Pre-Arranged Overtime (PAO) is overtime worked at 1.5× your basic hourly rate, paid for time worked beyond your contracted 42-hour week. PAO is the standard mechanism for paid overtime under the NJC Grey Book — distinct from unplanned operational over-runs and recall-to-duty arrangements which can have their own treatment.

PAO is available to Firefighter, Crew Manager, Watch Manager and Station Manager grades. Group Manager and above are not eligible — they're on the Conditional Service Agreement and instead receive the FDS allowance for on-call working.

PAO earnings are pensionable under FPS rules. Tax and NI are deducted as normal. A typical operational firefighter working 10 hours of PAO per month at Competent earns an extra £3,196/year gross (10 × £26.63 × 12).

Frequently Asked Questions

How is firefighter overtime calculated?
Pre-Arranged Overtime is paid at 1.5× your basic hourly rate. For a Competent firefighter (£17.75/hour basic), PAO is paid at £26.63/hour. Higher ranks earn proportionally more per PAO hour.
Who is eligible for PAO?
Firefighter (Development and Competent), Crew Manager, Watch Manager and Station Manager grades are all eligible for PAO. Group Manager and above are not — they're on the Conditional Service Agreement and receive FDS instead.
Is PAO pensionable?
Yes. Pre-Arranged Overtime counts as pensionable pay under the Firefighters' Pension Scheme rules — both the FPS 2015 (CARE) and the legacy 1992/2006 schemes.
What is the PAO rate for a Competent firefighter?
A Competent firefighter on £17.75/hour basic earns £26.63/hour for PAO (1.5× multiplier). Working 10 hours of PAO per month adds around £3,196/year gross.
How much do firefighters typically earn from PAO?
It varies enormously by FRS, role and personal availability. Typical operational firefighters might do 5–20 PAO hours per month; some specialist roles or busy stations significantly more. The calculator lets you enter your expected monthly PAO hours to see the impact on annual pay.
