Financial Ombudsman evidence pack: what to include

A good Financial Ombudsman complaint is not a box of every document you own. It is a short, dated account of what happened, the evidence that proves each important step and a clear explanation of what you want the bank to put right.

Build the timeline before you collect attachments

Write the story as dates and events, not as a long narrative. Record when the payment was made, when you first contacted the bank, what the bank said, when you supplied evidence and when the final response arrived. If the dispute is about a transfer, include the amount, recipient, payment reference and the status the app showed. If it is about a fee or account closure, include the exact notice or statement entry.

A useful timeline might fit on half a page: ‘4 May - £1,850 transfer sent; 4 May - recipient says nothing arrived; 5 May - bank case 12345 opened; 12 May - bank says payment completed; 20 May - formal complaint; 3 June - final response’. That structure lets a case handler see the sequence without hunting through screenshots.

Practical checkpoint for building an evidence pack for the Financial Ombudsman: establish the starting position before you change anything. Use a complaint with six calls, two disputed payments and a final response letter as a worked example and write down one-page chronology, final response, statements, relevant messages, quantified loss and requested remedy. That turns 'Build the timeline before you collect attachments' into a testable sequence rather than a vague problem.

Use evidence that proves a point, not evidence that merely exists

Attach the final response, relevant statements, payment confirmations, screenshots, correspondence and any contract or tariff wording that matters. Label each item so the reader knows why it is there. Ten clearly named files are usually more useful than 80 unsorted screenshots. Never include passwords, one-time passcodes or full card security details.

If you are claiming a direct financial loss, show the link. For example, if a bank error caused a £35 late-payment charge on another account, provide the bank error, the £35 charge and the date relationship. If you are asking for compensation for distress or inconvenience, describe the concrete impact - repeated branch visits, inability to pay a bill, time without access - rather than inventing an arbitrary cash figure.

Run the numbers or sequence on paper before repeating the action. In the example of a complaint with six calls, two disputed payments and a final response letter, separate the amount, date, channel and decision point, then mark which part is confirmed and which part is still an assumption. For 'Use evidence that proves a point, not evidence that merely exists', the useful question is not simply whether something can work, but what result you should see next and how long you are prepared to wait before changing route.

Ask the bank the questions the Ombudsman will later need answered

Before escalation, ask the bank to state its position clearly. Which term, rule or transaction status is it relying on? What date did it consider the complaint resolved? If a payment was blocked, was the block a fraud review, a technical failure or a compliance restriction? If a fee was applied, which tariff line created it? A precise answer can resolve the matter or expose the real point of disagreement.

Also ask for the complaint reference and confirm whether the message you received is the formal final response. This matters because the final response normally explains your right to go to the Financial Ombudsman Service and starts the usual six-month referral window.

Use a controlled process for 'Ask the bank the questions the Ombudsman will later need answered'. Gather one-page chronology, final response, statements, relevant messages, quantified loss and requested remedy, take one deliberate action, and record the result before trying a second route. Do not send hundreds of pages without showing which document proves which point. If the first route clearly cannot complete the job, index the evidence by date and issue so another person can understand the case without reconstructing it from scratch rather than improvising with an unverified workaround.

Match the complaint deadline to the type of problem

The Financial Ombudsman Service says firms generally have up to eight weeks to deal with most complaints. Complaints about payment services, fraud, scams and electronic money normally use a 15-business-day response period, with limited scope for a later response up to 35 business days. Do not wait for eight weeks if your complaint is in the shorter category and the firm has already missed the applicable deadline.

Once a valid final response arrives, the usual referral deadline is six months. Keep the response email or letter because the Ombudsman may ask for it. If you are close to a deadline, submit the complaint with the essential evidence first rather than delaying for a perfectly formatted bundle.

Build a failure plan before the deadline matters. For building an evidence pack for the Financial Ombudsman, decide what you will do if the normal route fails at the worst reasonable moment: a bill is due, a payment is time-critical, a phone is unavailable or verification will not complete. Keep enough time and money outside the process to recover. Under 'Match the complaint deadline to the type of problem', note the exact error or refusal wording because that is usually more useful to support than a general statement that it did not work.

Make the remedy specific and proportionate

Say what would put the matter right. That could be refunding a fee, restoring money, correcting a credit-file entry, paying documented consequential loss, reconsidering a claim or explaining an account decision. A remedy such as ‘refund £240 wrongly charged and reimburse the £25 late fee it caused’ is much easier to assess than ‘compensate me fairly’.

Separate money you can prove from inconvenience you want the Ombudsman to consider. This helps the case handler see what is arithmetic and what requires a judgment about fairness. It also makes it harder for the core issue to disappear inside an emotional but unfocused complaint.

Treat evidence as part of the solution, not paperwork added afterwards. For 'Make the remedy specific and proportionate', keep one-page chronology, final response, statements, relevant messages, quantified loss and requested remedy in one dated folder and write a two-line chronology of each contact. Do not send hundreds of pages without showing which document proves which point, and use only a channel you reached independently when security or fraud is involved.

Send a pack another person can understand in ten minutes

Before submitting, pretend the reader knows nothing about your case. Can they identify the product, disputed event, amount, key dates, bank’s final position and requested remedy without opening every attachment? If not, simplify the front page. The strongest pack is an index to the evidence, not a replacement for it.

Keep the originals after submission. If the Ombudsman asks for another statement period, call recording or bank document, add it as a new item rather than rewriting the whole history. A stable timeline with numbered evidence is easier to update and much easier to challenge if the bank later changes its explanation.

Finish with a decision rule for building an evidence pack for the Financial Ombudsman. In the worked example of a complaint with six calls, two disputed payments and a final response letter, the safer next step is the one that preserves evidence and keeps essential money or account access recoverable. If the provider cannot explain the next step clearly, index the evidence by date and issue so another person can understand the case without reconstructing it from scratch and keep the case reference until the outcome is reconciled.
