What to do if…
your rent or mortgage payment is marked unpaid even though you have proof it was sent

Short answer

Don’t pay again in panic. Gather the clearest proof you have, then contact the landlord/agent or mortgage lender in writing today and ask them to confirm receipt and pause any arrears action while the payment is traced and correctly posted.

Do not do these things

  • Don’t send a second payment “just in case” unless you can afford it and you have something in writing about how any duplicate will be returned or credited.
  • Don’t ignore arrears letters/texts or threats of charges or eviction steps just because you’re sure you paid.
  • Don’t rely on a phone call alone—follow up in writing and keep everything.
  • Don’t cancel a Direct Debit or Standing Order mid-panic if that will create additional missed payments (change it only after you’ve confirmed what went wrong).
  • Don’t send money to “new” bank details you receive unexpectedly. If details have “changed”, treat it as a potential scam until independently verified.

What to do now

  1. Make a one-page “proof bundle” (10 minutes).
    Put these together as a single PDF or a clearly labelled folder:
    • Bank statement line showing the payment (date, amount, and the payee details your bank shows).
    • Your banking confirmation/receipt screenshot.
    • The payment reference you used (rent account/tenancy ref or mortgage account number).
    • If you paid through a portal, screenshots showing “paid/processing”, confirmation ID, and date/time.
  2. Send a clear written message to the right place (today).
    Email (or portal message) the landlord/letting agent or mortgage lender with:
    • “Payment sent on [date/time], amount £[x], reference [your ref]. Proof attached.”
    • A specific ask: “Please search incoming payments by amount/date/name and correct my rent ledger/payment history.”
    • “Please pause late fees/arrears escalation while you trace and correct this.”
  3. Ask your bank what actually happened to the payment (today).
    Contact your bank and ask:
    • Was it successful, pending, rejected, or returned?
    • What exact details were used (sort code/account, payee name if recorded)?
    • What identifier they can give you (for Faster Payments, some banks show a Faster Payment ID / FPID) and what tracing/recovery options apply for that payment type.
  4. Check the two most common “sent but not credited” causes (quick wins).
    • Reference missing/wrong: Ask the recipient to search their incoming payments by amount + date + your name, then re-allocate it to your account and send you an updated ledger/statement.
    • Old/incorrect bank details: Compare what you used with what’s on your tenancy paperwork or the lender’s latest payment instructions (not a random email/text). If it’s wrong, tell your bank immediately and ask what recovery steps are available.
  5. If the issue involves a Direct Debit, use the Direct Debit Guarantee (only if relevant).
    This is for Direct Debits (where the organisation collects the money). If a Direct Debit was taken in error (wrong date/amount/after cancellation), contact your bank/building society promptly about a refund under the Direct Debit Guarantee. Keep it factual—if you receive a refund you’re not entitled to, you may need to repay it.
  6. If you suspect you were tricked into paying the wrong account, treat it as urgent.
    Contact your bank’s fraud team immediately, explain you may have sent the payment to the wrong account due to a scam/impersonation, and ask what protections and reimbursement routes may apply. Also report the incident via Report Fraud.
  7. If it’s rent with a council or housing association, ask for the process steps in writing.
    Request a current rent account statement/ledger and ask what steps they’ve taken before any legal notice. If you receive a notice or court papers, get urgent housing advice straight away and prepare to show your proof bundle.

What can wait

  • You do not need to decide today whether to move out, change banks, or “take legal action”.
  • You do not need to write a long argument. Your priority is: locate the payment, correct the ledger/payment history, stop escalation.
  • You can deal with complaints, fee reversals, and any compensation later—after the account is corrected.

Important reassurance

This kind of mismatch is common: the payment can arrive but be posted to the wrong account, stuck in a processing queue, or missed because a reference didn’t match. Having proof you sent the money puts you in a strong position—your next job is to make it easy to trace and correct, and to stop the situation escalating while that happens.

Scope note

These are first steps only—focused on preventing avoidable harm (fees, arrears markers, eviction steps) and buying time while the payment is traced and posted correctly. If the other party still insists you’re unpaid after you’ve provided proof, you may need specialist housing or debt advice.

Important note

This is general information, not legal, financial, or professional advice. If you receive formal eviction paperwork or you’re at immediate risk of homelessness or repossession, seek urgent independent advice.
