How bail works: police decisions, court hearings and 4 key conditions

Bail allows someone charged with an offence to remain at liberty while their case moves through the criminal justice system. The decision is made either by the police or by a magistrates' court, depending on when and how you are charged. HS Criminal Law explains who holds the power, what restrictions you might face and what happens if you breach them.

Police bail after arrest

When the police arrest you, they must decide whether to release you on bail or keep you in custody until your first court appearance. If they believe further investigation is needed but you do not pose a flight risk or a danger to others, they may grant police bail. This lets you return home while they gather evidence.

Police bail is granted by the custody officer — usually a sergeant at the police station. They can impose conditions or release you without conditions, depending on the circumstances. If you are released without charge, bail may still apply to ensure you return if the investigation continues.

Police bail is time-limited. The initial period runs for a maximum of 28 days, though it can be extended with authorisation from a superintendent or by application to a magistrates' court. Once the investigation is complete, you will either be charged, released without charge, or told that no further action will be taken.

Court bail and remand

If you are charged and brought before a magistrates' court, the court decides whether to grant bail or remand you in custody. The default position is that you have a right to bail unless there are substantial grounds to believe you will fail to surrender, commit further offences, interfere with witnesses or obstruct justice.

The court weighs the nature and seriousness of the offence, your past record, your ties to the community and any history of breaching bail. The prosecution may oppose bail and the defence can make representations. If bail is refused, you are remanded in custody until your next hearing or trial.

Bail can be granted unconditionally or with conditions attached. If conditions are imposed, they must be necessary and proportionate. A condition that is too onerous or not justified by the circumstances can be challenged.

Common bail conditions

Conditions are tailored to the case and to any concerns the police or court have about your conduct. The following four restrictions appear most often:

1. Residence: You must live at a specified address and remain there during certain hours, such as overnight. This reassures the court that you can be located.
2. Reporting: You must attend a police station at set times — often weekly or twice weekly — to confirm you have not absconded.
3. Non-contact: You are banned from contacting named individuals, typically complainants or witnesses, directly or indirectly. Breaching this can lead to further charges.
4. Exclusion zones: You are prohibited from entering certain areas, such as the street where an alleged victim lives or a town centre where an incident occurred.

Other conditions might include surrendering your passport, observing a curfew monitored by electronic tag, or providing a surety — a person who promises to pay a sum of money if you fail to appear.

Difference between police and court bail

Police bail applies before you are charged or while the investigation is ongoing. Court bail applies after you are charged and have appeared before magistrates. The two have different legal frameworks and time limits.

Police bail ends once you are charged or the investigation concludes. Court bail continues until the case is resolved, though you can apply to vary or remove conditions if circumstances change.

What happens if you break bail

Failing to surrender to custody — not turning up at court when required — is a criminal offence in its own right. You can be arrested, brought before the court and sentenced to custody or a fine. The court is also likely to refuse bail for the remainder of your case.

Breaching a bail condition is not itself a crime, but it gives the police or prosecution grounds to arrest you and bring you back to court. The court may then remand you in custody or impose stricter conditions. In some cases, breaching a non-contact order can lead to a separate charge, such as harassment or witness intimidation.

If you have a reasonable excuse for missing court — a medical emergency, for example — you should contact your solicitor immediately and provide evidence. The court has discretion, but the burden is on you to explain the failure.

Applying to vary bail conditions

If a condition becomes difficult to comply with, or if your circumstances change, you can apply to the court to vary or remove it. Your solicitor will prepare a written application setting out the reasons and any supporting evidence.

The prosecution will be invited to respond, and the court will hold a short hearing. Success depends on showing that the condition is no longer necessary or that a less restrictive alternative would suffice. A residence condition might be changed if you need to move for work; a reporting requirement might be reduced if you have complied without issue for months.

You cannot change police bail conditions yourself — you must apply to a magistrates' court if the police will not agree to vary them.

Unconditional bail and release under investigation

Not everyone released after arrest is placed on bail. Release under investigation means you are free to leave the police station without conditions and without a requirement to return on a set date. The investigation continues, but you are not formally on bail.

This approach has become more common since police bail was reformed. It gives the police time to gather evidence without the administrative burden of managing bail. However, it can leave people in limbo for months, unsure when or if they will be charged.

Unconditional bail, by contrast, requires you to return to the police station or court on a specific date but imposes no restrictions in the meantime. It strikes a balance between liberty and the need to ensure your return.

Steps to take if you are on bail

Being on bail places responsibilities on you. The following steps help you stay compliant and avoid further difficulties:

1. Understand every condition in writing. Ask for a copy of the bail sheet and read it carefully. If anything is unclear, ask your solicitor to explain it.
2. Mark court dates in a calendar you check daily. Missing a hearing is one of the most damaging things you can do to your case.
3. Keep evidence of compliance. If you must report to a police station, photograph the custody desk clock or keep the signed slip you are given.
4. Stay in contact with your solicitor. Tell them immediately if a condition becomes impossible to follow, or if anything happens that might affect your bail.

When bail is refused

If the court decides you should be remanded in custody, you will be held in a prison on remand until your next hearing or trial. Time spent on remand counts towards any custodial sentence you later receive, but it does not count if you are acquitted or given a non-custodial sentence.

You can apply for bail again at a later hearing if your circumstances change or if new information comes to light. The bar is higher on a second or third application: you must show that something material has changed since the last refusal.

Perverting the course of justice is a serious charge that can arise if you attempt to interfere with the bail process itself — for example, by providing false information to secure bail or by intimidating a surety.

Bail and serious offences

Certain offences carry a presumption against bail. If you are charged with murder, attempted murder, manslaughter, or rape and you have a previous conviction for one of those offences, the court must refuse bail unless there are exceptional circumstances.

For other serious crimes, such as robbery or grievous bodily harm, the court applies the usual test but is more likely to conclude that the risk of reoffending or absconding is too high. ABH and similar charges may still attract bail, depending on the facts and your record.

Youth and vulnerable defendants

If you are under eighteen, different rules apply. Youth bail is governed by the same principles, but the court has additional powers to impose conditions tailored to young people, such as a curfew supervised by a parent or a requirement to attend school.

Vulnerable adults — those with mental health conditions, learning disabilities or other support needs — may be granted bail with conditions that ensure they receive appropriate help. The court can require residence at a supported hostel or attendance at a mental health service.
