You need to be a bit more specific as there are too many variables here.
Best/most appropriate cable/wiring type varies with the type of circuit and nature of the building.
However it is generally considered that the best options are:
Steel conduit and trunking with single insulated cable for lighting and small power circuits.
Ladder/tray and SWA cable for distribution and large power circuits.
If we're working on the assumption that the market(s) aren't permanent fixtures so I'd be inclined to look at H07 for any temporary wiring (BS7909 style) if these markets 'plug in' to the fixed wiring then you'll likely be able to do tray/trunking/ladder with SWA/singles but that's broadly speaking, more information needed.
