I am thinking of carrying a large pile of cash (£10,000 more) to the UK soon. It sounds like passing through Thai and UK customs should not be a problem if the amount is declared in both countries.
I am just a bit worried about depositing the cash into my UK bank account. Does turning up with £10,000 or more look a bit suspicious? Will questions be asked and proof of source of funds needed?
Or can you just feed the money through a cash deposit machine with no questions asked?
Seems like Russian oligarchs can transfer millions with no questions asked, but the little guy gets picked on by bank compliance teams.
