Hit by a surge-priced utility bill?

Check your bill free — file it yourself, or let us file it for you.

Check my bill Write a complaint letter

Can’t pay right now, or facing a shutoff?

  • Call your utility today. Ask for a payment plan and whether there is shutoff protection while you dispute the bill.
  • Call 211 or visit 211.org for local help paying bills.
  • Apply for LIHEAP, the federal program that helps pay heating and cooling bills.

How it works

  1. Check your bill

    Enter a few numbers from your bill, or upload it. We flag signs of a price surge, estimated readings, and charges that don’t add up. Your bill stays on your device.

  2. Get a ready-to-send letter

    We fill in a complaint or refund-request letter with what we found. You can edit it, then copy, print, or email it.

  3. File with your state

    If the utility doesn’t fix it, our state-by-state guide links you straight to your utility commission’s complaint page.
