There is important guidance available for existing and prospective taxi drivers on completion of the Disclosure Barring Service (DBS) form. You must have a DBS disclosure certificate before you can be licensed to drive a hackney carriage or private-hire vehicle. New or renewal applications for taxi licences will not be processed without one.
You can see the current Hackney Carriage fares rates for Runnymede on this page, which have been in place since June 2014. These fares will be reviewed each year from 2015 onwards.
