What Is DEWA?
DEWA (Dubai Electricity and Water Authority) is the sole provider of electricity and water services in the Emirate of Dubai. Established in 1992, DEWA supplies power to over 1.1 million customer accounts serving a population of approximately 3.6 million people. DEWA is one of the world's most efficient utilities, reporting transmission and distribution losses of just 3.3% — well below the global average of 8%.
Understanding how DEWA calculates your bill is essential for budgeting in Dubai. Unlike many countries where utility bills follow a flat rate, DEWA uses a progressive slab tariff system — meaning the unit price increases as your consumption rises. This system was designed to encourage conservation, align with the UAE's sustainability goals, and penalize excessive consumption.
Electricity Slab Tariff System
DEWA divides residential electricity consumption into four color-coded slabs. Each slab has a progressively higher rate per kilowatt-hour (kWh):
| Slab | Usage Range | Rate | Designed For |
|---|---|---|---|
| 🟢 Green | 0–2,000 kWh | 23 fils/kWh | Energy-efficient households (studio/1BR) |
| 🟡 Yellow | 2,001–4,000 kWh | 28 fils/kWh | Average family consumption (2-3BR) |
| 🟠 Orange | 4,001–6,000 kWh | 32 fils/kWh | Large apartments, small villas |
| 🔴 Red | 6,001+ kWh | 38 fils/kWh | Large villas, high consumption |
Commercial Electricity Rates
Commercial and industrial properties in Dubai do not benefit from the slab system. They pay a flat rate of 38 fils/kWh (the Red slab rate) regardless of consumption volume. This applies to all non-residential accounts including offices, retail spaces, restaurants, and warehouses.
Water Slab Tariff System
Water tariffs in Dubai follow a similar progressive structure, with three consumption slabs based on Imperial Gallons (IG) per month:
| Slab | Usage (IG/month) | Rate (fils/IG) | Metric Equivalent |
|---|---|---|---|
| Slab 1 | 0–6,000 | 3.5 fils | AED 7.70/m³ |
| Slab 2 | 6,001–12,000 | 4.0 fils | AED 8.80/m³ |
| Slab 3 | 12,001+ | 4.6 fils | AED 10.12/m³ |
Fuel Surcharge — How It Works
The fuel surcharge is a variable charge added to every DEWA bill that reflects the cost of fuel used for electricity generation and water desalination. Dubai relies on natural gas for a significant portion of its power generation, and the surcharge fluctuates with global energy prices.
- Electricity: approximately 6 fils/kWh (AED 0.060/kWh) — updated monthly
- Water: approximately 0.5 fils/IG (AED 1.10/m³) — updated monthly
The rates are set by the Dubai Supreme Council of Energy and published on the DEWA website at the start of each month. Check dewa.gov.ae for the latest rates. The surcharge appears as a separate line item on your bill, calculated by multiplying your total consumption by the applicable surcharge rate.
Sewerage Fee (New from January 2025)
Starting January 1, 2025, Dubai Municipality introduced a new sewerage fee collected through DEWA bills. This fee funds improvements to Dubai's wastewater treatment infrastructure and is being phased in over three years:
| Year | Rate (fils/IG) | Rate (AED/m³) | Impact on Average Bill |
|---|---|---|---|
| 2025 | 1.5 fils | AED 0.33 | ~AED 7–15/month |
| 2026 | 2.0 fils | AED 0.44 | ~AED 10–20/month |
| 2027 | 2.8 fils | AED 0.62 | ~AED 14–28/month |
The fee is calculated by multiplying your total water consumption (in IG) by the applicable rate and is included in the total before 5% VAT is applied.
Housing Fee (Municipality Fee)
The housing fee is one of the most significant charges on your DEWA bill — often more than the utility charges themselves. This fee is collected by DEWA on behalf of Dubai Municipality to fund public services including waste management, street cleaning, and infrastructure maintenance.
- Calculation: 5% of your annual rent ÷ 12 months
- For tenants: Based on the rent registered in your Ejari contract
- For owners: Based on the estimated annual rental value assessed by Dubai Municipality
- UAE Nationals: Exempt from this fee
| Annual Rent (AED) | Monthly Housing Fee | Annual Housing Fee |
|---|---|---|
| 30,000 | AED 125 | AED 1,500 |
| 50,000 | AED 208 | AED 2,500 |
| 60,000 | AED 250 | AED 3,000 |
| 80,000 | AED 333 | AED 4,000 |
| 100,000 | AED 417 | AED 5,000 |
| 150,000 | AED 625 | AED 7,500 |
VAT on DEWA Bills
A 5% Value Added Tax (VAT) is applied to the total DEWA bill, including electricity charges, water charges, fuel surcharges, sewerage fee, and housing fee. VAT was introduced in the UAE on January 1, 2018, and applies to utility services.

Shams Dubai — Solar Net Metering
Shams Dubai is DEWA's solar net metering program that allows home and building owners to install photovoltaic (PV) solar panels and connect them to the DEWA grid. Under this program:
- Excess solar energy generated during the day is exported to the grid and credited to your account
- Credits are applied at the same slab rate as your consumption tier
- Credits roll over to subsequent billing cycles
- No battery storage is required — the grid acts as your "virtual battery"
- DEWA offers zero connection fees for approved solar installations
To participate, you need: property owner consent, a DEWA-approved solar installer, panels and inverters meeting DEWA's technical standards, and a completed application through DEWA's Shams Dubai portal.
DEWA Green Charger — EV Charging
DEWA operates a network of EV charging stations across Dubai under the Green Charger initiative. The current tariff for public charging is 29 fils/kWh (AED 0.29/kWh). Charging at home uses your residential slab rate. DEWA plans to expand the network to support Dubai's target of 30% of vehicles being electric or hybrid by 2030.
DEWA Smart Meters
DEWA has deployed over 2.1 million smart meters (Advanced Metering Infrastructure — AMI) across Dubai, covering virtually all connections. Benefits of smart meters:
- Real-time monitoring — Track consumption through the DEWA app
- Automated billing — No estimated readings or manual meter checks
- Leak detection — Unusual water consumption patterns trigger alerts
- Remote services — Connection and disconnection without physical visits
- Usage history — Compare consumption across months and years
Energy Saving Tips for Dubai
Dubai's climate makes air conditioning the single largest contributor to electricity bills — typically 60–70% of total consumption. Here are evidence-based strategies to reduce your DEWA bill:
Air Conditioning (Biggest Impact)
- Set thermostat to 24°C — Each degree below 24°C increases consumption by 5–10%
- Clean AC filters monthly — Dirty filters force the unit to work harder
- Service units annually — Professional maintenance improves efficiency by 15–20%
- Use programmable timers — Set higher temperatures when away
- Install smart thermostats — Platforms like Honeywell or Nest learn your patterns
Lighting & Appliances
- Switch to LED bulbs — Use 75% less energy than incandescent bulbs
- Choose ESMA 5-star appliances — Look for the Emirates Authority for Standardization & Metrology rating
- Unplug standby devices — "Phantom load" can account for 5–10% of electricity use
- Use energy-efficient water heaters — Or heat water using solar in summer months
Water Conservation
- Fix leaks immediately — A dripping tap wastes 5,000+ gallons per year
- Install low-flow showerheads — Reduces water use by 30–50%
- Use efficient irrigation — Drip systems for gardens, water during early morning
- Run dishwashers and washing machines full — Avoid partial loads
