"I barely used the AC. Why is my bill AED 600?" I hear some version of that from almost every first time landlord or tenant in Dubai. The answer is usually that a Dubai utility bill isn't just electricity and water. It carries a municipality housing fee that has nothing to do with how much power you use, and in many buildings there's a separate chiller bill that charges you even when the AC is off. Once you understand the three pieces, the numbers stop being a surprise.
Piece one: DEWA electricity and water
DEWA (Dubai Electricity and Water Authority) bills on slabs. The more you use in a month, the higher the rate for each extra unit. These are DEWA's residential rates as published on its slab tariff page in October 2026:
On top of that sits a fuel surcharge, which DEWA adjusts with fuel costs. In recent months DEWA has listed AED 0.06 per kWh on electricity and AED 1.10 per cubic metre on water. Add small monthly meter charges and 5% VAT.
Most apartments never leave the first electricity slab. A studio or one bedroom in a building with district cooling might use a few hundred kWh a month. A villa running its own AC units in July is a different story, and that's where the higher slabs start to bite.
Piece two: the housing fee
This is the line that confuses people most. Dubai Municipality charges expatriate residents a housing fee, collected through the DEWA bill in 12 monthly instalments. It has nothing to do with consumption.
For tenants, it's 5% of the annual rent registered in Ejari. The maths is simple:
For owners living in their own home, the fee is assessed on a rental value rather than an actual lease. Guides from major portals describe it as 5% of the RERA average rental value for the unit. If you think yours is wrong, Dubai Municipality has an adjustment service. UAE nationals are exempt.
Per DEWA's VAT guidance, the housing fee isn't subject to VAT. And if your rent drops at renewal, update it with the Municipality, otherwise you'll keep paying the fee on the old figure.
So when a tenant tells me their bill is "too high", the first thing I check is whether they've mistaken the housing fee for electricity. More often than not, that's it.
Piece three: chiller (district cooling)
Many Dubai apartment buildings don't make their own cold air. They buy it from a district cooling provider like Empower or Emicool, through chilled water piped into the building. If your building works this way, your AC isn't on your DEWA bill at all. It's a separate bill, with its own account and deposit.
And here's the part that catches people out. District cooling usually has two charges:
- A demand (capacity) charge: a fixed amount based on your unit's contracted cooling capacity, measured in refrigeration tons (RT). Empower lists AED 750 per RT per year, billed monthly in advance. You pay it whether or not you switch the AC on.
- A consumption charge: based on how much cooling you actually use, measured in RT hours. Rates vary by provider, so check your provider's current tariff.
Say your apartment has a contracted capacity of 2 RT. The demand charge alone is AED 1,500 a year, about AED 125 a month, before consumption, meter fees and VAT. That's why someone who travels all summer still gets a chiller bill. Empower also notes that demand and meter maintenance charges continue during a voluntary temporary disconnection.
Some buildings are marketed as "chiller free". That usually means the landlord or service charges cover cooling, or the building uses its own system with power on DEWA. Ask exactly what it means before you assume your bills will be lower.
A worked month, start to finish
Let's take a one bedroom apartment rented at AED 60,000 a year, in a district cooled building, using 600 kWh of electricity and 8 cubic metres of water in a month. These are illustrative numbers, not a quote:
Look at that DEWA total again. Almost half of it is the housing fee. Actual electricity is under AED 140.
Move in costs: the deposits
When you open a DEWA account for a new home, expect:
- Security deposit: AED 2,000 for an apartment, AED 4,000 for a villa, refundable
- Connection and service fees: for a small meter, about AED 155 in total
So an apartment needs roughly AED 2,155 upfront before any bill arrives. A district cooling account usually needs its own deposit too. Empower's has been reported at AED 2,000 for a flat, but confirm the current amount for your building. If you're an owner, note that DEWA's move in guidance says owner deposits are refunded when the property is sold.
If you're buying to rent out
This matters more than most investors realise. Tenants compare total monthly cost, not just rent. A unit with a high chiller demand charge can be harder to rent than a similar one in a building where cooling is covered. Before you buy, especially off plan, ask:
- Is cooling on DEWA, district cooling, or included in service charges?
- If district cooling, who's the provider, and what's the contracted RT for this unit?
- What's the deposit, and are there connection or meter fees?
- Who pays chiller charges while the unit is empty between tenants? (Usually you.)
Put the answers alongside your service charge estimate. Our guide to Dubai service charges covers that side, and our rental yield guide shows how running costs eat into returns. If you're near handover, add utility checks to your snagging list too: meters working, AC actually cooling, no leaks.
Honest take
Dubai utilities aren't expensive for most apartments. What's expensive is not knowing what's on the bill. Check the housing fee matches your real rent, find out how your building is cooled before you sign anything, and budget the deposits from day one. If you're a buyer from abroad weighing the total cost of a unit, our guide to what a Dubai apartment really costs puts these running costs next to the purchase fees. Tariffs change, so confirm current rates on DEWA's and your cooling provider's websites before you budget. If you want help checking a specific building, our Dubai team can pull the details for you.
