#1. Where to Apply: Tamm and the ADDC Portal
All Abu Dhabi government services, including utility disconnection requests, are channelled through Tamm (tamm.abudhabi). Inside Tamm you select 'Permanent Disconnection of Services' under ADDC for Abu Dhabi properties or AADC for Al Ain. The system links automatically to your Emirates ID and any premises registered in your name.
#2. Documents Required by ADDC and AADC
You will need: Title Deed or Mulkiya, Emirates ID copy, the most recent ADDC/AADC bill, a clearance letter from any tenant (or proof of vacant possession), the appointed demolition contractor's trade licence with classification, and a power of attorney if a representative is acting on behalf of the owner. Commercial properties additionally require the trade licence of the previous occupant.
#3. Step-by-Step Disconnection Process
1. Settle all outstanding bills and request refund of the security deposit. 2. Submit the disconnection request via Tamm and pay the service fee (typically AED 100โ200 per meter). 3. ADDC schedules a site visit within 5โ10 working days. 4. Technicians remove meters and isolate cables/pipes. 5. The NOC is uploaded to your Tamm dashboard within 3โ7 working days after the site visit, provided no outstanding issues remain.
For properties on Tabreed or Empower-equivalent district cooling networks in Abu Dhabi, a separate cooling NOC is required.
#4. Fees and Timelines
Total end-to-end timeline is typically 12โ22 working days for a standard villa, longer for villas with multiple meters, commercial premises, or sites with shared utility connections. Disconnection service fees are AED 100โ200 per meter, plus the final bill settlement and any pending fines.
#5. Common Rejection Reasons in Abu Dhabi
Frequent issues include: unpaid balances, mismatched ownership records (especially after inheritance), unclear Title Deed scans, missing tenant clearance, active commercial leases, and shared utility connections with neighbouring properties (common in older Mussafah and Mohammed Bin Zayed City sites). Resolving these before submitting saves weeks of delay.
