Debt Validation Letter UK: What to Ask For Instead

The letter says you owe a sum you do not recognise, and the deadline is in the next paragraph.

Check the date before you write anything

Citizens Advice says that for most debts the time limit is 6 years from your last written contact or payment, and that writing or paying can look like accepting the debt and restart it (Citizens Advice). If there is any chance the debt is older than that, stop and use the checker above, then speak to an adviser. Phoning to check details is the safer route the page describes.

What you can ask for

• A copy of the credit agreement, if the debt is regulated.
• A statement of account showing what is owed and how it built up.
• Who owns the debt now, and the original creditor’s name and account number.
• The date of your last payment on the account.

For regulated debts, National Debtline gives the fee as £1 for the agreement and statement under sections 77, 78 and 79, with 12 working days to reply (National Debtline). Only use this route if the debt is not old.

A short letter, in our own words

Send it by a method you can prove, keep a copy, and do not admit the debt is yours in the wording. We have not had this wording checked by a solicitor, so treat it as a starting point.

When the debt has been sold

StepChange says your original creditor needs to tell you when it sells your debt, and the new owner should write to you naming itself and the original creditor (StepChange). If you are unsure the letter is real, call the original creditor first.

What readers often ask

Is a debt validation letter a thing in the UK?

Not under that name. The term comes from the US. The closest UK tool is a request for a copy of your credit agreement and a statement of account under the Consumer Credit Act 1974, which National Debtline explains (National Debtline).

What does it cost and how long do they have?

National Debtline says the fee is £1 for a copy of the agreement and statement of account under sections 77, 78 and 79, that a statement of account under section 77b is free, and that creditors normally have 12 working days to respond (National Debtline).

What if they do not reply?

National Debtline says the creditor cannot take further court action to enforce the agreement until it sends the documents, and cannot get a judgment in the meantime. The debt still exists, and it can still add interest and charges, pass the debt to a collector or sell it (National Debtline).

Could writing restart the clock on an old debt?

Yes, it can. Citizens Advice says that if the time limit may have ended or will end soon, you should get advice before responding, and not write, including by text, email or chat, or pay anything, because writing or paying can look like accepting the debt and may restart the time limit for another 6 years. You can phone to check details. That page was last reviewed in February 2019, so check current rules (Citizens Advice). Use our statute barred checker first.

Does this work for buy now pay later or other unregulated debts?

Not necessarily. National Debtline says the Consumer Credit Act applies only to regulated debts and that some agreements, such as some credit union and buy now pay later debts, are unregulated or exempt (National Debtline). You can still ask for a statement of what is owed and how it was calculated.

The debt was sold to a collector. Who has to tell me?

StepChange says your original creditor needs to tell you when it sells your debt, and the new owner should write naming itself, naming the original creditor and usually giving the original account number. If you doubt the letter is genuine, call the original creditor (StepChange).
