How to Complain About a Bank or Debt Collector UK
How to Complain About a Bank or Debt Collector in the UK
Complaining is not being difficult. It is using a process that already exists.
If a bank, lender or debt collection agency has treated you unfairly, you are allowed to raise it. You do not need legal training, and you do not need to sound angry.
A strong complaint is usually the boring one. It is clear, factual, dated and backed by evidence. It says what happened, why it was unfair and what you want the business to do about it.
This guide explains how to complain to the business first, what to include, how long they have to respond, what a final response letter is, and when the Financial Ombudsman Service may be able to look at your complaint.
This is general information, not personal financial advice or regulated debt advice.
Quick answer: how do you complain about a bank or debt collector?
Complain to the business first, in writing where you can. Explain what happened, include dates and evidence, say why you think the treatment was unfair and say what you want them to do.
The Financial Ombudsman Service says a business has 8 weeks to respond to your complaint.
If you are unhappy with the response, you usually have to bring your complaint to the Financial Ombudsman within six months of the date of the business’s final response. There is also a wider limit: usually within six years of the event you are complaining about, or, if later, within three years of when you realised, or should reasonably have realised, there was a problem.
Bringing a complaint to the Financial Ombudsman does not cost you anything.

The aim is to work out exactly what you are complaining about before you start writing.
When might a complaint be worth making?
You may want to complain if:
- you were pressured to pay more than you could afford;
- you were pushed to borrow more, or to sell something, to clear the debt;
- contact felt excessive, or happened at unreasonable times;
- you disputed the debt and they carried on chasing anyway;
- they discussed your debt with someone else;
- they ignored health, mental health or vulnerability information you gave them;
- they gave unclear, misleading or contradictory information;
- charges or interest were added that you do not understand;
- paperwork looked official when it was not;
- they implied court action or enforcement that was not actually happening.
Several of those points are not just unfair. They sit against the FCA’s conduct rules for debt collection. For example, a firm must not pressurise a customer to pay a debt in one single or very few repayments, within an unreasonably short period of time, or by selling their property, borrowing money or increasing existing borrowing.
The FCA rules also say a firm must suspend any steps it takes, or its agent takes, in the recovery of a debt where the customer disputes the debt on valid grounds or what may be valid grounds.
Not sure what to put in writing?
If you have a letter, a final response or a complaint you are struggling to word, the Letter Review & Action Plan can help you understand what to check and prepare a written complaint in your own name.
The best complaint is not the loudest one. It is the one with dates, evidence and a clear ask at the end.
The Real Debt Guy
What should your complaint include?
Keep it organised. A business cannot investigate what it cannot follow.
Include:
- your name, address and the account or reference number;
- the name of the business you are complaining about;
- the date you are writing;
- a short summary of what happened, in order;
- key dates of calls, letters, emails and messages;
- copies of your evidence, not the originals;
- what you believe was unfair or wrong;
- how it affected you, including any health impact;
- what you want them to do to put it right;
- how and when you want them to contact you.
Ask them to confirm they have received it, and keep a copy of everything you send.
If you need contact in a particular format, or you need them to stop phoning and write instead, say that clearly in the complaint.
Step 1: complain to the business first
The Financial Ombudsman Service normally expects the business to have had the chance to look at your complaint before it gets involved.
Send it using a method you can prove. Email is usually fine if you keep the sent copy. If you post it, consider recorded delivery for anything important, and keep the proof of postage.
Address it to the complaints team if the business names one. If not, send it to the main contact address and title it clearly as a complaint.
Do not bury the complaint inside a long payment discussion. Keep the complaint separate so it is obvious what you are asking them to investigate.
Important: watch the complaint deadlines
The Financial Ombudsman Service says a business has 8 weeks to respond to your complaint.
If you are unhappy with the answer, you usually have to bring the complaint to the Ombudsman within six months of the date of the business’s final response.
There is also a wider time limit. You usually have to bring a complaint within six years of the event you are complaining about, or, if later, within three years of when you realised, or should reasonably have realised, there was a problem.
Do not leave this until the last week. If a deadline passes, it can be much harder to get the complaint looked at.
What is a final response letter?
A final response letter tells you the business has finished looking at your complaint.
It should explain whether they are upholding your complaint, what they will do about it, and how to take the complaint further if you disagree.
Read it slowly and check:
- has it answered every point you raised, or only the easy ones;
- has it dealt with the evidence you sent;
- does it explain what happens next;
- does it give you the Financial Ombudsman referral information;
- what is the date on the letter, because that date matters for the six-month window.
Do not throw it away. If you escalate, you will normally need it.
Step 2: when can the Financial Ombudsman look at it?
The Financial Ombudsman Service may be able to look at your complaint once you have had a final response you are unhappy with, or once the business has had the time it is allowed and still has not resolved it.
You will need to explain what happened and send the relevant evidence, including your complaint and any response.
The Ombudsman is not there to punish a business for every mistake. It looks at what it thinks is fair and reasonable in the circumstances.
Bringing a complaint to the Financial Ombudsman does not cost you anything.
Where does the Consumer Duty fit in?
The FCA’s Consumer Duty sets a higher standard for how firms treat retail customers. In broad terms, firms have to act to deliver good outcomes for retail customers, including supporting customers to pursue their financial objectives and making sure communications help customers understand what is happening.
You do not need to quote regulations to make a complaint. But it can help to frame your points around outcomes and understanding rather than emotion alone. For example:
- “The letters did not make it clear what would happen next.”
- “I explained my situation twice and the same demand was repeated.”
- “I asked for the debt to be checked and collection continued anyway.”
That kind of wording keeps the focus on what the business did, and what a reasonable customer would have expected.
Were you pushed into payments you could not afford?
If part of your complaint is about affordability, work through the TRDG Budget Planner first. It can help you show your income, priority bills, essential costs and what is genuinely left, in your own figures.
Complaining when your mental health is involved
If debt contact is affecting your mental health, say so in the complaint. Do not leave it in the background. Explain:
- what you told them, and when;
- who you told;
- what you asked them to do differently;
- what happened afterwards.
The FCA rules also expect firms to treat customers in difficulty with forbearance and due consideration, and to point people towards free debt help from not-for-profit debt advice bodies.
Separately, if you live in England or Wales, Breathing Space is a scheme that can give temporary protection from creditors while you get debt help. GOV.UK says you can get temporary protection for up to 60 days, and if you are getting mental health crisis treatment, protection lasts for the length of your treatment plus another 30 days. You apply through a debt adviser, not directly.
What if the behaviour is more than just poor service?
Some conduct goes beyond a service failure. Citizens Advice lists examples of behaviour that could count as harassment by a creditor, including contacting you several times a day or late at night, using more than one debt collector at a time, using paperwork that looks official when it is not, pressuring you to sell your home or take out more credit, telling other people about your debt, or giving the impression that court action has been taken when it has not.
If any of that is in your situation, keep a dated log of every contact. A log turns a feeling into evidence.
You can still complain to the business first, and escalate to the Financial Ombudsman if you are unhappy with the answer.
What outcome should you ask for?
A complaint is much stronger when it ends with a specific ask. Vague complaints get vague answers.
Depending on the situation, you might ask the business to:
- correct the account balance or remove charges you dispute;
- put the account on hold while they check the debt;
- confirm in writing what they hold, and who they say owns the debt;
- change the way they contact you;
- correct information reported to your credit file;
- explain a decision properly in plain English;
- confirm what they will do differently.
Say what you want, in a short numbered list, at the end of the complaint. Then keep a diary date for eight weeks after you send it.
Had a final response you do not agree with?
If you have a final response letter and you are unsure whether it answers your points, TRDG support options can help you get organised before you decide what to do next.
Your complaint checklist
Use this checklist:
- Decide exactly what you are complaining about.
