@Nathan_SR - Just had a go at loading the keymap out of your .zip file, but loadkmap doesn't recognise its format.
Did you gunzip the qwerty-uk.map.gz file, before trying to load it with the loadkmap command ?
Hope and wish it gives you the pound symbol back in no time ! This is a latest release from the kbd package. If it does not work, then we may need to look at the LANG and the LC_CTYPE environment variable and set it, as given in my post earlier.
