If a trademark is not a generally known geographic location to the average UK consumer, then, a trademark containing a geographic location should be registrable.
Trademarks containing geographical place names are likely to receive objections when they designate a geographical name which, in the minds of the target consumers, is already associated with the products or services offered.
Also, an objection is likely to be raised even if there is no current association between the geographical name and the goods/services, but the name is likely to be used in the future by a company as an indication of the geographical origin of the goods/services concerned.
A trademark that will most likely be refused by the USPTO as being geographically descriptive and therefore not registrable on the Principal Register (and not eligible for Amazon Brand Registry) will most likely go through in the UK.
