Not likely gonna be one locally when I asked this was the response your local camping shop might stock ledlensers and maglite, if your luck maby a fenix, military shops might have one or two other lights if ur again very lucky, maplin normaly has some but not any of the main brands I have seen on here just ledlensers ect.
Only chanchr of seeing these will be to go to a CPF meet, there is one in the Brighton area sometimes I think, other than that you would have to find a flashlight shop but it won't be a chain store and may be the other side of their country, best option would be to go to a importer of the brand you want and see if they will let you have a play before you pay.
Or you can order one try it and send it back if its an amazone pitches as they have a good return policy but its a bit cheeky and more Hassel than is be willing to bother with.
So short answer not really no.
