Pay data: HMPPS pay (Prison & Probation). Prison Band 9: £73,513 to £80,864 over 4 pay points, 2026/27 figures. Checked 4/9/2026.
- Both paths use today's pay scales, with no pay awards, and count gross pay only.
- The calculator starts you at the first point of the new band.
- Each year in the comparison moves you a year up your band before pay is worked out, so the “promoted later” path is paid £75,963 in its first year.

Guide for Deputy Governor
This guide helps Deputy Governor at Probation & Prisons compare promotion timing scenarios from Prison Band 9. The calculator shows gross earnings only; promotion still depends on vacancies, funding and employer policy.
Why promotion timing matters for Deputy Governor
Moving to a higher band or grade earlier means more years at the higher rate. Over five or ten years the cumulative difference can be substantial, even when the step from Prison Band 9 to the next band looks modest year to year. This tool compares gross earnings under two promotion timings using illustrative pay from HMPPS pay (Prison & Probation).
Typical progression for Deputy Governor
Senior Head of Function → Deputy Governor → Governor (Band 10) → Governing Governor (Band 11). Use the calculator on this page to model Band 9 pay.
What to compare in the calculator
Set your current band (Prison Band 9), years already in band, and how far ahead to project. Choose when the first promotion happens in each scenario and the target band after promotion. Optionally add a second promotion step for longer career routes.
Real world factors
Promotion depends on vacancies, performance, funding and policy. The calculator does not model competition for posts or time to complete training. Use it for financial comparison alongside career planning conversations with your line manager or union.
Example scenario
Example: Prison Band 9 at £73,513. Promotion now rather than in 3 years is worth £33,175 over 10 years; the calculator opens on promotion in 1 year (£13,509).

Can I compare a second promotion?
Yes. Tick “Model a second promotion”: it opens on Prison Band 11 in year 5, and you can change both.
