Assumptions and pay data
Pay data: HMPPS pay (Prison & Probation). Prison Band 7: one rate of £54,148, 2026/27 figures. Checked 4/9/2026.
- How we model progression: Many UK public sector pay scales use spine points (fixed salary steps within a band). Where the dataset has spine points, we assume you move up one point every X years (e.g. every 2 years). Where there are no spine points, we use an annual increment until you reach the band maximum. Real rules (time in grade, performance, etc.) vary by employer and contract.
- Years in role (starting point): This is how many years you have already been in this band. It sets where you start on the scale for the projection (e.g. 0 = bottom of the band (year one), 4 = four years in (you may already be at a higher spine point)). Change it to match your situation.
- All outputs are gross. We don't deduct UK tax, National Insurance or pension.
- Allowances and eligibility vary by UK employer.
Progression is shown using the pay structure for your sector (spine points or annual increments). Rules and rates vary by employer, so treat this as an illustrative guide only.
