Quick summary

  • The calculator does the work: Our DEWA bill calculator applies current tariff rates, tiered pricing, fuel surcharges, housing fees (where applicable), and VAT to give you an instant estimate.
  • Estimates may differ slightly: Your actual bill can vary due to meter reading dates, prorated charges, and seasonal adjustments.
  • Live tariffs: The calculator automatically updates with the latest DEWA rates—no need to track rate changes yourself.
  • What you need: Just your monthly electricity (kWh) and water (imperial gallons) usage from your last bill.

Understanding DEWA

The Dubai Electricity and Water Authority (DEWA) is the sole provider of electricity and water services in Dubai. Whether you live in an apartment, villa, or townhouse, DEWA meters your consumption and bills you monthly based on usage tiers, fixed charges, and adjustments.

Bills typically cover 28–31 days depending on your meter cycle. Knowing how each line item is calculated helps you budget accurately and spot opportunities to reduce consumption.

What makes up a DEWA bill?

Consumption charges

This is the largest part of your bill. Electricity is measured in kilowatt‑hours (kWh) and water in imperial gallons (IG). DEWA uses tiered pricing: the first units you consume cost less, and as usage increases, you move into higher‑priced tiers.

  • Electricity tiers: typically 3–4 monthly tiers by kWh.
  • Water tiers: usually 2–3 monthly tiers by gallons.
  • Sewerage: often mirrors your water charge; confirm on your bill.

Exact thresholds and rates change. Check your bill or use the calculator for current pricing.

Fixed and connection charges

  • Electricity connection fee (infrastructure and meter maintenance)
  • Water connection fee
  • Administrative/service fees

Fuel surcharge

Adjustment based on global energy prices, applied as a percentage of consumption charges. It varies over time.

Housing fee (Dubai Municipality areas)

If applicable, this is calculated as a percentage of annual rent and collected monthly (annual amount divided by 12). Some free zones and communities are exempt.

Value Added Tax (VAT)

UAE law requires 5% VAT on utilities. VAT is applied to the subtotal (consumption + fixed fees + fuel surcharge + housing fee).

Step‑by‑step: Estimate your DEWA bill

  1. Gather your usage data. From your most recent DEWA bill, note total electricity (kWh) and water (IG). If you don’t have a bill, start with rough ranges (e.g., 500–900 kWh and 1,500–3,000 IG for a 1‑bedroom; villas use more, especially in summer).
  2. Understand tiered pricing. Your usage is split across tiers: first units at a lower rate, higher units at higher rates. Water follows a similar pattern.
  3. Add fixed charges and fuel surcharge. Include connection/service fees and the current fuel surcharge (a percentage of consumption). Add sewerage (often equals the water charge).
  4. Add housing fee (if applicable). For Dubai Municipality properties, typically a percentage of annual rent divided by 12.
  5. Apply VAT (5%). Calculate 5% on the subtotal above.
  6. Or use the calculator. Enter your kWh and gallons in the DEWA bill calculator to get an instant estimate with all current rates applied automatically.

Seasonal variations: Summer vs winter

Summer (June–September)

  • AC runs for long hours; electricity use spikes.
  • Higher tiers: increased consumption pushes you into more expensive pricing bands.
  • Fuel surcharge may be higher depending on global energy prices.

Winter (November–March)

  • Minimal AC usage; consumption drops substantially.
  • Lower tiers: reduced usage keeps you in cheaper bands.

Tip: Budget for summer peaks to avoid surprises. Treat winter savings as a bonus.

Commercial vs residential properties

Residential properties (apartments, villas, townhouses) benefit from tiered pricing aimed at households. Commercial premises (offices, shops, restaurants) typically face higher per‑unit rates, different tier structures, and higher fixed charges.

If you run a business from home, confirm your classification; reclassification can significantly change your bill.

Reading your DEWA bill statement

  • Account information: Account number, property address, billing period, due date.
  • Meter readings: Previous and current readings; consumption in kWh (electricity) and IG (water).
  • Charges breakdown: Tiered consumption, fixed fees, fuel surcharge, housing fee (if applicable), sewerage, subtotal.
  • Tax and total: VAT (5%) and total amount due.
  • Payment info: Methods available and any late‑payment notes.

DEWA bill payment methods

  1. DEWA Smart App (iOS/Android): View/pay bills, set auto‑payments, track consumption, report readings.
  2. Online portal: Log in on the official website to manage and pay bills.
  3. Banks/mobile banking: Direct transfers, bill payment via apps, standing orders.
  4. Payment kiosks: Self‑service machines in malls/metro/supermarkets; accept cash/cards.
  5. Authorized centers: Exchange houses, postal offices, select retail chains.

Late payment may add a penalty and, after extended non‑payment, service disconnection.

Tips to reduce your DEWA bill

Air conditioning (largest impact)

  • Set thermostat to 24–26°C; every degree higher saves energy.
  • Clean/replace filters monthly; service units twice yearly.
  • Use timers/programmable thermostats when away or sleeping.
  • Seal doors/windows; close curtains during peak sun; use ceiling fans.

Lighting efficiency

  • Switch to LEDs; turn off unused lights; leverage natural light.

Water conservation

  • Fix leaks; install aerators/low‑flow showerheads; run full loads.
  • Collect AC condensate for plants/outdoor cleaning.

Appliances and habits

  • Upgrade to efficient models; unplug devices that draw standby power.
  • Avoid peak usage spikes to stay in lower pricing tiers.

Smart monitoring

  • Track usage in the DEWA app; compare monthly bills to spot anomalies.

Conclusion

Understanding your DEWA bill helps you budget accurately, identify savings, and avoid peak‑season surprises. While calculation involves multiple parts — tiered consumption, fixed charges, fuel surcharges, housing fees, and VAT — you don’t need to do the math manually. Use the DEWA bill calculator for an instant estimate using current rates.
