There is escalator access between the lower concourse, and FCC Stevenage service, platforms 9 - 10. There is also escalator access between the lower concourse and the Northern Line, platforms 7 - 8.
There is a single up escalator from the Northern Line to the FCC Stevenage service and we understand there is normally escalator access between the eastbound Metropolitan Line, platform 1 and the Stevenage Service. These latter were out of use at the time of our survey.
Of the escalators between the lower concourse and Northern Line, the right-hand escalator is normally the one you need, whilst for those between the lower concourse and Stevenage service, you normally need the left.
