Interior design contractors in Dubai: how to choose one

What licences interior design contractors in Dubai actually need

Start with the trade licence, and read the activities, not the letterhead. A licence issued by Dubai's Department of Economy and Tourism lists the specific activities the company may perform. "Interior Design Services" is a design activity. Executing the work on site needs a contracting activity, typically along the lines of interior decoration contracting, building contracting or one of the trade-specific contracting categories.

A company holding only a design activity can draw your office beautifully and cannot lawfully build it. It will subcontract, which is not automatically a problem, but it changes who carries the risk and who you chase when a wall lands 200mm out.

Check the expiry date. Check that the legal name on the licence matches the name on the quotation, the contract and the bank details. Where those three do not match, stop and ask why before anything else.

Then check the licence's jurisdiction against your unit's jurisdiction. A free zone licence and a mainland unit are not automatically compatible. Which authority governs your premises decides the whole approvals route, and it varies by building: mainland offices generally sit with Dubai Municipality, free zone areas fall to their own authorities, and parts of Palm Jumeirah, Jebel Ali and the port areas fall under Trakhees. We have run submissions for offices in Platinum Tower in JLT, restaurants on Sheikh Zayed Road and a retail unit inside Dubai Hills Mall, and no two of those followed the same paperwork path. If you are unsure which regulator owns your unit, our breakdown of which authority approves what in Dubai sorts it by location and project type.

Beyond the licence, three registrations matter for anything structural or permit-bearing:

Work on partitions, layout changes or anything touching the base building services on the mainland needs the Dubai Municipality permit issued before work starts. A contractor who suggests starting quietly and regularising later is telling you how the rest of the job will be run.

• Registration in Dubai Municipality's permit system. A contractor has to be registered and classified to be named on a building permit application. Classification grades limit the value and type of work a company may take on.
• A consultant of record. Drawings submitted for a Dubai Municipality permit have to be produced and stamped by a registered engineering consultant, with the signing engineer qualified through the Society of Engineers route. Ask who that consultant is by name. Ask whether they are in-house or engaged per project.
• Dubai Civil Defence approval for fire-related works. Fire alarm, sprinkler modification and suppression work sit with contractors approved by Civil Defence for those systems. If your layout changes a single sprinkler head position, this becomes your problem, not a footnote.

A ten-minute check on any interior contractor in Dubai

This is the version you can do from your desk, before you invite anyone to site.

1. Ask for the trade licence as a PDF. Read the activity list and the expiry date. Verify the licence number through the Department of Economy and Tourism's public licence check.

2. Match the entity. Licence name, quotation header, contract party and bank account holder should be one legal person. Three out of four is a problem.

3. Ask which authority governs your unit. A contractor who has worked your building type will answer in one sentence. Hesitation here is informative.

4. Ask for a permit number from a job they finished in the last twelve months, in the same jurisdiction as yours. Not a photograph of a finished office. A permit number.

5. Ask who the consultant of record is and who stamps the drawings.

6. Ask for current insurance certificates. Contractors all risk and public liability, with validity dates that cover your programme. Read the dates.

7. Ask who the site engineer will be, whether he is employed by them, and how many projects he is running in parallel while running yours.

8. Ask to see the last snagging list they closed out. A contractor willing to show you a document listing their own defects and the sign-off against each one is showing you how handover works with them.

Points four, five and eight are the ones that thin the shortlist. Interior design and fit out companies in Dubai that mostly broker work to subcontractors tend to go quiet on all three.

Design-build under one contract, or a designer and a contractor separately

Both models work. They fail differently, and the failure mode is what you are choosing between.

One contract, design and build. The same company draws the office and builds it. When the drawing turns out to be wrong, correcting it is their cost, because they authored it. Coordination gaps between design and site mostly disappear, and so does the argument about whose problem an unbuildable detail is. The trade-off: you have given up an independent party checking the builder's work, so the quality of the contract and the clarity of your specification carry more weight. Our own process walks through how a single-contract job runs from survey to handover.

Designer and contractor separately. You get design intent protected by someone with no interest in cheapening it, and independent supervision during construction. You also own the gap. When the ceiling detail assumed a void that contains a beam nobody surveyed, the designer says the contractor should have raised it, the contractor says he priced what was drawn, and the conversation is billable to you in both time and variations.

On larger jobs a third arrangement appears: designer, main contractor and the client's own project manager holding the middle. It works, and it costs more in fees. Below a certain project size those fees buy less than the same money spent on a longer, better-written scope of works.

Whichever model you pick, three things go in the contract in writing:

That third clause is the one that decides how the last three weeks of the project feel.

• who submits to the authority and who pays for a resubmission after comments
• who owns dimensional accuracy on site against the drawings
• what happens, commercially, when a designed element cannot be built as drawn

What moves the price of an office fit-out

We do not publish a per-square-foot rate on this site, and we would treat any that you find elsewhere as marketing rather than as a budget. A single rate has to assume a shell condition, a partition ratio, an MEP scope and a landlord's rules, and if any of those four assumptions miss, the number is off by a margin that matters. Two identical floor plates in the same tower price differently depending on what the previous tenant left behind.

What the number is actually built from:

To make bids comparable, issue every contractor the same drawing set, the same scope of works and the same exclusions template, then compare line by line rather than by total. Our office fit-out page sets out what we include as standard on a Cat B office, and if you want a figure against your own unit rather than against a generic square metre, send the plan and the lease through the estimate form.

• The condition you are taking the space in. Shell and core means no ceiling, no flooring, no distributed services. Cat A means the landlord has delivered a finished but generic space: raised floor or screed, ceiling grid, base lighting, primary HVAC distribution, sprinklers and fire detection to an open-plan layout. Cat B is your fit-out on top of that, and it is what most tenants are actually buying. A previously fitted unit sounds cheaper and often is not, because strip-out and making good arrive first.
• Partition ratio. Cellular offices cost more per square metre than open plan, and glass partitions cost more than blockwork or drywall. The number of rooms drives doors, ironmongery, ceiling breaks, lighting circuits, sprinkler heads and air terminals, and each of those multiplies quietly.
• How far the MEP moves. If your plan sits comfortably under the base build FCU layout and the existing power density carries your headcount, MEP stays modest. If you are relocating rooms across the plate, the ducting, the diffuser layout and the fire detection follow, and the fire strategy change pulls Civil Defence into the programme.
• Joinery volume and specification. Reception desks, storage walls, pantry units and boardroom tables are usually the single largest variable line, and the one most often left as an allowance in early quotations.
• The landlord's fit-out manual. Permitted working hours, out-of-hours charges, service lift booking, hoarding specification, insurance limits, deposits and reinstatement obligations at lease end. Buildings differ sharply. Some manuals add real cost before a single wall goes up.
• Programme. Compressing a sixteen-week job into eleven is bought with double shifts, night work and expedited supply, and it shows up in the price rather than in the drawings.

Contract, payment schedule and retention

The payment schedule tells you more about a contractor than the portfolio does. The full mechanics of a quotation, including the exclusions page and provisional sums, are covered in our breakdown of what a fit-out quotation should contain; what follows is what to watch for while you are still deciding who to hire.

An advance at signature is normal and typically sits somewhere around ten to twenty percent of the contract value. An advance above roughly a third of the contract value is a financing request, not a mobilisation payment, and the usual reason is that the money is needed to finish somebody else's project. Treat it as a stop sign.

Interim payments should attach to verified progress on site rather than to calendar dates. Strip-out complete. First fix MEP complete and inspected. Ceilings closed. Joinery delivered and installed. Payment against dates means you fund delay; payment against milestones means the contractor funds it.

Ask what the retention percentage is and what releases it, at bid stage rather than at handover. It is commonly five to ten percent and negotiated rather than fixed by law, and a contractor who cannot tell you the release condition on the spot has not thought about handover yet.

Separate the defects liability period from the warranty before you sign. The defects liability period is a contract window, often twelve months from handover, during which the contractor returns and fixes what fails. Warranty on workmanship is commonly stated at two to three years, and individual elements (waterproofing systems, HVAC equipment, anything with a manufacturer behind it) carry their own terms.

Variations are where budgets actually go, and the fix is agreed before you sign rather than after. Ask for a rate schedule for common items at contract stage: additional power points, extra partition runs, door sets, additional data outlets. Without one, variations get priced at the moment you have the least leverage, which is the week before handover.

Red flags, and what to ask before you sign

Signs that a contractor should not be on the shortlist:

Questions worth asking every bidder, in this order:

The fourth question is the one office renovation contractors in Dubai least expect, and the answer separates companies that run the approvals queue from companies that watch it.

• No verifiable registration with the authority that governs your unit, or an offer to work under another company's licence
• A scope of works written as a materials list instead of as activities
• Any version of "we can start now and sort the permit later"
• No payment schedule tied to site progress
• An advance above roughly a third of the contract value
• No named site engineer, or a site engineer who turns out to be a freelancer shared across five jobs
• A price well below the others attached to a short exclusions page
• Time pressure attached to a discount
• A warranty that exists only in conversation
• Which authority governs my unit, and when did you last submit there?
• Who is the consultant of record and who stamps the drawings?
• What did you find at survey that is not shown on the drawings?
• If the submission comes back with comments, who carries the cost and time of resubmission?
• Which items are long-lead, and what are their lead times?
• What are the building's permitted working hours, and is your programme built around them?
• Who runs the snagging list, and what is the release condition on retention?

How long an office renovation in Dubai takes

Programme bands we see, measured from contract signature and including the approvals run rather than starting after it. Treat them as planning figures, since the building, the authority and the supply chain all vote.

What stretches a programme, in descending order of frequency: resubmissions to the authority after comments, MEP changes instructed after first fix, and supply delays on long-lead joinery or specialist glazing. A well-run job overlaps approvals with procurement so that the permit and the joinery arrive in the same fortnight. A badly run one treats them as a queue.

Our longer piece on office fit-out timelines breaks each stage down week by week, including where the float actually sits.

If you want the checks in this article applied to your own shortlist, send us the drawings, the lease and the landlord's fit-out manual on +971 56 508 0888. We will tell you which questions your bidders have not answered.

• Small office, single floor, Cat A base, limited partitioning: typically around ten to sixteen weeks.
• Mid-size commercial fit-out: typically fifteen to twenty-five weeks.
• Retail, F&B and clinics: typically twenty-five to thirty-three weeks, because a second regulator joins. A restaurant kitchen adds food control approval, a clinic adds health authority licensing, and a mall unit adds the centre's own fit-out manual and its access restrictions on top of everything else.
