From the first building NOC to the final inspection, DEWA decides when your project can be powered and supplied.
Heron Contracting Dubai coordinates load calculations, design drawings and inspections with DEWA-accredited professionals, so your supply, fit-out connection or solar system is approved in the right order.
DEWA controls electricity and water supply in Dubai. Its approvals sit at several points in a project, from the first NOC to the energisation of the final meter.
DEWA approval confirms your load, design and installation can connect safely to the electricity and water networks.
The Dubai Electricity and Water Authority (DEWA) generates, transmits and distributes electricity and water in Dubai. For construction and fit-out projects it issues building NOCs, approves electrical and water designs, inspects installations and connects supply.
People searching “DEWA NOC”, “DEWA approval” or “DEWA connection for fit-out” are usually trying to work out which stage applies: the early building NOC, the design approval, the inspection or a later change to load.
Depending on your project, DEWA approval can include
DEWA approval isn’t one form. It’s a sequence of NOC, design, inspection and connection stages.
For projects under Dubai Municipality, DEWA’s building NOC is typically requested through the Dubai building-permit system. Other zones use their own routes.
Electrical and water designs come after the NOC and before the inspection. Skipping a step breaks the sequence.
DEWA’s work connects to other approvals on the same project:
What late DEWA planning costs you
Settle the load and switch-room location before layouts are fixed. Moving a substation or LV room after review resets drawings across disciplines.
The service you need depends on the stage and the type of work. These are the categories that come up most often.
Early technical clearance of grid capacity and supply arrangements at the plot.
Some projects only need a plot utilisation NOC without an electrical load.
Clearance for water supply arrangements to the building or plot.
Review of low-voltage drawings, load schedules and switch-room details.
Larger developments may need an HV substation, reviewed for location, size and civil works.
Substation requirements should be settled before the ground floor plan.
After design approval and installation, inspection and payment lead to connection.
Tenant fit-outs need a connection process, linked to landlord consent and tenancy registration.
Application and approval for new water connections and modifications to the water network.
Before demolition, supply must be isolated and records updated.
Grid-connected solar goes through a staged process using accredited professionals.
Ground-mounted systems aren’t allowed under the programme.
DEWA runs builder services online. For projects under Dubai Municipality, building NOC requests are made through the building-permit system rather than a separate DEWA portal.
Applied isn’t approved. A design can be returned for technical comments even when every field was filled.
DEWA reviews drawings and loads, not just uploads. Quality has to be in the design.
DEWA’s digital services are used by enrolled consultants and contractors. Typically they let you track:
DEWA approvals follow a fixed sequence. Doing each stage in order is what keeps supply on schedule.
Check who issues the building permit and whether the NOC is requested through the permit system or DEWA directly.
Prepare connected and maximum load estimates for electricity and water demand.
Submit through the right channel with plot details and load. Receive the NOC and estimate.
Use consultants and contractors enrolled with DEWA and engineers authorised for electrical work.
Fix LV, switch and meter room positions and any HV substation requirement.
Single-line diagrams, load schedules, room layouts and distribution board details.
Submit the design package, answer comments and receive approval before installation.
Install to approved drawings, then carry out contractor inspection and testing with certificates.
Apply for inspection once the site is ready and complete any snags raised.
Pay outstanding amounts, receive clearance and have supply connected.
There’s no universal list. Pick a group to see what a typical DEWA application may need.

Don’t reuse an old checklist. Always check the current DEWA-specific requirements. A document list from a previous project shouldn’t be copied across to a new one.
Almost everyone who builds or changes a building touches DEWA. Here is what each role should know.
Install only after design approval, and keep testing certificates for inspection.
Own the load calculations, the NOC strategy and the DEWA design package.
Tenant fit-outs have their own connection process tied to landlord consent.
Know when rooms, risers and substations need to be ready for inspection.
Switch-room positions, risers and wet areas above electrical rooms are design constraints.
Keep load records, approvals and NOCs for the building.
Plan substations, load allocations and phasing with DEWA from the master plan.
Kitchens and chillers raise load. Check capacity before ordering equipment.
Treat load increases and changes to distribution as controlled work.
Use accredited firms, and follow the NOC, design, installation and inspection sequence.
For fit-out contractors and electrical teams
Power is where fit-out budgets quietly change. Answer these before pricing, so load, rooms and inspections are in the quotation.
If the load increases, the supply arrangement may need to change.
Electrical work is controlled work. Take extra care with:
A unit can look perfect and still not have the power. Equipment loads and available capacity decide whether the activity works.
The right order
Confirm the available load, meter arrangement and landlord rules support your equipment before committing.
The costly order
Ordering first is how a kitchen finds out the supply can’t take the ovens.
The fastest strategy usually isn’t rushing the submission. It’s removing uncertainty before you submit.
Building NOC isn’t in hand when design starts.
Connected load grows after approval.
Consultant or contractor not enrolled with DEWA.
Room size or location doesn’t meet rules.
HV requirement found late.
Not in DEWA’s prescribed format.
Inspection requested before testing certificates ready.
Repeated failed inspections.
Water NOC or meter arrangement missing.
Supply isolation not arranged.
One revision creates three new inconsistencies.
Most delays aren’t one dramatic mistake. They’re small coordination problems that stack up.
A clean first submission is usually worth more than submitting a few days earlier with unresolved issues.
Three questions to settle before you plan the programme.
There’s no single answer. Some design reviews are short, but the overall timeline includes NOC, design, installation, testing, inspection and snags. It depends on:
There’s no flat DEWA price. Connection cost depends on load and works, so scope first and price each part. Typical components:
Can you start work before DEWA Approval?
A submitted application is not permission to construct.
Pre-submission checklist
Tick each item as you confirm it. It’s a quick way to spot what’s still open before you spend time on a submission.
Always verify the latest requirements. Forms, portals and requirements change over time. For current applications, confirm them directly with Dubai Electricity and Water Authority and the other authorities involved.
DEWA approval shapes the building. Before you commit, answer these five questions.
Once these are answered, the DEWA route becomes far more predictable: fewer redesigns, fewer failed inspections and a supply that’s ready when the building is.
Straight answers on DEWA Approval, from who applies to what happens at completion.
DEWA approval covers the NOCs, design approvals and inspections needed to connect electricity and water to a building or fit-out.
It’s an early clearance for electricity or water supply arrangements. For permit projects it’s generally requested through the building-permit system.
DEWA-enrolled consultants and contractors submit applications, with owner authorisation as needed.
Yes. Fit-out connections typically need a landlord NOC in DEWA’s format, approved distribution details and inspection.
Yes. Designs are approved first, and installations follow the approved drawings.
Larger loads may need an HV substation, whose location and size should be approved early.
DEWA inspects the installation, issues results or a snag list, and requires snags closed before connection.
Water connections and network modifications have their own NOC and approval steps.
Demolishing permits for electricity and water help ensure supply is isolated before works.
Shams Dubai follows NOC, design approval, installation and inspection using accredited professionals.
No. A landlord NOC is private approval. DEWA approval is separate and technical.
Installing before design approval risks rework and failed inspection. Wait for approval.
