A Suffolk Constabulary officer received nearly £50,000 in overtime payments last year, with the total bill hitting almost £5million.
The officer, who has not been named, was one of 25 officers who all earned more than £15,000 on top of their normal salaries in 2024/25.
They received £48,253.42 for working over their usual hours - more than double the next highest of £24,082.21.
A total of £4,205,610.39 was paid to 1,236 officers during the financial year - an average of just under £3,500 per officer.
Suffolk Police and Crime Commissioner Tim Passmore said the "huge number of additional hours" has prompted "concerns for the health and wellbeing of these officers."
"We are grateful for the flexibility of officers to cover the demands of policing in the county.
"The willingness of officers to go the extra mile is remarkable.
“Some of these officers do seem to be doing a huge number of additional hours and I do have my concerns for the health and wellbeing of these officers. We have a responsibility to protect staff and this should be paramount.”
Of the top 25 earners, 24 were male and there was one female.
Seven officers of the top 25 earners received more than £20,000 for the overtime they clocked up.
The Freedom of Information request reveals on top of the £4,205,610.39 paid to officers, a further £680,879.49 was paid to 547 staff members.
A spokesman for Suffolk police said: "Police work is challenging and demanding, often requiring the immediate deployment of resources to deal with a range of emergency situations. Our priority in all these situations is to keep people safe.
“To do this, we need to have a workforce of officers and staff that can be flexible, particularly when involved with long-running, significant incidents.”
The spokesman added budgets and services are "continually reviewed".
"A proportion of both annual budgets is set aside for overtime payments, and this is regularly reviewed to reflect requirements," said the spokesman.
“Overtime can be the most cost-effective means of dealing with demands outside of day-to-day policing.
"Many events and/or incidents that are policed during the course of the year require police resources over and above those that would be required for everyday policing.
"Often a large proportion of the reported cost is recovered when support is given to other forces or when policing services are provided by police officers required for events such as festivals."
