A Technical Service License allows individuals and companies to legally provide maintenance, installation, and repair services in Dubai. It suits skilled professionals looking to operate in a regulated, high-demand market while ensuring compliance with local business laws.
A technical services license lets you carry out hands-on maintenance, repair, and installation work in Dubai, such as plumbing, electrical, air conditioning, and finishing. It is a service license, not a trading one.
It is an umbrella, not a single activity. The DET list holds more than 50 technical activities, each with its own code. The codes you pick decide the jobs you can bill and the outside approvals you must clear.
Technical services group into a few clear families. Most firms pick three to five activities from one or two of these, matched to their trade.
The DET license is only the first layer. The activity you choose decides which outside bodies must also sign off before you can legally do the work.
Plumbing, electrical, and general building work usually need a municipality approval to proceed.
Electrical connection and works are cleared through DEWA before they can be carried out.
Fire fighting systems and safety-critical work require Civil Defence sign-off.
Building work needs a municipality grade proving capability for buildings up to about five floors.
These activities trigger extra approvals, adding roughly 5 to 10 days and AED 2,000 to 5,000.
Doing work without a required approval risks fines that can reach AED 50,000, so plan them early.
For technical services, the choice usually favours the mainland, and the reason is where you can work. A mainland license lets you serve any site across Dubai and bid on government contracts. A free zone license is cheaper and faster, but limits where you can operate.
Most maintenance and installation firms go mainland, because the work is on client sites all over the city and a lot of it is public sector. A free zone suits a technical business that serves clients inside the zone or works on a support or advisory basis rather than on site.
| Factor | Mainland (DET) | Free Zone |
|---|---|---|
| Work across Dubai | Yes, any site | Restricted |
| Govt contracts | Can bid | Cannot bid |
| Setup cost | Higher | Lower |
| Local Service Agent | Some structures | Not needed |
| Visa quota | Scales with office | Capped by package |
| Best for | On-site work | Zone or support |
Government license fees run roughly AED 12,500 to 16,000. The real year-one total is higher once office, approvals, an LSA, and visas are added, and it differs by route.
Mainland Year One, Realistic
Covers the DET license, Ejari, any Local Service Agent, external approvals, and staff visas for a small technical firm.
All figures are indicative and current to early 2026. Government fees are set by the DET and other authorities and change at their discretion, while approvals and visa costs vary by activity and size. RIZ & MONA Consultancy provides a personalized quote before you commit to any step.
Every stage from activity choice to a live trade license runs in the order the DET sets.
Pick 3 to 5 exact DET codes that match the technical work you will do.
Decide mainland or free zone, then pick your legal form and any LSA.
Reserve a compliant trade name and secure DET initial approval.
Lease a unit and register the tenancy contract through Ejari.
Get municipality, DEWA, or Civil Defence sign-off where your activity needs it.
Settle fees, get the license, then process your establishment card and visas.
Mainland Licensing
Working Days
A free zone license is quicker, at 3 to 7 working days. Any external approval adds 5 to 15 days, depending on the activity and body.
Warning: The wrong activity code is the most common cause of delay, and it can also block your bank account and visas later. Confirming the exact codes at the start saves costly amendments.
A mainland technical services license takes 7 to 14 working days with complete documents. External approvals can extend that, so activities that need sign-off are the ones to start early.
A technical services firm needs a corporate account to invoice clients, pay technicians, and run maintenance contracts. Banks review the license, activity, and cash flow. RIZ & MONA Consultancy prepares your file for that review.
