As King-Maker is implicitly suggesting, UK income tax is not leviable on certain UK source income arising to non-UK residents (eg UK bank interest); income tax on dividend income is restricted.
The possible "capping" of a non-UK resident's UK income tax liability to which you refer still operates under the guise of "disregarded income" in certain cases.
If you are, inter alia, British nationals you are entitled to personal allowances.
The UK/Chile double tax agreement is of little help I believe.
