Kerala bill questions
How much is the electricity bill for 100 units in Kerala?
About ₹465.00 for 100 units in a month, using the current KSERC tariff. Urban, single phase. Electricity duty and the monthly fuel surcharge are not included.
What will 200 or 300 units cost in Kerala?
Roughly ₹1,147.50 for 200 units, and ₹2,245.00 for 300 units. Use the calculator above for your exact units and load.
Are Kerala domestic slabs telescopic?
The rate table depends on your total consumption: cross the threshold and a different table applies to the whole bill. Within each table, slabs are telescopic.
How often are Kerala electricity bills issued?
Homes are billed monthly. Enter the units for one billing period.
Which tariff order are these Kerala rates from?
KSERC Tariff Order OP 18/2023 (tariff revision 2024-25 to 2026-27) and Schedule of Tariff, dated 5 December 2024, in force from 1 April 2025. A link to the PDF is in the sources box on this page.
What does this estimate leave out?
Electricity duty (10% of energy, KSEB FAQ) is not included (rate not yet confirmed from an official notice). KSEB bills most homes every two months; enter the monthly average. How KSEB applies monthly slabs to a bi-monthly reading is not published. Fuel surcharge not included (not yet published officially). The calculator adds Fuel surcharge at Rs 0.03 a unit (bills in October 2026 (for August 2026)); you can switch it off. The example bills leave it out.
Where is the consumer number on my Kerala electricity bill?
The name differs by discom. KSEB: Consumer Number. The table on this page shows where each discom prints it, when its official pages say so.
Where to find your consumer number
Your bill shows a number that identifies your connection. In Kerala the discom calls it:
| Discom | Name on the bill | Digits | Where to find it | Source |
|---|---|---|---|---|
| KSEB | Consumer Number | 13 (LT homes) | Near the top, on the line with your name. The bill number is below it. | KSEBL: Payment facility |
From the discoms’ own websites, bill guides and sample bills, read on 17 October 2026. Where the source is a sample bill, we read only its layout: the label, the place and the number of digits. A dash means the official page we read does not say. Never share your consumer number with an unknown caller or app.
