Complain to the bank or financial business first

The Financial Ombudsman Service requires customers to give the business an opportunity to resolve the problem before the Ombudsman investigates. Use the provider's formal complaint route rather than relying only on ordinary customer service messages.

State the account or payment involved, the relevant dates, what went wrong and what remedy is requested. Include receipts, statements or other evidence of financial loss where available.

Ask for a complaint reference and keep copies of all messages. A clear complaint record is easier to escalate than a long history of unstructured support conversations.

For 'Complain to the bank or financial business first', apply the rule to the exact amount, date, provider and payment or account type involved. The page-specific control is that the complaint route depends on the issue type, evidence, response deadline and the remedy the customer is asking the firm to provide. Save the live source or provider wording used for section 1, because a small change in timing, eligibility, fee, account status or support route can change the practical result without changing the broad banking label.

Use a complaint that is misclassified between a payment-service case and an ordinary account complaint. Compare the correct response deadline and keep the final-response date for Ombudsman escalation.

Payment-service and fraud complaints use shorter response times

The Financial Ombudsman currently says a business has 15 days to consider complaints about fraud and scams, payment services such as bank transfers or Direct Debits, and electronic money. In some payment cases, a further response can be required within 35 days where the firm cannot provide the final answer immediately.

Do not assume the standard eight-week timetable applies to every bank complaint. Identify whether the complaint is about a payment service, fraud or another account issue.

Record the date the formal complaint was submitted so you know when escalation becomes available if the business does not respond in time.

For 'Payment-service and fraud complaints use shorter response times', apply the rule to the exact amount, date, provider and payment or account type involved. The page-specific control is that the complaint route depends on the issue type, evidence, response deadline and the remedy the customer is asking the firm to provide. Save the live source or provider wording used for section 2, because a small change in timing, eligibility, fee, account status or support route can change the practical result without changing the broad banking label.

Most other financial complaints use an eight-week response period

For most complaint types, the business has up to eight weeks to investigate and send a final response. Account closure complaints, service issues and other non-payment matters can fall under this broader timetable depending on the issue.

The final response should explain the outcome and how the customer can take the complaint further if still unhappy.

Read the final response carefully and compare it with the remedy requested. A partial refund or apology may not address consequential financial loss or a continuing account problem.

For 'Most other financial complaints use an eight-week response period', apply the rule to the exact amount, date, provider and payment or account type involved. The page-specific control is that the complaint route depends on the issue type, evidence, response deadline and the remedy the customer is asking the firm to provide. Save the live source or provider wording used for section 3, because a small change in timing, eligibility, fee, account status or support route can change the practical result without changing the broad banking label.

Escalate to the Financial Ombudsman within the permitted period

The Ombudsman is a free service for consumers. Its guidance says the final response normally tells the customer that they have six months from the date of that response to refer the matter to the Ombudsman.

Send the complaint chronology, final response, bank statements, receipts and other evidence rather than relying only on memory.

The Ombudsman considers the relevant law, regulations, codes and what is fair and reasonable in the circumstances. It is not simply another bank appeal desk.

For 'Escalate to the Financial Ombudsman within the permitted period', apply the rule to the exact amount, date, provider and payment or account type involved. The page-specific control is that the complaint route depends on the issue type, evidence, response deadline and the remedy the customer is asking the firm to provide. Save the live source or provider wording used for section 4, because a small change in timing, eligibility, fee, account status or support route can change the practical result without changing the broad banking label.

Quantify the impact and keep the requested remedy proportionate

List direct financial losses, extra charges, interest, missed-payment costs and reasonable practical effects. Evidence makes the loss easier to assess.

Ask for specific correction where possible: refund a charge, restore interest, correct an account record, reimburse a documented loss or explain a decision.

A precise remedy helps both the bank and the Ombudsman understand the dispute. Complaints are strongest when the requested outcome is connected directly to the documented failure.

For 'Quantify the impact and keep the requested remedy proportionate', apply the rule to the exact amount, date, provider and payment or account type involved. The page-specific control is that the complaint route depends on the issue type, evidence, response deadline and the remedy the customer is asking the firm to provide. Save the live source or provider wording used for section 5, because a small change in timing, eligibility, fee, account status or support route can change the practical result without changing the broad banking label.
