Setting up utilities in Dubai involves more than just monthly bills. DEWA requires a refundable security deposit and specific activation fees before your lights even turn on. Based on the 2026 DEWA consumer schedule, here is exactly what you will pay for residential and commercial properties.

Official detail and updates: dewa.gov.ae (check new connection and security deposit sections before you pay).

Quick presets (annual rent calculator): each link opens the same tool with rent and DEWA options already filled. Change any field after load.

Security deposit (residential)

DEWA holds this as a refundable security amount on the account.

Premises Type	Refundable Deposit	Connection Fee (Small Meter)
Apartment	AED 2,000	AED 155
Villa	AED 4,000	AED 155
Commercial Shop	AED 2,000+	AED 155+

Note: Connection fee includes Registration (AED 10), Knowledge Fee (AED 10), and Innovation Fee (AED 10) on top of the AED 125 base charge.

For property owners, DEWA states the security deposit is refunded when the premises is sold (not on a normal tenant move-out flow). Tenants should confirm their own case in the app or with DEWA.

Activation charges (typical new connection)

These are separate from the security deposit. Amounts below are the common small-meter case (direct-connected meters for lower current ratings). Large meters (higher current, often via CT/VT) use a higher connection fee on the same schedule.

Item	AED
Electricity and water connection (small meters)	125
Registration	10
Knowledge fee	10
Innovation fee	10
Total fixed fees on top of connection	30

So a small-meter residential setup is often 125 + 30 = 155 AED in activation-related charges, plus the security deposit (2,000 or 4,000).

Large meters: DEWA lists 300 AED for connecting electricity and water on large meters, plus the same 30 AED registration, knowledge, and innovation block (check the official table for your meter class).

Discounts: UAE nationals who hold a valid “Thukher” (seniors 60+) or “Sanad” (People of Determination) card from the Community Development Authority may receive 50% off activation charges (see DEWA’s conditions).

DEWA Deposit for Commercial Shops & Offices

For businesses, the deposit is not a flat rate like residential. While it often starts at AED 2,000 for small retail shops, it is ultimately calculated based on the load requirements of the premises.

Pro Tip: Always check the previous tenant's bill or the DEWA "Request for Connection" letter to see the specific meter size, as large meters can significantly increase your initial setup cost.

Chiller charges usually sit outside DEWA

Many buildings run district cooling through a separate provider. In those towers, your cooling bill arrives from that provider, not from DEWA, and monthly charges can land between AED 200 and AED 800 depending on unit size and usage habits.

Municipality housing fee adds every month

Hidden Fee Alert: The 5% Housing Tax

Many newcomers forget that Dubai Municipality charges a 5% annual housing fee on your rent. DEWA simply acts as the collector. For a AED 100,000 rental, expect an extra AED 417/month added to your utility bill automatically.

Setting up the account

Finish Ejari first, then apply through the DEWA app or website. Upload documents, pay security deposit plus activation, and activation usually completes within about 24 hours when paperwork is clean.

How the refund works (tenants)

After account closure and final bill settlement, the security deposit is refunded according to DEWA rules. Keep your account number and closure confirmation until the money lands.

Why this matters for budgeting

Utility setup is not a tiny side cost in Dubai. Security deposit + activation + housing fee + cooling can move your first-month cash need by several thousand dirhams.
