Credit for a guilty plea: how much less a sentence is
An adult who indicates a guilty plea at the first stage of proceedings usually receives a reduction of one third. The maximum falls to one quarter after that stage and to one tenth on the first day of trial. Different rules apply to murder, firearms and other minimum sentences.
The law
A court must take into account the stage at which a defendant indicated an intention to plead guilty and the circumstances of that indication (Sentencing Act 2020 s.73). The Sentencing Council's Reduction in Sentence for a Guilty Plea guideline, in force since 1 June 2017, sets the amounts for adults. Children are covered by a separate guideline.
The sliding scale
- First stage of proceedings (normally the first hearing at which a plea or indication of plea is sought): a reduction of one third. For cases that go straight to the Crown Court, an unequivocal indication of a guilty plea in the magistrates' court is normally needed for full credit (R v Plaku [2021] EWCA Crim 568).
- After the first stage: a maximum of one quarter.
- On the first day of trial: reduced to one tenth, and potentially to zero during the trial.
The reduction applies regardless of the strength of the evidence. It applies to the sentence the court would otherwise have imposed after trial, and can change the type of sentence. Since 22 March 2026, a prison term of 12 months or less must usually be suspended, subject to exceptions (Sentencing Act 2026 s.1), so credit can affect whether custody is immediate.
Exceptions
- Full credit despite a later plea is allowed only where particular circumstances significantly reduced the defendant's ability to understand the allegation, or made an earlier indication unreasonable. Waiting to see how strong the prosecution case is does not qualify.
- Newton hearings: if the defendant's version of the facts is rejected after a hearing, the reduction is normally halved.
- Murder: the reduction in the minimum term cannot exceed one sixth or five years, and there is none for a whole life order.
- Firearms minimum sentences: no reduction below the required minimum term.
- Other minimum sentences (for example, a repeat knife offence, third domestic burglary or third Class A trafficking offence): for adults, the sentence cannot go below 80% of the minimum. For 16 and 17 year olds convicted of the knife or offensive weapon offences, the minimum does not apply after a guilty plea.
In practice
The timing of a plea can make a large difference to a sentence. Advice on the evidence should come early, so that an informed decision can be made before the credit starts to fall. A guilty plea also usually means the case finishes sooner and witnesses do not have to give evidence.
