As electric vehicles become increasingly popular across London, homeowners are seeking to install EV chargers at their properties for ease and convenience. But one common question we hear at RCD Electrical is:
"Can I safely install an EV charger in the rain?"
The short answer is yes, when done properly and professionally. In this article, we’ll walk you through how outdoor EV chargers are designed to handle wet conditions, the importance of correct installation, the role of waterproof ratings, and why trusting certified electricians like RCD Electrical is crucial for safety and performance.
EV Chargers Are Built for the British Weather
Modern EV chargers, especially those suited for domestic use, are engineered with weather resistance in mind. In fact, many are built to operate in rain, sleet, and even snow. The majority of outdoor chargers have IP65 or higher weatherproof ratings, meaning they are dust-tight and protected from low-pressure water jets from any direction.
So, if you’re standing under an umbrella watching the electrician work, rest assured — the charger itself is built for it. But here's the caveat: the product's durability is only as reliable as its installation.
Why Professional Installation Matters
Although EV chargers are designed for outdoor use, installing them safely in rain requires technical know-how and strict adherence to safety codes. At RCD Electrical, our certified installers follow BS 7671 Wiring Regulations and ensure every unit is:
-
Properly grounded (earthed)
-
Installed with waterproof seals
-
Tested for residual current device (RCD) protection
-
Mounted at correct height to avoid flood-risk areas
Any exposed wiring or improperly mounted unit could pose a hazard — particularly in wet conditions. That’s why it's essential that you do not attempt a DIY installation or hire non-qualified personnel.
Wet Weather Protocols at RCD Electrical
RCD Electrical’s team of fully qualified NICEIC-approved electricians is trained to follow strict wet-weather protocols during any EV charger installation.
When rain is forecasted or occurring, we take the following precautions:
-
Use of waterproof covers or tents during connection stages
-
Postpone high-voltage tasks if the surface is saturated
-
Ensure all tools and fittings are dry and grounded
-
Apply IP-rated cable glands to prevent water ingress
-
Conduct final insulation resistance testing before handover
These protocols allow us to maintain high standards — even in unpredictable London weather.
Understanding IP Ratings
Every outdoor EV charger must carry a robust Ingress Protection (IP) rating. Here's a quick guide:
| IP Rating |
What It Means |
Suitability |
| IP44 |
Splash resistant |
Covered locations only |
| IP65 |
Dust-tight, jet-proof |
Safe for open-air exposure |
| IP67 |
Waterproof for temporary immersion |
High-protection environments |
At RCD Electrical, we recommend a minimum of IP65 for all outdoor EV charging units. This ensures your unit remains safe and fully functional through rain, sleet, or snow.
What If It Starts Raining During Installation?
It’s a common concern — you book your appointment, the weather turns, and now you're unsure whether the installation should go ahead. If it’s light to moderate rain, our electricians will typically proceed using proper safety gear and weather protection.
However, in heavy rain or lightning conditions, RCD Electrical may choose to reschedule the installation to ensure absolute safety for you and our staff. You’ll never be charged extra for this – your safety comes first.
Can I Use My EV Charger in the Rain?
Absolutely. Once installed, your EV charger is perfectly safe to use in the rain, as long as:
-
The charging cable is intact
-
There are no exposed wires
-
You follow the user manual
-
The unit is properly maintained
Always plug and unplug the charger using dry hands and avoid standing in pooled water while doing so. At RCD Electrical, we show every customer how to operate their new charger safely in all weather conditions.
