Police Officer recruitment in the UK
In theory, anyone who is British, an EU/EEA national, or a Commonwealth Citizen, or a foreign national whose stay in the UK is unrestricted.
But there are other conditions too. At the moment the minimum age is eighteen. You must not have a criminal record, although minor offences committed when you were a juvenile don't necessarily rule you out. Police forces will accept applicants with glasses or contact lenses if your un-aided vision is reasonable, and you'll need to be mentally and physically fit and well. There are no height or official maximum age restrictions.
