For historical reasons, the Home Secretary is responsible for London's Metropolitan Police Force, advised by the Metropolitan Police Committee. For the City of London Police the authority is a committee of the Corporation of London. Provincial forces are headed by a chief constable, deputy chief constable and assistant chief constable. The top Metropolitan Police ranks are the commissioner, deputy commissioner, assistant commissioner, deputy assistant commissioner and commander. Thereafter all ranks are the same in the forces - chief superintendent, superintendent, chief inspector, inspector, sergeant and constable.
Most forces use customer surveys to provide information on public attitudes.
These are used to shape the standards of service being provided. The heart of policing is the work done by police constables, who are in constant contact with the public. They patrol the streets on foot, or in cars, give advice and deal with disturbances. The police are closely involved in setting up 'neighbourhood watch' schemes, advising residents on home security and encouraging residents to keep an eye on properties in their area and pass on information to the police about suspicious people or vehicles. There are about 150,000 full-time police officers in Britain, of whom around 12 per cent are women.
