The timetables for TfL services 298 and 699 will be altered from 3 September. 

Buses on the 298 will coninue to run at the same frequencies but some buses will be retimed to match altered traffic conditions, especially on the approaches to the M25 Motorway. 
Morning buses on the 699 are retimed, but there is no change to the afternoon service.
These changes should ensure that Sullivan Buses are able to continue to run reliable services on both routes.
