Assuming that an increase in tolls would have taken place, uprating the 2008 frequent traveller cost of £207 annually to allow for inflation would mean a bridge toll in 2013 of £233 per annum, the amount a commuter would save in 2013 if tolls had not been abolished. This is an increase of £26 or 12.6% since 2008. This uprated figure is calculated using GDP deflators from the latest National Accounts figures produced by the Office of National Statistics and HM Treasury forecasts.
