Back pay (gross)
£0
The 3.5% pay rise is backdated to 1 September 2026. If your force pays it late, you are owed arrears. Work out exactly how much, gross and after deductions.
Arrears owed from 1 September 2026
Estimate only. Back pay is taxed through PAYE in the month it is paid.
When the award is applied late, every month you were paid at the old rate is topped up to 1 September.
The 3.5% rise takes effect from 1 September 2026. If your force cannot process it in time, the increase is backdated to that date.
For each month you are still paid the old salary, you are owed the difference between your old and new pay for that month.
When payroll catches up, the arrears arrive together. Because PAYE taxes it in one month, that payslip can look heavily deducted, then evens out.
Back pay is a one-off. Use the Pay Rise Calculator to see your new ongoing monthly take-home after the 3.5% award.

The 2026/27 award takes effect on 1 September 2026. If a force cannot run the new figures in the September payroll, it applies them later and backdates to 1 September.
The arrears are then paid as a single lump sum in the catch-up month.
