Suppose one were to sell their house and leave the UK. Due to loss in confidence in the pound and the banking system, and a feeling of an imminent run on one or both, he converts the money from the sale of his house and his savings, into bullion.
Is there anything he needs to be aware of, walking past UK customs, with half a million pounds worth of precious metals?
How can he make sure there are no problems?
The money of course is 100% legit.
You don't actually pass through UK customs when leaving the country,
although you would still be subject to any relevant laws.
It sounds like you are just asking for trouble by doing things in such
an unusual way. At the very least you should be fully prepared to
explain how you came to be in possession of the bullion, and what the
source your wealth was. Those questions may be asked not just in the
UK but also when you arrive in whatever country you are going to.
The question is, why would you want to do it that way? If you are
emigrating to live somewhere else then you will need money to set up
your new life overseas. Why not just transfer the money legally
through the banking system as most other people would do? If you do
thinks in such a suspicious way then you are only going to attract
attention to yourself.
How about telling us what you're really up to? You're not actually
emigrating with the legitimate proceeds of the sale of your own home,
In gold it is about 28Kg in weight (a bag of cement). Ryan Air will
charge half the value in excess baggage charges.
You probably would have lost lose 20% of the value of the house with VAT
charges with the purchase of the precious metal.
You probably would have too much trouble getting it out of the country
but it may mysteriously disappear in transit in other countries.
