Best Lockable EV Sockets for Secure Charging: 2025 Expert Review
OR Electrics
18th Edition Qualified Electrician
Charging an electric vehicle at home is convenient, but for those without a driveway or garage, or those using a 'granny charger' (3-pin plug) on an external wall, security is a massive concern. I frequently visit properties where outdoor sockets have been tampered with or where water ingress has tripped the RCD because the cover wasn't up to scratch.
Unauthorised use of your electricity ('electricity theft') is becoming a genuine worry for homeowners in built-up areas. Furthermore, standard domestic sockets aren't always designed to be locked shut whilst a bulky EV plug is inserted. You need a solution that is weatherproof, robust, and lockable to stop opportunists.
In this review, I've analysed three lockable enclosures suitable for securing your EV charging point. I'll cover a budget options for basic weather protection, a stainless steel upgrade for durability, and a heavy-duty iron solution for high-risk areas.

Specs vs. The Real World
The Spec: "Waterproof Ratings (IP66 etc.)"
"The manufacturer claims the box is totally waterproof even in heavy rain."
Waterproofing is only as good as the seal around the cable. If the EV cable is thick and forces the lid slightly ajar, the seal is compromised. Always ensure the cable entry point is glanded or sealed properly.
The Spec: "Anti-Theft Protection"
"A lockable box stops anyone from using your electricity."
Plastic boxes are merely a deterrent; a determined thief can smash them in seconds. If you live in a high-risk area, you need a metal enclosure, or better yet, an internal isolator switch to kill power to the socket from inside the house.
My Top 3 Recommendations
Three options to cover different needs and budgets
Outdoor Socket Waterproof Box, 86 Type Electric Vehicle Charging Socket Lock Box
Lecreatekit
This is a standard 86-type plastic enclosure designed to fit over existing socket setups. It offers basic weather protection and a locking facility at a very low price. It's suitable for secure rear gardens where vandalism is unlikely, but you want to stop casual tampering or weather damage.
The Good
- Very affordable option for basic protection
- Transparent cover allows you to see if the charger is active
- Wide opening angle makes plugging in easier
The Bad
- Plastic construction is less secure against vandalism
- May become brittle over time in harsh UK frosts
Installer Tip:
This box is 'retro-fit' style. When installing, make sure you use silicone sealant along the top and side edges where it meets the brickwork to prevent water running down the wall and behind the unit. Leave the bottom open for drainage.

BESTYASH
Moving up significantly in quality, this BESTYASH unit uses stainless steel. This is the material I prefer for client installations in Leeds because it doesn't rust easily and withstands accidental knocks far better than plastic. It adds a professional finish to the exterior of a home.
The Good
- Stainless steel offers excellent weather resistance
- Much harder to break open than plastic alternatives
- Aesthetically pleasing for modern homes
The Bad
- Metal enclosures must be properly earthed for safety
- Higher price point
Installer Tip:
Safety Warning: As this is a metal enclosure, it is absolutely critical that it is earthed properly. If a live wire comes loose inside and touches the metal box, the box becomes live. Ensure your electrician bonds the box to the earth terminal.

INOOMP
If your charging point is accessible from a public street or a shared driveway, you need something robust. This INOOMP box features iron construction, making it significantly heavier and tougher than standard covers. It is designed specifically to prevent unauthorised access in semi-public areas.
The Good
- Heavy-duty iron construction is very secure
- Ideal for front driveways or shared parking areas
- Designed to withstand impact
The Bad
- Iron can be prone to rust if the paint is chipped (unlike stainless steel)
- Industrial look might not suit all domestic tastes
Installer Tip:
Due to the iron construction, check the paintwork annually. If you spot any chips from plugging in your EV cable, touch them up with metal paint immediately to prevent rust setting in, especially in our damp UK climate.
