A client last month called us in a mild panic. He'd taken over his friend's JLT flat mid-lease — handshake deal, addendum signed, keys swapped. Three weeks later he came home to a 38-degree apartment because Empower had cut the chiller. The friend had "forgotten" to settle the final reading. Now my client was paying his friend's last month plus reactivation, and he hadn't moved a single box yet.
This happens more than you'd think. Mid-tenancy takeovers (subletting with landlord consent, formal lease assignments, friend-to-friend handovers) are a significant slice of the Dubai rental market. Nobody at the brokerage will walk you through the chiller side. Here's what actually has to happen, in order.
Why the Chiller Account Doesn't Just Follow You
Empower and Emicool both treat the chiller account as bound to a person, not a unit. When the outgoing tenant signed up, they paid a capacity deposit (typically AED 2,000) and the account got tied to their Emirates ID. There's no one-click "transfer" option in either portal. Both providers require the outgoing party to formally close the account, the unit to settle, and the incoming party to register fresh.
What that means practically: if you and the outgoing tenant skip a step, you get a 2-3 working day cooling gap (or worse, a billing dispute that costs both of you weeks of back-and-forth).
The Sequence That Works
Do these in order. Skipping or reversing steps is what causes the disputes.
Step 1 — Tenancy Addendum + Ejari Resubmission
The legal foundation has to land first. Your landlord drafts an addendum to the existing tenancy contract naming you as the new tenant (or as the assignee), both parties sign, and the landlord resubmits to Ejari with the addendum attached. Cost is the standard Ejari fee (around AED 220) plus whatever the landlord charges for the addendum admin (often AED 500-1,000 from the property management office).
Without this, neither Empower nor Emicool will register you. The chiller portal asks for the Ejari certificate as one of the registration documents — and it has to show your name.
Step 2 — Outgoing Tenant Submits a Final-Reading Request
This is where the friend in our story tripped up. The outgoing tenant logs into their Empower or Emicool portal, finds "Settlement Request" or "Account Closure," and submits with the move-out date. The provider issues a final invoice within 2 working days based on the reading on the closure date.
The outgoing tenant has to pay this final bill. Their AED 2,000 capacity deposit gets returned (Empower caps cash refunds at AED 5,000 — anything above is by cheque to the registered Emirates ID name). On a clean closure with no overdue, the deposit refund typically arrives within 30 working days, but I've seen it stretch to 60.
If the outgoing tenant's deposit hasn't been refunded by the time you take over, they'll often try to negotiate it into your payment. Don't agree to that without it being in writing in the addendum. Empower will not transfer their deposit to your account directly.
Step 3 — Wait for the Closure to Post (the Risky Window)
This is the dangerous gap. Once the outgoing tenant submits closure, Empower disconnects the chiller within 1-3 working days. If you haven't registered yet, your unit goes off chiller — meaning ambient heat in summer, which in May or June is a fast climb to 35-40°C indoors.
Two ways to avoid this: (a) coordinate timing so your registration is filed the same day as the closure submission, or (b) ask the outgoing tenant to delay the closure submission until your registration is approved. Most outgoing tenants will agree to (b) if it's spelled out in the addendum.
Step 4 — Register Your New Account
You bring the same documents anyone needs for a first-time chiller setup: tenancy contract, Ejari certificate (showing your name from Step 1), passport with valid visa, Emirates ID. Pay the AED 2,000 capacity deposit and the AED 250-ish activation fee. Empower's typical activation is 1 working day; Emicool can take 2-3 in busy periods (Greens, Discovery Gardens, Motor City handovers).
If you skipped Step 1 and try to use the previous tenant's Ejari, the registration fails. The portal flags the name mismatch.
The Empower vs Emicool Wrinkle
The provider depends entirely on the building, not the area. Empower covers JLT, JBR, Palm Jumeirah, Mirdif, Al Khail Gate, Dubai Silicon Oasis, Business Bay (most of it), and a chunk of Downtown. Emicool covers The Greens, Discovery Gardens, Motor City, Sports City, Dubai Marina (parts), and a few mixed-use developments. Both portals are different — different login URLs, different document upload formats, different escalation paths.
Many tenants moving from a JLT (Empower) unit into a Greens (Emicool) unit don't realize until they try to register that they're now dealing with a totally different provider. If your takeover is between two different chiller providers, you're effectively running two parallel processes — close the old, register with the new.
The basics of chiller-included vs chiller-free buildings matter here too — if your new unit is chiller-free (utility built into the rent), there's no separate account to set up at all and the whole process collapses to Step 1.
The Addendum Language That Saves the Argument
The cleanest addendums I've seen for mid-tenancy takeovers include three specific clauses on the chiller side:
- Closure timing: "Outgoing tenant agrees to submit Empower/Emicool closure on [date], conditional on incoming tenant having submitted activation request by same date."
- Deposit handling: "Outgoing tenant's capacity deposit refund remains property of outgoing tenant; incoming tenant pays own AED 2,000 capacity deposit at activation."
- Final-reading payment: "Outgoing tenant settles final invoice within 7 days of issue. Any unpaid amount post-handover is recoverable from outgoing tenant's security deposit held by landlord."
Get these in writing. When the friend-handshake version goes wrong (and it does, as my JLT client learned), there's no other paper trail.
What If the Outgoing Tenant Won't Cooperate?
Rare but real. If the outgoing tenant has left Dubai or refuses to close out, you have two options. First, escalate through the landlord — many tenancy contracts give the landlord the right to settle utilities and deduct from the outgoing security deposit. Second, file with the Dubai Rental Dispute Centre (RDC) — slow but enforceable.
Empower and Emicool will not let you register a new account on a unit with an unresolved closure. You have to clear the old before you can register the new.
Where the Move Fits
Most clients schedule the actual move 5-7 days after the addendum is signed and Ejari resubmitted. That gives you breathing room for the chiller dance and the DEWA transfer (which has its own sequence — covered in our DEWA transfer guide). Our apartment movers team can hold a slot 10 days out and confirm 48 hours ahead once you've got the utilities locked.
If you're handling a villa takeover instead, the chiller side often doesn't apply (most villas are on standalone DEWA cooling), but the Ejari + landlord NOC sequence is identical. Our villa movers page has the equivalent checklist.

FAQ
Can I take over an Empower account from a previous tenant?
Not directly. Empower binds the account to the tenant's Emirates ID, not the unit. The outgoing tenant has to submit a Settlement Request to close out their account; you then register a fresh account in your name with your Ejari and Emirates ID. The two actions need to be coordinated to avoid a 1-3 day cooling gap. The capacity deposit (AED 2,000) does not transfer between tenants.
Do I need a new Ejari to transfer Empower?
You need an Ejari that shows your name as the registered tenant. If the existing Ejari is in the outgoing tenant's name, your landlord has to draft an addendum, both parties sign, and the landlord resubmits to Ejari. Empower's portal will reject your registration if the Ejari name doesn't match your Emirates ID. Plan 3-5 working days for the Ejari resubmission to clear before you start the chiller registration.
Who pays the outstanding chiller bill in a mid-tenancy transfer?
The outgoing tenant. The chiller account stays in their name until they file a Settlement Request and pay the final invoice. Both providers will refuse to register you until the previous account is fully cleared. Best practice: spell this out in the tenancy addendum, with a clause that the landlord can deduct any unpaid chiller balance from the outgoing tenant's security deposit if needed.
Does Emicool require an addendum to the tenancy contract?
Emicool requires the same registration documents as a new tenant: tenancy contract, Ejari, passport with valid visa, Emirates ID. Like Empower, Emicool binds the account to your Emirates ID. The addendum-and-resubmitted-Ejari sequence is what gets your name on the documents Emicool will accept. Activation typically takes 2-3 working days at Emicool, slightly longer than Empower in busy periods.
