There are actually quite a few choices when it comes to acquiring a Taxi Licence in the UK, each with their own pro's and con's. Some licences are more suitable than others, depending on your personal circumstances, requirements and location.
The three types of London licences are, the All London (Green Badge) licence, Suburban (Yellow Badge) licence and London Private Hire licence. See table below for further details.
Outside of London generally there are two types of licences, the Hackney Carriage Licence and the Private Hire Licence which need to be applied for through the local authority or council in the area in which you would like to work.
