How Long Can the Police Hold You in Custody in the UK Without Charge?
When someone you love has just been arrested, the question of how long can police hold you without charge in the UK sits right at the front of your mind, and it deserves a straight answer. The starting point is 24 hours, and it can stretch to 96 hours, or even 14 days for terrorism cases.
The rules come from the Police and Criminal Evidence Act 1984 (PACE). They exist so that nobody sits in a cell indefinitely without good reason and proper oversight from someone outside the investigation.
Below, we set out when the clock starts, who signs off on each extension, what your rights are while you wait, and what tends to happen once the custody period ends. These are the custody time limits in the UK that every solicitor works from, whether you are the person in the cell or the family member waiting for a phone call.
Custody Time Limits at a Glance
The 24-Hour Rule: 24 Hour Police Custody in the UK Explained
The basic position under PACE is straightforward. Without a charge being brought, the police can hold you for 24 hour police custody in the UK as a standard maximum. What trips people up is working out exactly when that clock begins.
The 24 hours runs from the "relevant time" — usually the moment you arrive at the police station, not the moment of arrest itself. If you are arrested some distance away, the travel time does not count against you. The clock only starts once you are booked in.
There is one small exception worth knowing. If you are arrested in one police area and need to be transferred to another for the investigation, the relevant time can shift slightly to reflect the journey, but this is rare and closely regulated. Custody staff must record the exact time on your custody record, which your solicitor can request and check.
A custody sergeant, independent of the investigation, must review your detention regularly during this period. This is not a formality. They are required to ask whether continued detention is still necessary, and release you if it is not. If the grounds for holding you have weakened, they must say so and act on it.
Breaks for rest, food, and sleep are also built into this period, and custody staff are expected to allow at least eight hours of continuous rest in any 24-hour cycle, wherever practicable. None of this extends the clock; it simply governs how those hours are spent.
36-Hour Extension Under PACE: Who Authorises It and Why
If officers need more time, they can apply for a 36-hour extension PACE allows for. This is not automatic. A police superintendent, or someone of equal or higher rank, must personally authorise it, and they have to record their reasons in writing on the custody record.
Two conditions have to be met: the offence must be indictable (serious enough for the Crown Court), and continued detention must be genuinely necessary to secure evidence or to question you further about it. Indictable offences typically include things like robbery, serious assault, drug supply, and fraud above a certain scale.
The superintendent should also consider whether the investigation has in fact been progressing during the first 24 hours rather than simply sitting idle before authorising an extension. Delays caused by staff shortages or waiting for forensic results do not automatically justify keeping someone in custody longer.
Timing matters. The authorisation must be granted before the original 24 hours runs out. Miss that window, and the police must charge you, bail you, release you under investigation, or let you go with no further action. A solicitor will often challenge an extension request directly with the authorising officer if the justification looks thin.
96-Hour Police Detention: The Magistrates' Court Warrant
For the most serious cases, the police can apply to a Magistrates' Court for a warrant of further detention. This is what people mean when they ask about 96 hour police detention — the outer limit for anyone not suspected of terrorism.
A magistrate will only grant this if satisfied the investigation is being conducted diligently, without unnecessary delay, and that there are reasonable grounds for further detention. You, or your solicitor, are entitled to attend and make representations at the hearing, and the court can refuse the application outright.
The police cannot arrange this quietly behind closed doors. A representative usually has to attend court in person, present evidence to justify the request, and answer questions from the bench. If the magistrate is not convinced, detention ends and one of the usual outcomes, such as charge or bail, must follow immediately.
The application must also be made before the previous authorisation expires, or the detention becomes unlawful. Warrants of further detention are, in practice, relatively rare and tend to appear in complex fraud, drugs, or violent crime investigations where evidence takes real time to gather and verify.
The 14-Day Terrorism Exception
There is one major exception to all of this. Under the Terrorism Act 2000, anyone arrested on suspicion of a terrorism offence can face terrorism 14-day detention without charge. This is significantly longer than any other category of offence in England and Wales.
Anything beyond 48 hours still needs judicial approval, reviewed at set intervals by a senior judge rather than a magistrate. Each extension request has to be argued in front of the judge, with the police setting out precisely why further time is needed and what steps they have taken so far.
It reflects the complexity of terrorism investigations, often involving multiple jurisdictions, encrypted devices and working with agencies like MI5 or counter terrorism policing units. Even so, the core safeguards, including legal advice and regular reviews, still apply throughout, and detainees retain the right to challenge their detention.
Your Rights in Custody
Whatever the length of detention, certain rights stay the same. You are entitled to:
- Free legal advice, regardless of income, and you can choose your own solicitor rather than the duty solicitor on shift.
- Have someone informed of your arrest and whereabouts, such as a family member or friend.
- Regular custody reviews — the first no later than six hours after detention was authorised, then roughly every nine hours, carried out by an officer not involved in the case.
- Reasonable welfare provisions, including food, rest and medical attention where required.
If you're under 18 or deemed vulnerable due to a mental health issue, learning disability or language barrier, you have a right to an "appropriate adult" during interviews. This is someone independent of the police whose role is to support you and make sure you understand what is happening.
Interpreters must also be arranged, at no cost to you, if English is not your first language or if you have a hearing impairment. The police cannot proceed with a formal interview until suitable arrangements are in place.
If you take one thing from this article, take this: ask for a solicitor before you say anything else. It costs nothing, and it changes everything that follows.
What Happens When the Clock Runs Out?
Once the relevant custody period is reached, the police must do one of the following:
- Charge you with an offence, after which you will usually appear in court the next working day.
- Release you on pre-charge bail, with conditions attached and a date to return.
- Release you under investigation (RUI), meaning no conditions but the case stays open.
- Release you without further action, closing the matter completely.
Which route the police take usually depends on the strength of the evidence gathered so far, how serious the allegation is, and whether they believe further enquiries, such as forensic testing or witness interviews, are still needed. None of these outcomes are final in themselves, and each can be revisited as an investigation develops.
If you are bailed or released under investigation, our guide to pre-charge bail explains conditions, breaches, and how long the process typically runs. It is worth reading closely, since breaching bail conditions can itself lead to further arrest.
How a Solicitor Helps While You Are in Custody?
A solicitor's job at the station is not just to sit beside you. They check the custody clock is being applied correctly and challenge extensions that are not properly justified, often raising concerns with the custody sergeant or superintendent directly.
They also advise you on whether to answer questions or give a prepared statement, and push for early engagement with the investigating officer where it might help close the case before charge. This kind of early intervention can, in some cases, prevent a charge from being brought at all.
Involving a solicitor early, ideally before the first interview, consistently makes the biggest difference to how a case unfolds. A good solicitor will also monitor welfare throughout your detention, flagging anything from missed meals to delayed medical attention.
Common Misconceptions About Custody Time Limits
A few myths tend to circulate about how this process works, and they are worth clearing up. First, the police cannot simply keep someone in custody "for as long as they want" — every extension needs written authorisation and a genuine, recorded justification.
Second, staying silent in an interview does not automatically extend your detention or count against you at the extension stage, though your solicitor will discuss the wider implications of silence with you separately. Third, weekends and bank holidays do not pause the clock; the hours run continuously regardless of the day.
