Yes, if you use UK layout on ANSI board you loose the \| key next to Z since is doesn't physically exist. Many of my UK friends use modified US keymap, with making the £ as the shifted character over the 4 with the $ as an alt gr character. You can use MSKLC to accomplish this or Xmodmap if on nix. Or maybe one of the UK folks that use that can even send you their keymap file?
