Martin Lewis on Debt Letters: What a Letter Before Action Means

Updated August 20266 min readEngland & Wales

Martin Lewis and the Money and Mental Health Policy Institute have repeatedly criticised the tone of aggressive debt collection letters. That does not mean formal debt letters are wrong. It means the wording, timing and process need to be clear, fair and proportionate.

A letter before action, also called a letter before claim, is the formal notice normally sent before court proceedings begin. It gives the recipient a final chance to pay, dispute the debt, ask for information or propose a repayment plan before the dispute escalates.

Key point: a proper letter before action is not just a threat. It should explain what is owed, why it is owed, what evidence supports the claim and what deadline applies.

What Martin Lewis Has Said About Debt Letters

Lewis has criticised debt collection systems that use intimidating wording or pile pressure onto people already struggling with money or mental health. His campaigns have focused on the harm caused by confusing, aggressive and legally frightening letters, particularly when the person receiving them does not know what to do next.

That criticism is aimed at bad process and bad wording. It is not a criticism of giving someone a fair written warning before taking court action. In fact, a properly written letter before action can reduce stress because it sets out the issue clearly and gives the other person a defined route to respond.

What a Letter Before Action Actually Does

A letter before action usually comes before a county court claim. For debt claims, the court system expects parties to exchange information and try to resolve the issue first. That means the letter should set out the amount claimed, how it was calculated and what the recipient should do if they agree or disagree.

PurposeGives formal notice before legal action and invites a response.
Used forUnpaid invoices, private debts, deposits, service disputes and similar civil claims.
DeadlineMust give a reasonable time to respond. Debt claims involving individuals have specific protocol requirements.
EvidenceShould explain the basis of the claim and refer to supporting documents.

If You Have Received One

Do not ignore it. Receiving a letter before action does not mean court action is guaranteed, but it does mean the sender is preparing to escalate if the issue is not resolved.

If You Need to Send One

If someone owes you money, a calm and properly structured letter before action is stronger than an angry message. It shows the court that you gave the other person a fair chance to resolve matters before issuing a claim.

The letter should state who owes the money, the amount claimed, the reason it is owed, the documents you rely on, what you want them to do, the deadline for response and what may happen next if there is no response.

The Takeaway

Martin Lewis's criticism is a useful warning: debt letters should not be designed to panic people. A good letter before action is firm but clear. It explains the claim, gives the other side room to respond and helps both parties avoid court if possible.
