The 20 is directly descended from the 38 Group of Routes, but owes its number to historical route 10 group, which operated for eighty years from 1908 until 1988 between Victoria, Aldgate, Stratford, Leytonstone, Woodford, Chigwell to Abridge and also via Loughton to Epping.
The 20 commenced operation on 7 September 1968 as a direct replacement of the 38A from Loughton to Leyton with an extension to the newly opened Walthamstow Central station on the Victoria Line. At the time of the route 20 introduction, there were already two other routes in the Loughton area with 20 numbers, the 20A and 20B. As the new route ran parallel with the 20A for many miles, the new route was titled 20.
- On school days there is one additional journey Walthamstow to Debden AM, return PM.
The route first started off using RTs. The RTs were then replaced with Daimler DMS buses until about the early 1980s when it started using Leyland Nationals and Leyland Titans. When Eastern National took over after the demolition of Loughton garage in 1986, they used Leyland Nationals and Bristol VRs. Cowie Group (who later renamed themselves Arriva) then took over using new Alexander ALX200s and Volvo Olympians. In 2003 they bought new Wright Eclipse Geminis until early 2007 when they replaced them with older DAF DB250LF/Alexander ALX400s.
