Factual error: During the celebrations for the end of World War II, cars can be seen in the background that were made long after 1945. Also in this scene in the shot of Piccadilly Circus, the BMC {British Motor Corporation} rosette logo can be seen among the adverts. BMC wasn't formed until 1952.
Factual error: Alf and Mike go into the pub for a drink on their way to watch the 1966 world cup final. Parked outside the pub is a car with an E registration plate which means it was first registered between January and July 1967.
