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.
Around 70% of UK buyers choose tethered chargers 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.
- Around 70% of UK buyers choose tethered - the attached cable means you grab and plug in with no setup, making daily charging effortless
- Untethered chargers cost £50-£70 less - the Zappi untethered starts at £738 versus £780 for the tethered version
- Tethered cables are typically 5-6.5m Type 2 - long enough for most driveways, but cable replacement costs £100-£200 if damaged
- Untethered suits multi-EV households - different vehicles can use different cable lengths, and the wall unit looks cleaner without a dangling cable
- Both types deliver identical charging speeds - 7.4kW on a standard UK single-phase supply, adding roughly 30 miles of range per hour
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 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 are verified as of March 2026 and include VAT.
| Factor | Tethered | Untethered |
|---|---|---|
| How it works | Cable permanently attached to the unit | Socket only; you bring your own cable |
| Convenience | Grab and plug in, no setup | Must fetch, connect, and store cable each time |
| Appearance | Cable and holster visible on wall | Compact, flush wall-mount |
| Typical price | £780–£1,049 | £738–£999 |
| Cable length | Fixed 5–6.5m (Type 2) | Your choice (3–10m cables available) |
| Charging speed | 7.4kW (single-phase) | 7.4kW (single-phase) |
| Multi-vehicle use | Works with any Type 2 EV | Swap cables for different connector types |
| Cable replacement | £100–£200 if cable fails | Replace your own cable independently |
| Weather exposure | Cable exposed outdoors year-round | Cable stored indoors when not charging |
| Best for | Single-EV households wanting ease | Multi-EV homes, shared parking, neat appearance |
Tethered EV Charger: Pros and Cons
Tethered chargers dominate the UK market 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, you are looking at £100–£200 for a replacement, 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.
Price Comparison: Tethered vs Untethered
Untethered chargers are typically £50–£70 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.
| Charger | Tethered Price | Untethered Price | Saving |
|---|---|---|---|
| Myenergi Zappi | £780–£865 | £738–£780 | £42–£85 |
| Pod Point Solo 3S | £1,049 | £999 | £50 |
| Ohme Home Pro | £999 (tethered only) | N/A | – |
The Ohme Home Pro is only available as a tethered unit. If you specifically want untethered, the Zappi and Pod Point are your strongest options. Remember to factor in the cost of a separate Type 2 charging cable when comparing total cost of ownership.
A good-quality 5m Type 2 cable costs £100–£150. Longer 10m cables run £180–£250. If you buy an untethered charger, factor this into your total budget alongside the installation cost.
Which Should You Choose? A Decision Framework
The right choice depends on your household setup, how many vehicles you charge, and how much you value daily convenience versus flexibility. Use the framework below to decide.
– Choose tethered if you have one EV, a dedicated parking space, and want the easiest possible charging routine – Choose untethered if you have multiple EVs with different connectors, shared parking, or strongly prefer a clean wall – Choose tethered if you charge daily and want to eliminate any extra steps – Choose untethered if you rarely charge at home and do not want a cable hanging on your wall
Single-EV households: A tethered charger is almost always the better choice. You charge frequently, the cable is always ready, and the £50 premium over untethered is insignificant compared to the convenience over years of ownership.
Multi-EV households: If your household has two or more electric vehicles with different connector types, an untethered charger with swappable cables provides more flexibility. You can keep a Type 2 and a Type 1 cable and use whichever your vehicle requires.
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 delivers the best balance of price and daily convenience. The 70% market share reflects this. Untethered is the smarter pick only when your situation specifically demands the extra flexibility.
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 the charger price.
If you need a longer cable run, a consumer unit upgrade, or an earth rod, expect to pay £150–£450 extra. Our full EV charger installation guide covers the process step by step, including what to check before booking an installer.
