Anything you say can be used in evidence. That sentence carries enormous weight. Here’s what an interview under caution really means and how to protect yourself.
What 'under caution' actually means
An interview under caution is not a casual conversation. The caution — ‘you do not have to say anything, but it may harm your defence if you do not mention when questioned something you later rely on in court, and anything you do say may be given in evidence’ — sets the legal framework for everything that follows.
The caution means two things: first, you are not obliged to answer questions; second, if you stay silent and later raise a defence at trial that you could have mentioned earlier, the court may draw an adverse inference. That second consequence is why silence is never a default — it is a strategic decision taken on advice.
The right to free legal advice
Before any interview under caution you are entitled to free, independent legal advice. This applies whether you are arrested or attending voluntarily, and it is not means-tested. A solicitor can speak with you in private, obtain disclosure from the police, and sit with you throughout the interview.
Many people decline advice because they feel they have ‘nothing to hide’. That is a mistake. The purpose of legal advice is not to help you conceal anything; it is to ensure you understand the allegation, the evidence, and the consequences of what you say before you say it.
Three interview strategies
There are broadly three approaches to an interview under caution, each chosen on advice. The first is to answer questions fully, where your account can be given clearly and the evidence supports it. The second is to give a prepared statement — a written account handed to the police — and then answer ‘no comment’ to further questions. The third is to answer ‘no comment’ throughout.
Each carries different consequences. A prepared statement can protect against adverse inferences while limiting what is put on record. A full no-comment interview may be right where the disclosure is weak or the case should not be charged at all. The decision is always evidence-led.
What can go wrong without advice
Without advice, people frequently say things that are later used against them — speculative explanations, admissions, or inconsistencies that are hard to retract. An interview is recorded; there is no taking it back. The most damaging evidence in many cases is the defendant’s own interview, given without advice.

Frequently asked questions
What does 'under caution' actually mean?
It means you are being questioned about an offence and anything you say may be given in evidence. The caution is a formal warning, not a trick, and it applies equally to voluntary interviews arranged by appointment as it does to interviews after arrest.
Is a 'no comment' interview always the best approach?
No. ‘No comment’ suits some cases — where disclosure is thin, or where the prosecution must prove everything. In others the adverse inference risk, or the need to put an innocent explanation on record early, makes answering the better course. The right answer depends on the evidence and your account.
Can I read the evidence before the interview?
You are entitled to sufficient disclosure to understand the general nature of the allegation. Your solicitor obtains this from the investigating officer, explains it to you in private, and uses it to decide the interview strategy. You are not entitled to the entire case file at that stage.
Can I change my mind and stop the interview?
You can ask to pause, and the interview can be suspended so you can speak to your solicitor again. You should not simply refuse to continue without advice — that itself can be commented on. Your solicitor will manage any break on your behalf.
What happens if I lie in interview?
A deliberate lie can support a prosecution case, damage your credibility if you later give a different account, and in some circumstances amount to a separate offence. If something you have already said is wrong, tell your solicitor immediately so it can be addressed properly.
