Installing an EV home charger in a Dubai villa — DEWA approval and wiring?
We've just gone electric and I'm trickle-charging off a normal 13A socket in the garage with the cable that came with the car. It works but it's painfully slow and the socket gets warm, which I don't love.
I want a proper wall box charger installed in the villa. Before I start calling people I'd like to understand the process here:
- Does a home charger have to be registered/approved with DEWA, or can any electrician just wire one in?
- Is there a specific DEWA EV scheme I should be going through?
- My villa is about 12 years old — will the existing distribution board handle a 7–11 kW charger, or is that a problem?
- Roughly what's involved on the day?
Don't need exact prices, just want to know what "done properly" looks like so I don't end up with a dodgy install on a high-load circuit.

Good call stopping the 13A trickle habit — a standard socket isn't built for hours of continuous near-full load, hence the warmth.
Here's how a proper Dubai home install works:
It goes through DEWA's EV Green Charger scheme, and it must be a DEWA-registered/approved electrical contractor — not just any handyman with a drill. DEWA (and Dubai Municipality standards) require the charging point to be installed and certified by an approved installer, so insist on that; it's the difference between a compliant, insurable install and a liability.
On the day, roughly: they assess your distribution board and available capacity, run a dedicated circuit for the charger protected by its own breaker and an RCD (a wallbox is a continuous, high-current load and needs its own protected line), mount the wallbox, and then register/energise it under DEWA. A typical home wallbox is 7–11 kW and gives most cars a full charge in about 4–6 hours overnight.
Your 12-year-old board is the real question. Adding an 11 kW load to an older villa board that's already near capacity may mean the installer specs a lower-power unit, or recommends a board upgrade first. A good DEWA-approved electrician will do that load check before quoting rather than after. Charge overnight and you'll also catch the cheaper off-peak pattern.
Details on the scheme are on DEWA's EV Green Charger page.
One add-on for anyone reading this in an apartment rather than a villa: it's more involved. You usually need the owners' association / building management NOC because the parking and the supply are shared, and there's the question of how the charging is metered back to you. Villas are far simpler because the supply and the parking are yours. If you're in a tower, start with building management before you get quotes.
Worth sizing the cable and breaker for the charger you might want next, not just today's car. The labour to pull a slightly heftier cable now is small; re-running it because you upgraded to a faster wallbox in two years is not. Ask the installer to future-proof the circuit while the wall's open.
