There are a lot around tottenham court road station. Cameraworld http://cameraworld.co.uk Jessops http://www.jessops.co.uk (expensive) Jacobs http://www.jacobsdigital.co.uk/ (Jessops clone) There are a bunch more along new oxford st & towards the british museum like Aperture (I think)
Jessops may price match, so it is worth going forarmed with a magazine & prices from other places.
There is a "pro" store in Drummond St next to Euston Station. (KJP / Calumet ?)
