A police caution is not a warning, and it is not a let-off. It is a formal admission that you committed a criminal offence, recorded against your name, disclosed on employment checks, and reportable to a professional regulator. It is offered in a custody suite or an interview room, before anybody has been charged, and very often to somebody who has no solicitor with them. The offer usually arrives at the worst possible moment, framed as the quick way out of a long day. Accepting it takes about a minute. Undoing it takes years, and frequently cannot be done at all.
The phrase does two jobs in English law, which is the first thing to clear up.
There is the caution that is read to you, the words beginning "you do not have to say anything", which is a warning given before questioning. That is a procedural safeguard, not a penalty, and we deal with it separately in our guide to the voluntary interview under caution.
Then there is the caution as a disposal: a way of concluding a criminal allegation without going to court. That is what this page is about, and it is what almost everybody means when they ask whether they should accept a caution.
For adults there are currently two.
A simple caution is a formal recorded admission with nothing attached to it. There is no penalty, no condition and no court appearance. The matter concludes on the day, and the record follows. It is often described as a formal warning, which is where the misunderstanding starts, since a warning implies nothing was written down.
A conditional caution is given under Part 3 of the Criminal Justice Act 2003 and carries conditions. Those conditions may be rehabilitative, aimed at the offending behaviour itself, such as attending a course, reparative, such as compensating or apologising or taking part in restorative justice, or punitive, such as an appropriate fine. Failure to comply can result in prosecution for the original offence, which means a conditional caution keeps the case alive in a way a simple caution does not. Decisions on conditional cautions can involve the Crown Prosecution Service rather than the police alone, and the conditions attached are not a negotiation the person is usually invited into.
Both require the same thing from you: an admission of guilt to the offence alleged.
This page is about adults. A person under 18 may receive a youth caution or a youth conditional caution, which run on their own rules, ordinarily involve a youth offending team, and are disclosed differently. A youth conditional caution also addresses offending behaviour through conditions in a way the adult simple caution does not. If the person concerned is under 18, the framework below is not the one that applies to them, and the legal advice they need is different.
A conditional caution given to a relevant foreign offender can carry foreign offender conditions, which require the person to leave the United Kingdom and not to return for a period. Those conditions can involve surrendering a valid national travel document and dealings with the immigration office responsible for the case.
This matters more than its rarity suggests. A caution accepted to end a minor matter quickly can carry immigration consequences that nobody in the room raised, and for somebody living and working here on a visa, those consequences are the whole case.
A police caution is not available at the discretion of whoever happens to be in the room. The guidance governing simple cautions for adult offenders sets four conditions, and all four must be satisfied.
Read that first condition again, because it is the one that matters most and the one least often explained. A caution is not a middle ground between guilt and innocence. It is a disposal available only where the case is strong enough to prosecute, and following an admission to the offending.
Section 17 of the Criminal Justice and Courts Act 2015 limits when a simple caution can be given at all.
For an indictable only offence, a police officer may not give a caution except in exceptional circumstances relating to the person or the offence, and with the consent of the Director of Public Prosecutions. For an either way offence specified by order, not except in exceptional circumstances relating to the person or the offence. For a summary or unspecified either way offence where the person has been convicted of or cautioned for a similar offence in the previous two years, again not except in exceptional circumstances.
The practical effect is that a police caution is designed for minor offences, and one offered for a serious matter should be a rarity requiring authority from outside the police station. Where a caution is offered in a case that looks more serious than the disposal suggests, that is worth understanding from an evidential viewpoint, rather than accepting gratefully.
Part 6 of the Police, Crime, Sentencing and Courts Act 2022 replaces the present system entirely. Sections 98 to 121 create two new disposals, the diversionary caution and the community caution, and section 118 abolishes every other adult caution, removing Part 3 of the Criminal Justice Act 2003 along with it. The same section repeals the on-the-spot penalty provisions in the Criminal Justice and Police Act 2001, so the penalty notice for disorder goes with them.
None of it is in force. Section 98 and section 118 each carry the note "not in force at Royal Assent, see s. 208(1)". Section 17 of the Criminal Justice and Courts Act 2015 is shown on the statute as omitted by the 2022 Act, which is a pending amendment rather than one that has taken effect. Royal Assent was in April 2022.
We checked this against the sections themselves in September 2026, rather than against a factsheet, and it is worth saying plainly what it means. A person cautioned today is cautioned under the old framework. Commentary describing the two-tier system as the current law is describing something that has not happened yet. If you are reading about diversionary and community cautions and wondering why nobody at the police station mentioned them, that is why.
This is where most of the damage is done, and it is done by a misunderstanding that the wording of the disposal actively encourages.
A caution is not a conviction. That is true, and it is the sentence people remember. What it does not mean is that nothing has been recorded. A caution is entered on the Police National Computer and forms part of your criminal record. It is capable of being disclosed, of being declared, and of being used against you later in any enhanced DBS check.
There are three levels of check, and a police caution behaves differently on each.
So the honest answer to how long a police caution lasts is that it depends entirely on what the caution was for, and for a category of serious offences the answer is permanently.
A caution can be put before a court in later proceedings as evidence of previous misconduct under the bad character provisions of the Criminal Justice Act 2003. Somebody who accepts a caution to make one allegation go away can find it introduced against them in a trial on a different allegation years later, as evidence of propensity, which is designed to prove a 'pattern of behaviour'.
For most people a caution is an administrative inconvenience. For a regulated professional it is frequently the end of the matter that actually counts.
A caution is disclosable to the Solicitors Regulation Authority, the General Medical Council, the Teaching Regulation Agency, the Nursing and Midwifery Council and their equivalents. It can found a referral on its own, without any conviction and without any trial, and the regulator then decides the case on the balance of probabilities rather than the criminal standard. That is the structural problem we set out for doctors facing a GMC investigation alongside a criminal case and for teachers referred to the TRA, and it applies across every regulated profession, which is why we treat parallel exposure as one problem rather than two.
There is a particular cruelty in the sequence. Somebody accepts a caution precisely to avoid a court hearing, the publicity and the risk of a conviction. In doing so they hand their regulator a signed admission of the very conduct alleged, which is stronger material than anything the regulator would have obtained from a contested case that ended in acquittal.
A referral to the Disclosure and Barring Service may follow separately, and a barring decision reaches beyond a single profession to any work with children or vulnerable adults.
Accepting a caution can also affect travel. It is an admission of a criminal offence, and it falls to be disclosed on a United States visa waiver application among others.
Consider the circumstances in which this choice is put to someone.
They have usually been at a police station for hours. They have been interviewed by a police officer, perhaps arrested, quite possibly detained overnight. They are tired, frightened and want to go home. They are told, often in entirely good faith, that a caution will conclude the matter today, that there will be no attending court and no criminal conviction, and that the alternative is a charge. Nobody in the room is required to explain the potential consequences of the record in four years' time, or to suggest they take legal advice before answering.
Most people in that position say yes. It is a rational response to the information they have been given, and the information they have been given is incomplete rather than wrong.
The question they have not been asked is whether the case should be resolved at all. A caution requires enough evidence for a realistic prospect of conviction and a clear and reliable admission. Where the evidence does not reach that standard, the proper outcome is not a lesser disposal. It is no further action. A caution offered where the evidence is thin is the convenient disposal rather than the correct one, and accepting it forecloses the argument that the case should never have gone anywhere.
This is exactly the territory where the decision about what to say, and when determines everything that follows, and it is why we treat the preparation before an interview as the substantive stage rather than the formality.
Declining a caution is not defiance, and it does not annoy the system into punishing you. It is a tactical decision with a range of outcomes.
If you refuse, the police may charge you, refer the file to the CPS for a charging decision, take no further action, or leave the matter outstanding while they consider it. You may be released under investigation or on bail in the meantime, which is its own uncertainty and carries no timetable.
The calculation is not "caution versus court". It is: is there enough evidence here to prosecute at all, what does the record cost me over the next decade, and is there a submission capable of producing no further action instead. Answering that needs legal advice from somebody who has seen how the police and the CPS assess these files from the other side. Where the case genuinely is strong and the matter is one of the less serious offences, it can be sensible to accept a caution, and we will say so rather than manufacture a fight.
There is no formal right of appeal against a caution. That absence surprises people, and it is the strongest practical argument for taking legal advice before rather than after.
Two routes exist.
Both are difficult, both are slower and more expensive than declining the caution would have been, and neither is a substitute for the conversation that should have happened in the custody suite.
We act at the point the decision is being made, which is the only point at which it is cheap to influence. Legal advice given before somebody agrees to accept a caution is worth more than any amount of it afterwards.
In practice that means attending the police station or the voluntary interview so that the caution is not offered into a vacuum, so that a police officer's account of the consequences is not the only one in the room, testing whether the evidential standard for any disposal is actually met, and where it is not, making written representations for no further action rather than accepting a record. That is the substance of our pre-charge representation practice, and the reasoning behind why we treat the pre-charge stage as decisive. Where a charge has already been brought, the same analysis is put to the prosecution as the basis for a review of the charging decision and discontinuance, rather than waiting to win at trial. This forms part of our wider criminal defence work.
Where a caution has already been accepted, we advise on deletion and judicial review, and on the separate regulatory exposure that usually follows it.
We do not wait to see what happens. A caution is one of the few moments in a criminal case where the outcome is decided in a single conversation, and the person being asked to decide is almost always the least informed party in the room.
We offer confidential consultations, in person at our London offices or remotely by secure call. Initial enquiries are handled discreetly and quickly.
If the police have offered you a caution, or told you that one is available if you admit the offence, take legal advice before you accept a caution. That decision is far harder to undo than to get right.
Yes, although it is not a conviction. A caution is recorded on the Police National Computer and forms part of your criminal record. It can be disclosed on employment checks, must be declared to a professional regulator, and can be used in later proceedings as evidence of previous misconduct.
It stays on the Police National Computer indefinitely. What changes is disclosure. A simple caution given to an adult is filtered from standard and enhanced DBS certificates after six years, provided the offence is not on the specified list. Offences on that list are never filtered and are disclosed for life.
Not on a basic check, because a caution is spent immediately under the Rehabilitation of Offenders Act 1974. It is disclosed on standard and enhanced checks, subject to the six-year filtering rule and the specified-offence exception.
A simple caution is a recorded admission with nothing attached. A conditional caution, given under Part 3 of the Criminal Justice Act 2003, carries conditions which may be rehabilitative, reparative or punitive, and failure to comply can result in prosecution for the original offence.
Yes. A caution cannot be given without your agreement. Refusing does not conclude the matter: the police may charge you, refer the file to the CPS, take no further action, or leave it outstanding. Whether refusing is the right decision depends on the strength of the evidence and on what the record would cost you.
Yes. A clear and reliable admission is a precondition. Without one, a caution should not be offered, and a caution administered without a valid admission is a ground for applying to have it deleted.
There is no right of appeal. A record deletion application can be made to the police force through the process administered by ACRO, on grounds including that the caution was unlawful or given without a valid admission or informed consent. Judicial review of the decision is also possible and must be brought promptly, within three months.
In almost all cases yes. A caution is disclosable to the SRA, the GMC, the TRA, the NMC and equivalent bodies, and it can found a referral on its own. The regulator decides on the balance of probabilities, so a caution is powerful material in its hands. You can contact our team directly for a confidential discussion.
It may. A caution is an admission of a criminal offence and falls to be disclosed on a visa waiver application. Anyone travelling for work should take advice before assuming a caution is invisible outside this country.
No, and the five-year figure is one of the most common misunderstandings on this subject. A police caution stays on the Police National Computer indefinitely. Filtering from standard and enhanced certificates happens after six years for an adult simple caution, and never for offences on the specified list.
It is lighter than a conviction, which is not the same question as whether it is the right outcome. Accepting a police caution avoids attending court and avoids a criminal conviction, and it still creates a record that is disclosed on criminal record checks and reportable to a regulator. The comparison worth making is not caution against conviction, it is caution against no further action, and that depends on whether the police have enough evidence to support a prosecution at all. That is the question legal advice should answer before you accept a caution.
It can. On a basic DBS check it will not appear. On a standard or enhanced DBS check it is disclosed for six years, and permanently for specified offences, so it reaches regulated work in teaching, healthcare, law, finance and any role involving children or vulnerable adults. For anyone with a professional regulator, the referral obligation usually matters more than the certificate.
A conditional caution is disclosed on standard and enhanced DBS checks on the same basis as a simple caution. The point at which it becomes spent for basic disclosure is different, because a conditional caution is not spent while its conditions still have effect.
That is the other meaning of the word. The caution read before questioning begins "you do not have to say anything", and it is a warning about the effect of silence rather than a disposal. It is explained in our guide to the voluntary interview under caution. Being cautioned in that sense does not mean you have been given a police caution.
Parliament has legislated to replace them. Part 6 of the Police, Crime, Sentencing and Courts Act 2022 creates diversionary and community cautions and abolishes all other adult cautions, along with the penalty notice for disorder. Those provisions are not in force, so simple and conditional cautions remain the current law.
