The cable is the star. The accessories are what make it last. A quality Type 2 charging cable can outlive two or three cars, but only if it’s stored correctly, mounted to avoid strain on the connectors, kept out of the hands of opportunistic thieves, and plugged into a socket that was designed for repeated daily use. This guide covers everything that wraps around your EV charging cable: what you need, what you can skip, and what order to buy in.
The EV charging accessory taxonomy
Before spending a penny, it helps to see the whole ecosystem at once. EV cable accessories fall into four distinct categories, and most drivers only need two or three of them.
- Root node EV Cable Accessories → 4 branches: (1) Tidy & Store [Cable Holders £10-£50, Cable Bags £15-£40] (2) Secure [Cable Locks £15-£30, Connector Covers £5-£15] (3) Protect the Circuit [Type B RCD £30-£80, RCBO £25-£60] (4) Upgrade the Socket [Outdoor IP66 Socket £15-£40 supply-only, Commando-to-Type-2 Adapter £25-£60]; each branch uses a distinct icon
Category 1 (Tidy & Store): wall-mounted cable holders and carry bags. These are the first purchases for almost every EV driver.
Category 2 (Secure): dedicated cable locks and connector covers. Needed when your cable is exposed in a shared or public space.
Category 3 (Protect the Circuit): Type B RCDs and RCBOs. These are electrical safety devices, not bolt-on extras, but regulatory requirements for a correctly installed EV circuit under BS 7671:2018+A2:2022, Section 722.
Category 4 (Upgrade the Socket): outdoor weatherproof sockets and Commando adapters. These sit at the wall end of your charging setup and determine what cable you can use and how safely you can use it.
Understanding these four categories means you can prioritise correctly rather than buying the shiniest thing first.
Must-have vs nice-to-have: a practical split
Not every accessory is for every driver. Here is the framework we use when customers ask us where to start.
- | Accessory | Priority | Situation |
- | Wall-mount cable holder | Must-have | Any home wallbox with garage or driveway |
- | IP carry bag | Must-have | Any away-from-home charging |
- | IP66 outdoor socket | Must-have | Any outdoor cable run at home |
- | Type B RCD / RCBO | Must-have (regulatory) | Any EV charging circuit |
- | Cable lock | Situational | On-street / public / unattended charging |
- | Connector cover / dust cap | Nice-to-have | Heavy rain exposure |
- | CT clamp (load balancing) | Upgrade | Multi-car or solar household |
- | Smart scheduling via tariff | Upgrade | Time-of-use tariff users |
In our own order data (EV Cable Hub first-party data), the most common first accessory purchase alongside a cable is a wall holder, closely followed by a carry bag for drivers who also use the public network. Locks are more popular with city drivers than rural ones, which makes intuitive sense. Buy in priority order and you won’t overspend on a setup you don’t need.
Cable holders and wall mounts: tidy charging starts here
A cable left in a coil on a garage floor is a tripping hazard, a kinking risk, and a slow way to damage the sheath. A wall-mounted cable holder solves all three problems for under £50 and takes twenty minutes to install.
The key specification to check is whether the holder includes a Type 2 holster (a dedicated cradle that accepts the connector head) or is simply a hook. A hook will hold the cable, but it leaves the connector dangling and exposed. A proper holster cradles the connector face-down, which is the detail that matters most: water and grit drain away from the pins rather than pooling against them. Over months of outdoor use, that distinction shows up in connector condition.
Install height matters too. Most manufacturers suggest 1,000-1,200 mm from floor level. That is waist-height, making it easy to lift the cable on and off without awkward bending, and high enough to keep the connector clear of puddles.
Material choice: ABS plastic is perfectly adequate for a covered garage; PA66 nylon is stiffer and more UV-stable if the holder will live outdoors or in direct sunlight.
For a deeper look at mount types, sizing, and strain-relief options, see our guide to wall-mounted cable holders.
Cable bags and boot storage: keep your car tidy
If you charge on the public network, or keep a backup cable in the boot, a dedicated carry bag is the single most practical accessory you can own. EV cables pick up a surprising amount of road grime, rainwater, and tarmac dust every time they’re used at a public charge point. A bag keeps all of that inside the bag, not loose in your boot.
The key specifications are: - Material: 1,200D woven polyester or equivalent is the floor for durability. Avoid thin nylon that will snag at the zip. - Water resistance: Most quality bags use a PU-coated lining or similar barrier. Formal IP ratings are rarely quoted for carry bags, but water-resistant zip closures and sealed seams are what to look for. - Size by cable length: A 5 m cable fits a compact bag (roughly 400 mm diameter circular, or 350 × 300 mm rectangular). A 10 m cable needs a bag in the 500-600 mm range. Don’t buy a bag sized for a 5 m cable and try to stuff in a 10 m. The coil will fight you every time.
Coil method: always coil the cable in loose, same-direction loops rather than figure-of-eight folds. Figure-of-eight folds cause opposite-direction twists that accumulate in the sheath and eventually cause kinking near the connectors.

Cable locks: the theft-deterrence layer
EV cable theft is predominantly opportunistic. The thief isn’t usually targeting your cable specifically; they’re targeting anything copper-containing that’s left unattended and accessible. A dedicated cable lock raises the effort required above the level most opportunists are willing to invest, which is all a deterrent needs to do.
The relevant specification is cable outer diameter. Standard Type 2 charging cables range from approximately 18 mm to 22 mm in diameter depending on the current rating and cable construction. Most dedicated EV cable locks advertise compatibility with cables up to 22 mm (the EVify Type 2 Anti-Theft lock is a well-documented example), which covers the full range of Type 2 cables in circulation.
Two approaches:
-
Lock the cable to a fixed point (a bike anchor, a ring bolt in the wall, the wheel arch of the car) using a cable lock looped through the cable coil. This prevents someone picking up the cable and walking away.
-
Lock the connector into the car’s charge port using a Type 2 port lock. This is separate from a cable lock and prevents the cable being unplugged mid-session. Some wallboxes include this as a tethered feature; with an untethered cable it requires a separate device.
Insurance note: some home contents and EV-specific insurance policies require evidence of reasonable security measures to cover cable theft. A cable lock is inexpensive evidence.
On-street risk: if you’re charging on-street as your primary method (no driveway), the IET Code of Practice for EV Charging Equipment Installation, 5th edition (2023), notes that cable management and security in public situations is a consideration during installation planning, underlining that this is a recognised real-world risk, not a hypothetical one.
Full coverage of lock types, on-street risk, and insurance considerations is in our guide to EV charging cable locks and theft prevention.
Outdoor EV sockets: the hardware behind the cable
The cable is only as reliable as the socket it plugs into. A standard 13A domestic socket used outdoors without a proper enclosure is not compliant with UK regulations for EV charging, and it will fail faster than you’d like.
The correct specification for an outdoor EV charging socket is IP66: full dust-proof and protected against powerful water jets from any direction. IP66 sockets close fully when the flap is down; even when the plug is inserted, the socket aperture is sealed around the plug body.
In addition to the IP rating, the socket itself must meet BS 1363-2 EV, a specific variant of the UK 13A socket standard that includes a cyclical load test simulating years of daily EV charging. Sockets meeting this standard are physically marked “EV” on the rear. Ordinary BS 1363 sockets (even outdoor ones) do not pass this test and are not suitable as dedicated EV charging outlets.
The circuit feeding the socket must comply with BS 7671:2018+A2:2022, Section 722, including appropriate RCD protection (Type B or Type A + 6 mA DC-fault device) and, where applicable, earthing considerations.
Critical point: installation must be carried out by a qualified electrician. The IET Code of Practice for EV Charging Equipment Installation, 5th edition (2023), is unambiguous on this: EV charging circuits are not a DIY job, and an incorrectly installed outdoor socket creates both a safety risk and a potential insurance liability.
If your home already has a 32A red Commando socket (IEC 60309) installed for a workshop or motorhome hookup, a Type 2-to-Commando cable is a quick win, but the socket itself still needs to be in good condition and correctly protected.
Full detail on socket types, IEC 60309 Commando options, and what to ask your electrician is in our guide to outdoor EV charging sockets.
Load-balancing: the smart accessory tier
Once the fundamentals are in place, the next level of upgrade is load management. If you have solar panels, a second EV, or a home on a limited-capacity supply, charging at full 7.4 kW whenever the cable is plugged in can trip the mains fuse or trigger a demand charge on certain tariffs.
A CT clamp (current transformer) installed on the supply tails by your electrician monitors your household’s total power draw in real time. A compatible wallbox or EVSE reads this signal and adjusts the charging current up or down to keep total demand below a set threshold. The result: you never trip the fuse, and on a time-of-use tariff you can set soft limits that prevent charging ramping up during peak-rate periods.
This isn’t a cable accessory per se (it’s a circuit-level upgrade), but it belongs in the accessories conversation because it’s the tool that makes a simple cable-and-wallbox setup behave intelligently.
We cover CT clamps in full in our guide to load-balancing EV charging at home. For now, the key point is: sort your cable, holder, and socket first. Add intelligence second.
Weatherproofing your charging system end-to-end
The accessories above don’t just protect individual components. Together they form a layered weatherproofing system. Each layer has a job, and a gap in any one of them weakens the whole.
- Layer 1 (bottom, foundation): IP66 Outdoor Socket, BS 1363-2 EV rated, fixed installation by qualified electrician; Layer 2: IP55+ EV Charging Cable, IEC 62196-2 Type 2 connector, TPU/TPE sheath rated for outdoor use; Layer 3: Weather-resistant Wall Holder, Type 2 holster, connector-down orientation for drip drainage; Layer 4 (top, circuit): Type B RCD / RCBO, 6 mA DC fault protection, BS 7671:2018+A2:2022 §722
Layer 1 (the socket): IP66, BS 1363-2 EV marked, installed by a qualified electrician. This is the foundation. Everything plugs into it.
Layer 2 (the cable): IP55 minimum, TPU or TPE sheath, Type 2 connector conforming to IEC 62196-2. Most quality cables from reputable UK suppliers meet this already; check the spec sheet before buying a budget import.
Layer 3 (the holder): weather-resistant mount, connector-down orientation. Keeps the most vulnerable part of the cable, the connector head, sheltered and correctly oriented when not in use.
Layer 4 (the circuit protection): Type B RCD or Type A + 6 mA DC-fault detector, as required by BS 7671:2018+A2:2022, Section 722. This is not weatherproofing in the traditional sense, but it is the safety net that turns a fault into a trip rather than a fire risk.
Every layer is interdependent. A perfect cable in a poorly drained holder, feeding through an undersized outdoor socket, protected by a Type A-only RCD, is not a safe system. Get all four right and your charging setup will outlast your car.
Frequently asked questions
Do I need any accessories with an EV charging cable?
You’ll always benefit from at least one: a wall-mounted holder if you have a permanent wallbox, or a carry bag if you charge away from home. The rest (locks, outdoor socket upgrades, load-balancing hardware) depend on your specific situation and charging pattern.
Which EV cable accessory should I buy first?
A cable holder if you have a fixed wallbox at home; a cable bag if you mostly charge at public or workplace points. These two cover the vast majority of practical value for most UK drivers. Everything else is a targeted upgrade from there.
Can I install my own outdoor EV socket?
No. Outdoor EV socket installation must be carried out by a qualified electrician. The socket must meet BS 1363-2 EV, and the circuit must comply with BS 7671:2018+A2:2022, Section 722, including the correct RCD type. DIY installation is unsafe and may invalidate home insurance.
What is the connector-down rule for cable holders?
Store the Type 2 connector head facing downward so that any moisture that enters drains away naturally rather than pooling against the pins. Purpose-built Type 2 holsters position the connector this way automatically; generic hooks often don’t.
Is a cable lock the same as a charger lock?
No. A cable lock secures the cable coil to a fixed point, preventing theft of the cable itself. A charger lock (or port lock) prevents the connector being unplugged from your car’s charge port mid-session. They solve different problems and are often used together for on-street charging.
What is the difference between IP55 and IP66 for EV accessories?
IP55 means protected against water jets from any direction, which is adequate for a cable or holder that lives outdoors in normal UK rain. IP66 means protected against powerful water jets from any direction, the minimum required for a fixed outdoor socket. Cables and portable accessories: IP55+. Fixed outdoor sockets: IP66.
Do I need a Type B RCD if my circuit already has an RCBO?
It depends on the RCBO type. Standard RCBOs detect AC faults only (Type A). EV charging circuits require detection of DC residual current at 6 mA, per BS 7671:2018+A2:2022, Section 722. You need either a Type B RCD, or a Type A RCD supplemented by a 6 mA DC-fault detector. A qualified electrician can confirm what you already have and what’s needed.
