DEWA approvals FAQ

Start with the building's own consent, because the landlord or master developer controls access, approved load and fit-out rules. Then submit the DEWA electrical package before energisation; Civil Defence and Municipality reviews usually run alongside the fit-out permit, not after it. The exact order depends on the building and activity, so the route sheet should name the dependency for each approval.

Work backwards from the opening date, not forwards from the tenancy signature. The electrical design needs to be reviewed before the installation is built; the inspection needs an inspection-ready site; the meter release needs a passed inspection. If the contractor is appointed late, the approval becomes the critical path. A route sheet with dependencies is more useful than a single “how long” answer.

Possibly. A layout change can alter lighting, air-conditioning, kitchen equipment, socket circuits or egress lighting, and those changes affect the approved load and distribution. If the electrical design, load or supply arrangement changes, expect a revised submission. Cosmetic work with no electrical change may still need landlord and fit-out permits, so compare the scope against the approved drawings before deciding.

The application should be supported by the tenancy evidence the authority and landlord require. An unregistered or inconsistent tenancy can create a mismatch between the applicant, the premise and the licence. Check the contract's unit number, owner, tenant and validity against the trade licence before submission. If the contract is being renewed or transferred, resolve the mismatch first rather than attaching an explanation later.

The submission should be legible at the scale it is reviewed, with a title block that names the project, sheet, revision and date. Use a consistent sheet numbering system and make the file names match the transmittal. PDF is the review format; keep the native drawing available for revisions. The exact scale and format depend on the service and the authority's current portal requirements.

Typically the tenancy contract, trade licence, landlord or developer NOC, authorised signatory letter and the unit's approved drawings. DEWA may also ask for the premise or customer number, a load schedule and a single-line diagram. Requirements vary by service and property, so the transmittal should list every document by title, revision and date rather than relying on a generic checklist.

Connected load is the sum of the installed equipment ratings you declare. Maximum demand is the diversified load you expect after applying demand factors; it is the figure that drives supply capacity and protection. A DEWA submission should show both, with the calculation method and the assumptions behind each demand factor. Oversizing without justification invites comments; undersizing creates a real operational risk.

The SLD should show the earth path from the point of supply through the main earth bar, the main protective bonding and the final circuits, with the protective device ratings and ratings of the earthing conductors. It should also identify the type of earthing system and any equipotential bonding. A note that says “earthing as per regulations” is not a design detail; draw the relationship.

LV usually means supply at 400/230 V three-phase or 230 V single-phase. HV starts at 11 kV in Dubai's distribution context and is used for larger developments, dedicated substations and some industrial sites. The line is not just about total kW: the authority's network, the building's existing infrastructure and the space available for a substation all decide the connection type.

Do not assume that the water connection and the drainage connection sit in the same application. The responsibility depends on the property, the network and the authority with jurisdiction. Check the connection point, the internal plumbing boundary and the building permit conditions before you submit. A route sheet should name the authority for each utility, not just the utility type.

The meter size follows the expected flow and the plumbing design, not the unit's floor area. Fixture units, simultaneous demand, storage, pressure and the internal pipe size all matter. A restaurant, clinic and office with the same area can need different arrangements. The design should show the demand calculation and the proposed meter position before the application is sent.

A temporary connection is sized for construction demand, has a defined duration and may use a different meter and protection arrangement from the permanent supply. It should not be treated as a placeholder for the final connection. The site plan needs to show the temporary point, the backflow protection and how the permanent connection will replace it without disrupting the works.

Statuses describe where the file sits in the authority's workflow. “Submitted” means it is queued; “under review” means an engineer has it; “comments” means a response and revised documents are required; “approved” means the design or NOC has passed that stage. A status is not a date promise. Keep the transmittal, comment sheet and revision table together so the next action is traceable.

Answer each comment in the same order, quote the comment, name the changed sheet and revision, and state the technical basis for the change. Do not send a clean drawing set without a response sheet; the reviewer should not have to hunt for the change. If a comment is not accepted, explain why with the calculation or the standard, rather than repeating the original drawing.

It is the identifier the authority uses to link the application to the property and the supply account. You normally find it on a DEWA bill, the connection document or the landlord's handover pack. If the unit is new or the number is unclear, resolve it before submission; an application that points to the wrong premise can be delayed or rejected even when the drawings are correct.

Government fees respond to the service, supply size, number of meters, asset works and whether the connection is temporary or permanent. They are not a consultant's fee. Ask for a fee breakdown that separates authority charges, deposits, consultant work and contractor works, and confirm which deposits are refundable. Rates change, so the quotation should state the date and source used.

The government fee is the authority's charge for the service. The consultant fee pays for the design, submission, comment responses and inspection support. The contractor's price covers the physical installation and tests. Mixing them into one headline number hides who carries the risk. A good quotation separates the three and states which items are pass-through, which are fixed and which are provisional.

A realistic programme is built from dependencies, not a single published duration. The main variables are design completeness, landlord consent, authority review cycles, contractor readiness, inspection defects and meter release. The largest avoidable delay is usually a design that does not match the site or the equipment. A dated route sheet with owners and outputs is more reliable than a generic promise.

Clear access, safe isolation, labelled boards, as-built drawings and the test pack should be ready before the inspector arrives. The installation should match the approved SLD and load schedule. Common failures include incomplete labelling, missing test results, unprotected circuits and a meter position that cannot be accessed. A pre-inspection walk with the contractor is cheaper than a second slot.

The test pack should cover insulation resistance, earth-loop impedance, RCD operation, polarity and continuity where applicable, with the instrument, calibration and tester identified. It should also include the schedule of circuits and the board labelling. The exact set depends on the installation and the authority's current requirements; the important point is that the results are traceable to the boards they test.

No. Each free zone or master developer can add its own permit, NOC, access and utility interface before or alongside the DEWA application. The technical design may be similar, but the submission route and the authority contacts are not interchangeable. Start with the zone's fit-out guide and the landlord's utility handover, then map the DEWA file into that sequence.

A villa in a master community can need the developer's NOC, design review, access permit and construction rules in addition to the DEWA connection or building NOC. The community may also control the meter position, landscape works and the contractor's site facilities. Treat the developer's guide as a prerequisite document, not an afterthought once the DEWA file is ready.

Often, yes. Larger industrial loads can require an HV design, a dedicated substation, a different metering arrangement and a longer inspection. The building's power quality, motor starting, process equipment and future expansion also affect the design. The fit-out route may still apply to the office and welfare areas inside the same building, but it should not be assumed to cover the industrial supply.

Ask for the legal entity, the registration number and the scope the registration permits, then check it against the authority or regulator's published register. A logo, a website or a claim of “approved” is not evidence. The check should match the entity that will sign the application, not a trading name or a subcontractor. Keep the verification in the project file.

Do not hide the installation or backdate a drawing. Start with an as-built survey of what exists, compare it with the approved design and the supply, and identify the non-compliant items. The remedy may be a revised submission, a rectification scope, a new inspection or a combination. The earlier the real condition is documented, the lower the risk of a failed inspection or an unsafe energisation.

The consultant should state what it collects, why, where it is stored, who can access it and how long it is retained. Drawings, licences and contact details should be stored in access-controlled systems, not personal email inboxes. Ask for the privacy notice and the retention period before uploading. This answer is a policy statement, not legal advice; the production notice will be reviewed by counsel.

The tenancy, trade licence, landlord or developer NOC, existing supply details, approved drawings and the proposed equipment list. If the drawings are not ready, send the architectural layout and the equipment schedule; we can tell you what is missing. A short note on the opening date and the contractor's appointment helps us build the route in the right order.

The production service will agree a written update rhythm at the start, with a named contact and a status log. Updates should record the last action, the next action, the owner and the date, not just “under process”. Authority status changes and comment rounds should be sent with the source document attached. Weekend and out-of-hours cover must be confirmed, not assumed.

Arabic and English project communication is planned, with the site mirroring the English content in Arabic. Weekend cover and response times are not published in this prototype; the production answer will state the actual desk hours, languages and escalation contact after the owner confirms staffing. Do not assume a 24/7 service from a design mock-up.

A fixed-scope fee is appropriate when the documents, route and number of review cycles are known. The quotation should list inclusions, exclusions, pass-through authority fees, deposits and the payment milestones. If the scope changes because the equipment or property changes, the fee should be varied in writing, not absorbed silently. The production page will state the actual policy and terms.
