What to do if…
a cash deposit is credited for less than the amount you handed over

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Keep the receipt, paying-in slip, and any machine confirmation, then contact the bank through a trusted route as soon as you notice. Ask the bank to log a cash deposit discrepancy and give you a reference number.

Do not do these things

  • Don’t throw away the receipt, paying-in slip, envelope, or machine confirmation.
  • Don’t rely on memory alone if you have a written amount, receipt, or account entry to compare.
  • Don’t post screenshots, account numbers, card details, or branch staff names online.
  • Don’t keep trying to repeat the same deposit at a machine that has already shown an error.
  • Don’t guess or accuse in the first report; give the bank the facts it needs to check the records.
  • Don’t hand over original documents unless you have a copy or photo for yourself.

What to do now

  1. Write down the key facts. Note the date, time, branch or machine location, amount you handed over, amount credited, and any receipt, paying-in slip, machine, or transaction reference.
  2. Preserve the proof. Keep the receipt flat and readable. Take clear photos of the receipt, paying-in slip, machine confirmation, and the account entry showing the lower credit.
  3. Check whether the shortfall is still showing. Look at your balance and recent transactions in the banking app or online banking. Do not assume it has corrected unless the account entry now shows the full amount.
  4. Contact the bank through a trusted route. Use the number on the back of your card, secure in-app messaging, a branch, or the bank’s official website. Say: “I made a cash deposit and the credited amount is lower than the cash I handed over. Please log a cash deposit discrepancy.”
  5. Get a reference number. Ask for the complaint or case reference, the date it was logged, and what evidence the bank wants from you. Write down the name or team you spoke to if they give it.
  6. If it was a branch counter deposit, ask for a branch review. Ask the bank to check the transaction record, the paying-in slip or teller entry, and the relevant branch cash balancing for that day. You can also ask whether any other records can be reviewed under the bank’s process.
  7. If it was an ATM or cash deposit machine, ask for a machine-deposit investigation. Ask the bank to check the machine record or journal, the deposit module, and the cash balancing for that machine.
  8. Put the report in writing. Use secure message, email, letter, or the bank’s published complaints route. Include the amount deposited, the amount credited, the date and time, the location, references, and copies or photos of the proof.
  9. Ask about knock-on harm. If the shortfall has caused or may cause missed payments, charges, or an overdraft problem, ask the bank to note that and explain how it will consider those charges if the deposit error is confirmed.
  10. Protect essentials while it is being checked. If the missing amount affects rent, mortgage, utilities, payroll, or another urgent bill, contact the biller and ask for a short hold while the bank investigates.

What can wait

  • You do not need to decide today whether to switch banks.
  • You do not need to decide today whether to take legal action.
  • You do not need to prove fault before you report it; you need to preserve the proof and get the discrepancy logged.
  • You do not need to contact the Financial Ombudsman Service before giving the bank a chance to respond.
  • If you are unhappy with the bank’s final response, or the bank does not send a final response within the relevant time limit, you can ask the Financial Ombudsman Service whether it can look at the complaint. For most complaints this is often eight weeks, but some complaint types can have shorter response times.
  • If you get a final response from the bank, check the date on it; you usually have six months from that date to refer the complaint to the Financial Ombudsman Service.

Important reassurance

A cash deposit discrepancy is something a bank can usually check against transaction records, branch or machine records, and cash balancing. The most useful first step is to make a clear report and keep your evidence safe.

Scope note

These are first steps only. If the bank disputes what happened or the missing amount is significant, later decisions may need help from a complaints adviser, the Financial Ombudsman Service, or another suitable specialist.

Important note

This is general information, not legal, financial, or professional advice. Bank processes and records vary by deposit method, bank, branch, machine, and account type.
