How to Choose an EV Charging Cable in 5 Steps

Choosing an EV charging cable takes five steps: confirm the connector your car needs, match the power to your home and car, pick the right length, choose the correct current rating, then check the build quality. Follow them in order and you land on the right lead first time, which for most UK cars is a Type 2 to Type 2 cable rated 32A for 7.4kW in a 5m to 10m length. The simplest shortcut is to enter your registration on our home page, which shows only cables that fit your car. Here is each step in plain terms.

At a glance: the five steps

Step 1: Which connector does your car take?

Start with the inlet on your car. Type 2 (Mennekes, 7-pin) has been the UK standard on every EV and plug-in hybrid sold since 2018, so a Type 2 to Type 2 lead fits almost everything. Older, pre-2018 cars with a Type 1 inlet, such as an early Nissan Leaf or early Outlander PHEV, need a Type 2 to Type 1 lead instead. The car end must match your car's inlet, while the charger end is always Type 2. If you are unsure, entering your reg on the home page confirms the connector for you.

Step 2: What power does your setup support?

Match the power to the weakest link. Most UK homes are single phase, so 7.4kW (32A) is the ceiling a standard home delivers, adding roughly 25 to 30 miles of range per hour. Only a three-phase supply paired with a car that accepts three-phase AC reaches 22kW, and that combination is a minority. A cable delivers only what the weakest link allows, so aiming above your home's capability buys future-proofing, not everyday speed. For most drivers, plan around 7.4kW.

Step 3: What length do you need?

Measure the distance from where the charger sits to your car's inlet, then add a metre or two of slack. Five metres suits most driveways with a home wallbox. Choose 7m or 10m for on-street parking, shared chargers, or when the charging port is on the far side of the car. Longer leads reach more spots but weigh more, cost more and take more room to store. A coiled cable saves space but can be stiffer and heavier to handle.

Step 4: What current rating should you pick?

Choose the current rating that suits your power decision. A 32A single-phase cable delivers 7.4kW and is right for most UK homes. A 32A three-phase cable delivers 22kW, but only benefits you with a three-phase supply and a compatible car. Make sure the cable's stated rating matches your wallbox: pairing a 7.4kW box with a 32A single-phase lead is the standard combination, and it should be clearly printed on the cable itself so you can confirm at a glance.

Step 5: How do you check quality?

Finally, judge the build. Look for a jacket that stays flexible in cold UK weather, firmly moulded connectors that click home, a clearly printed rating, and a manufacturer warranty. Type 2 connectors are designed to be safe to unplug and are weather-resistant when mated, so a well-made lead copes with daily outdoor use. Avoid unbranded cables with no stated rating or cover. A cable is used thousands of times, so quality decides how long it serves you.

Frequently asked questions

How do I choose an EV charging cable?

Work through five steps: confirm your car's connector, match the power to your home and car, pick the length, choose the current rating, then check build quality. For most UK cars that gives a Type 2 to Type 2 lead rated 32A for 7.4kW in a 5m to 10m length. Entering your reg on our home page shortcuts the connector step.

Which connector does my car use?

Type 2 fits every EV and plug-in hybrid sold since 2018, so most cars need a Type 2 to Type 2 lead. Older pre-2018 cars with a Type 1 inlet, such as an early Nissan Leaf, need a Type 2 to Type 1 lead. The car end must match your car's inlet. Entering your reg confirms the connector without guesswork.

What power rating should I choose?

Plan around 7.4kW (32A single phase) for a standard UK home, which adds roughly 25 to 30 miles of range per hour. Only choose 22kW (32A three phase) if you have a three-phase supply and a car that accepts it. A cable delivers only what the weakest link allows, so aiming higher without support is future-proofing, not extra speed.

How long should the cable be?

Five metres suits most driveways. Choose 7m or 10m for on-street parking, shared chargers or a far-side charging port. Measure the real distance and add a metre or two of slack. Longer leads reach more spots but weigh more and take more room to store, and coiled cables can be stiffer to handle in cold weather.

What current rating matches a 7.4kW charger?

A 32A single-phase cable is the standard match for a 7.4kW wallbox. If you have a three-phase supply and a 22kW box, and a car that accepts three-phase AC, choose a 32A three-phase cable instead. The rating should be printed clearly on the lead so you can confirm it matches your charger at a glance.

How do I judge cable quality?

Look for a flexible jacket that copes with cold, firmly moulded connectors that click home, a clearly printed rating and a manufacturer warranty. Type 2 connectors are safe to unplug and weather-resistant when mated. Avoid unbranded leads with no stated rating, since build quality decides how well a cable survives thousands of uses outdoors.
