10m is the most popular EV cable length in the UK — the right answer for the largest share of UK driveways. It gives you 4-8m of physical reach with comfortable slack on either side, works for charge ports on either side of the car, and isn't so heavy you dread coiling it up.
When 10m is the right choice
- Wallbox 4-7m from where you park — typical garage-side or fence-mounted wallbox layout.
- Charge port on the opposite side of the car from the wallbox — adds ~2-3m of effective reach needed.
- You sometimes park nose-in, sometimes nose-out — the slack covers both directions without re-routing.
- You charge at public Type 2 posts and want enough length to reach awkward bay layouts — many public bays are designed for nose-in only with charge port on the right.
When 10m is NOT the right choice
- Wallbox right next to the parking spot — go with 5m. Less coil, less storage, slightly cheaper.
- Long driveway or shared drive across two properties — go with 15m, 20m or 25m. 10m won't reach.
- Charging across a road from a kerb-mounted wallbox — go with 15-20m.
Voltage drop and efficiency
At 10m, voltage drop on a 32A Type 2 cable is around 1-2% — meaning your 7.4kW wallbox delivers around 7.2-7.3kW to the car. Negligible in practical terms (saves about 1p/kWh on Octopus Intelligent). Don't over-think this; the difference between 5m and 10m on your bill over 12 months is under £20.
Connector type
Almost all 10m cables we stock are Type 2 — the UK and European standard since 2014. Type 1 10m cables exist for older Nissan Leaf and Mitsubishi Outlander PHEV, but the market is smaller. If you have a Type 1 car, see the dedicated Type 1 collection.
Power rating
10m cables are typically available in:
- 32A single-phase — 7.4kW max. The UK home wallbox standard. 7.4kW range.
- 32A three-phase — 22kW max. For three-phase homes with 22kW EVs. 22kW range.
- 16A single-phase — 3.6kW max. For older PHEVs and low-spec wallboxes. 3.6kW range.
Build construction
A 10m cable weighs around 4-5kg for single-phase and 6-8kg for three-phase. The cable itself is the bulk of the weight; the couplings add ~500g per end. What this means in practice: you want a cable that coils smoothly and stays coiled. Halogen-free woven jackets do this well; cheap rubber jackets don't, especially in cold weather. Look for:
- IP55 minimum on both couplings (the connector ends are the weather-sensitive parts)
- 1m drop-impact tested connectors (they get dropped on tarmac during winding)
- 5-year manufacturer warranty on premium cables; 3-year minimum on every cable we stock
Storage
A 10m cable lives in your boot when not in use. Pair with a cable bag — stops the connector tips picking up grit and protects your boot upholstery. Or, if you charge primarily at home, a wall holder next to the wallbox keeps the cable off the ground and the connectors out of the rain when not plugged in.
Pairing with a tethered wallbox
If you have a tethered wallbox at home (cable permanently attached), you don't need a separate 10m cable — you have one already. Buy a 10m cable when: you have a socketed wallbox, you charge at public Type 2 posts, you want a spare for a holiday let or visiting friends, or your tethered cable has been damaged and needs replacing.
What 10m won't do
It won't bridge to public DC rapid (CCS) — those are tethered to the rapid post. It won't make a 7kW wallbox charge faster — speed is limited by wallbox spec, not cable spec. And it won't help if your car's onboard charger caps at 3.6kW or 7kW — the cable rating is the upper limit, not the actual draw.
