They want to make officers visible in the community.
Leicestershire Police have announced that the iconic custodian police helmet and Bowler are part of the uniform again for patrolling police officers.
The distinctive domed helmet for male officers and bowler hat for female officers were removed several years ago in favour of the bump cap.
They are making the change after the jubilee 'as a renewed commitment to standards and to officers being more visible in our communities'.
Temporary Chief Constable Rob Nixon said: “In a crowd, British policing’s traditional helmet and bowler hat are instantly recognisable.
"People know they can approach an officer for help. We have brought in the new rollout in The Queen’s jubilee year to strengthen that link between the public and the police and to celebrate the oath we swear to Her Majesty.
“Our officers are proud to wear the uniform and we know the public want to see us out on the beat keeping people safe.
“This visible reminder will help our officers stand out in an approachable and recognisable way so we can deliver an even better service."
Police and Crime Commissioner Rupert Matthews said: “I fully welcome the return of this piece of uniform in the Queen’s Jubilee year. Improving uniform standards is part of improving the service to the public.
"I equate this helmet to the police officer I used to know, whom I was able to spot in a crowd and know I could approach for assistance. This brings a sense of tradition back to Leicester, Leicestershire and Rutland but also will build confidence in policing throughout the city and two counties.”
