Jot down a few questions to make the most of your conversation.


Start with the firm that took your money

If you lost money through a bank, building society, lender, or investment firm, the first step is usually to complain to them directly. Explain what happened, what you believe went wrong, and how much money you want returned.

Keep your complaint clear and factual. Include dates, account numbers, copies of emails, screenshots, statements, and any adverts or documents you relied on.

Ask for a final response in writing. Firms usually have up to eight weeks to issue one, although some complaints may be resolved sooner.

Use the firm’s complaints process properly

Make the complaint through the official channel, such as online forms, email, post, or phone, depending on what the firm offers. If you speak to someone on the phone, follow up in writing so there is a record.

Say what outcome you want. That might be a refund, compensation for interest or fees, or reversal of an unauthorised transaction.

Keep copies of everything you send and receive. A simple timeline of events can help if the complaint later needs to be reviewed by a third party.

Escalate to the Financial Ombudsman Service

If the firm rejects your complaint or does not respond within eight weeks, you can usually take it to the Financial Ombudsman Service. This service is free for consumers and can look at many complaints about UK-regulated financial firms.

You normally need to complain to the firm first before the Ombudsman will consider it. There are time limits, so do not leave it too long after receiving the firm’s final response.

The Ombudsman will look at the evidence from both sides and decide what is fair and reasonable. If your complaint is upheld, the firm may have to repay money or make another remedy.

Watch for scams and unregulated schemes

If the money was lost in an investment scheme, crypto product, or overseas offer, check whether the business was authorised by the Financial Conduct Authority. Some schemes are scams and may not be covered by the usual complaints process.

Be cautious of recovery firms that ask for upfront fees or promise guaranteed refunds. A genuine claim should be based on evidence, proper regulation, and a realistic route to redress.

If you think you were mis-sold or pressured into an unsuitable investment, report it quickly. Acting early improves the chance of tracing money and preserving records.

Get extra help if needed

If the amount is large or the case is complex, consider getting help from a qualified solicitor or claims specialist with experience in financial disputes. Check costs carefully before agreeing to anything.

You can also ask Citizens Advice or a debt adviser for guidance if the loss has affected your finances. If fraud is involved, report it to Action Fraud and tell your bank immediately.

The key is to act quickly, stay organised, and use the official complaints route first. That gives you the best chance of recovering some or all of the money.

Frequently Asked Questions

Recover lost money complaint bank or investment scheme refers to a process for reporting financial losses to a bank, regulator, ombudsman, or other authority and seeking review, restitution, chargeback, reimbursement, or compensation where available.

Eligibility depends on the type of loss, the institution involved, the dates, the payment method, and local rules. Typically, people who lost money through bank errors, unauthorized transfers, scams, or misleading investment schemes may be able to complain.

Start by gathering evidence such as statements, transfers, emails, contracts, screenshots, and timelines. Then file a complaint with the bank or investment provider, and escalate to the relevant regulator, ombudsman, or consumer protection body if needed.

Useful evidence includes bank statements, transaction receipts, account numbers, correspondence, advertising materials, screenshots, call logs, identity details of the other party, and a clear timeline of events and losses.

The timeline varies by institution and jurisdiction. Simple banking complaints may resolve in days or weeks, while investment disputes or fraud investigations can take months or longer, especially if law enforcement is involved.

Yes, sometimes. Even if a payment was authorized, you may still have a claim if you were misled, pressured, promised false returns, or if the bank failed to follow required checks or safeguards.

Yes, it can. Recovery may be possible through bank fraud procedures, card chargebacks, wire recalls, fraud reports, regulator complaints, or civil claims, but success depends on the facts and how quickly action is taken.

Contact your bank immediately, freeze or secure accounts, change passwords, preserve evidence, and report the scam to the relevant financial institution and, where appropriate, the police or cybercrime reporting service.

Submit a formal written complaint to the bank's complaints team with dates, amounts, account details, what happened, what you want them to do, and supporting evidence. Keep copies and note reference numbers.

Write to the firm first with your complaint, then escalate to the financial ombudsman, regulator, or dispute resolution scheme if the firm does not resolve it. Include documents showing the advice, promises, losses, and your requested remedy.

Possible outcomes include reimbursement, partial refund, chargeback, account correction, compensation for losses, interest, formal apology, or a finding that no remedy is due.

Yes, deadlines often apply. Complaint windows, dispute limits, and limitation periods vary by country and claim type, so it is important to act as soon as possible after discovering the loss.

Not always. Many complaints can be started without a lawyer, especially with banks or ombudsman schemes. A lawyer may help if the case is complex, high value, cross-border, or likely to go to court.

Yes, if the payment was made by card and the transaction qualifies under card network rules. Chargebacks are time-limited and depend on the reason for dispute, evidence, and the card issuer's policy.

You can still file complaints with your bank, payment provider, regulator, ombudsman, or police. Recovery may be harder if the company is insolvent or untraceable, but preserved evidence still matters.

Use only regulated firms where possible, verify credentials independently, avoid upfront fees for guaranteed recovery, check reviews carefully, and never share full account access or recovery codes with unknown parties.

Keep statements, screenshots, emails, contracts, IDs used during onboarding, marketing materials, payment confirmations, complaint copies, response letters, and notes of phone calls with dates and names.

Sometimes, but it is usually more difficult. Recovery may depend on the exchange, wallet provider, payment rail used to fund the purchase, and whether a bank or card transaction can be disputed.

The best next step is to document everything, notify the relevant bank or investment provider in writing, and escalate through the formal complaint process without delay.
