DEWA approval in a Dubai fit-out: when you need a load increase

What DEWA approves in a fit-out, and what it leaves to someone else

DEWA owns the supply up to and including your meter and reviews the installation downstream of it against the DEWA Regulations for Electrical Installations. That is the whole of its interest. Whether your reception looks good or the sprinkler heads are spaced correctly is not DEWA's file, and neither is whether the kitchen can legally serve food.

Tenants tend to assume they are already in the cheapest of the routes below.

Account activation is the simplest. The premises already has a meter and a supply, the previous occupier closed the account, yours opens, no design review.

A fit-out power connection is DEWA's named builder service for shops and offices, free of charge as a service. Your enrolled contractor submits the electrical drawings, DEWA reviews them, an inspector attends site before the meter goes in. DEWA's service guide puts design approval at a minimum of one working day and the low voltage inspection appointment within two working days of the readiness date the contractor notifies. Those are processing steps in isolation rather than the calendar you will experience, because the readiness date depends on when your installation is actually finished and correct.

A network modification is the expensive route. The supply itself changes: a bigger cable, a different tariff metering arrangement, an additional meter, sometimes a substation. The application is free to lodge and the works are chargeable. DEWA prices them by issuing an estimate, notified by SMS or email, and nothing gets built until that estimate is settled.

One thing catches almost every tenant in a modern tower. Your air conditioning may not be a DEWA load at all. Where the building runs on district cooling, the cold arrives as chilled water from Empower or Emicool, and extra capacity is a commercial conversation with that provider under the building's allocation. Tenants who budget an HVAC upgrade as a DEWA item usually find the real constraint is the chilled water allocation written into the base build.

Load increase or new connection: work out which one you are in

A new connection means the premises has no usable supply in your name. Shell and core units, a new plot, a floor subdivided into two tenancies where only one meter exists. You are asking DEWA for a supply that does not currently terminate where you need it.

A load increase means the supply exists and you want more out of it. What decides this is the maximum demand on your load schedule after diversity, set against the load already allocated to that unit in the approved base build documents, not your appliance list.

Finding that allocation takes a day and belongs at the start of the project. The landlord or building management holds the base build electrical drawings. The previous approved load schedule, if the last tenant did a fit-out, tells you what DEWA last signed off. The distribution board in the unit tells you the incomer rating. Put those next to your proposed schedule and you know whether you have a conversation or a problem.

One threshold is worth knowing before anything gets designed. DEWA's regulations state that where total connected load exceeds 400 kW, provision has to be made within the building or plot for a DEWA substation, and they are explicit that one can be required below that figure too. Under 400 kW the meter location goes on the setting out plan and the process stays comparatively light. Over it, you are into space planning, because a substation needs a room at ground level with vehicle access, and in a leased unit that room usually does not exist and cannot be created.

The practical version: if your demand fits inside the existing allocation, the programme has one fewer external dependency. If it does not, the load application goes on the critical path in week one.

Temporary power while the work is running

Nobody builds a fit-out on a battery. Tools, task lighting, site welfare and eventually the commissioning of everything you installed need power, and the permanent supply is usually the last thing to arrive.

In a tower or a mall the answer is normally the landlord's builder supply. The base build has a temporary distribution board, you take a connection off it with a sub meter, and the fit-out manual sets the rules and the recharge rate. No DEWA application, because you are consuming through the building's existing account.

In a standalone unit, a shell and core plot or a warehouse with no live supply, you need your own construction supply from DEWA. The guidance for builders is to submit construction and permanent supply together rather than sequentially, and it is worth following: the two applications draw on the same technical package, and the reviewer sees the whole project instead of half of it. The construction submission expects a project and plot summary, load calculations including the number of kWh meters at main low voltage panel level, a single line diagram of the proposed low voltage distribution, and a site setting out layout showing where the substation, the low voltage room, the meter and the main distribution board sit.

Construction power is metered and billed to you, which on a long fit-out with heavy machinery is a line item rather than a rounding error, and it is easy to miss when nobody owns that invoice. Commissioning is where temporary power stops being enough: air balancing, lighting scenes, kitchen equipment under load and any testing witnessed by an authority want the permanent supply live and stable. Sequence energisation to land before commissioning starts, not during it.

Unit type changes almost everything

The generic fit-out approval guide treats all premises the same. In practice the difference by use is enormous, and it comes down to how much power the operation draws and how late the equipment schedule gets fixed.

| Unit type | What drives the load | Usual DEWA route | Where it stalls |

|---|---|---|---|

| Office on a Cat A floor | Small power, comms room, kitchenette, fan coils for cellular rooms | Activation, or a fit-out connection if boards change | Floor board already at capacity from the last tenant |

| Restaurant or café | Cooking line, extraction and make up air, cold rooms, water heating | Load increase in most cases | Kitchen equipment schedule lands after submission |

| Clinic | Imaging, sterilisers, medical air and vacuum, UPS, clean circuits | Load increase, alongside the health authority licence | Equipment models not fixed, so the schedule is a guess |

| Retail unit in a mall | Track and feature lighting, signage, fitting room cooling | Fit-out connection under the landlord's manual | Landlord's per unit capacity, set years earlier |

| Warehouse or light industrial | High bay lighting, cold storage, charging bays, machinery | New connection, sometimes with a substation | Passing 400 kW with no room for one |

Restaurants are the reliable trouble case. Cooking line, extract fan, make up air unit and cold rooms together often exceed everything the unit was ever supplied for, and the kitchen equipment schedule is the last document anyone produces because the operator is still negotiating with suppliers. A load application built on placeholder equipment is one you will be resubmitting. The rest of that approvals chain has its own difficulties, covered in our guide to restaurant kitchen fit-out, extraction, gas and Food Control.

Clinics have the same problem wearing a lab coat: imaging equipment, autoclaves and any UPS backed clean supply have to be specified before the electrical design is final, while the health authority approval runs its own cycle in parallel. Offices are the easiest case by a distance, which is why so many office fit-outs complete without anyone in the tenant's team hearing the word DEWA. How that sits in the wider programme is on our office fit-out page.

The submission pack, and who puts their name on it

Only enrolled parties can submit. Enrolment with DEWA as an electrical consultant or contractor requires a valid trade licence and at least one graduate electrical engineer under the company's sponsorship with a minimum of one year supervising or designing electrical works in compliance with DEWA regulations. A tenant cannot lodge this personally, and neither can a contractor who is not enrolled, whatever he tells you about a partner who can handle it.

| Document | Who produces it | What gets it rejected |

|---|---|---|

| Connected load and maximum demand summary | Electrical consultant | Diversity applied optimistically, so demand reads smaller than the installation |

| Single line diagram with low voltage distribution and tariff metering | Electrical consultant | Board ratings and protection that contradict the load schedule |

| Load distribution schedules for final distribution boards | Electrical consultant | Circuits on the layout that never reached the schedule |

| Setting out plan with meter location | Consultant, with the contractor | Meter where DEWA cannot reach it, or where joinery lands on it |

| Affection plan, current issue | Owner or landlord | Superseded version, or missing where the plot sits in a free zone |

| Architectural layout used as the background | Interior designer | A revision the client already replaced |

| Equipment schedule with actual ratings | Tenant and operator | Placeholder models, or ratings copied off a similar project |

The right hand column is the whole story: the pack fails as a set far more often than any single sheet fails alone. DEWA's reviewer reads the drawings against each other, and internal contradiction is the fastest route back to your inbox.

Why load applications come back

Rejections are boring and repeatable, which is good news, because repeatable means preventable. What we check before anything is lodged:

One more sits outside the pack. Al Sa'fat, Dubai's green building system, is administered by Dubai Municipality rather than DEWA, while DEWA maintains its own Green Building Regulations and Specifications covering matters such as lighting power density. Teams sometimes design a lighting scheme and then discover a compliance requirement attached to a different authority than the one they were talking to. Ask which green building obligations attach to your premises before the lighting design is fixed.

• Does the single line diagram agree with the load schedule, circuit for circuit and rating for rating? Most common failure by a wide margin, and it comes from two people editing different files on different days.
• Is the maximum demand honest? An understated figure gets approved, then trips repeatedly once the tenant actually operates, and the correction is a second application after you have already built.
• Is every drawing stamped by the enrolled consultant, and is that enrolment current?
• Is the architectural background the current revision? Walls that moved three weeks ago invalidate the circuit positions drawn on top of them.
• Can the meter physically go where the drawing says, with access for reading and maintenance and no joinery built across it later?
• Has the equipment schedule been signed off by whoever will operate the space? In kitchens and clinics this is the item that changes after submission.

The inspection before the meter goes live

Design approval is a paper exercise. Energisation is not. Before DEWA releases a supply, an inspector attends and looks at the physical installation against the approved drawings.

What gets examined is the boring, safety critical half of an electrical installation. Earthing and bonding. Earth leakage protection and its ratings. Cable sizes against the design they were supposed to follow. Board labelling and circuit identification. The meter position, its accessibility and its enclosure. Separation of services in the ceiling void. Protection ratings wherever the installation meets water, which in a restaurant means the wash up area and in a clinic means the sluice.

The security deposit is settled before the meter is installed and the connection released, and DEWA sets that figure against the premises and the account rather than by a flat rate for every tenant. Treat it as a known cost with an unknown number until the application tells you.

After energisation the file is not closed. A completion certificate and as built approval confirm that what was built matches what was approved. Leaving that open becomes a problem at handover, at licence renewal, or on the day you try to assign the lease.

The inspection is fast when the installation is genuinely ready and slow when it is not, because a failure costs you the remedial work plus a new appointment. Contractors who call for inspection to show progress rather than because the work is finished lose more days than they save.

How DEWA lines up against the other approvals

Fit-out approvals in Dubai are not a queue. They are several queues running at once, and the skill is knowing which one blocks which.

The building permit for the fit-out comes from Dubai Municipality, or from the authority that governs your area: Dubai Development Authority for its zones, Trakhees for Jebel Ali, the Palm and the port areas, DIFC and DMCC for their own districts. That process is a topic of its own and we cover it in the guide to the Dubai Municipality building permit for a fit-out. Civil Defence reviews the fire systems. Food Control reviews kitchens. The health authority licenses clinics.

DEWA runs independently of all of them and is the utility in every one of those districts, free zones included. It does not wait for Civil Defence and Civil Defence does not wait for it. The calendar links them, not the paperwork: your electrical installation has to be complete before DEWA will inspect it, and it is not complete until the works the other approvals permit are built.

So the sequencing that works on site. Lodge the DEWA load application in the same week as the building permit submission, because it is the item with the least predictable duration and the least ability to be accelerated by anyone's relationship with anyone. Build under the permit. Book the inspection when the installation is genuinely finished and tested, and put energisation before commissioning rather than during it. Fit-outs that miss their opening date rarely miss it because of the fit-out. They miss it because power arrived after the equipment did.
