What is the On Call Allowance?
A member of the rank of Constable, Sergeant, Inspector or Chief Inspector shall receive an allowance of £15 in respect of each day on which he spends any time on call.

"Day" means a period of 24 hours commencing at such time or times as the chief officer shall fix after consultation with the Joint Branch Board, and the chief officer may fix different times in relation to different groups of members.

The agreed Force working Day varies from force to force so if you are "on call" for out of office hours your claim may straddle two working days and not one.
