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.

Calculate NowWhat This Licence Covers
Activity code 7110.66 sits under ISIC Division 71 — engineering activities and related technical consultancy. It is a professional services licence, not a contracting licence, and that distinction matters operationally.
The scope covers the design, consultancy, and specification of building mechanical systems, including:
- HVAC (heating, ventilation, and air conditioning) design
- Plumbing and drainage systems
- Fire suppression and fire protection engineering
- Mechanical plant and equipment specification
- Building services engineering across residential, commercial, industrial, and infrastructure projects
This licence covers consultancy and design work. Physical installation or contracting on-site requires a separate mechanical contracting licence. Firms offering both services typically hold two licences or structure the contracting work through a related entity.
Mainland vs Free Zone Scope
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.
A free zone licence — such as one issued through Meydan Free Zone — is well suited to firms operating internationally, working through B2B contracts, or structuring for 100% foreign ownership from day one. Client-facing work within the UAE may require a mainland branch or a formal service agreement arrangement depending on the nature of the engagement.

Get Your LicenseRegulatory and Professional Requirements
Dubai Municipality's Engineering Affairs Department governs engineering activity approvals and classifications in Dubai. Firms intending to operate under activity code 7110.66 should familiarise themselves with DM's engineering consultancy registration requirements at dm.gov.ae.
Key regulatory obligations include:
- Registration with Dubai Municipality's Engineering Consultancy Classification system before tendering on regulated projects
- Appointment of a qualified Technical Responsible Manager (TRM) — a UAE-recognised engineering degree and minimum experience thresholds are required
- Society of Engineers UAE (SOE) membership or equivalent professional registration for the responsible engineer — details at soe.ae
- Compliance with Dubai's engineering consultancy classification tiers, which determine the scale and type of projects the firm can undertake
Professional Qualifications and Local Sponsorship
On the mainland, the legal form determines the ownership structure. A Civil Company structure allows professional engineers to hold full ownership, while an LLC requires a UAE national shareholder holding 51% — though in practice, nominee arrangements and profit-sharing agreements are common. A local service agent structure applies to sole establishments and professional firms under certain conditions.
Free zone structures allow 100% foreign ownership with no local sponsor requirement. For firms where the founders are not UAE nationals, this is often the more straightforward starting point.

The setup sequence below applies to both mainland and free zone routes. The steps are the same; the timelines and approval bodies differ.
- Step 1 — Define jurisdiction: Decide between mainland (DET) or free zone (e.g. Meydan Free Zone). This decision drives ownership structure, client access, and the approval bodies involved. Get this right before anything else.
- Step 2 — Reserve trade name: Submit via the DET's Invest in Dubai portal at invest.dubai.gov.ae for mainland, or through the relevant free zone authority. Names must comply with UAE naming conventions — no religious references, no offensive terms, no names already in use.
- Step 3 — Initial approval application: Submit activity code 7110.66 with the qualified engineer's credentials, passport copies, and NOC from current employer if the engineer is already employed in the UAE.
- Step 4 — External approvals: Secure engineering activity approval from Dubai Municipality Engineering Affairs. Depending on the specific service scope — for example, fire suppression systems — approvals from Civil Defence or DEWA may also be required.
- Step 5 — Finalise legal structure: Execute the Memorandum of Association (LLC) or Articles of Association (free zone entity or Civil Company), and pay the relevant licence fees to the issuing authority.
- Step 6 — Post-licence registrations: Obtain the licence certificate, register the firm with SOE UAE, and apply for the Engineer Establishment Card from Dubai Municipality — this card is required for project submissions and DM approvals.
- Step 7 — Corporate bank account: UAE banks require a valid trade licence, tenancy contract (Ejari-registered), and full shareholder documentation. Allow two to four weeks for account opening; some banks take longer for professional services firms without local revenue history.
Estimated Costs and Timelines
- Free zone licence fees typically range from AED 12,000 to AED 25,000 annually, depending on the package and visa allocation included
- Mainland professional licence costs vary; DET fees, DM engineering registration, and name reservation collectively add AED 8,000 to AED 20,000 or more, before office costs
- Full setup including external approvals: 2–5 weeks for a free zone; 4–8 weeks for mainland with DM engineering registration factored in
Commercial Opportunity and Market Position
The UAE construction sector is projected to exceed USD 136 billion by 2028, driven by government infrastructure programmes, Expo legacy projects, and sustained private development activity. For MEP and building services firms, this represents a multi-year pipeline with no near-term contraction in sight.
Demand is concentrated in specific segments:
- Data centres — cooling and mechanical plant design is a high-value, technically demanding niche
- Healthcare facilities — complex mechanical requirements with strict regulatory compliance
- Hospitality — large-scale hotels and resorts with bespoke HVAC and building services
- Residential developments — volume-driven, with repeat engagement from master developers
Firms registered with DM's engineering classification system can access government and semi-government tenders directly — a significant revenue channel that unlocks once the establishment card and classification are in place. For firms in early-stage operations, subcontracting relationships with tier-one contractors such as Alec, Khansaheb, and similar firms represent a practical route to initial revenue without the overhead of direct tender management.
Visa and Staffing Considerations
The licence entitles the entity to sponsor employment visas. The quota depends on the office space category and the jurisdiction. Free zone packages typically bundle visa allocations — Meydan Free Zone packages are structured to suit lean professional teams without requiring large office commitments.
The Technical Responsible Manager must hold a valid UAE residency visa tied to the firm. Factor this into the setup sequence — the TRM visa should be processed in parallel with the DM engineering registration.
Conclusion
A Building Mechanical Engineering Services licence under activity code 7110.66 is a well-defined, regulated professional licence with a clear setup pathway. The choice between DED mainland — which provides full market access including government tenders — and a free zone structure — which offers ownership simplicity and faster setup — comes down to your client base and commercial priorities.
The regulatory steps are manageable if sequenced correctly: jurisdiction first, qualified engineer second, DM registration third. Skipping steps or running them out of order is the most common cause of delays and additional cost.
Speak to a setup adviser who understands both the DED and free zone routes before committing to a structure — the wrong choice costs time and money to unwind.
