EV Charging Cable Buyer's Guide: Everything to Check

Buying an EV charging cable comes down to five checks: the connector type your car needs, the current rating your home and car support, the length that reaches your inlet, the build quality, and the warranty. Get those right and you have the correct lead first time. For almost every UK car that means a Type 2 to Type 2 cable rated 32A for 7.4kW in a 5m to 10m length. The fastest route is our cable finder, which shows cables by car so the connector question is answered for you. This guide walks through each check in order.

At a glance: the five things to check

Which connector does your car need?

Check the inlet on your car first. 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 on the road. 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. The car end must match your car's inlet, while the charger end is always Type 2 at home and public AC points. Our cable finder settles this by car so you do not have to identify the socket yourself.

What current rating and power do you need?

Match the rating to the weakest link in your setup. A 32A single-phase cable gives 7.4kW, the ceiling for a standard UK home, adding roughly 25 to 30 miles of range per hour. A 32A three-phase cable gives 22kW, but only if you have a three-phase supply and a car that accepts three-phase AC, which is a minority. A cable delivers only what the weakest link allows, so a 22kW lead on a single-phase home still charges at 7.4kW. Most drivers should choose 32A single phase.

What length should you buy?

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 positions but weigh more, cost more and take more room to store. A coiled cable saves space but can be stiffer and heavier to handle in the cold.

How do you judge build quality?

Look for a jacket that stays flexible in cold UK weather, connectors that are firmly moulded and click home, and a power and current rating printed clearly on the lead. Type 2 connectors are designed to be safe to unplug and are weather-resistant when mated, so a well-made lead handles everyday outdoor use. Steer clear of unbranded cables with no stated rating. A cable is plugged in thousands of times over its life, so build quality directly affects how long it lasts.

Why does the warranty matter?

A warranty tells you the maker expects the lead to last and will stand behind it. Because a charging cable is handled daily, carries up to 32A and lives outdoors, a clear manufacturer warranty is real reassurance against early faults in the connectors or jacket. Weigh it alongside build quality rather than in isolation: a well-made cable with a solid warranty is a better long-term buy than a cheaper lead with neither, even if it costs a little more up front.

Frequently asked questions

What should I check before buying an EV cable?

Check five things in order: the connector your car needs, the current rating your home and car support, the length that reaches your inlet, the build quality and the warranty. For most UK cars that lands on a Type 2 to Type 2 lead rated 32A for 7.4kW in a 5m to 10m length. Our cable finder answers the connector question by car.

How do I know my car's connector?

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. Browsing by car on our cable finder removes the guesswork.

Do I need a 22kW cable?

Only if you have a three-phase home supply and a car that accepts three-phase AC. Otherwise a 32A single-phase cable for 7.4kW is right, since a cable delivers only what the weakest link allows. A 22kW lead on a single-phase home still charges at 7.4kW, so it is future-proofing rather than everyday extra speed.

What length cable is best?

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.

How can I tell a cable is good quality?

Look for a flexible jacket that copes with cold, firmly moulded connectors that click home, a clearly printed power and current rating, and a manufacturer warranty. Type 2 connectors are safe to unplug and weather-resistant when mated. Avoid unbranded leads with no stated rating, as build quality decides how well the cable survives daily outdoor use.

Does the warranty really matter?

Yes. A cable is handled daily, carries up to 32A and lives outdoors, so a clear manufacturer warranty is genuine reassurance against early faults. Weigh it with build quality rather than alone. A well-made lead with a solid warranty is usually a better long-term buy than a cheaper cable offering neither, even at a slightly higher price.
