For EV charger installation in Dubai, DEWA treats a home charger like any other appliance behind your meter. Its guidance is that home chargers can be fitted by a third party, and that a DEWA-approved electrical contractor should do the work. Most villas need no DEWA application at all, unless the charger pushes the property past its approved load. Apartments add one step: the building’s approval.
This guide covers what DEWA requires, what a competent electrician checks before quoting, how villas and apartments differ, and what drives the cost. If you already own a charger and want it fitted, our EV charger installation page explains how we work.
What does DEWA require for a home EV charger?
DEWA’s consumer FAQ sets out the basics:
- Behind the meter. Home chargers can be installed by a third party at your premises, behind your meter, in the same way as other home appliances.
- Who installs. DEWA-approved electrical contractors should be used for installing any electrical equipment in Dubai, including home charging stations.
- Billing. Electricity used for home charging is added to your normal DEWA bill at standard residential rates.
DEWA’s EV Charging Technical Regulations (version 1.0, May 2025) cover private and public chargers. Both must comply with the IEC standards the document lists, including IEC 61851 for the charger and IEC 60364 for the installation. Chargers must operate at up to 55 °C ambient, and the regulations restrict charging from Mode 1 and Mode 2 cables on extension leads.
Two DEWA rules apply to buildings rather than households. Under Directive No. 1 of 2017, organisations and developers need DEWA approval before installing or operating any EV charging station, and anyone operating public charging equipment needs a DEWA charge point operator (CPO) licence. A charger for your own household is private equipment.
If the charger takes a villa past its approved load, the contractor applies to DEWA for a load increase.
Does the installer need to be DEWA-registered?
DEWA’s guidance is that home charging stations should be installed by DEWA-approved electrical contractors. DEWA publishes a searchable Consultant and Contractor Listing on its website, showing each enrolled company’s trade licence number and category. Ask any installer for their trade licence number and check it there before work starts.
Also ask for the load calculation, cable size, protective device and handover test results in writing.
What does the electrician check before quoting?
1. Load assessment
IEC 60364-7-722, the international wiring rule for EV charging, treats each charge point as running at its full rated current, with no allowance for diversity unless load management is fitted. That matters because a charger runs for hours:
| Charger | Current drawn |
|---|---|
| 7.4 kW single-phase | 32 A on one phase |
| 11 kW three-phase | 16 A per phase |
| 22 kW three-phase | 32 A per phase |
The electrician compares that draw with your approved load and the property’s real peak demand, which in August includes every AC unit running at once. If the numbers are tight, the options are a load-managed charger that throttles itself around household demand, a lower current setting, or a DEWA load increase.
2. Distribution board and spare way
The charger needs its own dedicated circuit from the DB. IEC 60364-7-722 requires it, and sharing with garage sockets or a water heater is the classic shortcut that trips every evening. No spare way, or an old board with no room for a modern protective device, means a DB board upgrade comes first.
3. Cable sizing
Cable size depends on the current, the length of the run (voltage drop), how the cable is installed, and the ambient temperature along the route. A cable clipped to a sun-exposed wall or buried in a hot trench carries less current than the same cable indoors. A long run from the DB to a gate-side parking bay is where undersized cable most often appears.
4. RCD type: Type A or Type B?
Each charge point needs its own RCD, 30 mA or less and at least Type A. EV chargers can also leak smooth DC fault current, which can blind an ordinary RCD, so IEC 60364-7-722 requires DC protection by one of three routes:
- a Type B RCD; or
- a Type A RCD plus a residual direct current detecting device (RDC-DD) to IEC 62955, which trips at 6 mA of smooth DC; or
- a Type F RCD plus an RDC-DD.
Many wall chargers have the 6 mA DC detection built in, in which case a Type A device upstream meets the rule. The charger’s installation manual states which applies. A Type AC RCD should never protect an EV charger. On our installations, the charger circuit lands on its own RCBO in the board, so a fault trips the charger, not the house.
5. Earthing
DEWA’s regulations list the low-voltage earthing system as TN. In a TN system, IEC 60364-7-722 says the circuit supplying a charge point must not include a combined protective and neutral (PEN) conductor. The electrician checks earth continuity and earth fault loop impedance at the charger position, which matters most on long outdoor runs.
6. Location, testing and handover
The position is checked for direct sun, wash-down water and vehicle impact; DEWA’s AC charger specification is IP54 and IK10. At handover: insulation resistance, earth loop impedance and an RCD trip test, then a charging test on your own car.
Villa or apartment: what changes?
Villas and townhouses are the simple case: your DB, your meter, your wall and your parking. The variables are distance and load. A villa still on original wiring may need a villa rewiring conversation at the same time.
Apartments add the building. The parking bay, the riser and the car park containment are common property, so building management or the owners association has to approve the installation, normally through a no-objection certificate (NOC). The building decides where the supply comes from, your apartment’s DB through the riser or a supply point it designates, and may set conditions on cable routes or charger model. No installer can promise the building’s answer. Shared chargers for residents are a building project under DEWA’s rules for organisations and operators.
What does a home EV charger installation cost in Dubai?
Every installation is quoted fixed and in writing after the load check, with each item on its own line. These are the factors that move the price:
| Cost driver | Why it matters |
|---|---|
| Cable length and route | Longer runs need thicker cable to limit voltage drop |
| Single-phase or three-phase | Three-phase needs more cores and a four-pole device |
| DB spare way | No spare way, or an old board, adds a DB upgrade |
| DEWA load increase | Adds DEWA’s fees and time; load management can sometimes avoid it. |
| Groundwork | Trenching to a gate-side bay adds labour and making good |
| Apartment car parks | Long runs through building containment, and any building conditions |
Running costs are simpler. Home charging goes on your DEWA bill at standard residential rates. For comparison, since 30 September 2024 DEWA’s public EV Green Charger network charges registered users AED 0.70 per kWh plus VAT for AC charging.
Tesla Wall Connector and other brands
We are install-only: we fit the Type 2 charger you own, on a dedicated RCBO-protected circuit. A Tesla Wall Connector is installed to Tesla’s published specification, and BYD, Mercedes, BMW, Hyundai and other brands’ wall units are load-checked and tested the same way.
Home EV charger questions
Do I need DEWA approval to install an EV charger at home?
DEWA treats a home charger as equipment behind your meter, like other appliances, and asks that a DEWA-approved electrical contractor installs it. You only need a DEWA application if the charger takes your property past its approved load, in which case the contractor applies for a load increase. Apartments also need the building’s approval, usually an NOC.
Does an EV charger need a Type A or Type B RCD?
At least Type A, 30 mA, on its own circuit. EV chargers can leak DC fault current, so IEC 60364-7-722 also requires DC protection: either a Type B RCD, or a Type A RCD plus a 6 mA DC detection device. Many wall chargers have that detection built in. The charger’s manual says which your model needs.
Can I charge my EV from a normal socket with an extension lead?
No. DEWA’s EV Charging Technical Regulations restrict charging from Mode 1 and Mode 2 cables with extension cords, because extensions can overheat and add fault risk. For daily charging, a wall charger on a dedicated, properly protected circuit is the safe option.
Can I install an EV charger in my apartment car park?
Sometimes. The bay and riser are common property, so building management or the owners association must approve it, normally by NOC, and may set conditions on the supply point and cable route. Once the approval is in writing, the electrical work is similar to a villa installation, with a longer cable run.
How long does a home EV charger installation take?
Most straightforward villa installations are finished within a day on site. Long cable routes, trenching to a gate-side bay, a DB upgrade or a DEWA load increase add time, and in apartments the building’s approval usually takes longer than the work. The written quote gives you the programme before you commit.
