There is a hobby shop close to the intersection of Holborn and Kingsway that had some models though I can't say for sure they had Herpa models.
That hobby shop, near the Holborn/Kingsway, is called Modelzone (MZ). It does not sell Herpa models, but it does have a small selection of diecast and snap-fit airliner models at one end of the store. The diecast models are GeminiJets 1:400 and 1:250, and there are SkyMarks 1:200 snap-fit models. But no Herpas, sorry!
(I'm a regular at that shop, as I live within walking distance of it!)
