UK keyboards on PCs have a dedicated key for #/~, " is shift-2 and @ is shift-'. £ (currency symbol) is shift-3.
On a Mac the " and @ are the wrong way round (shift-' and shift-2 respectively), and the key that should produce # instead generates \. The only way to get a # is option-3, which is not marked on the keys. The Mac "UK" layout is basically the US layout with £/# reversed.
