What is the electricity unit price in Sri Lanka in 2026?

There is no single unit price — what a unit costs depends on how many units the whole month used, because the total picks the band and the band sets every rate. On a 30-day domestic (D-1) cycle the schedule approved by PUCSL with effect from 2026-05-11, and still in force on 2026-09-23, is: Consumption 0–60 kWh per month — 1–30 kWh at Rs 5.00 (fixed Rs 80), 31–60 kWh at Rs 9.00 (fixed Rs 210). Consumption above 60–180 kWh per month — 1–60 kWh at Rs 14.00, 61–90 kWh at Rs 20.00 (fixed Rs 400), 91–120 kWh at Rs 28.00 (fixed Rs 1,000), 121–180 kWh at Rs 44.00 (fixed Rs 1,500). Consumption above 180 kWh per month — 1–180 kWh at Rs 32.50, above 180 kWh at Rs 100.00 (fixed Rs 2,500). The full table, including what each of those bands comes to as a monthly bill, is in the unit price table on this page. EDL (formerly CEB) and LECO bill the identical schedule.

How is the electricity bill calculated in Sri Lanka?

Your total consumption for the month picks one of three consumption bands, and every unit is then charged on that band's rate ladder. A fixed charge is added, set by the block your bill stops in. Because the band is chosen by the whole month's consumption, crossing a band boundary re-prices every unit you used, not just the extra one. CEB and LECO bill the identical PUCSL-approved schedule.

What is the CEB domestic tariff from 11 May 2026?

On a 30-day cycle there are three bands. Band 1 (0–60 units): the first 30 units at Rs 5.00 with a Rs 80 fixed charge, units 31–60 at Rs 9.00 with a Rs 210 fixed charge. Band 2 (above 60 up to 180 units): 0–60 at Rs 14.00, 61–90 at Rs 20.00 (fixed Rs 400), 91–120 at Rs 28.00 (fixed Rs 1,000), 121–180 at Rs 44.00 (fixed Rs 1,500). Band 3 (above 180 units): the first 180 units at Rs 32.50 and everything above 180 at Rs 100.00, with a Rs 2,500 fixed charge. LECO bills the same schedule.

Why does my electricity bill jump so much when I cross 60 units?

Because the band is chosen by your total consumption. At 60 units you are in band 1 and the bill is Rs 630. At 61 units you move into band 2, which re-prices your first 60 units at Rs 14.00 instead of Rs 5.00 and Rs 9.00, and raises the fixed charge from Rs 210 to Rs 400 — Rs 1,260 in total. One extra unit costs Rs 630 in practice. The same happens at 180 units, where the bill goes from Rs 6,420 to Rs 8,450.

What is the fixed charge on a Sri Lankan electricity bill in 2026?

It is a monthly charge for the connection itself, on top of the units. It steps with the block your bill stops in: Rs 80 up to 30 units, Rs 210 from 31 to 60, Rs 400 from 61 to 90, Rs 1,000 from 91 to 120, Rs 1,500 from 121 to 180, and Rs 2,500 above 180. There is no minimum bill in the current schedule — a domestic connection that uses nothing pays the Rs 80 fixed charge and no more.

Is there still a Rs 150 minimum bill?

No. The Rs 150 minimum-bill slab belonged to the March 2025 determination and does not appear in the schedule approved from 11 May 2026. A domestic connection with zero consumption is billed the Rs 80 band-1 fixed charge. If you are reading a Rs 150 minimum anywhere, it is from a superseded tariff.

How do I read my CEB or LECO meter and estimate my next bill?

Subtract the previous meter reading from today's — the difference is the units consumed in that period. Enter that figure above. If your cycle is not 30 days, switch the billing-cycle dropdown: the block limits scale with the number of days, which is how PUCSL's own calculator handles it.

Does the calculator handle bi-monthly (60-day) billing correctly?

Yes, and it follows PUCSL's published method: every block limit is scaled by the number of billing days, so a 60-day cycle is billed on limits of 60/120/180/240/360 units rather than 30/60/90/120/180, and one fixed charge is applied to the bill rather than one per 30 days. A household that used 120 units over 60 days is therefore still in band 1 and pays Rs 1,050, not the Rs 3,280 that 120 units in a single month would cost.

What about industrial, hotel time-of-use, or domestic time-of-use tariffs?

The Hotel (H-1) and General Purpose (GP-1) categories here are the volume-differentiated retail tariffs: one flat rate on every unit, chosen by whether the month is at or below the threshold (300 units for H-1, 180 for GP-1). Demand-metered industrial and commercial supplies need a kVA reading and belong in the industrial bill calculator. The domestic time-of-use tariff needs three separate peak, day and off-peak meter readings and has its own tool.

Is the LECO tariff the same as the CEB tariff?

Yes, to the rupee. PUCSL approves one retail schedule and every distributor bills it, so there is no separate LECO rate to look up. LECO publishes the schedule itself, on its own tariff page, as the rates approved with effect from 11 May 2026 — the same bands, blocks, rates and fixed charges this page uses. LECO serves urban Western Province towns (Kotte, Moratuwa, Kelaniya, parts of Negombo); the rest of the country is served by EDL, formerly CEB. The utility toggle above changes nothing in the arithmetic; it is there so the result mirrors the brand on your printed bill.

Is an EDL bill calculator different from a CEB bill calculator?

No. The Ceylon Electricity Board was dissolved under the Sri Lanka Electricity Act No. 36 of 2024, and its distribution business passed to Electricity Distribution Lanka (Pvt) Ltd — EDL — with effect from 9 March 2026. The name on the bill and the self-service site changed; the tariff did not, because PUCSL still approves it. So an estimate from this page is an EDL estimate and a CEB estimate at the same time. If you follow an old ebill.ceb.lk or cebcare.ceb.lk link you will land on EDL's portal at edlcare.edl.lk.

How do I check my CEB electricity bill online?

Through EDL's own self-service portal, EDLCare, at edlcare.edl.lk — it shows the outstanding balance on an account, and it is also where you register for the e-bill so each month's bill arrives by email. Bills are paid at payment.ceb.lk, which EDL still links itself, and the 24-hour call centre is 1987. This page cannot do any of that: it estimates a bill from the units on your meter and never asks for an account number, an NIC or a meter serial.

How do I check my LECO bill online?

View the e-bill at ebill.leco.lk. If you are not registered yet, LECO's e-billing page explains the service and there is an online application form at lecoapp.leco.lk; payment options and collection centres are listed on leco.lk, and the customer call centre is 1910. Again, this page only estimates from a meter reading — it has no access to your account and should never be given your account number.

How accurate is this against an actual printed bill?

The engine reproduces PUCSL's own published bill calculator exactly across every unit count from 0 to 2,000, on both 30-day and 60-day cycles. Two things can still make a printed bill differ: a fee added by your payment channel (LankaQR, PayHere, a bank standing order — none of which are part of the tariff), and any backbilled adjustment on an unusual cycle. If a normal cycle differs by more than a few rupees, email me the bill image and I will look at it.

When were these tariffs last verified?

The schedule here was read directly from PUCSL's determination "Decision on Electricity Tariffs", approved with effect from 2026-05-11, and re-checked on 2026-09-23. PUCSL revised the retail tariff three times in the year to September 2026, so this page is re-checked quarterly and whenever a revision is announced.

CEB & LECO electricity unit price table (2026)

These are the domestic (D-1) unit prices in force in Sri Lanka right now: the schedule PUCSL approved with effect from 11 May 2026, re-read from the determination on 2026-09-23. PUCSL reviewed tariffs again at the end of July 2026 and left every figure unchanged, and it has published no decision since. EDL (formerly CEB) and LECO bill the identical schedule, so there is one unit price table, not two.

Read it band first. Your total consumption for the cycle picks the band; the band's blocks then price every unit you used. That is why there is no single “unit price” in Sri Lanka: the cheapest and the dearest block in the table are an order of magnitude apart, and which of them applies to you is decided by the month's total, not by the unit.

Domestic (D-1) tariff for a 30-day billing cycle, PUCSL Annex-2, effective 11 May 2026. Billed identically by EDL (formerly CEB) and by LECO.
Consumption band	Block	Unit price (per kWh)	Fixed charge
Consumption 0–60 kWh per month	1–30 kWh	Rs 5.00	Rs 80.00
Consumption 0–60 kWh per month	31–60 kWh	Rs 9.00	Rs 210.00
Consumption above 60–180 kWh per month	1–60 kWh	Rs 14.00	—
	61–90 kWh	Rs 20.00	Rs 400.00
	91–120 kWh	Rs 28.00	Rs 1,000.00
	121–180 kWh	Rs 44.00	Rs 1,500.00
Consumption above 180 kWh per month	1–180 kWh	Rs 32.50	—
Consumption above 180 kWh per month	Above 180 kWh	Rs 100.00	Rs 2,500.00

A dash means the schedule prints no fixed charge for that block. Those blocks are rungs on the ladder only — a bill can never stop in one, because the band starts above that block's ceiling.

What those rates come to as a monthly bill

The same table, priced. Every row below is the calculator above run on a 30-day domestic cycle, so these are the numbers the rate table actually produces.

Units (kWh)	Energy charge	Fixed charge	Total bill	Average per unit
30	Rs 150	Rs 80	Rs 230	Rs 7.67
60	Rs 420	Rs 210	Rs 630	Rs 10.50
61	Rs 860	Rs 400	Rs 1,260	Rs 20.66
90	Rs 1,440	Rs 400	Rs 1,840	Rs 20.44
120	Rs 2,280	Rs 1,000	Rs 3,280	Rs 27.33
180	Rs 4,920	Rs 1,500	Rs 6,420	Rs 35.67
181	Rs 5,950	Rs 2,500	Rs 8,450	Rs 46.69
250	Rs 12,850	Rs 2,500	Rs 15,350	Rs 61.40
400	Rs 27,850	Rs 2,500	Rs 30,350	Rs 75.88

Note the two pairs: 60 and 61 units, and 180 and 181. One extra unit changes the band, the band re-prices the whole month, and the bill jumps by hundreds or thousands of rupees. That is the single most useful thing to know about this tariff.

LECO bill calculator — is the LECO tariff different?

No. PUCSL approves one retail electricity tariff for the whole country and every distributor bills it, so there is no separate LECO rate to hunt for: the figure the calculator above gives you is your LECO bill. LECO says so itself — its published tariff page prints the same bands, blocks, unit prices and fixed charges as the table above, as the rates approved with effect from 11 May 2026. Those two sources were read against each other on 2026-10-01 and agree on every figure.

LECO — Lanka Electricity Company — distributes to urban Western Province towns: Kotte, Moratuwa, Kelaniya and parts of Negombo among them. The rest of the island is served by EDL. Which of the two sends your bill decides the logo on the envelope and the call centre you ring; it does not change a single rate.

And if your bill says EDL. The Ceylon Electricity Board no longer exists as a corporate body. Under the Sri Lanka Electricity Act No. 36 of 2024, a gazette (No. 2478/41) split the CEB into successor companies and transferred its distribution business to Electricity Distribution Lanka (Pvt) Ltd — EDL — with effect from 9 March 2026. The tariff was untouched by that: PUCSL is still the regulator and still approves the schedule, which is why the May 2026 rates survived the handover intact. So “EDL bill calculator”, “CEB bill calculator” and “LECO bill calculator” are all the same question, and this page is the answer to all three.

How it works

Sri Lanka's retail electricity tariff is set by the Public Utilities Commission of Sri Lanka (PUCSL)under the Sri Lanka Electricity Act No. 36 of 2024. Ceylon Electricity Board (CEB) — whose distribution business has been EDL since March 2026 — and Lanka Electricity Company (LECO) bill the identical approved schedule, so the calculator returns the same number for either utility. Every figure on this page was read from PUCSL's determination Decision on Electricity Tariffs, Annex-2, column “Approved Tariff, Effective from 11th May 2026”.

The domestic schedule has three consumption bands, and the band is a property of the whole month, not of any single unit. Total the units for the cycle; that total picks the band. Inside the band, units are charged block by block on the band's own ladder. One fixed charge is then added — the one printed against the block the bill stops in, which steps at 30, 60, 90, 120 and 180 units.

Read the meter at both ends of the billing period. The difference is your units consumed (kWh).
Find the band whose total-consumption range contains that number: 0–60, above 60 up to 180, or above 180.
Charge the units falling in each of that band's blocks at the block's rate, and sum them — that is the energy charge.
Add the fixed charge printed against the block the bill stopped in.
Add a fuel adjustment charge if one is in force. The May 2026 determination sets none, so the rate is 0%.

The consequence is the part worth knowing. Because the band is chosen by the total, crossing a boundary re-prices every unit you used. At 60 units the bill is Rs 630; at 61 it is Rs 1,260, because the first 60 units move from Rs 5.00 and Rs 9.00 to Rs 14.00 and the fixed charge steps from Rs 210 to Rs 400. The second cliff is at 180 units, where Rs 6,420 becomes Rs 8,450. Those two points are where trimming a few units is worth real money.

What changed on 11 May 2026. The previous schedule billed domestic customers on six retroactive slabs with fixed charges from Rs 150 to Rs 2,000 and a Rs 150 minimum bill. The current determination replaced that with the three bands below. There is no minimum bill any more: a connection that uses nothing pays the Rs 80 band-1 fixed charge. PUCSL absorbed a Rs 15 billion government subsidy so that consumption up to 180 units was not increased at all; the 18.1% revision falls on consumption above 180 units, which is where the Rs 32.50 / Rs 100.00 band comes from.

Still the current schedule.PUCSL reviewed tariffs again for the third quarter of 2026. That decision, effective 31 July 2026, found the forecast revenue deficit “minimal and within the error margin” and resolved to continue with the existing end-user tariffs until the next revision. It publishes no tariff table of its own, so the rates on this page are the 11 May 2026 ones, re-confirmed by a later review rather than replaced. If you want to check for yourself, PUCSL lists every determination on its end-user tariff decisions page.

Cycles that are not 30 days.Annex-2 is written for a 30-day cycle. PUCSL's own bill calculator scales every block limit by the number of billing days — limit × days ÷ 30, rounded down — and applies one fixed charge per bill rather than one per 30 days. This page does the same, so a 60-day reading is billed on limits of 60/120/180/240/360 units. A household that used 120 units over 60 days is in band 1 and pays Rs 1,050, not the Rs 3,280 that 120 units in a single month would cost.

The engine is checked two ways. It is written against the band data structure, and a second, independent if/then ladder transcribed straight off the printed table must agree with it to the rupee on every reference case. Both were then compared against PUCSL's own published calculator across every unit count from 0 to 2,000 on both cycle lengths, and they agree on all of them.

The rates themselves, with every block and fixed charge, are in the unit price table above.

Block 31–45: 15 × Rs 9.00 = Rs 135
Energy charge: Rs 285
Bill stops in block 31–60 → fixed charge Rs 210
Total: Rs 495 · Effective: Rs 11.00/kWh

Suburban Kandy family with one air conditioner

165 kWh(30-day cycle)

Total for the cycle: 165 kWh
165 is above 60 and up to 180 → band 2 (every unit re-prices)
Block 1–60: 60 × Rs 14.00 = Rs 840
Block 61–90: 30 × Rs 20.00 = Rs 600
Block 91–120: 30 × Rs 28.00 = Rs 840
Block 121–165: 45 × Rs 44.00 = Rs 1,980
Energy charge: Rs 4,260
Bill stops in block 121–180 → fixed charge Rs 1,500
Total: Rs 5,760 · Effective: Rs 34.91/kWh

The 180-unit cliff — one unit, Rs 2,030

181 kWh(30-day cycle)

At 180 kWh: band 2, energy Rs 4,920 + fixed Rs 1,500 = Rs 6,420
At 181 kWh the total crosses into band 3, which has its own ladder
Block 1–180: 180 × Rs 32.50 = Rs 5,850
Block above 180: 1 × Rs 100.00 = Rs 100
Energy charge: Rs 5,950
Fixed charge (band 3): Rs 2,500
Total: Rs 8,450 — Rs 2,030 more than the bill at 180 units exactly

How to check your actual CEB, EDL or LECO bill

This page estimates a bill from a meter reading. It cannot look your account up, and it is not trying to: it asks for a number of units and nothing else. Never type an account number, an NIC or a meter serial into a calculator — not this one, which has no field for it, and not any other. To see the bill that was actually issued to you, go to your own operator:

EDL (formerly CEB)

Everywhere except the LECO towns

Call centre: 1987

LECO

Urban Western Province — Kotte, Moratuwa, Kelaniya, parts of Negombo

Call centre: 1910

Every link and both numbers above were read off the operators' own websites on 2026-10-01 and from nowhere else. Old ebill.ceb.lk and cebcare.ceb.lklinks now redirect to EDL's portal, following the March 2026 handover. If one of these channels moves, email me and I will fix it.
