Electric Bill Suddenly Doubled? A 7-Step Investigation Checklist
Use this structured checklist when your electricity bill jumps sharply so you can verify charges before the due date.
Start with a same-period comparison
Compare current bill against previous month and same month last year. This separates normal seasonality from unexplained variance.
Check pricing components before usage assumptions
A large jump can come from rate or fixed-fee changes even when consumption is flat. Verify standing charges, unit rate, and policy surcharge lines first.
Audit read quality and billing days
Estimated reads and abnormal billing-day counts can distort totals. Confirm meter read type and period length before escalating.
- Read type: estimated vs actual
- Billing days outlier
- Unexpected tariff or contract update
Escalate with exact deltas
Support teams respond faster when you point to exact lines and amounts. Include your expected range and request line-level justification.
Key takeaways
- Validate period boundaries and read type before judging totals.
- Separate usage, fixed charges, and taxes to isolate true root cause.
- Use line-item deltas and supporting history in all disputes.

FAQ
Is a 30% increase always suspicious?
Not always. Start with weather and occupancy changes, then verify rate and fixed-fee lines before concluding it is an error.
What should I check first on the bill PDF?
Billing period, read type, total usage, unit rate, and fixed charges.
Can I dispute if only one line item looks wrong?
Yes. A focused, line-item dispute is often more effective than disputing the whole invoice.
