If you mean 'Can a judgment in a foreign court to recover foreign taxes be enforced in the English Courts?' the answer has been 'No' for as long as anyone can remember. Likewise a foreign country can't bring an action here to recover tax due under its laws. It's a principle of 'conflict of laws' (the international law established over time) that the English courts will not entertain an action for foreign revenue (and vice versa) .
A leading case which explains this principle in robust terms is Governent of India Ministry of Finance (Revenue Division) v Taylor reported at [1955] 1 All ER 292 and [1955]AC 491 which you can read here:

Now, I can't guarantee that the principle has suddenly been abandoned or changed recently but , particularly as you are concerned with non EU countries,that would seem very unlikely, given that it is pretty fundamental to international law.It's what countries dealing with English courts accept. (As ti the EU,I'm not aware of French taxes being enforceable in England: the authorities there rely on seizing assets or income originating in France or seizing and freezing bank accounts etc which happen to belong to the taxpayer and are within France. And,of course, any country in the world might have laws allowing it to seize the taxpayer himself if he enters the country)
