Short prison sentences are set to become far less common following the introduction of a major sentencing reform that came into force on Monday 23 March 2026.

The changes, introduced under the 2026 Sentencing Act, are designed to ease prison overcrowding and improve rehabilitation outcomes. Under the reform, courts will stop imposing short sentences other than in exceptional circumstances, with judges allowed to suspend sentences of up to three years. The legislation doesn’t define ‘exceptional circumstances’, with decisions left to magistrates and judges on a case‑by‑case basis.

Experts have long questioned the effectiveness of short jail terms, according to BBC News. Government statistics show that more than 6,000 people are serving sentences of up to a year at any one time. Recent Ministry of Justice (MOJ) proven reoffending statistics also point to high reoffending rates among those given short sentences. Adults released from sentences of less than 12 months had a proven reoffending rate of 66% in the January to March 2024 cohort, up 9.1 percentage points on the same period in 2023.

Campaigners have argued that community‑based rehabilitation is both more effective and less costly than short periods in custody. That view was echoed by former Conservative Justice Secretary David Gauke, who reviewed sentencing policy for the Labour government and made recommendations as part of the reform process.

A MOJ spokesperson said that the measures wouldn’t abolish short sentences entirely, but would instead "make sure prisons never run out of space again, while strengthening the supervision of the most dangerous offenders”.

Chair of the Criminal Bar Association Riel Karmy-Jones KC said the reforms would  take effect immediately, including on court backlogs, as they’re expected to help speed up proceedings and encourage earlier pleas. She commented: "The pressure on prisons will be lessened, with more places available for those serving longer terms, especially violent and sexual offences, together with providing them with the additional rehabilitation services.

"This is an important measure, as it will help to prevent them from reoffending when finally released, ultimately providing the best protection for the public."

The reforms also include changes to bail rules. Defendants who are likely to receive a suspended sentence if convicted will now be less likely to be remanded in custody ahead of trial. More than 16,000 people are currently held on remand, accounting for around one-fifth of the total prison population.

In addition, courts will be able to defer sentencing for up to 12 months, double the previous limit, where this is considered necessary, to give an offender time to address underlying issues contributing to their offending, such as drug addiction.
