Frequently Asked Questions
What does the Building Mechanical Engineering Services licence (activity code 7110.66) cover
Activity code 7110.66 covers the design, consultancy, and specification of building mechanical systems. This includes HVAC design, plumbing and drainage systems, fire suppression and fire protection engineering, mechanical plant and equipment specification, and building services engineering across residential, commercial, industrial, and infrastructure projects.
It is classified as a professional services licence, not a contracting licence. Physical installation or on-site contracting work requires a separate mechanical contracting licence. Firms offering both services typically hold two licences or route contracting work through a related entity.
What is the difference between a mainland and a free zone licence for this activity
A mainland licence issued by the Dubai Department of Economy and Tourism (DET) allows direct engagement with UAE government tenders, semi-government bodies, and local private clients without restriction. It is the preferred route for firms targeting public-sector projects.
A free zone licence — such as one issued through Meydan Free Zone — suits firms operating internationally, working through B2B contracts, or requiring 100% foreign ownership from the outset. Client-facing work within the UAE may require a mainland branch or a formal service agreement arrangement depending on the nature of the engagement.
Which regulatory body oversees Building Mechanical Engineering Services licences in Dubai
The Dubai Municipality Engineering Affairs Department is the primary regulatory body governing engineering activity approvals and classifications in Dubai. Firms operating under activity code 7110.66 should consult DM's engineering consultancy registration requirements at dm.gov.ae.
Key obligations include registration with Dubai Municipality's Engineering Consultancy Classification system before tendering on regulated projects, and compliance with classification tiers that determine the scale and type of projects the firm may undertake.
What professional qualifications are required to obtain this licence
Firms must appoint a qualified Technical Responsible Manager (TRM). This individual must hold a UAE-recognised engineering degree and meet minimum experience thresholds set by Dubai Municipality.
The responsible engineer is also typically required to hold Society of Engineers UAE (SOE) membership or an equivalent professional registration. Further details on SOE membership requirements are available at soe.ae.
Can a foreign national own 100% of a Building Mechanical Engineering Services company in Dubai
Yes, but the route depends on the chosen jurisdiction. Free zone structures permit 100% foreign ownership with no local sponsor requirement, making them a straightforward starting point for non-UAE nationals.
On the mainland, the legal form matters. A Civil Company structure allows professional engineers to hold full ownership, while an LLC structure traditionally requires a UAE national shareholder holding 51%. In practice, nominee arrangements and profit-sharing agreements are common. A local service agent structure applies to sole establishments and certain professional firms under specific conditions.
How long does it take to set up a Building Mechanical Engineering Services licence in Dubai
Setup timelines vary by jurisdiction. A free zone licence typically takes 2–5 weeks from application to operational status, as free zone authorities manage most of the process internally.
A mainland licence generally takes 4–8 weeks, reflecting the additional steps involved with DET approvals, Dubai Municipality engineering classification registration, and the appointment and verification of a Technical Responsible Manager.
Is there a minimum share capital requirement for this licence
Share capital requirements vary by jurisdiction. Most free zones do not impose a fixed minimum share capital for a professional services licence of this type, making initial setup costs more flexible for smaller firms and startups.
On the mainland, share capital requirements depend on the chosen legal structure. It is advisable to confirm current requirements directly with the relevant authority — the DET for mainland entities or the specific free zone authority — as thresholds can change and may differ between entity types.
Does this licence allow a firm to physically install mechanical systems on construction sites
No. Activity code 7110.66 is a professional consultancy and design licence. It authorises firms to design, specify, and advise on building mechanical systems, but does not permit on-site physical installation or contracting work.
For firms wishing to carry out both design and installation, a separate mechanical contracting licence is required. Many firms in this sector either hold both licences or structure their contracting operations through a related but separately licensed entity to remain compliant with Dubai's regulatory framework.
Building Mechanical Engineering Services License in Dubai
The UAE construction sector is projected to pass USD 136 billion by 2028, and every building inside that number needs its HVAC, plumbing and fire protection designed by somebody licensed to do it. Activity code 7110.66 is that license.
The line defining it is design against installation. You specify and advise. You do not install. Anyone wanting to do both holds two licenses or routes the installation through a related entity. This guide covers what the license allows, who commissions the work, how mainland and free zone compare, the setup steps, and the professional registrations that gate your ability to tender.
Key Stats at a Glance
What This License Covers
Code 7110.66 sits under ISIC Division 71. It is a professional services license covering the design, consultancy and specification of building mechanical systems.
What falls inside it:
- HVAC design, covering heating, ventilation and air conditioning
- Plumbing and drainage systems
- Fire suppression and fire protection engineering
- Mechanical plant and machinery specification
- Building services engineering across residential, commercial, industrial and infrastructure projects
What falls outside it is the important part. This license does not permit physical installation on site. That needs a separate mechanical contractor license. Firms wanting to design and install either hold both licenses or route the installation work through a related but separately licensed entity, which is standard practice in this sector rather than a workaround.
Who Your Clients Will Be
Demand concentrates in four segments, and they are not equally attractive:
- Data centres, where cooling and mechanical plant design is high-value and technically demanding
- Healthcare facilities, with complex mechanical needs and strict compliance
- Hospitality, meaning large hotels and resorts with bespoke HVAC and building services
- Residential developments, volume-driven with repeat work from master developers
Data centres deserve the attention. The technical difficulty is what protects the fee, and fewer firms can do it well.
There is also a route to early revenue that does not depend on winning tenders. Working as a sub-contractor to tier-one firms such as Alec or Khansaheb gets you billing without carrying the overhead of direct tender management, which suits a firm in its first year.
Mainland or Free Zone
Get this decision right before anything else, because it drives your ownership structure, your client access and which approval bodies you deal with.
A mainland license from the Department of Economy and Tourism gives direct engagement with UAE government tenders, semi-government bodies and local private clients with no restriction. If public-sector projects are the target, that is the route, and the legal form matters: a Civil Company lets professional engineers hold full ownership, while an LLC traditionally involves a UAE national shareholder at 51%. A local service agent structure applies to sole establishments and certain professional firms.
Meydan Free Zone gives 100% foreign ownership with no local sponsor, faster setup, and packages built for lean professional teams without large office commitments. It suits a firm working internationally or through business-to-business contracts. Let your clients decide it, not the price.

Step by Step Setup Guide
- Step 1, decide your jurisdiction: Mainland through DET, or a free zone. This drives ownership, client access and approval bodies, so settle it before anything else.
- Step 2, book your trade name: Through the Invest in Dubai portal for mainland, or your free zone authority. Names must follow UAE naming rules, so no religious references, nothing offensive, and nothing already in use.
- Step 3, submit initial approval: File activity code 7110.66 with your qualified engineer's credentials, passport copies, and a No Objection Certificate from a current employer if that engineer already works in the UAE.
- Step 4, secure external approvals: Engineering activity approval comes from Dubai Municipality Engineering Affairs. Depending on your scope, fire suppression for instance, you may also need approvals from Civil Defence or DEWA.
- Step 5, finalise your legal structure: Execute the Memorandum of Association for an LLC, or Articles of Association for a free zone entity or Civil Company, and pay the license fees.
- Step 6, complete post-license registrations: Collect the license, register the firm with the Society of Engineers UAE, and apply for the Engineer Establishment Card from Dubai Municipality. That card is what lets you make project submissions and get Municipality approvals.
- Step 7, open a corporate bank account: Banks want a valid trade license, an Ejari-registered tenancy and full shareholder documents. Allow two to four weeks, and longer where the firm has no local revenue history.
Sequence matters here more than in most activities: jurisdiction first, qualified engineer second, Dubai Municipality registration third. Running those out of order is the most common cause of delay and extra cost.
Compliance and What You Need in Place
Dubai Municipality registration tiers
Register with Dubai Municipality's Engineering Consultancy Classification system before you tender on regulated projects. The tiers within it decide the scale and type of projects your firm can take on, so your tier is effectively your ceiling.
Technical Responsible Manager
You have to appoint a qualified Technical Responsible Manager holding a UAE-recognised engineering degree and meeting Dubai Municipality's minimum experience thresholds. The TRM also needs a valid UAE residency visa tied to the firm, so process that visa alongside the Municipality registration rather than after it.
Professional membership
The responsible engineer typically needs Society of Engineers UAE membership or an equivalent professional registration.
The installation boundary
Keep design and installation separate. This license covers consultancy and design only, and taking on site installation under it puts you outside your permitted scope.
Visas and office
Your visa quota follows your office space category and your jurisdiction. Free zone packages usually bundle allocations, which suits a small professional team.
Market Opportunity
The headline number is the pipeline. UAE construction is projected to exceed USD 136 billion by 2028, driven by government infrastructure programmes, Expo legacy projects and steady private development. For mechanical and building services firms that is a multi-year run of work rather than a spike.
The Municipality registration creates the real commercial gate. Firms registered on that system can approach government and semi-government tenders directly, and the channel opens only once your establishment card and tier are in place. Everything before that is private-sector work.
That sequencing suggests an obvious strategy. Start with private developers and sub-contractor work to build revenue and a track record, complete your Municipality registration alongside it, then move into tendering once the firm can carry it.
Conclusion
This is a well-defined regulated professional license with a clear setup path and a construction market behind it that is not slowing.
The decisions are jurisdiction first, then your qualified engineer, then Dubai Municipality registration. Skipping steps or reordering them is what costs firms time and money.
And keep the design boundary visible. This license is for specifying mechanical systems, not installing them, and any firm wanting to do both needs a second license rather than a generous reading of this one.
