How to Read Your Electricity Bill (and Spot Mistakes)
Updated · 5 min read
An electricity bill looks crowded, but only a few lines decide most of the amount. Once you know them you can check the total yourself and notice when something looks wrong.
The lines that matter
- Reference or consumer number: identifies your connection. You need it to see a duplicate bill online or to complain.
- Previous and present reading: the meter numbers. Present minus previous is the units used, normally in kWh.
- Units consumed: compare with last month. A sudden jump with no change at home is worth a question.
- Tariff or slab: many countries charge a higher price per unit once you pass certain limits. A few extra units can therefore cost much more than the average rate.
- Fixed and fuel adjustments, taxes: extra items added by the regulator and the government. They change from month to month.
- Due date and late payment amount: paying after the due date adds a surcharge.
A quick check you can do
- Subtract the previous reading from the present one and compare it with the units on the bill.
- Divide the amount by the units to get your price per unit. Compare that with last month.
- Look at the meter yourself. If the reading on the bill is far from the meter, report it.
Our electricity bill calculator helps you estimate the cost of appliances, and the bill tracker keeps each month so you see the pattern.
If the bill looks wrong
Take a photo of the meter, keep the bill, and contact your electricity company's complaint centre with the reference number. Ask for the complaint number and keep it. Many companies also have a regulator you can approach if the complaint is not resolved.
