Guide for Prison Officer
This guide explains how part-time FTE affects gross pay for Prison Officer on Prison Band 3 at Probation & Prisons. Pro-rata rules can vary; check your contract and HR team.
Part-time pay for Prison Officer
As Prison Officer at Probation & Prisons, part-time pay is usually pro-rated from full-time basic pay on your band or grade (Prison Band 3 on HMPPS pay (Prison & Probation)). Enter your FTE (for example 0.8 for a four-day week) to compare with full-time gross pay. Unsocial hours, HCAS and other enhancements are calculated on actual basic pay where they apply.
Part-time and FTE explained
Full-time equivalent (FTE) compares your contracted hours to a full-time post. 0.8 FTE usually means four days out of five: pay is typically pro-rated to 80% of the full-time salary for the same band. Employers may round or apply local rules, so treat results as a guide.
Progression and pension
Many public sector employers count part-time service at full rate for incremental progression, but not all do. Pension is different: in the career average schemes most public sector staff now build up pension in, each year adds pension based on the pay you actually earn, so a year at 0.8 FTE adds about 80% of a full-time year. Check your contract for progression dates and your pension scheme for how part-time pay affects your pension.
