Whilst I agree that OP could have demanded a warrant in these specific circumstances, folks reading this should be aware that this isn't applicable to all situations and shouldn't be relied upon. For those reading; there are a number of powers in certain circumstances that allow a Police Constable to enter without a warrant. When those circumstances are met then refusing access and demanding a warrant will probably just result in you left with a big old hole in your front door! As it stands it sounds like there was polite conversation between OP and the officer who was then satisfied that no law had been broken and no further action was then taken. I'd suggest putting in a refund claim against Border Force for the destroyed item if you are confident no law was broken.
