How Sri Lanka domestic electricity charges are estimated
Domestic electricity is billed in usage blocks rather than at one flat price per unit. The total units and number of billing days determine the applicable block limits, energy charges, and fixed charge.
This calculator uses the PUCSL domestic schedule effective from 11 May 2026. Tariffs can change; compare the effective date with your bill and use PUCSL's calculator for exact meter-reading dates, time-of-use tariffs, or other account types.
