How to actually cut your electricity bill in Bangladesh
Generic advice like 'turn off lights when not in use' rarely moves the needle. This guide walks through a structured audit, a 30-day plan, and appliance-level comparisons so you can find where your real units are going and fix the largest ones first.
Most electricity bills in Bangladeshi homes and small businesses are dominated by two or three appliances, not by dozens of small ones. Cooling and water heating alone commonly account for 50–70% of a household's units. The fastest way to cut a bill meaningfully is to find and fix those few big consumers rather than chasing every switch in the house.

The room-by-room audit method
Before changing anything, spend fifteen minutes per room and answer three questions: what's plugged in, how many hours a day does it actually run, and does its rated wattage match what you'd expect.
- List everything with a plug or a switch — including things you forget, like a router, aquarium pump, CCTV recorder or security light.
- Note the wattage from the rating plate or nameplate sticker (usually on the back or base of the appliance).
- Estimate real daily hours of use — not "on all day" but a realistic number based on your habits, or use the appliance cost calculator to convert watts and hours into monthly units and taka instantly.
- Flag anything that runs 24/7 — fridge, router, IPS/inverter, aquarium equipment, CCTV — since these accumulate units even while you sleep or are away.
- Rank by monthly cost, not by how often you notice the device. A 2kW geyser used for 20 minutes a day often costs more than a laptop run for 8 hours.
The 30-day action plan
Spread changes over a month so you can see which ones actually move your meter reading.
| Period | Action |
|---|---|
| Days 1–3 | Photograph every appliance's rating plate and note its wattage. Read your meter daily at the same time to get a true baseline. |
| Days 4–7 | Walk each room and list every device that stays plugged in 24/7 — fridge, router, IPS, set-top box, chargers. This is your standby load. |
| Days 8–10 | Kill unnecessary standby loads at the switchboard: unplug unused chargers, turn off set-top boxes and printers at the wall overnight. |
| Days 11–14 | Service AC filters, clean fridge condenser coils, and check door/window seals for cooling leaks. |
| Days 15–18 | Reset AC to 24–26°C, fridge to 3–5°C, freezer to −18°C, and geyser thermostat to the lowest comfortable setting. |
| Days 19–22 | Replace remaining CFL/incandescent bulbs with LEDs, starting with the longest-burning fixtures (porch, staircase, kitchen). |
| Days 23–26 | Reschedule washing, ironing, water pumping and battery charging outside the 5–11 PM peak window. |
| Days 27–30 | Re-read the meter, compare against your Day-1 baseline, and note which changes had the biggest measurable effect before repeating the cycle. |
Highest-impact saving tips
Run the AC at 24–26°C instead of 18°C
৳400–৳1,200 per month on a 1.5-ton unitEvery degree you lower the thermostat adds roughly 6% to compressor runtime. 25°C with a ceiling fan feels the same as 21°C without one, and the fan costs about ৳12 a month to run.
Service the AC filter every 6–8 weeks in summer
5–12% of cooling energyDust on the evaporator forces longer compressor cycles. A ten-minute filter wash is the cheapest efficiency upgrade available in a Dhaka summer.
Set the fridge to 3–5°C and freezer to −18°C
5–10% of household consumptionColder than that adds no food safety benefit. Also leave 5 cm of clearance behind the fridge so the condenser coil can shed heat.
Replace every CFL and incandescent with LED
৳50–৳150 per bulb per monthA 60W incandescent burning six hours a day costs about ৳95 a month at mid-slab rates. A 9W LED doing the same job costs about ৳14.
Kill standby loads at the switchboard
৳100–৳300 per monthSet-top boxes, old TVs, chargers, printers and always-on IPS units draw 3–15W each around the clock. Ten such devices are roughly 30 units a month.
Shift heavy loads out of the 5–11 PM peak window
25–40% on shifted units for TOU metersWashing machines, water pumps, ironing and battery charging can all be moved. If you are on a flat residential slab this still helps the grid and reduces load-shedding risk.
Lower the geyser thermostat and switch it off between uses
৳600–৳1,500 per month in winterA 2 kW geyser left on all day can quietly add 200+ units. Heating for 20 minutes before a shower gives the same result.
Watch the slab boundary near month end
৳200–৳500 in borderline monthsCrossing from 300 to 301 units, or from 400 to 401, moves the extra units to a higher rate. If your prepaid meter shows 395 units on the 27th, defer the laundry.
Fix the power factor if you run motors
Avoids a 5–15% penalty on commercial billsShops and small factories with pumps, compressors or lifts get penalised below 0.95 power factor. A capacitor bank usually pays back within a year.
Read your own meter on the same date every month
Catches estimated-bill errors earlyA photo of the display on the 1st of each month is the strongest evidence you can bring to a billing dispute, and it tells you your true daily average.
Appliance efficiency comparison
Comparing rated wattage side by side shows where a small swap makes a large difference and where it barely matters. Figures below use each appliance's typical daily hours over a 30-day month.
Lighting: LED vs CFL vs incandescent
| Bulb | Watts | Units / month (6h/day) |
|---|---|---|
| LED bulb 9W | 9W | 1.6 |
| LED tube light 20W | 20W | 3.6 |
| CFL bulb 20W | 20W | 3.6 |
| Incandescent bulb 60W | 60W | 10.8 |
Air conditioners: inverter vs non-inverter
| Unit | Watts | Units / month (6h/day) |
|---|---|---|
| Air conditioner 1.0 ton (non-inverter) | 1200W | 216 |
| Air conditioner 1.5 ton (non-inverter) | 1750W | 315 |
| Air conditioner 1.5 ton (inverter) | 1150W | 207 |
Fans: regular vs BLDC
| Fan | Watts | Units / month (12h/day) |
|---|---|---|
| Ceiling fan (regular) | 75W | 27.0 |
| Ceiling fan (BLDC / energy saving) | 32W | 11.5 |
| Table / pedestal fan | 55W | 13.2 |

Seasonal advice
- Summer (March–June): Cooling dominates. Service AC filters every 6–8 weeks, use ceiling fans alongside AC so you can run the thermostat 2–3°C warmer, close curtains during peak sun hours, and avoid running the AC and a large kitchen appliance simultaneously to reduce sanctioned load stress.
- Monsoon (July–September): Humidity, not heat, is the main driver — a dehumidifier or AC's dry mode uses less power than full cooling mode for comfort. Check for water ingress near switchboards and outdoor units, which can cause hidden leakage current and inflated readings on older meters.
- Winter (November–February): Geysers and space heaters become the largest load. Heat water only for the duration needed rather than keeping a geyser on standby, and prefer a flow-heater over a storage tank if your usage is only a few short showers a day.
Key takeaways
- • Cooling and water heating usually dominate a Bangladeshi bill — fix those first.
- • An audit that tracks watts × hours beats guessing which appliance is expensive.
- • Spread changes over 30 days so you can measure which ones actually worked.
- • Inverter AC and LED lighting have the best payback of any single swap.
- • Seasonal swings in usage are normal; unexplained spikes outside season are worth investigating.
Frequently asked questions
How much can a typical household realistically save?
Households that complete the full 30-day plan commonly see a 15–25% drop in units, mostly from AC thermostat changes, standby elimination and LED replacement. The exact figure depends heavily on how much cooling load you started with.
Is it worth buying an inverter AC just to save on the bill?
An inverter 1.5-ton unit uses roughly 30-40% less energy per hour of steady-state cooling than a non-inverter unit of the same capacity. At Dhaka summer usage (6+ hours a day), the extra purchase cost is often recovered within 2–3 cooling seasons — check the wattage comparison table above for your specific model.
Do energy-saving power strips actually help?
They help mainly by making it easy to cut standby loads (TV, set-top box, speakers) with one switch instead of unplugging each device. The saving comes from you actually using the switch, not from any special feature of the strip itself.
Should I unplug my fridge overnight to save power?
No — this is unsafe for food storage and doesn't save meaningfully, because the compressor cycles on and off anyway. Instead, keep the door seal clean, don't overfill it, and leave clearance behind it for heat to escape.
Why did my bill not drop even after I changed my habits?
Check whether you crossed a slab boundary from other unrelated usage, whether a new appliance was added, or whether the bill includes arrears or a surcharge from a previous cycle. Use the appliance cost calculator to isolate which device is driving consumption.
