Since October 2009, part of the route from Eltham to Bexleyheath has been covered at night by night bus route N21.[7]
During the London 2012 Olympics, the route was temporarily converted from single-decker to double-decker operation.[8] The route was permanently converted to double-decker operation in December 2012.[9][10]
On 12 September 2015, the route gained a 24-hour service on Friday and Saturday nights. At the moment, the 24-hour service on Friday and Saturday nights is suspended due to the COVID-19 pandemic.[11]
In January 2020, the daytime frequency of the route was increased from a bus every 10 minutes to a bus every eight minutes.[12][13]
