A practical guide to connecting electricity and water in Abu Dhabi city: which utility supplies your home, the documents you need, how to open the account through TAMM, the refundable deposit to budget for, and how long the connection takes.
An Abu Dhabi city electricity and water account is set up through the TAMM government services platform, and the two things you must have first are a registered Tawtheeq tenancy contract and your Emirates ID. The utility is the Abu Dhabi Distribution Company (ADDC), and you pay a refundable security deposit of roughly AED 1,000 for an apartment (indicative, confirm on TAMM or ADDC). There is generally no separate connection charge, and the supply is normally switched on within one to two working days.
This guide explains who supplies your utilities depending on where in the emirate you live, the exact documents ADDC asks for, the step by step process through TAMM using UAE PASS, the deposit amounts by property type, and how ADDC compares with Dubai’s DEWA. It also covers the important quirk that many Abu Dhabi city tenants never file a connection request at all, because Tawtheeq triggers the account automatically.
Who Supplies Your Electricity and Water in Abu Dhabi
The emirate of Abu Dhabi is split between two distribution companies, and knowing which one serves your address decides where you apply. Abu Dhabi city and the surrounding region, including most of the island, the mainland suburbs, and the Western Region, are served by the Abu Dhabi Distribution Company (ADDC). Al Ain and its surrounding region are served by a separate utility, the Al Ain Distribution Company (AADC). Both companies now sit under TAQA Distribution, but they remain distinct accounts with their own service areas, so an Al Ain property is connected through AADC, not ADDC.
For customers, the practical difference is small because both utilities are reached through the same TAMM platform. When you start a new connection request you select ADDC or AADC based on the property location, and TAMM routes the application to the right company. The rest of this guide focuses on ADDC and Abu Dhabi city, which is where most expats and new tenants set up, but the documents and the deposit logic are broadly the same for AADC in Al Ain.
Documents You Need to Open an ADDC Account
ADDC connects a residential account against a specific person and a specific registered tenancy, so the paperwork ties your identity to the property. Gather these before you start, because the application will not complete without a registered Tawtheeq contract in particular.
- Emirates ID of the account holder, both sides, matching the person named on the tenancy.
- A registered Tawtheeq tenancy contract, attested through Abu Dhabi Municipality, which is the mandatory prerequisite for any Abu Dhabi city connection.
- Passport with a valid UAE residence visa page for the account holder.
- If you are moving within Abu Dhabi, the closure or clearance letter for your previous ADDC account, so the old deposit can be settled and the new one opened.
The Tawtheeq requirement is the point that trips people up. You cannot connect ADDC without a registered contract, so if your landlord has not yet registered the tenancy through Tawtheeq, that has to happen first. In fact, ADDC states that once a tenancy is registered with Tawtheeq, the water and electricity account is set up for you automatically, so many Abu Dhabi city tenants never file a separate connection request at all. A standalone move-in application is mainly needed for property owners or units outside standard Tawtheeq coverage.
How to Set Up an ADDC Account Through TAMM
The standard route is online through TAMM using UAE PASS, the national digital identity. If you prefer to apply in person, ADDC and TAMM customer care centers handle the same request over the counter with your original documents. The online steps are as follows.
Step 1: Gather Your Documents and Log In With UAE PASS
Have your Emirates ID, registered Tawtheeq contract, and passport visa page ready as digital copies. Log in to the TAMM platform with your UAE PASS credentials. If you do not yet have UAE PASS, you can register it with your Emirates ID before starting, which also makes every other Abu Dhabi government service easier to access.
Step 2: Submit the New Connection Request
Open the housing and utilities services, choose the ADDC new connection or move-in service, and select ADDC for an Abu Dhabi city property. Enter the premises details from your Tawtheeq contract and attach your Emirates ID and the tenancy contract. TAMM validates the premises against the registered tenancy, which is why the contract has to be registered first.
Step 3: Pay the Refundable Deposit
Pay the security deposit online through TAMM to activate the request. The deposit is refundable and is returned when you close the account, minus any final unpaid consumption. There is generally no separate one-off connection fee on top of the deposit for a standard residential move-in.
Step 4: Connection Within One to Two Working Days
Once the request is approved and the deposit is paid, ADDC activates the supply, typically within one to two working days. Where the meter is already energized, as in most occupied city apartments, the account simply transfers into your name and there is no physical visit. If you need supply on a specific date, you can usually schedule it through TAMM when you file the request.
ADDC Security Deposit by Property Type
ADDC charges a refundable security deposit that scales with the property type and electrical load, held against the account and returned on closure. ADDC and TAMM do not publish a fixed public deposit schedule, so treat the figures below as indicative planning numbers and confirm the exact amount on TAMM or ADDC at the point of application, because it depends on whether the unit is single-phase or three-phase.
| Property Type | Indicative Refundable Deposit | Notes |
|---|---|---|
| Apartment or studio (single-phase) | Around AED 1,000 | Most common for city tenants. Confirm on TAMM or ADDC. |
| Villa or townhouse (three-phase) | Around AED 2,500 | Higher load draws a higher deposit. Indicative only. |
| Commercial premises | AED 2,000 and above | Varies with load and activity. Confirm on TAMM or ADDC. |
The deposit is fully refundable. When you close the account through TAMM at the end of your tenancy, ADDC settles your final bill against the deposit and refunds the balance. Keep the account holder’s bank details and Emirates ID handy for the refund, and file the closure before you hand back the keys so the final reading is taken on time. Note that these deposit figures are indicative and reported to vary; the definitive amount is the one shown in your TAMM application.
ADDC Versus Dubai’s DEWA
If you have moved from Dubai, the mechanics are similar but the utility, the portal, and the deposit differ. Dubai is served by the Dubai Electricity and Water Authority (DEWA) and set up through the DEWA app or website, whereas Abu Dhabi runs through ADDC and TAMM. Dubai does not use a Tawtheeq equivalent for the connection itself, though Ejari registration plays a parallel role. The table sets out the headline differences.
| Item | Abu Dhabi (ADDC) | Dubai (DEWA) |
|---|---|---|
| Utility | Abu Dhabi Distribution Company | Dubai Electricity and Water Authority |
| Where to apply | TAMM platform, UAE PASS login | DEWA app or website |
| Tenancy prerequisite | Registered Tawtheeq contract | Ejari registration |
| Apartment deposit (refundable) | Around AED 1,000 (indicative) | AED 2,000 |
| Villa deposit (refundable) | Around AED 2,500 (indicative) | AED 4,000 |
DEWA’s residential deposit is a published AED 2,000 for an apartment and AED 4,000 for a villa, and the way Dubai’s DEWA deposit and refund works is a useful benchmark for what to expect on the Abu Dhabi side. Utilities are only one line in your monthly budget, so it is worth reading our breakdown of the cost of living in Abu Dhabi alongside this, and if your building uses centralized cooling, factor in district cooling and chiller fees, which are billed separately from ADDC electricity.
FAQ
How do I set up an ADDC account in Abu Dhabi?
Apply through the TAMM platform using UAE PASS, or in person at an ADDC or TAMM customer care center. You need a registered Tawtheeq tenancy contract and your Emirates ID, you pay a refundable deposit, and the supply is normally connected within one to two working days. In many Abu Dhabi city rentals the account is created automatically once Tawtheeq registers the contract.
Do I need a Tawtheeq contract to connect ADDC?
Yes. A registered Tawtheeq tenancy contract, attested through Abu Dhabi Municipality, is a prerequisite for an Abu Dhabi city connection, and the application will not complete without one. If your landlord has not registered the tenancy yet, that has to be done first. Once it is registered, ADDC often sets up the water and electricity account automatically.
How much is the ADDC security deposit?
Indicatively around AED 1,000 for a single-phase apartment and around AED 2,500 for a three-phase villa, with commercial premises higher. ADDC and TAMM do not publish a fixed public schedule, so confirm the exact figure in your TAMM application. The deposit is refundable when you close the account.
Is the ADDC deposit refundable?
Yes. The security deposit is held against the account and refunded when you close it through TAMM, after ADDC settles any final unpaid consumption. Provide the account holder’s bank details and Emirates ID for the refund, and close the account before handing back the keys so the final meter reading is taken on time.
How long does an ADDC connection take?
Typically one to two working days after the request is approved and the deposit is paid. Where the meter is already energized, as in most occupied city apartments, the account transfers into your name without a site visit. You can usually schedule connection for a specific date through TAMM when you file the request.
What documents do I need for an ADDC connection?
Your Emirates ID (both sides), a registered Tawtheeq tenancy contract, and your passport with a valid UAE residence visa page. If you are moving within Abu Dhabi, add the closure letter from your previous ADDC account. All must name the same account holder as the tenancy.
Is there a separate connection fee on top of the deposit?
Generally no. For a standard residential move-in the main upfront cost is the refundable security deposit, and there is usually no separate one-off connection charge. Any administrative or knowledge-fee amounts, where they apply, are shown in your TAMM application before you pay.
What is the difference between ADDC and AADC?
ADDC, the Abu Dhabi Distribution Company, supplies Abu Dhabi city and the surrounding region, while AADC, the Al Ain Distribution Company, supplies Al Ain and its region. Both sit under TAQA Distribution and are reached through the same TAMM platform, but you select the correct one based on your property location.
Can I set up an ADDC account without visiting an office?
Yes. The full process runs online through TAMM with UAE PASS, from submitting the request and documents to paying the deposit. An in-person visit to an ADDC or TAMM customer care center is optional and mainly useful if you need help with documents or do not have UAE PASS set up.
How do I close my ADDC account and get my deposit back?
File the account closure through TAMM before you vacate, so a final meter reading is taken. ADDC settles your closing bill against the security deposit and refunds the balance to the account holder. Keep your Emirates ID and bank details ready, and do not leave the closure until after you have returned the keys.
