I have tried dating it but so far it is a pretty wide slot which starts at 1939 and runs through into the 1950s.
That said I don't think it will be later than 1960.
I know it is an RT which were built for London Transport from 1939 onwards but they remained in service for decades.
Likewise it might be possible to date the make of the car and work out when it was registered but cars like buses have a habit of staying on the road for years which just leaves the building to our left in the main picture and the style of the clothes.
The directories will pinpoint the shop but men’s clothes remained fairly uniform from the 1930s well into the early 60s which just leaves the woman and her hat in the corner.
and the tram lines are missing so that I think will narrow it to the 1950s, which is just that bit more exciting given that this was the period I could have been there.*
All of that said it is quite clearly from a time well before now and what draws me to the photograph is the sheer bustle and the way the photographer caught a moment
