When buying a home EV charger, one of the first decisions you'll face is whether to get a tethered (cable attached) or untethered (socket only) unit. Here's everything you need to know to make the right choice.
What's the Difference?
Tethered Chargers
A tethered charger has a permanent cable attached to the unit. The cable is typically 5–7.5 metres long and ends in a Type 2 connector (the UK/EU standard).
How it works: Walk up, grab the cable, plug into your car, done.
Untethered Chargers
An untethered charger has a socket only — no permanent cable. You use your own Type 2 charging cable, which you plug into both the charger and your car.
How it works: Get your cable from the boot, plug one end into the charger, the other into your car, then stow it away afterwards.
Quick Comparison
| Factor | Tethered | Untethered |
|---|---|---|
| Convenience | More convenient | Less convenient |
| Cable storage | Always there, may hang | No cable on wall |
| Appearance | Cable visible | Neater look |
| Flexibility | Fixed cable length | Any cable length |
| Future-proofing | Tied to connector type | Swap cables easily |
| Security | Cable can't be stolen | Cable stored in car |
| Cost | Similar | Similar (but need cable) |
The Case for Tethered
Maximum Convenience
This is the biggest advantage. With a tethered charger:
For daily charging, this convenience adds up. It's especially valuable in bad weather or when you're tired.
Always Ready
The cable is always there. You can't forget it, lose it, or leave it somewhere. No "where's the charging cable?" moments.
Security
A permanently attached cable can't be stolen from your car boot. While cable theft is rare, it does happen with expensive Type 2 cables (£100–200 to replace).
Tidier for Some
Some people prefer the cable neatly coiled on a holder next to the charger rather than loose in their boot.
The Case for Untethered
Cleaner Appearance
Without a cable hanging on the wall, untethered chargers look neater. If aesthetics matter to you — or you're installing on a visible front wall — this can be significant.
Flexibility
With your own cable, you can:
Future-Proofing
If you change to an EV with a different connector (unlikely now, but possible), you just buy a new cable. With a tethered charger, you'd need to replace the whole unit.
Multi-Car Flexibility
If you have two EVs with different connector types (e.g., one Type 2, one Type 1), an untethered charger with two cables offers flexibility.

Popular Models by Type
Tethered Options
| Charger | Cable Length | Price |
|---|---|---|
| Ohme Home Pro | 5m or 7.5m | £650–750 |
| Pod Point Solo | 5m | £500–650 |
| Wallbox Pulsar Plus | 5m or 7m | £550–700 |
| MyEnergi Zappi | 6.5m | £800–950 |
Untethered Options
| Charger | Socket Type | Price |
|---|---|---|
| Ohme Home Pro | Type 2 | £650–750 |
| Pod Point Solo | Type 2 | £500–650 |
| Wallbox Pulsar Plus | Type 2 | £550–700 |
| MyEnergi Zappi | Type 2 | £800–950 |
Note: Most popular chargers are available in both versions at similar prices. The untethered version doesn't include a cable, so factor in £80–150 for a quality Type 2 cable.
Cable Considerations for Untethered
If you choose untethered, you'll need a Type 2 to Type 2 cable.
Cable Lengths
| Length | Use Case |
|---|---|
| 5m | Standard — suits most driveways |
| 7.5m | Longer reach — useful if parking varies |
| 10m | Maximum flexibility — for longer distances |
Tip: Measure the distance from your charger location to your car's charging port in the furthest parking position. Add a metre for slack.
Cable Quality
| Price Range | Quality Level |
|---|---|
| £50–80 | Budget — functional but may not last |
| £80–120 | Mid-range — good balance of quality and price |
| £120–200 | Premium — robust, weather-resistant, long warranty |
Recommended: Spend at least £80 on a quality cable. It's handling high currents regularly — don't cheap out.
Where to Buy
Installation Considerations
Cable Management (Tethered)
Tethered chargers usually come with a cable holder or hook. Consider:
Socket Protection (Untethered)
Untethered chargers have an exposed socket when not in use:
What About Connector Types?
Type 2 (Standard)
Virtually all EVs sold in the UK since 2018 use Type 2 connectors. If you're buying a new or recent EV, it will be Type 2.
Tethered: Get a Type 2 tethered cable — it will work with any modern EV.
Type 1 (Legacy)
Some older EVs (mainly Japanese imports pre-2018) use Type 1 connectors. These include older Nissan Leafs, Mitsubishi Outlanders, and some Kia/Hyundai models.
If you have a Type 1 car:
Future Connectors
Type 2 is the established European standard. There's no indication this will change. Future-proofing concerns are largely theoretical — your charger will almost certainly work with any EV you buy in the next 10+ years.
Cost Comparison
Tethered Total Cost
Untethered Total Cost
Verdict: Roughly the same overall cost. Untethered is slightly more when you factor in the cable purchase.
Our Recommendation
For Most People: Tethered
The convenience factor wins for daily home charging. Grab the cable, plug in, done. No messing with boot cables in the rain.

Summary
| Priority | Recommendation |
|---|---|
| Maximum convenience | Tethered |
| Cleanest appearance | Untethered |
| Multiple vehicles | Untethered |
| Future flexibility | Untethered |
| Daily ease of use | Tethered |
| Security | Tethered |
| Overall best choice | Tethered (for most) |
Both options work well — there's no wrong answer. If you're unsure, go tethered. The daily convenience of not handling cables almost always outweighs the theoretical flexibility of untethered.
