DEWA Bill Calculator
Estimate your Dubai electricity and water bill — slab by slab — and find out why the housing fee is often the biggest line on it.
Advanced — fuel surcharge & other charges
Estimate only, based on DEWA's published 2026 residential slab tariffs. The fuel surcharge changes month to month, and meter, sewerage and municipal charges vary by property and meter type — take those from your actual bill for a precise figure. VAT is applied at 5% to consumption and meter charges; the housing fee, sewerage and municipality fees are VAT-exempt.
The housing fee is not a DEWA charge
This is the line that confuses almost everyone. The housing fee is a Dubai Municipality charge equal to 5% of your annual rent, divided by twelve. DEWA merely collects it. It has nothing to do with how much electricity or water you use.
On an AED 100,000 rent that is about AED 417 every single month, whether you are at home or abroad, whether you run the AC or not. For a small flat in winter it can easily be larger than the electricity charge itself — which is why people who cut their usage are often baffled that the bill barely moves.
It is also exempt from VAT, so it does not attract the 5% that consumption does.
Why summer hurts twice
Air conditioning is 60–70% of household electricity in Dubai, so consumption alone can double or triple in August. But the tariff is progressive, so those extra units are also charged at a higher rate:
| Monthly consumption | Rate for units in that band |
|---|---|
| First 2,000 kWh | 23 fils / kWh |
| 2,001 – 4,000 kWh | 28 fils / kWh |
| 4,001 – 6,000 kWh | 32 fils / kWh |
| Above 6,000 kWh | 38 fils / kWh |
It is progressive, not a flat rate. If you use 3,500 kWh, you pay 23 fils on the first 2,000 and 28 fils only on the remaining 1,500 — not 28 fils on all of it. That is the most common mistake people make when checking their own bill.
The practical consequence: the last units you burn in a hot month are the most expensive ones you will pay for all year.
What actually reduces the bill
- The thermostat is the whole game. Every degree lower raises consumption by roughly 5%. DEWA recommends 24°C.
- Close the curtains during the day — direct sun makes the AC fight the building.
- Service the AC. A clogged filter burns money quietly, every hour.
- Fix drips. A steady leak can waste hundreds of gallons a month.
- Accept what you cannot change. No amount of saving touches the housing fee — it is tied to your rent, not your meter.
Frequently Asked Questions
Why is my DEWA bill so high in summer?
Two things stack up. Air conditioning is roughly 60 to 70% of household electricity in Dubai, so consumption alone can double or triple between winter and August. On top of that, the electricity tariff is progressive: the extra units push you into higher slabs, so you pay 28, 32 or even 38 fils per kWh for them instead of 23. A flat that costs AED 400 in January can easily reach AED 1,000 or more in summer, and a large villa can pass AED 3,000.
What is the housing fee on my DEWA bill?
It is a Dubai Municipality charge equal to 5% of your annual rent, divided into twelve monthly instalments, which DEWA simply collects on the Municipality behalf. It has nothing to do with how much electricity or water you use. On a rent of AED 100,000 that is about AED 417 every month, which for a small flat can be more than the electricity itself. It is also exempt from VAT.
Does my DEWA bill really charge higher rates as I use more?
Yes, and it is applied progressively, not as a flat rate on the whole amount. If you use 3,500 kWh, you pay 23 fils on the first 2,000 and 28 fils only on the remaining 1,500. A common mistake is to multiply every unit by the top rate you reached, which badly overstates the bill. The practical effect is that the last units you use in a hot month are the most expensive ones.
What is the fuel surcharge?
It is a per-unit charge that reflects global fuel prices, applied to both electricity and water, and DEWA revises it periodically. That is why your bill can move slightly from month to month even when your usage does not change. Because it changes, this calculator lets you edit it — take the current figure from your latest bill or the DEWA slab tariff page for the most accurate estimate.
Do I pay the housing fee if I own my home?
Owner-occupiers are generally still charged, with the fee based on a RERA-assessed rental value rather than an Ejari contract, while UAE nationals living in a home they own are exempt. Practice does vary, so check what actually appears on your own bill. In the calculator you can simply leave the rent field empty or untick the housing fee to see the utilities on their own.
How can I actually cut my DEWA bill?
Air conditioning is where the money goes, so the thermostat is the biggest lever: every degree lower increases consumption by roughly 5%, and 24°C is the usual recommendation. Beyond that, keep curtains closed against the daytime sun, service AC units so they run efficiently, switch to LED lighting, and fix leaking taps promptly, since a single steady drip can waste hundreds of gallons a month. Bear in mind that no amount of saving touches the housing fee, which is fixed to your rent.
