The envelope lands on the doormat just after the rain starts. Inside is a final response from the bank: several pages of careful wording, a reference number, and a refusal to refund a payment you say you never authorised. The money has already gone. The complaints process has taken weeks, and the letter gives you only a short window to decide what happens next.
That is the moment many people discover that an ombudsman is not a general-purpose complaints desk. You cannot usually skip straight to it. First, you must give the financial firm or property business a proper opportunity to investigate the dispute through its own internal process. The ombudsman comes after that stage, not instead of it.
For a financial complaint in the UK, begin by contacting the firm in writing. Use the company’s complaints address or online form, but keep a copy of everything you send. Explain what happened in plain chronological order, say why you believe the firm is responsible, and describe the outcome you want. If a card payment is disputed, for example, identify the transaction, the date, the amount and the reason you say it should be reversed. Avoid turning the first letter into a life story. A clear timeline is easier for a complaints handler to test than a cloud of anger, even when the anger is entirely justified.
Attach the documents that support your account, such as statements, invoices, messages, photographs or earlier correspondence. Do not send originals unless the firm specifically requires them. A folder on your computer with filenames that include the date can save surprising amounts of time later. I have seen people spend longer hunting for the one decisive email than they spent writing the original complaint.
The Financial Ombudsman Service normally gives a financial firm eight weeks to issue its response. For complaints involving fraud and certain payment services, the response period is generally 15 days, subject to the rules that apply to the particular case. The firm may resolve the matter before then, make an offer, or send a final response rejecting the complaint. If the firm has not provided a response when the relevant period ends, you may be able to take the complaint to the ombudsman without waiting indefinitely.
The final response matters because it usually sets the next deadline. After receiving it, you normally have six months to refer the case to the financial ombudsman. That date can disappear into the small print, so mark it on your calendar as soon as the letter arrives. If you miss it, the ombudsman may refuse to investigate unless there is a valid reason for the delay.
Submitting the case is more than forwarding the firm’s rejection. You will need to explain what the dispute is about, what you have already done, and why the firm’s response does not settle the matter. Include the final response and the key evidence, but do not bury the central point beneath dozens of repeated attachments. A decision-maker needs to see the financial loss, the firm’s explanation and the gap between the two.
Be precise about the remedy you are seeking. That might be a refund, correction of a record, cancellation of a charge, compensation for a direct financial loss, or an explanation of what went wrong. The ombudsman can require a firm to put matters right within the limits of its powers, but it is not a court and does not operate as a punishment machine. A complaint is stronger when it shows the practical harm rather than simply demanding that the business be taught a lesson.
The compensation limit is not a reason to inflate a claim. For cases referred from 1 April 2026, the maximum enforceable award available through the financial ombudsman is £455,000. That figure does not mean every loss will be paid, nor does it remove the need to prove the connection between the firm’s mistake and the money claimed. If the loss is substantial or the dispute involves complex legal issues, professional advice may be sensible before you commit to a particular route.
Property complaints follow a similar pattern, but the clock and the paperwork are different. A tenant, buyer, landlord or seller must first use the estate agent’s or letting agent’s internal complaints procedure. Send the complaint to the business rather than treating a casual conversation with an individual negotiator as the formal first step. Ask the company to confirm that it has logged the complaint and tell you when its final response is due.
If there is no final response after eight weeks, the matter can generally be referred to the property ombudsman. The complaint must normally be submitted within 12 months of the property company’s final response. There is another time limit running alongside it: the original complaint should generally have been made within 12 months of the event, or of the point when you became aware of it.
Those dates can become messy in disputes over repairs, deposits, misdescribed properties or fees. A leak might begin on one date, become clearly serious months later and appear in several rounds of emails before anyone calls it a formal complaint. Write down the date of the event, the date you discovered its significance, the date you complained and the date of each response. If the business says that an informal message did not count as a complaint, you will at least have a clear record of what happened and when.
The property ombudsman will first consider whether the case is eligible. This assessment usually takes around 25 to 30 working days. That is not the same as receiving a final decision. Current waiting times for a decision are approximately three to six months, so a person facing an urgent housing problem should not assume that an ombudsman complaint will provide an immediate fix. Keep pressing the agent or landlord about practical safety or access issues while the complaint is being considered.
A strong property file often depends on details that seem trivial at the time: the photograph showing the damp patch before it was painted over, the inventory page with a missing signature, the invoice that does not match the fee described during the viewing. Save photographs with their original dates where possible. Keep messages in full rather than copying out only the sentence that supports your position. If a conversation happens by phone, send a short follow-up email recording what was agreed. It creates a trail without turning every exchange into a confrontation.
The ombudsman will look at fairness, the business’s obligations and the evidence available. That means you should address inconvenient facts instead of pretending they do not exist. If you delayed reporting a defect, explain why. If the firm offered a partial remedy, say whether you accepted it and what remained unresolved. Credibility is built through accuracy. A complaint that admits one weak point can be more persuasive than one that presents every detail as unquestionable.
The process can feel strangely quiet. There may be long gaps between updates, followed by a request for one document that you thought had already been sent. Respond by the stated deadline and keep copies of your submissions. If you need more time, ask before the deadline passes and explain why. Do not send daily messages simply to prove that you are still angry; send a focused update when there is a new fact, a missed deadline or a document the investigator needs.
An ombudsman complaint works best when it reads like a reliable account of a problem rather than a closing argument in a courtroom. Set out what happened, show the evidence, identify the firm’s response and explain the remedy that would put the situation right. The worn carpet, the unexplained charge or the payment missing from the account may be the detail that makes the dispute real, but the dates and documents are what allow someone outside the dispute to act on it.
