethered home chargers, while the Easee One is a socketed unit with an app-controlled cable lock.

Price Comparison: Tethered vs Untethered

Untethered chargers are typically around £50 cheaper because the manufacturer does not include a cable. However, you will need to buy a separate Type 2 cable (£100–£250 depending on length and brand), which can close or eliminate the price gap.

The Ohme Home Pro is tethered only, but Ohme sells a separate untethered model, the ePod, from £949 installed. The Zappi and Pod Point also come in both versions. Remember to factor in the cost of a separate Type 2 charging cable, plus your installation costs, when comparing total cost of ownership.

Which Should You Choose? A Decision Framework

The choice comes down to how many cars you charge, where you park, and whether a cable on the wall bothers you.

Single-EV households: A tethered charger suits most. The cable is always ready, and the roughly £50 extra (Pod Point Solo 3S: £1,049 tethered against £999 untethered) is small against years of daily charging.

Multi-EV households: If your cars need different cable lengths, or you want one cable that lives in the car for public charging too, an untethered charger lets you use whichever cable suits. Current EVs sold in the UK use a Type 2 connector for AC charging; Type 1 is mostly found on older imports.

Shared or rented parking: Untethered chargers work better where the cable might be a trip hazard or where other people park nearby. You can remove the cable entirely when you are not charging, leaving a clean wall socket.

For most UK households with a driveway and a single EV, a tethered home charger is the better buy. Untethered wins when one of the situations above applies.

How to Get an EV Charger Installed

Whether you choose tethered or untethered, the installation process is identical. A certified OZEV-approved installer will survey your property, confirm your consumer unit can handle the load, and fit the wallbox in 2–4 hours. Standard installation costs £300–£600 on top of a unit-only price such as the Zappi’s; Pod Point and Ohme include it in their headline prices.

If you need a longer cable run, a consumer unit upgrade, or an earth rod, expect to pay extra, quoted by your installer after the survey. Our full EV charger installation guide covers the process step by step, including what to check before booking an installer.
