By Train - Some Metropolitan Line tube trains terminate at Chesham during peak times, however for journeys off-peak, change at Little Chalfont for the Chesham shuttle service. The station is a 3-minute walk from our office. From the station turn left towards the town centre. At the bottom of the hill, turn right and we are 150 meters along on the left near Barclays and Lloyds Bank and opposite the Post Office.
