High electric bill: 6 things to check before you pay it
A higher bill is not always higher usage. Six checks that take five minutes and sometimes find a real billing error.

Before you assume you used more, spend five minutes on the bill itself. Most of the time usage explains everything. Sometimes it does not.
1. Was the read actual or estimated
The bill says which. When the meter cannot be accessed, the utility estimates. That is normal, and it produces a known effect: after several estimated months, the actual read arrives carrying everything that was under-billed.
If your recent bills alternated estimated and actual, the spike is a correction, not new consumption.
2. How many days the bill covered
This explains more increases than anything else and almost nobody checks it. The bill shows the start and end dates.
A 35-day period against a 28-day one is 25 percent more usage by itself, with nothing having changed at home. Compare cost per day, not the total.
3. Whether the rate changed
Rates change, and seasonal structures can shift what you pay per unit. If your plan has time-of-use pricing, the same total usage costs more when it happens in peak hours.
4. One-off charges
Reconnection, meter work, deposits and payment arrangements appear as separate lines. They are temporary, and they inflate the current bill.
5. Taxes and municipal fees
Part of what appears on a utility bill is not the utility's charge at all. Local surcharges are collected there for convenience, and disagreements about them belong with the local authority.
6. The usage history graph
Every bill carries it, and it is the fastest diagnostic available.
| Pattern | Usual meaning |
|---|---|
| One isolated spike | Longer billing period, rate change or a one-off charge |
| Gradual climb over months | New habit, new appliance, or equipment losing efficiency |
| Dip then spike | Estimated reads followed by an actual one |
| High and steady | The household's profile, not an error |
If there is an error
Open a case with the utility asking for a billing review and, if warranted, a meter test. Keep the case number.
And if there is no error, the conversation moves: the usage has a source, and it usually sits in a handful of appliances. The calculator in appliances that use the most electricity finds it in a minute.
Frequently asked questions
Should I withhold payment while I dispute?
Generally no. Non-payment can lead to disconnection and collection activity even with a dispute open. Pay and pursue a credit, or arrange something with the utility.
How many days should a billing period cover?
Usually around 30, but it varies. A period noticeably longer than the previous one explains a surprising share of unexplained increases.
What is an estimated read?
When the meter cannot be read, the utility estimates usage. After several estimated months, the true read arrives carrying the accumulated difference.
Can I ask for the meter to be tested?
Yes. Utilities have a process for meter accuracy testing. Ask about any fee if the meter turns out to be accurate.
If there is no error, the usage has a source. The calculator shows which appliance.
