Should You Call or Write to a Debt Collector in the UK?

When a debt collector contacts you, the method you use to reply matters more than most people realise.

A phone call feels faster. You get answers straight away, and it can seem like the quickest way to stop the letters or messages coming through. But a call is not always the best place to be making careful money decisions, and once the call ends, there is often no clear record of what was actually agreed.

This article explains why replying in writing usually protects you better, when a call is still fine to make, and what to check before you agree to anything.

This is general information about how UK debt collection works. It is not personal financial advice or regulated debt advice.

Useful next steps before you reply

Before you pick up the phone or draft a reply, put the wider picture in front of yourself:

• If the account is old, read What Is Statute Barred Debt and How Do I Know If Mine Qualifies? before making any admission.
• If a settlement has been mentioned, read Partial Settlements UK: What to Check Before You Say Yes.
• If you are not sure what you can realistically afford each month, use the TRDG Budget Planner first.

The aim is to reply on your own terms, not on the collector's timing.

Why calls feel easier and why that is the risk

Phone calls feel quick. You get an answer straight away, you do not have to write anything, and it can feel like the fastest way to stop the letters coming through.

That is why most debt collection letters push you towards calling. A number in bold, a "call us today to discuss your options" line, sometimes a QR code.

The problem is that a call is not always the best environment for making careful money decisions. If you are anxious or embarrassed, you might agree to something simply to end the conversation. You might also be asked questions about your income, spending, family situation, bank details, or employment before you have had time to think about what is actually needed.

That is why the method of communication matters. It is not just about being polite or cooperative. It is about protecting yourself.

Why writing usually protects you better

Writing changes the balance of the conversation in three ways.

1. You have time to think. A letter gives you the space to check the balance, look at your budget, check the age of the debt, and read what the rules actually say before you reply. A call takes that away.

2. You keep a record. Every letter or email is a copy you can go back to. If a firm later says something different, the record is on your side. Phone notes are notoriously incomplete, and firms rarely share their own call recordings without a formal request.

3. The firm is on the record too. When something is written, it is easier to hold a firm to it. That is useful if you later complain to the firm, and then take it to the Financial Ombudsman Service.

What should you put in writing?

Anything that matters. In particular:

• Any payment offer.
• Any request for proof of the debt.
• Any complaint about how you have been treated.
• Any dispute about the amount owed.
• Any request to change or reduce contact.
• Any affordability information you choose to provide.
• Any settlement offer.
• Any confirmation that a payment will be accepted as full and final settlement.

If you do speak by phone, ask for written confirmation afterwards. If the firm will not confirm it in writing, be careful about relying on it.

A worked example: how a call can go wrong

Faye is renting on her own in Greater Manchester. Her wages cover the basics, but not comfortably. Rent, food, energy bills, and credit payments are all competing for the same money.

One of her accounts has been passed to a debt collector. She gets home from work, sees the letter, panics, and calls the number straight away.

The person on the phone sounds helpful, but the call quickly turns into questions about her income, her spending, and what she can pay today. Faye feels under pressure. She wants the stress to stop, so she agrees to a payment that sounds manageable in the moment.

Then rent comes out. Food costs more than expected. Her energy bill lands. Suddenly, the payment she agreed to does not work.

That is the risk. Phone calls can create quick agreements, but quick agreements are not always affordable agreements.

The evidence problem with phone calls

Even if the call goes well, there is a second problem: what happens if something goes wrong later?

If a firm promises on the phone that a partial payment closes the account, or that letters will stop, or that a marker will be removed from your credit file, that promise only exists in the call. Your note might say one thing. Their internal note might say another.

Written records solve that. An email, a letter, or a chat transcript can be produced later if the firm changes its position, if the account is sold on to a different firm, or if you need to complain to the Financial Ombudsman Service.

If you must have a call, take these three steps every time:

• Ask for the person's name and the date and time.
• Write down what was discussed as soon as the call ends.
• Ask them to confirm anything important by email or letter before you rely on it.

Can a debt collector pressure you to pay more than you can afford?

The FCA is clear on this. CONC 7.3 says a firm must treat customers in arrears or default with forbearance and due consideration. In plain English: firms are not allowed to press for repayment at a level a customer cannot reasonably afford, and they must consider your wider situation.

That does not always match the tone of a live call. If a call is putting you under pressure to commit today, you are entitled to stop the call and ask for the request in writing. A firm that refuses to put things in writing, or that pushes you to decide inside a single call, is not treating you fairly under those rules, and that is a valid ground for complaint.

When it is okay to call a debt collector

Calling is not always wrong. Sometimes a call is the fastest way to deal with basic admin, such as:

• Checking whether a firm has received your letter.
• Asking for the correct email address or postal address for correspondence.
• Requesting a reference number.
• Confirming where to send a document.

The key is to avoid making important decisions on the call. If you do call, keep it simple:

• Ask for the person's name.
• Note the date and time.
• Write down what was discussed.
• Do not agree to a payment you have not budgeted for.
• Do not make a settlement payment without written confirmation.
• Ask them to confirm anything important by email or letter.

You can also say, plainly: "I would prefer to deal with this in writing. Please send your response by email or letter." That is a reasonable request, and firms are expected to respect it.

What if the debt collector will not stop calling?

You can ask, in writing, for contact to be by letter or email only. FCA rules in CONC 7.9 say firms must respect a customer's reasonable request about the method and timing of contact, and must not put the customer under undue pressure.

If a firm ignores that request and keeps calling repeatedly, at unreasonable times, or at your workplace, that is a valid reason to complain in writing to the firm first, and then, if they do not resolve it within eight weeks, to the Financial Ombudsman Service.

What if you do not recognise the debt?

Do not agree to it. Ask for proof of the debt in writing before doing anything else.

FCA rules in CONC 7.14 say firms must suspend recovery activity where a customer disputes a debt on grounds that are, or may be, valid, and should take reasonable steps to investigate the dispute.

In plain English: if you tell a firm, in writing, that you do not recognise the debt, that you are not the correct borrower, or that the amount is wrong, they should pause collection while they investigate. Valid grounds can include that the person being pursued is not the correct borrower, that the debt does not exist, or that the amount being pursued is incorrect.

If the firm is not the original lender or does not own the debt, they should also be able to deal properly with the dispute rather than pushing you to pay while it is unresolved.

What if the debt is old?

Do not admit or pay anything until you have checked the age of the debt.

Under the Limitation Act 1980, most unsecured credit debts in England, Wales and Northern Ireland can become statute barred after six years without a payment or a written acknowledgement. Scotland uses a prescriptive period of five years. Once a debt is statute barred, it still exists, but a court claim can be defended on limitation grounds.

A payment or a written admission can restart that clock on an account that has not yet become statute barred, under section 29(5) of the Limitation Act 1980. That is why an old-debt call is one of the highest-risk conversations to have without checking first.

A short call-or-write checklist

Before you decide how to reply, run through this list:

• Is the letter or call asking you to make a decision today?
• Do you know for certain the debt is yours and the balance is right?
• Do you know the age of the debt?
• Have you checked what you can genuinely afford each month?
• Would a written reply give you time to check the above before committing?
• If you must speak by phone, do you have a way to record the person's name, date, and what was discussed?
• Have you asked for anything important to be confirmed in writing before you rely on it?

If any answer is no, a written reply is almost always the safer route.
