When do the release changes apply?

The new release points do not reach everyone on the same day. People already in custody move across in monthly stages, shortest sentences first. Enter a sentence length to see which stage it falls in.

The start date is now set in law: 1 October 2026

The progression model was originally due to start on 2 September 2026. It was paused, and the The Sentencing Act 2026 (Commencement No. 6 and Revocation) Regulations 2026 (SI 2026/953), made on 1 September 2026, set the start at 1 October 2026 and revoked the earlier regulations. The same instrument puts the excluded offences into law: those release points do not move.

The stages below are the confirmed dates on which the change reaches people already in custody, shortest sentences first.

Two things the stages do not cover

  • Sentenced on or after 1 October 2026? The new release point applies straight away. The staged schedule only governs when the change reaches people already serving a sentence.
  • Already out on a curfew licence? Someone released on licence with a curfew condition under section 253 of the Criminal Justice Act 2003 before 1 October 2026 is not reached until 12 October 2027, whatever their sentence length (SI 2026/953, regulation 4).
  • Under 18 at sentence? Youth detention under section 250 of the Sentencing Code and section 91 of the Powers of Criminal Courts (Sentencing) Act 2000 is left out of the change entirely (SI 2026/953, regulation 6). Those release points stay where they are.

The revoked schedule

Regulation 3 of The Sentencing Act 2026 (Commencement No. 4) Regulations 2026 (SI 2026/609).

Revoked on 1 September 2026. It never took effect.
