A building in Dubai can be finished, inspected and approved by the planning authority and still sit without permanent power and water. The missing step is usually DEWA: the as-built drawings, the final inspection of the electrical and water installation, and the documents that let DEWA energise the building and open customer accounts.
This guide explains how the DEWA side of completion works: what as-built drawings DEWA expects, who prepares and signs them, how DEWA's completion links to the authority's completion certificate, and how to avoid the delays that leave finished buildings on temporary supply. It applies to new buildings, extensions and fit-outs with new or increased loads.
For end-to-end support, see our DEWA approval services.
The short answer
When the electrical and water installation is complete, the DEWA-enrolled consultant and contractor prepare as-built drawings that show the installation as actually built. Both the consultant and the contractor approve them before submission. DEWA reviews the as-builts, inspects the installation and, once satisfied, completes its side of the project so the building can be energised and connected. On the Dubai mainland, Dubai Municipality's completion certificate is what enables service connections, so the two processes run together. Leaving DEWA completion open after the building is occupied can lead to DEWA blacklisting the consultant or contractor, which blocks their future applications.
Where DEWA completion fits in the project
- Design stage: DEWA NOC and load approval, usually issued within the building permit package.
- Construction: installation by a DEWA-enrolled contractor, supervised by a DEWA-enrolled consultant.
- Testing: the contractor tests the installation and prepares test certificates.
- As-built submission: as-built drawings approved by consultant and contractor are submitted to DEWA.
- DEWA inspection: DEWA inspects the installation against the approved and as-built drawings.
- Authority completion: the planning authority's completion certificate is issued, with DEWA's requirements satisfied.
- Connection and accounts: permanent supply is energised and customer accounts are opened.
For the design-stage steps, see our DEWA approval process guide.
What DEWA as-built drawings should show
As-built drawings record the installation as it was built, not as it was designed. DEWA uses them to check what has been connected and to maintain its records. They should show:
- Electrical single-line diagram with the final ratings of incoming supply, main switchgear, distribution boards and cables.
- Load schedules showing connected loads per board, matched to the approved load.
- Layouts of the main LV room, meter locations and riser routes.
- Substation details where the building has its own substation, including access and ventilation.
- Water supply layout, meter positions, tanks and pumps where DEWA requires them.
- Any changes from the approved design, clearly identified.
Where the installation differs from the approved design, the difference has to be accepted by DEWA. Significant increases in load usually need a revised load approval before completion.
Who is responsible
- Consultant: supervises the installation, checks the as-builts and approves them for submission.
- Contractor: installs, tests, prepares the as-builts and test certificates, and approves the as-builts.
- Owner: pays fees and deposits, and coordinates access and account opening.
- DEWA: reviews, inspects and connects.
Both the consultant and the contractor must be enrolled with DEWA for the relevant work. Because both sign the as-builts, both are accountable if the drawings don't match the installation.
Linking DEWA with the completion certificate
Dubai mainland
Dubai Municipality's completion certificate is the document that allows DEWA and other service connections. DEWA's requirements, including the as-builts and inspection, need to be satisfied for the building to be connected. Our guide to DM villa building permits and completion certificates explains the municipality's side.
Other jurisdictions
In DDA, Trakhees and other areas, the local authority issues the completion certificate under its own process, but DEWA's as-built and inspection requirements still apply wherever DEWA supplies the building. Check the sequence with the local authority at the start of the project.
The blacklisting risk
DEWA expects completion to be closed properly. Where a building is occupied or used without the DEWA completion steps being finished, DEWA can blacklist the consultant or contractor responsible. A blacklisted company cannot submit new DEWA applications until the issue is resolved, which affects every other project it is working on. For consultants and contractors, closing DEWA completion is a business risk, not just a project task.
Fit-outs and load increases
Fit-outs usually connect to the existing building supply. If the fit-out stays within the unit's allocated load, DEWA's involvement may be limited. If it increases the load, needs a new meter or changes the main installation, a DEWA application, as-builts and inspection are required. Restaurants, gyms, clinics and data rooms often increase load, so check early.
Before handover, confirm in writing with the tenant or owner which loads will be connected on day one, and compare them with the approved figure. A short load reconciliation at this stage avoids the most common inspection finding and gives everyone a clear record of what was approved and what was built.
Common reasons DEWA completion is delayed
- As-builts that don't match the site, found at inspection.
- Connected load above the approved load without a revised approval.
- Substation not ready, with access, ventilation or civil works incomplete.
- Test certificates missing or incomplete.
- Unpaid fees or deposits holding up energisation.
- Authority completion and DEWA completion not coordinated, so each waits for the other.
A DEWA completion checklist
- Compare the installed system with the approved drawings and load.
- Get revised approval for any load or design change.
- Prepare as-built drawings and load schedules.
- Have both consultant and contractor review and approve the as-builts.
- Complete testing and assemble the certificates.
- Make sure the substation and LV room are complete and accessible.
- Submit the as-builts and book the DEWA inspection.
- Coordinate with the authority's completion inspection.
- Pay fees and deposits, then open accounts.

Temporary supply vs permanent connection
During construction, sites usually run on temporary supply or generators. Temporary supply is not a substitute for completion. It is approved for construction use, and its conditions do not cover an occupied building. Moving to permanent supply requires the as-builts, the inspection and the completion documents. Owners who plan handover dates around temporary supply often find tenants ready to move in with no permanent connection available. Build the DEWA completion steps into the handover programme from the start, with the as-built preparation starting while final works are still underway.
Preparing as-builts during construction
The best as-builts are prepared progressively, not reconstructed at the end. Ask the contractor to mark up changes on a site set as they happen, with cable sizes, board positions and routes recorded when they are installed. At the end, the as-built set is a clean-up of the mark-ups, not a survey. This also gives the consultant a chance to spot changes that need DEWA approval while they can still be corrected.
Multi-tenant buildings
In buildings with many units, DEWA completion for the base building and for each tenant's connection are separate steps. The base building's as-builts and completion come first. Tenant connections then follow through each tenant's account and, where loads change, their own applications. Landlords should keep the base building as-builts available to tenants' consultants, since every tenant fit-out relies on them.
Villas and small buildings
For a private villa, the DEWA steps are the same in principle but smaller in scale. The contractor prepares the as-built single-line diagram and load schedule, the consultant approves it, DEWA inspects the main board and meter position, and the connection follows Dubai Municipality's completion certificate. Typical villa issues include meter cabinets placed differently from the approved site plan, boundary wall works that block meter access, and extra loads such as pool equipment, outdoor kitchens or additional air-conditioning units added after the design load was approved. Each of these is easy to correct before the inspection and slow to correct after it.
Solar and other generation
Buildings with rooftop solar connected to the grid follow DEWA's distributed renewable generation requirements, which have their own approvals and inspections. Treat them as a separate workstream with its own as-builts. Coordinate the timing so the solar inspection does not hold up the building's main connection, or the other way round. Check DEWA's current requirements before design, since these programmes are updated from time to time.
