• 91 – 120 kWh: Rs. 20.00 per unit
• 121 – 180 kWh: Rs. 33.00 per unit
• Above 180 kWh: (Ensure you include this slab if applicable, as it’s common for tiered systems)

Apart from unit charges, the CEB bill also includes:

• Fixed Charges: E.g., Rs. 1,500.00 per month (varies by category and consumption slab)
• Social Security Contribution Levy (SSCL) Tax: Applicable government tax included in the final bill.
• Fuel Adjustment Charge: If applicable (less common now, but good to acknowledge).

Factors Affecting Your Electricity Bill

Several factors influence your electricity bill in Sri Lanka:

• Appliance Usage: High-energy-consuming appliances like air conditioners, refrigerators, and water heaters contribute significantly to your bill.
• Time of Use: While not universally applied to all domestic tariffs, some commercial or industrial tariffs may have peak-hour charges.
• Inefficient Appliances: Old and inefficient electrical devices consume more power, increasing your costs.
• Seasonal Variations: Increased use of fans and air conditioners during hotter months can lead to higher consumption.

Tips to Reduce Your CEB Electricity Bill

Reducing electricity costs doesn’t require drastic changes; small adjustments can make a big difference. Here are some practical energy-saving tips:

1. Use Energy-Efficient Appliances

• Switch to LED bulbs instead of incandescent ones.
• Use inverter air conditioners and refrigerators that consume less electricity.

2. Unplug Devices When Not in Use

Many appliances continue to consume power when plugged in, even if turned off (phantom load). Unplug chargers, TVs, and kitchen appliances when not in use.

3. Optimize Cooling and Heating

• Set your air conditioner temperature to 24-26°C for optimal efficiency.
• Use ceiling fans to distribute cool air, allowing you to set the AC to a slightly higher temperature.

4. Reduce Peak Hour Consumption

Avoid running high-energy-consuming devices during peak hours when electricity demand is highest (e.g., typically early evening).

5. Conduct Regular Maintenance

• Clean air conditioner filters regularly.
• Service refrigerators and other heavy appliances to maintain efficiency.
