DEWA, district cooling and summer bills in Dubai

Your first Dubai utility bill will probably surprise you, not because power is dear, but because a slice of your rent and a separate cooling company turn up on it.

The short version

DEWA, the Dubai Electricity and Water Authority, supplies your power and water. Opening an account needs a refundable deposit of AED 2,000 for an apartment or AED 4,000 for a villa, plus an activation fee [1].
Your DEWA bill also collects Dubai Municipality's housing fee: 5% of your annual rent, split over 12 monthly bills [1].
Residential electricity is charged in slabs, from 23 fils per kWh for the first 2,000 kWh a month up to 38 fils above 6,000 kWh, plus a fuel surcharge and 5% VAT [2].
Many apartment towers use district cooling. That's a separate account with a provider such as Empower, with its own deposit, a fixed capacity charge and a metered usage charge [1][3].
Summer runs from June to September and can top 50°C [4], so July and August bills are much bigger than January's.

How it differs from bills back home

In Australia you pick an electricity retailer, compare plans and get a quarterly bill. Cooling is just part of your power usage. In Dubai there's one supplier, the price is set, and in many towers cooling is a separate utility altogether.

Thing	Australia	Dubai
Electricity supplier	Choice of retailers	DEWA only
Deposit	Rare, or a small bond	AED 2,000 apartment, AED 4,000 villa [1]
Billing	Usually quarterly	Monthly
Council rates	Paid by the owner	Renters pay a 5% housing fee via DEWA [1]
Air conditioning	Your own split system on your power bill	Often district cooling, billed separately [3]
Peak bills	Winter heating in the south, summer up north	July and August, everywhere

Setting up DEWA when you move in

DEWA connects to your tenancy record, so your Ejari registration has to be done first. Our renting guide covers Ejari, so here's just the utility part.

Get your Ejari number. Once the lease is registered, the premises is linked to you.
Apply for activation. Use the DEWA app or website with your Emirates ID, Ejari and the premises number. Many agents start this for you.
Pay the deposit and activation fee. AED 2,000 for an apartment or AED 4,000 for a villa. The activation charge starts at about AED 130 for smaller connections and can be higher [1].
Check for district cooling. Ask the agent or building management whether the building is on Empower or another provider, and whether chiller charges are included in rent. If not, open that account too [1].
Set up autopay. Late payment can lead to disconnection, which you don't want to fix in August.
Keep the receipts. Deposits come back when you close the account and settle your final bill [1].

Reading the DEWA bill

A typical DEWA bill has several lines. Here's what they are.

Line on the bill	What it is	2026 rate
Electricity	Your consumption, charged in monthly slabs	23 fils/kWh to 2,000 kWh, 28 fils to 4,000, 32 fils to 6,000, 38 fils above [2]
Fuel surcharge	Added to every kWh	6 fils/kWh [2]
Water	Your water use, also in rising tiers	Tiered, rises with use [2]
Sewerage	Based on water use	Varies [2]
Meter service charge	Monthly fixed charge	AED 5 to AED 35, residential [2]
Housing fee	Dubai Municipality fee for tenants	5% of annual rent, in 12 instalments [1]
VAT	On VAT-able parts of the bill	5% [2]

The housing fee

This is the one that confuses Australians. It's a Dubai Municipality charge for tenants, not for DEWA. On an AED 120,000 a year rent, 5% is AED 6,000 a year, or AED 500 added to each monthly bill [1]. Budget for it when you compare rents. A cheaper flat at the same quality saves you twice.

The slabs

The slab system means the more you use in a month, the more each extra unit costs. The jump from 23 to 38 fils is big, and the top slab only kicks in above 6,000 kWh a month, which is mostly villa territory in summer [2]. An apartment on district cooling uses far less DEWA power because the cooling plant sits outside your meter.

District cooling: the chiller bill

Many towers in Dubai Marina, JLT, Downtown, Business Bay and newer communities don't have their own air-conditioning compressors. Chilled water is piped in from a central plant run by a provider such as Empower or Emicool. You pay that provider directly, unless your building is "chiller-free", meaning the landlord covers it [3].

Gulf News set out Empower's pricing in 2024 [3]:

Capacity (demand) charge. AED 750 per refrigeration ton (RT) per year, billed monthly in advance. A unit rated at 6 RT pays AED 4,500 a year in capacity charges whether you run the air con or not.
Consumption charge. Metered in RT-hours, so you pay more in summer.
Deposit and fees. A refundable security deposit of AED 2,000 for a flat or AED 3,000 for a villa, a meter maintenance fee, and an AED 1,000 disconnection fee.

The capacity charge is what catches new tenants. It's fixed, based on your unit's rated load, and it lands on every bill. A two-bedroom on district cooling can have a chiller bill that rivals the DEWA bill in summer.

Before you sign a lease, ask three things: is the building chiller-free or chiller-paid, who's the provider, and what was the unit's chiller bill in August. Get the answer in writing. A chiller-free building at a slightly higher rent can work out cheaper.

Keeping cool without a shock bill

Summer temperatures can exceed 50°C [4], and the air con runs round the clock from about June to September. Some practical habits:

Service the AC before summer. Clean filters and coils, and check the thermostat. A dirty unit works harder and costs more. Check your lease for who pays for maintenance.
Don't freeze the place. Every degree lower costs more. A setting in the mid-twenties is comfortable once the humidity is down.
Use timers and zones. In a villa, cool the rooms you use. There's no need to chill five bedrooms while you're at work.
Block the sun. Blackout curtains or reflective film on west-facing windows make a real difference.
Watch the water heater. In summer the "cold" tap runs warm anyway. Many residents switch off the water heater for the hottest months.
Going home for the Aussie winter? Leave the AC on low with a timer rather than off. Humidity can bring mould into a closed-up flat. Ask your building what it recommends.
Track it in the app. The DEWA app shows your usage over time, so you can spot a faulty unit early.

Villa owners and solar

If you buy a villa, DEWA's Shams Dubai programme lets owners install rooftop solar and offset their bills. It's worth a look on a big summer load, though it's a decision for owners rather than renters.

Moving out

Close your DEWA account through the app when you leave, and your chiller account too. Settle the final bills and the deposits come back [1]. Your landlord may ask for a DEWA clearance before returning your security deposit, so don't leave it until the last day before your flight to Australia.
