Understanding Your ZESCO Bill
Your monthly ZESCO electricity bill is made up of several components that you should understand:

- Fixed/Service Charge: A monthly standing charge for maintaining your connection, regardless of how much electricity you use.
- VAT (Value Added Tax): A 16% government tax applied to your total bill amount in Zambia.
- Levy/Surcharges: ZESCO may apply additional regulatory or rural electrification levies depending on your connection type.

💡 Tips to Reduce Your ZESCO Electricity Bill
Small changes in how you use electricity can lead to big savings over time. Here are practical tips that Zambian households can apply today:
LED bulbs use up to 80% less electricity than traditional incandescent bulbs and last much longer.
Devices on standby still consume power. Unplug chargers, TVs, and appliances when not in use.
Iron clothes in batches, run washing machines with full loads, and avoid leaving the fridge door open.
Open curtains during the day instead of using artificial lights. This can noticeably cut daytime usage.
