Great News! That will make a huge difference for the UK users.
It usually is Country, County, City with the city data also including towns.
The final field location that is used at the moment for the UK is good, it just needs the "County" field before it in the hierarchy.
So that is:
England, County, Final location
Scotland, County, Final location
Wales, County, Final location
Northern Ireland, County, Final Location
Thanks again for all your help :-)
