The news seems to be constantly featuring stories concerning the overcrowding crisis in the country’s prisons. Much to the dismay of most of the general public, early release of prisoners, will be going ahead with some changes about to be implemented next month.
The law governing the release of prisoners in England and Wales is changing from 1 October 2026. The Sentencing Act 2026 (Commencement No. 6 and Revocation) Regulations 2026 introduce significant amendments to the point at which certain prisoners serving determinate sentences become eligible for release from custody.
Whilst these changes will not alter the sentence imposed by the court, they may substantially reduce the amount of time some offenders spend in prison before being released on licence.
What Is Changing?
The reforms apply to many adults serving Standard Determinate Sentences (SDS), which are the most common type of fixed-term custodial sentence imposed by the Crown Court and Magistrates’ Court.
Previously, prisoners serving these sentences would often be released automatically after serving:
- 40% of their sentence;
- 50% of their sentence; or
- Two-thirds of their sentence,
depending upon the offence and sentencing provisions in force at the time.
Under the new arrangements, eligible prisoners will generally be released after serving:
- One-third of their sentence where the previous release point was 40% or 50%; or
- One-half of their sentence where the previous release point was two-thirds.
The overall sentence imposed by the court remains unchanged. The offender will continue to be subject to licence conditions following release and can be recalled to prison if those conditions are breached.
Examples of the Change
To understand the impact of the new legislation, consider the following examples:
| Sentence Imposed | Previous Release Point | New Release Point |
|---|---|---|
| 12 months | 6 months (50%) | 4 months (1/3) |
| 18 months | 9 months (50%) | 6 months (1/3) |
| 2 years | 12 months (50%) | 8 months (1/3) |
| 3 years | 18 months (50%) | 12 months (1/3) |
| 6 years | 4 years (2/3) | 3 years (1/2) |
These examples illustrate how the custody period for some prisoners may be significantly shortened whilst licence supervision continues for the remainder of the sentence.
Why Has the Government Introduced These Changes?
The reforms form part of wider measures designed to address sustained pressure on the prison estate in England and Wales. Rising prisoner numbers and limited prison capacity have led policymakers to consider changes to release arrangements as a means of managing overcrowding.
The Government has made clear that these changes do not amount to shorter sentences. Courts will continue to impose sentences in the usual way. The reforms instead alter the proportion of the sentence which must be served in custody before release.
Will Every Prisoner Benefit?
No. The changes do not apply universally and there are important exceptions. Certain categories of offenders, particularly those convicted of the most serious offences, remain subject to separate release provisions.
Whether a prisoner qualifies for earlier release will depend on the precise sentence imposed, the offence committed and the applicable statutory framework.
For that reason, it is important not to assume that every prisoner serving a determinate sentence will automatically benefit from the new rules.
What Does This Mean for Victims and Families?
The reforms are likely to be controversial. Victims of crime may be concerned to learn that offenders could spend less time in custody than would previously have been the case. Equally, families of prisoners may welcome the prospect of earlier reintegration into the community.
Regardless of personal views on the policy, the practical effect is that release dates for many prisoners could change from 1 October 2026 onwards.
Seeking Advice About a Sentence
Understanding release provisions can be complex. Two prisoners serving what appears to be the same sentence may have different release dates depending on the nature of the offence, sentencing legislation and transitional provisions.
If you or a family member is serving a custodial sentence and you are unsure how these changes may affect a release date, specialist legal advice should be obtained. Careful consideration of the sentencing remarks, warrant of commitment and applicable legislation is often required before an accurate assessment can be made.
