You can see the current Hackney Carriage fares rates for Runnymede on this page, which have been in place since June 2014. These fares are reviewed each year.
Following a Meeting of the Regulatory Committee on 9 April 2015 the table of fares has been amended to clarify that drivers are prohibited from having meters calibrated so as to change tariff when they are in hired mode. Information on this can be seen on the Taxi and private hire news and information page.
