Here’s how we calculated it

We took 1461 days as the sentence, applied Ordinary SDS — 40%, subtracted 0 remand days, and counted forward from 1 March 2026.

This is not the prison’s figure. Offence type, SDS40 eligibility, additional days, HDC and recalls all move the date. Only the prison / offender manager can confirm it. Last checked 10 September 2026.
