Mechanical, electrical and plumbing contracting across Dubai — air conditioning installation and ducting, DEWA-certified electrical works, plumbing and drainage, fire and life-safety interfaces, AC maintenance contracts, testing and commissioning, delivered by one electromechanical contractor with its own engineers.
Most images are site records from Halo projects; selected HVAC views illustrate equipment and finished air distribution that are otherwise hidden once the ceiling closes. Client names, addresses and contract values are not published without written permission, so the notes below describe the problems each project type presents rather than inventing buildings.
Challenge: A commercial floor plate with a shallow ceiling void already carrying the base-build sprinkler main and structural downstands. Halo approach: Coordinate duct, pipe, tray and sprinkler on a single services drawing before anything is ordered, then set the ceiling grid out against the resolved layout so diffusers and fittings land where the reflected ceiling plan says they should.
Challenge: A distribution board at capacity in premises that could not close, in a building restricting noisy works to evenings. Halo approach: Survey spare ways and incoming supply first, submit the load increase to DEWA, then phase the board works and terminations into notified isolation windows so the business kept trading throughout.
Challenge: A space that had been repartitioned around the original cooling design and no longer held temperature at one end. Halo approach: Re-run the cooling load against the current layout and glazing, reposition and extend the ductwork to suit the new zones, then balance the system and record measured flow at every diffuser.

Halo works as a single MEP contracting company across mechanical, electrical and plumbing services, coordinating the complete package rather than supplying disconnected trades. Take the full MEP scope or the specialist package your premises actually needs — every service is delivered against the same coordinated drawings, programme and project manager.
Electrical contracting is the trade most often subcontracted twice before anyone picks up a tool, and it is the one where that shows. Halo carries out the full electrical scope in-house — distribution boards and sub-mains, containment and small power, lighting circuits and controls, earthing and bonding, and the load calculations behind them. Where the works touch the supply, the drawings go through DEWA rather than around it, and the installation is built to be inspected rather than to be concealed.
Dubai runs its air conditioning eleven months a year, so an HVAC installation that was sized optimistically does not fail quietly — it fails in July. Halo installs split, ducted split, VRF and VRV systems and chilled-water fan coil units, with rectangular and spiral ductwork fabricated to the coordinated drawing, insulated, supported and balanced. Fresh air and extract are designed alongside the supply rather than added once the ceiling is closed, which is where most retrofit ventilation problems begin.
Plumbing is decided by gradients and access, and both are settled before the screed goes down. Halo installs hot and cold water distribution, soil and waste, condensate drainage, water heaters and pumps, and pressure-tests every run before it is buried. Where a fit-out moves a wet area — a new pantry, a relocated WC, a treatment room that needs its own basin — the drainage route is confirmed against the existing stack on site rather than assumed from the landlord drawing, because the landlord drawing is frequently wrong.
An AC installation in Dubai is a load calculation before it is a unit selection. Room volume, glazing area and orientation, occupancy, equipment gain and the fresh-air requirement set the duty; the unit follows from the duty. Halo handles supply and installation of new systems, one-for-one replacement of end-of-life plant, refrigerant pipework and condensate runs, condenser positions and the electrical supply that feeds them, then commissions and balances the system rather than switching it on and leaving.
On a tower unit the mechanical scope is usually chilled water rather than refrigerant: fan coil units, two-port and balancing valves, strainers, insulated pipework on trapeze hangers, condensate falls and the interface with the building’s district cooling supply. That interface is a commercial boundary as much as a technical one, and getting the connection, the BTU metering position and the landlord’s conditions confirmed early is what stops a fit-out stalling two weeks before handover.
A fit-out almost never leaves the base-build fire systems alone. Move a wall and you have moved a sprinkler head, a detector and probably an emergency light. Halo handles sprinkler head relocation and extension, detection and alarm device positions, emergency lighting and exit signage, fire dampers where ductwork crosses a compartment line, and the fire-stopping of every service penetration — then puts the amended drawings through Civil Defence rather than hoping the change goes unnoticed at inspection.
Low current is where a project quietly loses its programme, because it is nobody’s trade and everybody’s dependency. Halo installs the containment, trunking and conduit that carry data, access control, CCTV, intercom and AV, sets out the comms room and its power and cooling, and pulls and terminates structured cabling where it is in scope. Active hardware is normally supplied by your own IT vendor — what matters is that the routes, the containment capacity and the comms room are right before the ceilings close.
Most MEP disputes are drawing disputes. Halo produces the MEP design and shop drawings for the works we build — load and cooling calculations, single-line diagrams, duct and pipe layouts, and the coordinated services drawing that resolves ceiling void congestion before three trades arrive to occupy the same 300 millimetres. Where you already hold a consultant’s design, we work to it and flag the clashes, which is a shorter and cheaper conversation on a drawing than it is on a scaffold.
An MEP installation is not finished when it is installed; it is finished when it is proven. Halo carries out insulation resistance, earth loop and RCD testing on the electrical works, pressure and flow testing on pipework, air balancing and flow measurement at every diffuser, and functional testing of controls and life-safety interfaces. You receive the test results, the as-built drawings and the O&M documentation — which is also what the building, the authority and your next contractor will ask for.
Most MEP problems on a Dubai project are interface problems. The ductwork was designed without the structural downstand. The distribution board sits where a joinery run is now going. The fire dampers were in nobody’s scope because the mechanical contractor assumed the fire contractor had them. Splitting mechanical, electrical and plumbing across separate companies — and splitting all three from the fit-out — creates gaps at exactly the points where the trades have to agree.
Halo delivers MEP design, installation, approvals, commissioning and maintenance as one scope under one project manager, coordinated with the fit-out we are also building.
Discuss Your MEP ScopeLoad and cooling calculations, single-line diagrams, duct and pipe layouts and the coordinated ceiling services drawing are produced as one package.
First fix, containment, ductwork, pipework, boards, second fix and terminations are sequenced by one site team against one programme.
Supply and metering coordination, and the amended fire and life-safety drawings a layout change triggers, are prepared and tracked by us.
Testing, balancing, functional checks, as-builts, test certificates, O&M manuals and an optional maintenance contract close the works out.
Quotes from MEP companies in Dubai almost never compare like for like, because each one draws the scope boundary somewhere different — and on an MEP package the difference is usually hiding in commissioning, fire-stopping and who owns the dampers. These are the five things worth testing on every contractor you shortlist, including this one.
A large share of the MEP companies in Dubai quoting your project will price it, win it, and then place the whole scope with a subcontractor they have not worked with before. Halo’s mechanical, electrical and plumbing teams are our own. That is the difference between a contractor who can resolve a clash on the day it is found and one who has to arrange a meeting about it.
Electrical works that touch the supply, the metering or the load have to be submitted and inspected, not simply installed well. Halo’s engineers prepare and submit the drawings, attend the inspections, and build the installation to the standard that gets signed off first time rather than the one that gets a snag list.
Most MEP failures on a Dubai fit-out are sequencing failures — a duct routed where a bulkhead is going, a diffuser landing on a ceiling grid line, a DB position that a joinery run now covers. Because Halo delivers the fit-out, the gypsum and the joinery as well, the services are coordinated against the architecture instead of colliding with it.
MEP is the line item where quotes stop being comparable, because each contractor draws the boundary somewhere different — who owns the fire dampers, who owns the fire-stopping, whether commissioning is included at all. Halo itemises the scope with stated inclusions and exclusions, and every variation is priced and approved before it is built.
Test certificates, air balancing results, as-built drawings and O&M manuals are part of the delivery scope rather than a request you have to chase after handover — and the team that installed the system is still reachable when it needs its first service.
We review the premises, the existing services, the base-build capacity, the building’s rules for MEP works and whatever drawings, lease or fit-out guide you already hold.
Existing DB capacity and spare ways, incoming supply, ceiling void depth, riser access, drainage positions and whether the base-build cooling can carry your intended layout are confirmed on site.
Load and cooling calculations, single-line diagrams, duct and pipe layouts and the coordinated services drawing are developed into a defined scope and a proposal you can compare line by line.
Supply, metering and load submissions go to DEWA; amended fire drawings go to Civil Defence; the building’s own MEP work permits and access approvals are obtained before mobilisation.
Containment, ductwork, pipework and conduit go in against the coordinated drawing, then boards, units, accessories and terminations follow the fit-out sequence rather than fighting it.
Electrical testing, pressure testing, air balancing and functional checks are completed and witnessed, then as-builts, certificates and O&M manuals are issued with the system.
MEP packages in Dubai generally fall within the ranges below. They are indicative planning figures to help you budget, not a quotation — what your premises actually cost depends on how much of the existing installation is genuinely reusable, whether the incoming supply and base-build cooling can carry your intended layout, and how much ceiling void you have to route services through.
MEP cost in Dubai is driven by the cooling load your glazing, orientation and occupancy actually produce, whether the existing distribution board has spare capacity or the load increase triggers a DEWA application, how far wet areas move from the existing drainage, how congested the ceiling void already is, the system type the layout justifies, and the working hours the building permits.
That is why the ranges above are a starting point rather than an answer. After the site assessment you receive an itemised proposal against a defined scope, with commissioning and fire-stopping stated explicitly, so you can compare it line by line with any other MEP contractor in Dubai.
Square footage sets the ductwork and pipework; the number of power, data and lighting points sets the electrical. They do not scale together.
Glazing, orientation, occupancy and equipment gain set the duty. A VRF system, a ducted split and a chilled-water FCU solution to the same duty carry very different costs.
Whether the incoming supply and distribution board can carry the new load — or whether the load increase triggers a DEWA application — is often the largest single variable.
Every new wet point needs a route to the stack at a workable gradient. Reusing a drainage position is inexpensive; moving one across a floor plate is not.
A shallow or already-crowded void forces smaller duct sections, more offsets and more coordination time, and sometimes a different system type entirely.
Towers that restrict noisy or hot works to evenings and weekends stretch the programme and change the rate. This is confirmed with building management, not assumed.
The phase ranges below are what we plan against on a Dubai MEP package. On most projects the critical path is procurement rather than installation — VRF outdoor units, switchgear and bespoke ductwork carry the longest lead times, which is why ordering starts as soon as the design is fixed. You receive a dated programme once the premises, the system type and the building’s access rules are confirmed.
Phases overlap. Procurement runs alongside approvals, and second fix begins before first fix finishes across the whole floor — the sum of the ranges above is not the project duration.
Handing a contractor your electrical supply, your cooling and your drainage is a question of trust, and most of it will be concealed behind a ceiling within weeks. These are the commitments that sit around the work itself.
A line-by-line MEP scope with stated inclusions and exclusions is signed before anyone accesses your unit — including who owns the fire dampers, the fire-stopping and the commissioning, which is where comparable quotes stop being comparable.
Payments are staged against defined, inspected milestones — first fix complete, plant installed, commissioning witnessed — rather than calendar dates, so you are never paying substantially ahead of the installed work.
One person owns the MEP package from survey to handover, coordinates every trade, permit and delivery slot, attends the inspections, and is the number you call.
Halo submits as a licensed contractor, so DEWA, Civil Defence and building management receive documentation in the format they require the first time rather than returning it.
Insulation resistance, earth loop, RCD, pressure and airflow results are recorded and issued. A system that has been balanced and measured is a different thing from a system that has been switched on.
The project team remains contactable for defects, and the same engineers can carry the installation into a maintenance contract. Halo has been working in Dubai since 1996 and is not difficult to find.
Halo is a contractor rather than a callout service, so our AC maintenance work is scheduled rather than reactive. A planned maintenance contract puts an engineer in front of your equipment on a fixed frequency, records how it is performing, and finds the blocked drain or the fouled coil in March instead of during the first forty-five degree week of the year. Contracts cover single premises or a portfolio of units across Dubai.
Planned preventive maintenance on a fixed frequency — commonly quarterly for offices and retail, monthly for kitchens and high-load areas — so faults are found on a visit rather than on the hottest afternoon of the year.
Filter cleaning and replacement, evaporator and condenser coil cleaning, condensate tray and drain-line clearing, and airflow checks at the diffusers. Blocked drains and dirty coils cause most of the failures we are called to.
Supply and return temperatures, pressures, running current and controls operation are recorded, so a unit that is degrading is visible in the log before it stops working.
Distribution board inspection, thermal checks on terminations, RCD testing and emergency lighting function tests can sit in the same contract as the AC scope rather than under a separate provider.
One office floor, a retail chain across several Dubai malls, or a landlord’s portfolio of units — the contract is written around the asset list and the access each building actually permits.
Where a component does fail, it is diagnosed by engineers who hold the as-built drawings and the commissioning results for that system, rather than by someone seeing it for the first time.

We engaged Halo Interiors for a turnkey renovation project at our property in Dubai Creek Harbour. Halo handled the entire project including design, procurement, permits, and execution of the works. Halo worked to a tight deadline and delivered a stunning design, which they then implemented to a very high standard. The quality of execution was head and shoulders above anything else I have seen in Dubai, with attention to every detail and very thorough quality control. As a client, I also felt that Halo were very honest in our dealings and this really made a difference. The pricing was also competitive and fully transparent. I cannot recommend Halo highly enough.
See full Google reviewI am so thankful Jason and Zishan from Halo for their help to conduct a property inspection and support us in how to handle a renovation project that went terribly wrong. If I could do things over again, I would have consulted with Halo prior to our renovation project and would have asked for their guidance and project management support. There are a lot of shady contractors in Dubai apparently and these guys are the only honest people you can rely on. I would give them 6 stars if I could!
See full Google reviewWe have had the pleasure of working with Halo Interiors on three different projects, and the experience has been nothing short of exceptional. Our clients have praised the quality and service provided, and we have not faced a complaint. Their premium quality joinery speaks for itself. A special mention to Huzefa, the project manager, who expertly handled our most recent renovation. I highly recommend Halo Interiors to anyone seeking top-notch craftsmanship and reliable service.
See full Google reviewWe contracted Halo for our first villa upgrade project in early 2022 and we have been using their services since then. I cannot but help appreciate the extra effort they take to ensure all our requirements are addressed. Extremely professional and reliable. I would recommend them without hesitation!

Check My BuildingMEP is the least visible part of a fit-out and the part most likely to decide whether it works. On most projects it is doing several jobs at once.
Dubai cooling is the largest line on most commercial utility bills. A system sized to a real load, ducted without unnecessary resistance and actually balanced costs materially less to run than one that was guessed at.
Earthing, fire-stopping, damper positions and emergency lighting are what an inspector looks for. They are inexpensive to build correctly and expensive to open a finished ceiling to correct.
Most complaints about a Dubai fit-out arrive in summer and are about temperature. Load calculation, diffuser positions and air balancing are what decide whether the far corner of the floor is usable.
Ceiling void congestion is the most common cause of a fit-out losing weeks. Coordinating duct, pipe, tray and sprinkler on a drawing costs a day; discovering the clash on a scaffold costs a fortnight.
Commissioning data and as-built drawings turn a future fault into a diagnosis rather than an investigation, whoever is holding the spanner.
Labelled boards, accessible valves and dampers, documented routes and a complete O&M file are what make the building maintainable for its whole life, not just until handover.
Approval requirements vary by building, jurisdiction and the nature of the works, and they are sequential — each stage depends on the one before it. Halo identifies the route that applies to your premises before the programme is confirmed. The stages below describe how MEP approvals normally run in Dubai; they are not a substitute for the current published requirements, which the authorities can and do revise.
Dubai towers and communities require a No Objection Certificate from building management before MEP works start, and most maintain a list of contractors permitted to work on site. Access permits, working hours, lift bookings, hot-work permits and insurance certificates are confirmed before mobilisation rather than discovered on the first morning.
Where the works increase the connected load, alter the incoming supply or change the metering arrangement, drawings and calculations are submitted to DEWA and the installation is inspected. A DEWA-approved contractor submits documentation in the format the authority expects, which is the difference between one review cycle and three.
Authority approvals coordinated with interior fit-out
Any change to sprinkler coverage, detection, emergency lighting, exit routes or compartmentation requires amended fire drawings approved before the work is done, not after. Fire dampers where ductwork crosses a compartment line and fire-stopping at every service penetration are inspection items in their own right.
Civil Defence submissions and gypsum works and compartmentation
Electrical test results, pressure test records, air balancing sheets and functional test records close the works out, alongside as-built drawings and O&M manuals. This documentation is what the building, the authority and any future contractor will ask you for, and it is part of the scope rather than an extra.
There are a great many MEP contractors in Dubai and a much smaller number who employ the engineers who will actually do the work. These are the six questions worth asking every one of them — including us.
Many MEP contractors in Dubai win the work and subcontract all of it. You then have a commercial relationship with one company and a technical relationship with another, and neither will own a clash.
Halo’s mechanical, electrical and plumbing teams are in-house, alongside the fit-out, gypsum and joinery teams they have to coordinate with.
Air balancing and electrical testing are the easiest lines to leave out to make a number look competitive, and their absence is invisible until the system underperforms and nobody can prove why.
Testing, balancing and commissioning are included in the scope, and the results are issued with the as-builts and O&M manuals.
These sit on the boundary between the MEP contractor, the fit-out contractor and the building’s fire contractor. When nobody has priced them, they are found at the Civil Defence inspection.
Both are stated explicitly as included or excluded in the itemised scope before the contract is signed.
A quote produced without a site visit assumes spare ways and spare capacity. If the board is full or the supply is short, the variation arrives after you have already committed.
Spare capacity, incoming supply, void depth and drainage positions are confirmed on site before we price, because the landlord drawing is frequently wrong.
A contractor who has to route submissions through a third party adds a fee, a delay and a layer between you and the reviewer’s comments.
Halo prepares and submits the drawings as a licensed contractor and attends the inspections.
An installer who disappears at handover leaves the next engineer to reverse-engineer the system from scratch, usually during a failure.
The installation can be carried straight into a maintenance contract with the engineers who hold its drawings and commissioning data.

Read MoreStraight answers to the questions Dubai clients ask before appointing an MEP and HVAC contractor.
MEP stands for mechanical, electrical and plumbing — the three service disciplines that make a building work. In Dubai the trade licence term is normally electromechanical contracting. On a fit-out that means the air conditioning and ventilation, the electrical distribution, lighting and small power, the water supply and drainage, and the fire and life-safety interfaces the layout affects. Halo delivers all of it in-house and coordinates it with the fit-out, rather than pricing the package and placing it with a subcontractor.
As a planning figure, the MEP package on a standard commercial fit-out generally runs between AED 90 and 180 per square foot, rising to AED 180–350 for high-spec or clinical premises. The three things that move it most are whether the existing distribution board has spare capacity, how far wet areas move from the existing drainage, and how much ceiling void depth you have to route services through. All three are confirmed on site before we price, because the landlord drawing is frequently wrong about all three.
We do. Where the works increase the connected load, alter the incoming supply or change the metering, Halo prepares and submits the drawings and calculations as a licensed contractor and attends the inspection. DEWA connection and capacity-upgrade fees remain payable in your own name and sit outside the contract value.
Yes. A large share of our work is delivering a design someone else produced, as an MEP subcontractor to a main contractor or directly to a client. We work to the issued drawings, produce the shop drawings and coordinated services drawing, and raise clashes formally rather than solving them silently on site — which is what keeps the as-built matching the design.
A wall-mounted split serves one room from one outdoor unit and is the cheapest to install. A ducted split hides the indoor unit in the ceiling void and distributes air through ductwork to several diffusers, which looks better and controls a larger area from one thermostat. A VRF or VRV system runs many indoor units from one outdoor unit with independent control and much better part-load efficiency, and is normally the right answer above roughly four or five zones. The load calculation and the layout decide which one is appropriate — not the price list.
On a typical Dubai commercial fit-out, first fix through commissioning runs six to fifteen weeks depending on floor area and system type, with design and approvals ahead of it. The item most likely to set the critical path is not the installation but the long-lead plant — VRF outdoor units, switchgear and bespoke ductwork — which is why procurement starts as soon as the design is fixed rather than when site works begin.
Yes. We provide scheduled planned preventive maintenance rather than emergency callouts — commonly quarterly for offices and retail and monthly for commercial kitchens and high-load areas. A visit covers filters, coil cleaning, condensate and drain lines, refrigerant and electrical checks and performance logging, with a written report each time. Electrical maintenance can sit in the same contract. Contracts are written around single premises or a portfolio of units across Dubai.
Almost always because the system was installed but never balanced. Air takes the path of least resistance, so diffusers close to the fan coil unit over-deliver and the far end of the run is starved. It can also be a load calculation that ignored solar gain on a glazed elevation, or a partition added later that now blocks a return path. A survey with airflow measurement at each diffuser identifies which of the three it is, and balancing dampers usually resolve it without replacing plant.
If the works change sprinkler coverage, detection, emergency lighting, exit routes or compartmentation, then yes — and the amended fire drawings are approved before the work is carried out, not after. Moving a single wall usually moves a sprinkler head, a detector and an emergency light, so this applies to far more fit-outs than clients expect. Halo prepares the drawings and coordinates the submission.
Yes, and most of our upgrade work is in occupied premises. Works are phased by zone, noisy and hot works are moved into the hours the building permits — many Dubai towers restrict them to evenings and weekends — and services are isolated in planned, notified windows rather than opportunistically. The programme and the rate both reflect the access the building actually allows, which is confirmed with building management before we price.
As-built drawings, electrical test certificates covering insulation resistance, earth loop and RCD testing, pressure test records for pipework, air balancing sheets showing measured flow at each diffuser, functional test records for controls and life-safety interfaces, and O&M manuals with equipment data and maintenance schedules. This is the file the building, the authority and any future contractor will ask you for.
All of them — Business Bay, DIFC, Sheikh Zayed Road, JLT, Downtown, Dubai Marina and JBR, Al Quoz, Dubai Silicon Oasis, Dubai Investments Park, Dubai Production City, Al Barsha and Dubai Hills Estate among them. Each building carries its own NOC process, approved-contractor list, working hours and access rules, which is why those are confirmed for your specific premises rather than assumed from the district.
