DEWA approvals for electricity and water connections

For owners, developers and fit-out tenants who need DEWA's building NOC, load approval or a new connection. We prepare the load schedules and drawings, coordinate the enrolled consultant and contractor, and follow the file through to energisation.

A building can have every permit in place and still sit dark. In Dubai, power and water arrive only after the Dubai Electricity and Water Authority (DEWA) has accepted the load, checked the installation and released the supply, and that sequence starts long before the contractor finishes.

DEWA's involvement in a project comes in layers. There is an early no-objection certificate that lets the building permit go ahead. There is a load and design approval that fixes how much power the building may draw and how it is distributed. And there are inspections at the end before meters are fitted and the supply is switched on. Each layer depends on drawings and schedules that have to agree with each other.

We are a private consultancy, not part of DEWA. DEWA alone approves loads and connects supply. Many DEWA services can only be filed by consultants and contractors enrolled with DEWA, so we coordinate submissions through an enrolled consultant or contractor where that is required, and handle the technical preparation and follow-up around it.

When a project needs DEWA approval

Almost any project that creates a new supply point or changes the electrical or water demand of a property ends up with DEWA. The common triggers are:

New buildings

A new villa, residential block, warehouse or commercial building needs a DEWA building NOC for electricity and water as part of its building permit, then a permanent connection once the installation is complete.

Extensions and added load

Adding floors, a large extension, a pool plant room or heavy air-conditioning can push demand beyond what the existing connection was approved for. The revised load has to be designed and approved before it is connected.

Commercial fit-outs

A tenant fitting out a shop, office, clinic or restaurant inside an existing building needs its own distribution design approved and inspected before the unit's supply is released.

Demolition and site works

DEWA lists a separate electricity and water service for demolition permits, and works near its cables, substations or pipelines need its no-objection before excavation.

Rooftop solar also runs through DEWA, under the Shams Dubai initiative, but it has its own enrolment and connection route. We cover it on our solar panel approval page.

The main DEWA services behind a connection

DEWA's builder services are separate applications, though some are now bundled. Knowing which one applies avoids filing the wrong request.

DEWA service	What it does	Who files it
Building No Objection Certificate (electricity / water)	Confirms DEWA has no objection to the building permit from a supply point of view	Enrolled consultant or contractor
Getting Electricity Permits & Connections	Bundles the electricity building NOC with the connection request in a single application, followed by payment, inspections and energisation	Enrolled consultant or contractor
Getting Water Connections	The equivalent route for the building's water supply	Enrolled consultant or contractor
Getting Electricity Fit-out Connections	Design approval, LV inspection and supply for a unit fitted out inside a building that DEWA already serves	Enrolled contractor
Demolishing permits (electricity / water)	DEWA's clearance before a building is demolished	Enrolled consultant or contractor

For projects permitted by Dubai Municipality, DEWA says owners don't need to apply through DEWA's own channels for the building NOC. The request is submitted inside the municipality's building permit system and passed to DEWA digitally. Projects licensed by other authorities, such as free zones and special development areas, apply directly through DEWA. Read more about the municipality side on our Dubai Municipality approval page.

Documents and drawings DEWA asks for

DEWA's lists are short compared with a building permit, but every item is technical and must match the rest of the file. Depending on the service, expect to prepare:

Setting-out planFor electricity, DEWA asks for the meter location to be shown on larger loads. For water, the plan shows where the ground or underground tank sits.
Affection planRequired by DEWA only where the project is in a Dubai free zone area. See our affection plan service.
Total connected load and maximum demandThe project summary of connected load and the demand DEWA is being asked to supply.
MDB and SMDB schedulesSchedules for the main and sub-main distribution boards, consistent with the single-line diagram.
Final distribution board schedulesLoad distribution for the final boards, which is where most fit-out queries start.
Lighting and power layoutsWiring layouts showing circuits and points, submitted in the file types DEWA accepts (PDF and DWF for fit-outs).
Landlord NOCFor a fit-out, the building owner's no-objection in DEWA's prescribed format.
Supply termsDEWA's terms and conditions for supply of electricity and water, signed by the owner before the supply is released.
Site photographsPhotos of the installation at LV inspection stage.

These schedules come out of the electrical design. If you don't yet have an MEP consultant, our MEP design and approvals service prepares the load calculations and drawings DEWA reviews.

How the DEWA approval and connection process works

For a new building, the DEWA route runs alongside the building permit and finishes near completion. A typical path:

Establish the load

The MEP consultant calculates connected load and maximum demand from the architectural layout, the air-conditioning design and the building use. This number decides whether the plot needs a DEWA substation.

MEP consultant

Building NOC with the permit

The electricity and water building NOCs are requested, through the building permit system for Dubai Municipality projects or directly with DEWA elsewhere. DEWA lists both as free of charge.

Enrolled consultant · DEWA

Connection application and design approval

The connection request, with load schedules and drawings, is filed and reviewed. Comments on load figures or board schedules are answered with revised documents.

Enrolled consultant or contractor · DEWA

Invoice and payment

DEWA issues an invoice for the applicable connection charges, which the owner pays before the connection proceeds.

Owner

HV inspection, where there is a substation

If the project includes a DEWA substation, DEWA inspects it once the substation room is ready.

Contractor · DEWA inspectors

LV inspection

When the electrical installation and wiring are complete on site, the contractor requests the low-voltage inspection and submits site photos and supporting documents.

Electrical contractor · DEWA

Meters and energisation

With inspections passed and the owner's supply terms signed, DEWA fits the meters and releases the supply. The account is then activated in the occupier's name.

DEWA · owner

Fit-outs follow a shorter version: design approval of the unit's boards and layouts, LV inspection of the installed work, invoice, then supply. Our fit-out approval page shows how this sits beside the authority fit-out permit and Civil Defence.

Load approvals and substation requirements

The load figure is the single most important number in a DEWA file. It drives the size of the incoming supply, the meter arrangement and whether DEWA needs space on the plot for its own equipment.

DEWA's regulations for electrical installations require space for a DEWA substation within the building or plot where the total connected load exceeds 400 kW, and DEWA can ask for one at lower loads in some circumstances. On a mid-size building or a warehouse with heavy cooling, that requirement shapes the ground-floor layout, so it should be settled during concept design rather than after the architecture is fixed.

For existing buildings, added load is where projects slip. An owner adds a pool, a cold room or a large kitchen, and the extra demand is never put to DEWA. The supply may cope for a while, but the installation no longer matches what was approved, and that can surface at a later inspection, at a tenancy change or when the property is sold.

What affects DEWA fees and timing

DEWA lists the building NOC itself as free, and its building NOC page states that, for projects in the building permit system, the NOC is processed within three working days from submission. DEWA also lists short service times for fit-out design approval and LV inspection. These standards apply once a complete application is in, and they don't include the time to design, answer comments or finish the installation.

Connection charges are a different matter. They are invoiced by DEWA according to the load and the type of connection, so we don't quote them as fixed figures. Your quotation from us separates DEWA's charges, paid directly to DEWA, from our consultancy fee.

What keeps a DEWA file moving

Load calculated early and agreed with the architect
Board schedules that add up to the declared demand
Substation space allowed for where the load requires it
LV inspection booked only when the site is truly ready

What adds time

Schedules that contradict the single-line diagram
Missing landlord NOC on a fit-out
An expired building NOC that must be re-applied for
Failed inspection because of incomplete wiring or labelling

Validity matters too. DEWA's service guide gives the electricity building NOC two years in normal growth areas and one year in major project areas for the follow-on connection application. A project that stalls can find its NOC lapsed when it restarts. For a fuller timeline across all authorities, see how long a building permit takes in Dubai.

Common DEWA problems and how to avoid them

Sizing the load from a rule of thumb. A load guessed from floor area rather than calculated from the actual equipment is often challenged, or turns out too small once tenants move in. Work from the real cooling and equipment schedules.
Fit-out boards that don't fit the base building. A tenant's design must sit within what the landlord's approved distribution can supply. Check the spare capacity allocated to the unit before designing.
Forgetting the water side. Tank position, meter location and the connection route all appear on the water application. Late architectural changes can move them.
Digging near DEWA assets without clearance. Cables and pipes run under roads and plot edges. Excavation near them needs DEWA's no-objection, and often an RTA right-of-way permit too. See our RTA approval service.
Treating DEWA as the last step. The building completion certificate and DEWA's final connection are linked, so loose ends in either hold up occupancy. Our completion certificate page explains that stage.

How we help with DEWA approvals

Most clients come to us either at design stage, when they want the DEWA side planned properly, or near handover, when a connection has stalled. In both cases we:

Review the load calculation, board schedules and drawings for consistency before anything is filed
Confirm which DEWA service applies, and whether the request goes through the municipality's system or DEWA directly
Prepare the setting-out plans, layouts and landlord NOC wording DEWA expects
Coordinate submission through a DEWA-enrolled consultant or contractor where required
Track comments and invoices, and plan inspections with the electrical contractor
Bring DEWA into a wider plan with other authorities through our NOC coordination service

DEWA approval FAQs

Can a property owner apply to DEWA directly for a building NOC?

DEWA's building NOC and connection services are designed for enrolled consultants and contractors. For Dubai Municipality projects the NOC request goes through the municipality's building permit system. The owner provides ownership documents and signs DEWA's supply terms before the supply is released.

Does DEWA charge for the building NOC?

DEWA lists the building NOC for electricity and water as free of charge. Connection charges and other invoices are separate and depend on the load and the type of connection.

I am fitting out a shop. Do I need DEWA approval?

Usually, yes. A fit-out connection needs the unit's distribution board schedules and lighting and power layouts approved, a landlord NOC in DEWA's format, and an LV inspection of the installed work before supply is released to the unit.

When does a building need a DEWA substation?

DEWA's electrical regulations call for substation space within the plot or building where the total connected load exceeds 400 kW, and DEWA may ask for one at lower loads in some cases. Your MEP consultant should confirm this at concept stage.

Are you part of DEWA?

No. We are a private consultancy. DEWA alone approves loads, inspects installations and connects supply. We prepare and coordinate the applications.
