DEWA (Dubai Electricity and Water Authority) is the government utility responsible for supplying electricity and water across Dubai. Every household and business connected to the grid receives a monthly DEWA bill, which combines usage-based charges with several flat fees that apply regardless of consumption.
What's Actually on a DEWA Bill
A DEWA bill isn't just electricity and water usage — it typically includes a housing fee (a flat percentage-based charge tied to your annual rent, split monthly), a fuel surcharge that moves with global energy prices, and the usage-based electricity and water charges themselves, billed in increasing price slabs as consumption rises.
Why the Housing Fee Dominates for Small Homes
Because the housing fee is flat and tied to rent rather than usage, a small studio can end up with a bill where the fixed charges make up a large share of the total, even with modest electricity and water consumption — which is why two very different usage patterns can produce surprisingly similar bills.
Setting Up a New DEWA Account
Moving into a new place requires activating a DEWA account, usually alongside your Ejari tenancy registration, with a refundable security deposit that varies by property type.

Frequently Asked Questions
Is DEWA only for Dubai?
Yes — other emirates have their own utility authorities (like ADDC/AADC in Abu Dhabi and SEWA in Sharjah), each with different rate structures.
Why is my DEWA bill high even though I barely used the AC?
The flat housing fee and fuel surcharge apply regardless of usage, so a bill can stay relatively high even in low-consumption months.
Is the DEWA security deposit refundable?
Yes — it's typically refunded when you close the account, minus any outstanding charges.
Does DEWA billing change seasonally?
Usage-based charges naturally rise in summer with higher air conditioning use, while the flat fees stay the same year-round.
Can I estimate my DEWA bill before moving in?
Yes — using your expected rent (for the housing fee) and typical usage patterns for a property of similar size.
