The booking office at Welham Green was APTIS equipped by November 1986, making it one of the very first stations with the ticketing system which was eventually found across the UK at all staffed British Rail stations by the end of the 1980s.
A booking office, open during the morning rush hour, is located on the northbound platform and is reached, from the west, through the station car park. A self-service 'Shere' ticket machine was installed in Autumn 2008 on the road overbridge, at the entrance to the northbound platform.
There are shelters on both platforms, and a small amount of seating near them.
The service from the station runs to Moorgate on weekdays until about 9:30 pm, and into London Kings Cross after 9:30 pm Mondays to Fridays and all day on Saturdays and Sundays.
The typical off-peak service is three trains per hour to Moorgate, reduced to two trains after 7 pm. However, Moorgate trains run only on weekdays up until 10 pm. Night and weekend trains run every 30 minutes to Kings Cross. There are three trains per hour to Welwyn Garden City, reduced to two trains per hour in the late evenings and at weekends.
