DEWA Approval Guide for Dubai Projects

A clear, practical walkthrough of the DEWA approval process for fit-outs, power upgrades, and new electrical connections in Dubai.

When You Need DEWA Approval

Most electrical works in Dubai that affect load, metering, or compliance require DEWA review and approval before work begins.

🏠 Tenant fit-out & office modifications
Power load enhancement & tariff upgrade
🔌 New electrical connections & meter works
Major panel, DB, or distribution modifications

Step-by-Step Approval Process

1

Initial Technical Survey

Site visit and full load assessment to understand existing electrical infrastructure and project requirements.

2

Design & Documentation

Preparation of single-line diagrams, load schedules, circuit design drawings, and all required DEWA application forms.

3

Submission

Application submitted through the DEWA Approved Contractor portal. Only registered contractors like Ampcore can submit directly.

4

Authority Review

DEWA technical team reviews the submission. Any comments or revision requests are addressed promptly to avoid delays.

5

Installation & Execution

Electrical installation works are carried out strictly as per the approved drawings and DEWA standards.

6

Inspection & Closeout

Final testing, DEWA inspection coordination, and energization or clearance certificate — project fully closed out.

Documents Usually Required

Trade license and tenant/owner authorisation letter
Premises details and existing load information
Electrical design drawings and load schedule
Technical datasheets where applicable
NOC and supporting approvals based on project type
DEWA approved engineer sign-off on documentation

Typical Timeline

A realistic planning window is 2 to 8 weeks depending on scope, authority feedback, and document quality. Early engineering preparation reduces delay risk significantly.

Project Type
Typical Duration
Key Variable
Meter / power upgrade (simple)
2 – 4 weeks
Document completeness
Tenant fit-out (small–medium)
3 – 5 weeks
Drawing approval cycle
Large commercial / industrial fit-out

Final inspection & energization

Common Mistakes That Delay Approvals

Incomplete load schedule — mismatched drawing notes or missing circuit data are the most common reason DEWA returns applications.
Late response to authority comments — DEWA sets response deadlines; missing them restarts the queue.
Scope changes after submission — modifications without formal revision require re-submission and added delay.
Non-compliant installation before inspection — work that deviates from approved drawings will fail inspection and require remedial works.
