> But if you offer paid servies, collect money from UK citizens, you must have a business representation in the UK

I don't think that's true at all. You be taking payment by credit card, which doesn't require you to have any local presence.

I think your bigger risk is that you get a judgement made against you by a UK court, which a court that has jurisdiction over you is willing to enforce. I'm not sure under what circumstances that is the case, but I believe that it being the case with libel judgements has been an issue for a while (since plaintiffs can 'forum shop').

But you're offering an online product, plus you are taking money from people from all over the world, whose governments have different regulations and points of view, your own business charges differently for different countries, and credit card providers are bound to different fees and/or extra charges for international transactions.

It's not a simple solution.
