This page provides an insight into the breadth of services that are in existence in the UK or have become defunct over the last century.
The table below shows how we have come to have the service names that are in existence today. It shows the hundreds of railway police forces that have become the British Transport Police. It shows the 2006 shake up of ambulance services into larger territories. It also shows some unusual services from the past, such as the Barnet Dog Handlers and the British Legion Volunteer Police Force (which existed for just 10 days).
The table covers from Shetland in the North to the Channel Islands in the South. It also covers historic services from the Republic of Ireland from when this was part of the United Kingdom.
