When does your renovation need DEWA approval? This guide covers the full process for electrical load changes, water connections, AC modifications, and more.
DEWA (Dubai Electricity and Water Authority) approval is required whenever your renovation affects the electrical or water infrastructure of your property. Not every renovation needs it — here is when you do.
Adding new AC units, increasing the number of power circuits, installing high-power appliances (saunas, jacuzzis, commercial kitchens), or upgrading from single-phase to three-phase power. Any renovation that increases your total electrical demand beyond the existing DEWA allocation requires approval.
Adding bathrooms, outdoor showers, garden irrigation systems, swimming pool water supply, or any new plumbing that requires a separate water connection or increased water flow capacity. Relocating the water meter also requires DEWA approval.
Changing from split-unit to ducted AC systems, adding AC to previously uncooled spaces (garage conversions, extensions), upgrading compressor sizes, or rerouting refrigerant lines. Like-for-like AC replacement at the same capacity and location does not need approval.
Installing solar PV systems under DEWA's Shams Dubai programme requires a separate application through DEWA. Your installer must be a DEWA-approved solar contractor. Grid-tied systems require a bidirectional meter installation by DEWA.
EV charger installation requires DEWA approval for the additional electrical load. Level 2 chargers (7-22kW) typically need a dedicated circuit and may require a load increase application. DEWA has specific guidelines for residential EV charging infrastructure.
Comprehensive smart home installations that modify the electrical panel, add dedicated circuits for automation systems, or require coordination with Etisalat/du for network infrastructure. Basic smart switches and WiFi devices do not need DEWA approval.
The DEWA approval process is straightforward when you have the right documentation. Here are the steps.
Gather your existing DEWA account details, property title deed, community developer NOC, contractor trade licence, and MEP drawings. Your electrical consultant prepares load calculations showing existing and proposed electrical demand.
Submit your application through the DEWA website or customer happiness centre. The application must include all technical drawings, load calculations, and supporting documents. Applications can also be submitted through the DEWA smart app.
DEWA engineers review the application and may schedule a site inspection. They verify the existing infrastructure can support the proposed changes. If a transformer upgrade is needed, DEWA will advise on the process and additional costs.
Once approved, pay the applicable fees and security deposits. DEWA issues a No Objection Certificate (NOC) which is required for your Dubai Municipality building permit application and your community developer approval.
After your renovation is complete, DEWA conducts a final inspection to verify the work matches the approved drawings. Once passed, your DEWA account is updated with the new load allocation and any meter changes are finalised.

Understanding electrical load helps you plan your renovation budget. Here are typical load requirements for common renovation elements.
| Renovation Element | Typical Load (kW) | Notes |
|---|---|---|
| Split AC unit (18,000 BTU) | 2.5 - 3.5 | Per unit |
| Ducted AC system | 5 - 15 | Depends on capacity |
| Swimming pool pump + heater | 3 - 8 | Heated pools higher |
| EV charger (Level 2) | 7 - 22 | Dedicated circuit required |
| Sauna / steam room | 6 - 12 | Three-phase often needed |
| Kitchen (commercial grade) | 10 - 25 | Induction + ovens |
| Jacuzzi / hot tub | 3 - 7 | Pump + heater |
* A typical Dubai villa has an allocated load of 50-100 kW. If your renovation pushes beyond this, a load increase application is required.
Modern smart home installations often require coordination between DEWA (power) and Etisalat/du (network). Here is how they interact.
Electrical panel modifications, dedicated circuits for automation controllers, power supply for motorised blinds/curtains, electrical infrastructure for security systems, EV charging circuits, solar panel grid connection, and any changes to the electrical distribution board.
Fibre optic installation and routing, structured cabling for home network, intercom and CCTV network infrastructure, WiFi access point cabling, and any modifications to the telecom entry point. Coordinate with your telecom provider early — lead times can be 2-4 weeks.
We handle DEWA applications, load calculations, MEP drawings, and all coordination with your community developer. Our electrical consultants are DEWA-registered and know the process inside out.
DEWA approval for renovation in Dubai takes 2-4 weeks and costs AED 500-2,000 in fees, depending on project scope. The process involves submitting engineering drawings to DEWA for electrical and plumbing NOC, ensuring compliance with Dubai Municipality standards. First Unicorn Interiors handles full approvals with 800+ projects experience.
